**** BEGIN LOGGING AT Fri Apr 26 02:59:58 2013 Apr 26 03:19:24 emeb_mac: FPGA! Apr 26 03:20:13 Rah! Rah! Apr 26 03:22:28 Hello everyone. Apr 26 03:23:15 Just ordered two of the BB Black. I was thinking of using it as a software TNC for APRS. Has anyone here tried doing this? Apr 26 03:48:41 8 minutes...not quite a record Apr 26 03:49:14 I've just ordered 4 BBB Apr 26 03:49:19 but want 1200 Apr 26 03:50:23 * ka6sox wonders how many Beagles something like Cirque needs. Apr 26 04:01:39 UrbanNightmare: That sounds like a great idea. The PRUs in particular could handle much of the realtime framing so only a dumb modem would be needed externally, not a full TNC. Apr 26 04:01:59 Oh, he's quit, lol. Bah Apr 26 04:03:25 Oh well, ka6sox will understand that line too :P Apr 26 04:23:29 <_av500_> oh, packet radio Apr 26 04:23:40 <_av500_> that'll get my coworker exited Apr 26 05:04:39 YUP Apr 26 05:05:52 the beaglebone.org demo image mirror is broke Apr 26 05:05:54 http://www.beagleboard.org/angstrom-mirror/www.angstrom-distribution.org/demo/beaglebone/ Apr 26 05:06:16 you guys should auotmate that stuff Apr 26 05:10:22 LEARN_TO_SCRIPT, MY repo is working :P Apr 26 05:10:40 and once again...HIT AND RUN! :P Apr 26 05:20:35 so we are revoking his IRC license? Apr 26 05:30:51 ds2, yup Apr 26 06:13:31 hello I was wondering where I can find information on the BeagleBone Capes. specifically the CAD files. i thought I throughly searched the main website and/capes page but I cannot find anything Apr 26 06:20:47 good moaning Apr 26 06:21:27 mgreci: not sure if that is available for all capes, but I'd expect some capes to have that available Apr 26 06:21:56 hello - does the beaglebone black support openmax? Apr 26 06:22:38 moanin dm8tbr Apr 26 06:23:09 mgreci: cad files for what cape? Apr 26 06:25:06 hey, im using a beagleboard with ubuntu 12.04 on it.. have written a c++ code that takes real time video input, but the camera is not getting detected.. pls suggest Apr 26 06:25:31 im using opencv too Apr 26 06:25:36 jvcleave: tried using google? Apr 26 06:25:39 im using opencv too Apr 26 06:25:53 dm8tbr:yeah Apr 26 06:26:31 because searching for am335x and openmax does give you answers Apr 26 06:28:01 the CAD files to build my own cape Apr 26 06:29:01 mgreci: you could ask mranosta1, he's designed a cape or two Apr 26 06:38:51 .what are we arguing about today Apr 26 06:39:46 does the beaglebone black support the coffee-cape? Apr 26 06:40:06 Black Coffee? Apr 26 06:40:13 of course. Apr 26 06:40:15 doh. Apr 26 06:40:20 espresso-cape Apr 26 06:40:28 but it won't compile properly Apr 26 06:40:31 can you help Apr 26 06:40:34 :-) Apr 26 06:40:40 did you get your transmitter fixed? Apr 26 06:40:51 and i need "exact steps" please Apr 26 06:46:45 does the espresso cape come with HTCPCP support for the BBB? Apr 26 06:47:23 morning Apr 26 06:47:49 mrpackethead, yes, I did... Apr 26 06:47:59 and for av500 ofc also a cape that returns 418 Apr 26 06:48:08 yes, there is a difference between 44.1 and 44.0 Apr 26 06:48:10 the espresso-cape does. Apr 26 06:48:16 it works with all kernels Apr 26 06:48:28 it self installs Apr 26 06:48:42 its the cape that does everything you need Apr 26 06:59:00 koen, is there a later cloud9 image than 12days ago for Bone than 4/13/13? Apr 26 07:00:29 jvcleave: no OMX Apr 26 07:00:35 I mean, SW yes, but not HW unit Apr 26 07:01:03 thanks av500 - it wasn't clear Apr 26 07:08:26 dm8tbr, I think that 1200baud APRS isn't even interesting...unless the PRU creates the waveform for the modem.... Apr 26 07:08:55 PRU+DAC Apr 26 07:09:14 av500: so different soc revisions inside am335x? Apr 26 07:09:32 heh, pru-modem :) Apr 26 07:12:23 hi Apr 26 07:12:54 wanted to create a GSoC project Apr 26 07:13:04 anyone intersted Apr 26 07:13:54 follow the guidelines of GSoC Apr 26 07:14:46 disdi: http://elinux.org/BeagleBoard/GSoC Apr 26 07:25:03 p00f Apr 26 07:26:05 nite nite ladies and trolls Apr 26 07:26:15 grr... argh... Apr 26 07:26:35 emeb_mac, is that your troll imitation? Apr 26 07:26:41 ya Apr 26 07:27:23 I give it an 8 but I can't dance to it. Apr 26 07:29:23 ka6sox-away: no, but you can opkg update stuff when needed Apr 26 07:29:58 koen, kk..thanks Apr 26 07:40:04 goodmorning Apr 26 07:55:18 moining Apr 26 07:55:45 kalimera Apr 26 07:59:45 hey, are you sure there are no lazy genes in you? Apr 26 08:01:43 only ouzo genes.# Apr 26 08:01:43 If he has.... he's most likely too lazy to look for them... Apr 26 08:05:12 tgif Apr 26 08:09:14 Hey can anyone tell me where can i get a an xM in or near Pakistan? Apr 26 08:10:21 I am doing my masters' thesis and I want to setup a radio on beagleboard using OSSIE Apr 26 08:10:53 http://beagleboard.org/Products/BeagleBoard-xM Apr 26 08:11:10 there is a list of distributors Apr 26 08:13:54 i can also offer a distribution of lists, if somebody desires so. Apr 26 08:46:44 They never stay for more than about 2.1seconds Apr 26 08:47:27 I feel used Apr 26 08:47:43 stay around for long enough to do their dirty work, and then poof, gone Apr 26 08:57:54 av500: kalimero? Apr 26 08:59:38 no Apr 26 09:04:27 instant-cape Apr 26 09:04:46 instant-coffee-cape Apr 26 09:04:51 panto: can you do my homework for me Apr 26 09:05:02 I can, but I charge by the hour Apr 26 09:05:14 mranosta1 doesnt love me any more Apr 26 09:05:24 he used to do my homework, but ... Apr 26 09:05:41 he's at Intel, now, doing Tizen & microcode Apr 26 09:06:38 * panto has spend a whole day yesterday just to get a single register to be written properly Apr 26 09:07:57 panto: ive been there, it sucks Apr 26 09:12:22 panto: so if you write 2 register today you have increased productivity with 100%! Apr 26 09:12:35 that's one way to look at it Apr 26 09:12:38 panto: fwiw, wifi cape also needs different clocks on clkout2 Apr 26 09:12:42 the other way is through a beer glass :) Apr 26 09:12:57 koen, I think I've fixed that semi-properly Apr 26 09:13:11 there are gaping holes in the clk api Apr 26 09:13:51 it's geared for the on SoC clock network, but when you try to use it for internally generated clocks for arbitrary drivers it falls down Apr 26 09:18:20 * tsjsieb bought thee bbb Apr 26 09:18:28 can I make a mediacenter now? Apr 26 09:18:51 ow wait, someone said yesterday trolling was only allowed between 2 and 4 pm :( Apr 26 09:19:34 but a coffee-cape is an option, though I dont want an instant version Apr 26 09:21:06 Is it a problem if the coffee-cape is 40x40x90 cm and completely surrounds the bbb? Apr 26 09:21:25 well, I wouldn't mind making a nice espresso machine with the bone :) Apr 26 09:21:29 * panto is a coffee addict Apr 26 09:21:38 what about components though Apr 26 09:21:49 what would you need if your were to build it from scratch? Apr 26 09:22:04 i.e. no repossessed old coffee machine Apr 26 09:24:24 http://www.espressoparts.com Apr 26 09:24:27 thank you internets Apr 26 09:26:32 * tsjsieb works at a coffee-machines manufacturer :p parts won't be a problem Apr 26 09:29:02 tsjsieb: which one? Apr 26 09:29:26 oh, nice Apr 26 09:29:44 tsjsieb, I can relieve you from spare parts :) Apr 26 09:29:55 a small one: dejongduke.nl Apr 26 09:36:25 panto, mdp: LOL @ the wl12xx patches Apr 26 09:36:47 Tony hacks board-generic.c to make it work with DT Apr 26 09:37:08 but good coffee is most of the time not a problem here (until we're trying some nice new features on the internal machiens off-course :p) Apr 26 09:37:12 koen: where? Apr 26 09:37:20 linux-omap ml Apr 26 09:37:29 koen: actually, I'm all for adding temporary non-DT registration to board-generic until driver is converted to DT Apr 26 09:37:45 https://patchwork.kernel.org/patch/2490691/ Apr 26 09:37:48 koen: it would force people into using DT and would make it easier to see how nonsensical hwmod is Apr 26 09:38:15 koen: not to mention that by forcing people to use DT, we will find out about its limitations much quicker ;-) Apr 26 09:38:23 felipebalbi: to get things working board-generic hacks are OK Apr 26 09:38:48 but TII only uses board-generic hacks to develop drivers for DT only platforms Apr 26 09:38:53 which means shit doesn't work Apr 26 09:39:14 ADC driver gained working DT bindings in v10 of the patchset Apr 26 09:39:20 koen: right... yet another reason to force everybody do use DT-only and delete all other board-files :p Apr 26 09:39:49 koen: liked your question about OMAP3-based platforms :-) Apr 26 09:40:03 although that TII problem could have easily been avoided if they would publish the actual tree they test with Apr 26 09:40:22 I'm trying to get my beagle classic and xM to work with .39 Apr 26 09:40:25 3.9 that is Apr 26 09:40:32 :- Apr 26 09:40:33 ) Apr 26 09:40:54 I guess that useless omap2_defconfig works, people get serial console Apr 26 09:40:57 beyond that... Apr 26 09:41:16 I see Roger Q posted more DT patches, need to try those Apr 26 09:41:49 yeah, Roger has been doing good work. USB Host is quite a difficult part (considering all the hw erratas, and the crappy code which was written long ago) Apr 26 09:42:13 "there's an if() in my boardfile, now what?" Apr 26 09:44:36 heh, some guy asking me to queue patches for v3.11 Apr 26 09:44:40 maybe we can use >600Mhz on dm3730 with 3.11 :) Apr 26 09:44:42 we didn't even open v3.10 merge window yet Apr 26 09:44:57 yes, dmack Apr 26 09:45:03 he's being cautious :) Apr 26 09:45:05 :-p Apr 26 09:46:49 espresso-cape Apr 26 09:47:04 * koen looks closer at https://patchwork.kernel.org/patch/2490691/ Apr 26 09:47:20 for beagle* we need both clocks Apr 26 09:47:30 since there are wl1271 and wl1273 boards Apr 26 09:47:55 i'm glad i use begleian.. it just works Apr 26 09:47:57 :-) Apr 26 09:48:00 iirc panda classic uses wl1271 Apr 26 09:48:07 koen: yes Apr 26 09:48:22 koen: but how do we plan to add support for such diferences ? all via dt overlays ? Apr 26 09:48:38 yes, DT overlays Apr 26 09:49:15 koen: alright Apr 26 09:49:20 or making a DT for every beagle+cape+cape+cape+cape permutation Apr 26 09:50:11 last year Tony suggested generating a DT in userspace after probing the hw and rebooting Apr 26 09:50:19 I nearly implemented that Apr 26 09:50:47 koen: yeah, DT for all combinations won't scale Apr 26 09:51:13 askig what might be a stupid question... why can't capes be registered, with a unique serial.. and then the kernel can fiture out whats plugged in at boot time Apr 26 09:51:23 and set up the right DT? Apr 26 09:51:58 maybe not a unique "serial", but a unique "cape-id" Apr 26 09:52:09 that's what it's doing with DT overlays Apr 26 09:52:15 put capes on CAN bus and they can hotplug :-D Apr 26 09:52:20 and in the boardfile with 3.2 Apr 26 09:52:28 check partnumber, do stuff Apr 26 09:52:31 so, the problem is? Apr 26 09:52:43 no boardfiles allowed anymore Apr 26 09:52:48 and no DT overlays in mainline Apr 26 09:52:55 what is a boardfile? Apr 26 09:53:16 felipebalbi, the stuff I did for clockout2 would work for the wl12xx case I think Apr 26 09:53:16 hmm.. so PowerVR will likely not get an OpenVR project... too bad Apr 26 09:53:23 seems like TI's lacking behind on the graphics part Apr 26 09:53:29 and why was DT overlays taken out? Apr 26 09:53:36 panto: cool, will look at that Apr 26 09:53:41 mrpackethead: https://github.com/koenkooi/linux/blob/linux-ti33x-psp-3.2.34-r18a%2Bgitr720e07b4c1f687b61b147b31c698cb6816d72f01/arch/arm/mach-omap2/board-am335xevm.c Apr 26 09:54:16 mrpackethead: panto invented DT overlays recently, upstream is still debating the colour the DT shed needs to be Apr 26 09:54:19 felipebalbi: Imagination did the "sensible" (for them) thing of poisoning as many people as possible with an NDA Apr 26 09:54:37 right. Apr 26 09:54:48 upstream being the Linux kernal club? Apr 26 09:55:00 and the DT standard maintainers Apr 26 09:55:11 XorA: right :-) Apr 26 09:55:15 DT-2 standard? Apr 26 09:55:24 lol. Apr 26 09:55:31 felipebalbi: reading between the lines: DT only boot doesn't work for any TI chip in mainline currently Apr 26 09:55:31 i am currently listening to a debate on standards Apr 26 09:55:36 its riviting Apr 26 09:55:43 trying to get 20 people ont eh same page Apr 26 09:55:49 there's so many of them Apr 26 09:55:56 mrpackethead: you know, standards are like assholes, everyone has one and they usually stink Apr 26 09:55:58 perhaps there should be a standard of standards Apr 26 09:56:08 its all ok, we can switch to ACPI soon ;-) Apr 26 09:56:32 if you think DT sucks, wait until you see ACPI Apr 26 09:56:39 this is why rapsberry was so popular Apr 26 09:56:42 panto: I am working on ACPI Apr 26 09:56:44 bcuase all this was hiddne Apr 26 09:56:46 I expect horrible horrible stories Apr 26 09:56:51 and no-body worried about it Apr 26 09:56:52 XorA, my sympathies :) Apr 26 09:56:52 :-) Apr 26 09:57:22 blink some leds with python! and sell 1M raspberry Pi's Apr 26 09:57:28 mrpackethead: people don't use platform devices on r-pi, they just bitback it with gpio from userspace Apr 26 09:57:32 (I'm not kidding) Apr 26 09:57:42 absolutely Apr 26 09:57:44 it's one way to get rid of unsold stock of chips Apr 26 09:57:59 you dont' have to be 'good' to sell somethign Apr 26 09:58:04 you jsut have to have a good story Apr 26 09:58:12 step one: fuck up production, get left with 2M chips Apr 26 09:58:19 step two: write them off Apr 26 09:58:33 step three: sell them to a charity, deduct it from taxes Apr 26 09:58:36 well, why can't we do that with some TI chips then :) Apr 26 09:58:58 * panto starts a 'cheap engineers need cheap parts too' charity Apr 26 09:59:04 step three: find some guy called Eben Apr 26 09:59:08 trollboard Apr 26 09:59:28 eben is that even a real name Apr 26 09:59:43 what happens to PI, when they run out of chips Apr 26 09:59:44 step four: play on the people of Englands abilities to ignore anything bad that was made it their country Apr 26 09:59:50 it's a Ben that's e'lectronic Apr 26 10:00:18 jackmitchell: isn't that "everything" minus rhubarb crumbles? Apr 26 10:00:43 that's not completely accurate Apr 26 10:00:51 they do have kept all the niche industries Apr 26 10:00:55 * koen watches PRSERV move PR backwards again Apr 26 10:00:59 but no mass production Apr 26 10:01:04 ERROR: Package version for package gtk-theme-thinice went backwards which would break package feeds from (0:2.20.2-r3.8 to 0:2.20.2-r3.3) Apr 26 10:01:10 koen: what are you trying to say?! Bad things come out of my country, but the RasPi was a first of its kind innovation!!! :P Apr 26 10:01:37 jackmitchell, bring back Lucas electronics :) Apr 26 10:01:40 acuallu jack, tehres been lots of low cost linux stuff Apr 26 10:01:58 * koen used to work for TI UK and has stockholm syndrome for british cuisine now Apr 26 10:02:01 mrpackethead: I'll use my tags next time :P Apr 26 10:02:26 http://www.mez.co.uk/lucas.html Apr 26 10:02:44 the good thing is that BBB, is'nt going to make a good media center Apr 26 10:02:45 horrah. Apr 26 10:02:58 so, we dont' have to help the world enterain itself Apr 26 10:03:09 the bbb would have made a good mediacentre 10 years ago Apr 26 10:03:21 though it woudl make an aweome robot controller Apr 26 10:03:21 QCIF ftw! Apr 26 10:03:25 well, not everything needs to be 1080p Apr 26 10:03:34 6 axis robot that and pick up dvd's Apr 26 10:03:43 koen: jkridner can we have: "no it does not do OMX 1080p" on the BBB website? Apr 26 10:03:44 and insert them into dvd player and press paly Apr 26 10:03:44 :-) Apr 26 10:03:45 I still have hopes it will do 720p :) Apr 26 10:03:49 sure Apr 26 10:03:52 even 1080p Apr 26 10:03:54 5 fps Apr 26 10:04:08 can't output 1080p :) Apr 26 10:04:22 when they white lable teh bbb Apr 26 10:04:23 sure Apr 26 10:04:30 i'll ask them to take off the HDMI stuff Apr 26 10:04:32 has anyone here every played with MALI ? Apr 26 10:04:32 just not all at once Apr 26 10:04:39 I wonder if the open source drivers are all that good Apr 26 10:04:39 the country? Apr 26 10:04:43 ah Apr 26 10:04:47 becuase i dont' need any video at all Apr 26 10:04:48 ask Luc Apr 26 10:04:52 thats what my ipad is for Apr 26 10:04:54 :-) Apr 26 10:06:25 http://limadriver.org/ - "2013-02-02: Libv talks about Open ARM GPU drivers at FOSDEM" Apr 26 10:06:42 "Talking about it" suggests that it's early days :P Apr 26 10:06:57 he showed quake3 running Apr 26 10:07:08 dm8tbr and av500 were there to witness it Apr 26 10:07:17 tbr was Apr 26 10:07:20 And "public went wild" Apr 26 10:07:20 * koen was in the other building eating waffles Apr 26 10:07:21 I missed the talk this year Apr 26 10:07:23 * fiola giggles Apr 26 10:08:05 felipebalbi: http://blog.emmanueldeloget.com/index.php?post/2013/03/08/The-SoC-GPU-driver-interview Apr 26 10:08:08 you saw that? Apr 26 10:08:36 av500: koen posted on g+ Apr 26 10:08:42 av500: was reading it earlier today Apr 26 10:08:47 powervr? crickets... Apr 26 10:12:00 * koen is having a call with TI to discuss "use cases" for having the powervr sources Apr 26 10:12:13 I don't know what it is with people Apr 26 10:12:21 what use cases you dolts? Apr 26 10:12:28 use cases for open sourcing Apr 26 10:12:36 how about making the stupid gpu work out of the box Apr 26 10:12:37 koen: use case, a driver that does not immediately crash :-D Apr 26 10:12:37 I wouldn't know what to say Apr 26 10:12:44 I outline the usecases in the start of the email/bugreport and after a while someone will show up saying "please mention any use cases, ktnxbye" Apr 26 10:13:10 biot: not opensources, having nda to get them Apr 26 10:13:35 wtf do they think those sources contain? Apr 26 10:13:37 oh hell Apr 26 10:14:05 we know the code is a horrible mix of HAL + studlyCaps Apr 26 10:14:06 3rd time I go through the process Apr 26 10:14:10 was approved twice before Apr 26 10:14:24 Imagination bascially said to me they would opensource if someone paid them, what they didn't say was how much $$$ :-D Apr 26 10:14:29 Use case: unpaid workers fix and improve TI code until TI has world domination? Apr 26 10:15:04 fiola: that's not very nice :-( there are many doing good work here Apr 26 10:15:17 granted, the amount of people doing bad code is larger, still Apr 26 10:15:19 :-p Apr 26 10:16:34 fiola: there are vendors doing good code on their own? Apr 26 10:16:36 felipebalbi: More eyeballs and hands tends to improve things generally. Admittedly it's chaos, but things do improve. Apr 26 10:16:55 XorA: would be cool to start a Kickstarter project to pay imagination to open source everything about pvr Apr 26 10:17:08 docs would be more usefull than code I guess Apr 26 10:17:10 fiola: I rather have a small team of geniuses then a large team of mediocres Apr 26 10:17:15 unless you want bleeding eyeballs Apr 26 10:17:59 felipebalbi: hehe, good plan Apr 26 10:18:09 dlg: They're probably rare. nVidia seems to manage to produce efficient drivers that only rarely crash, but there are far more examples of bad code from companies. Apr 26 10:19:28 is there any info on when Beaglebone black will be avaliable for shipment? Apr 26 10:19:35 bbone, yes. there is Apr 26 10:19:41 Is on all the web site Apr 26 10:19:59 XorA: 10 bucks or more -> you get a thank you email; 50 bucks or more -> you get a t-shirt; 100 bucks or more -> you get a pandaboard; 500 bucks or more -> you get beaglebone, bb black, pandaboard, beagle xm...; 10000 or more -> you get access to RTL :-p Apr 26 10:20:03 hah Apr 26 10:20:47 any distibutors that are faster than others? Apr 26 10:21:04 (particualary in EU) Apr 26 10:21:07 felipebalbi: Open source isn't "a large team of mediocres" though. It's a colossal team of assorted people, including brilliant geniuses and rampant nutters. The trick is to have the geniuses reject bad commits, and revoke commit rights to people who repeatedly demonstrate their stupidity. Apr 26 10:21:25 drop koen €1,000,000 and Im sure he will hand deliver a necrotic dog :-D Apr 26 10:21:31 fiola: and when did I say open source was made of a large team of mediocres ? Apr 26 10:21:40 fun Apr 26 10:21:51 I'm battling with china to give me a file that is under GPL Apr 26 10:21:55 I mean I have the file Apr 26 10:21:59 but not from them Apr 26 10:22:07 and it says GPL in the header Apr 26 10:22:15 GPL warez always amuses me :-D Apr 26 10:22:23 so I am telling them to look into the file they do not want to give me Apr 26 10:22:24 felipebalbi: I inferred it from " I rather have a small team of geniuses then a large team of mediocres". Who did you mean by "large team of mediocres" then? Apr 26 10:22:26 and see the GPL header Apr 26 10:24:01 fiola: nowhere in that sentence I'm stating that open source is composed of a team of mediocres. Merely I said that if I had the choice, I'd rather have a small team of geniuses. From a corporate point of view, it's best to get results with a small team of brilliant people than it is to coordinate a large and mediocre team. Apr 26 10:24:16 fiola: still, I'm not saying anywhere that I'm applying that to any particular team Apr 26 10:25:12 the mediocre people are sent away in the first ark ship Apr 26 10:25:17 solved Apr 26 10:25:25 av500: :-) Apr 26 10:25:30 Uh ... OK. I guess you were talking hypothetically then. :P Fair enough, I too wouldn't like a "large team of mediocres" :-))) Apr 26 10:25:37 av500, astral goats are coming Apr 26 10:25:48 fiola: yep, that's the word I was looking for... "hypthetically" ;-) Apr 26 10:26:00 * fiola lols Apr 26 10:26:06 hynotically Apr 26 10:27:04 +o Apr 26 10:27:37 hinaughtycally? Apr 26 10:28:22 * tsjsieb calls Apr 26 10:29:12 hootically Apr 26 10:30:15 they hang up and tell me to go work :( Apr 26 10:32:34 hootenanny Apr 26 10:32:43 Friday! Apr 26 10:32:53 +1 Apr 26 10:33:16 fry-day. Apr 26 10:33:42 FRI2-day in teh other channel Apr 26 10:38:43 koen: in meta-beagleboard, beaglebone.conf has the following: Apr 26 10:38:45 common-bsp/conf/machine/beaglebone.conf:IMAGE_FSTYPES_append = " tar.xz " Apr 26 10:38:53 hi mdp Apr 26 10:39:19 now, I don't want a tar.xz image; should it be IMAGE_FSTYPES += " tar.xz"? Apr 26 10:39:38 so I can override it in my distro conf with IMAGE_FSTYPES = "tar.gz" Apr 26 10:40:44 fri-lo panto Apr 26 10:41:19 almost saturdya Apr 26 10:45:55 Sounds like Russian :P Apr 26 10:50:59 almost monday! Apr 26 10:51:11 mondya Apr 26 10:51:42 My Russian is getting better by the minute :P Apr 26 11:05:01 http://www.ismytwitterpasswordsecure.com/ Apr 26 11:05:07 wtf Apr 26 11:05:54 http://26-26-54.hardwarebug.org/18 Apr 26 11:06:15 * mru hates when "copy link" doesn't in fact copy the link at all Apr 26 11:44:15 hi Apr 26 11:45:02 I am interested in gsoc project " Library of Arduino-compatible function for Linux" Apr 26 11:45:27 send a mail to the beagleboard-gsoc list Apr 26 11:45:32 that's the best way :) Apr 26 11:46:15 koen: okay Apr 26 11:51:36 fiola: it really was a wow moment when he switched from slowly rotating textured cube to Q3 Apr 26 11:52:21 fiola: letothe2nd was there too, and I actually told him 'and now he'll switch from that to Doom3' and we chuckled, then our jaws dropped Apr 26 11:54:50 KotH: posted Apr 26 11:57:43 dm8tbr: Haha, that was a cool move, from rotating cube to Q3, not surprised at the applause :P Apr 26 11:58:05 av500: KotH doesn't g+ Apr 26 11:58:47 google is ebil, and g+ is ebil+ :P Apr 26 12:02:15 and you can't even spell evil Apr 26 12:05:34 evil and ebil aren't the same things, check your urban dictionary :P Apr 26 12:10:46 saying ebil in stead of evil is evil, so yes, ebil=evil Apr 26 12:12:03 Oh I grant you that "saying ebil in stead of evil is evil", but your second statement doesn't follow from that as a premise :P Apr 26 12:14:05 no it's not, that's the evil part of it Apr 26 12:14:08 ;) Apr 26 12:14:57 Oh I see, you made an ebil induction. That's a definite touche' ^_^ Apr 26 12:21:48 I've just jumped on this, I've been waiting for something similar (and of reasonable cost) for a while: http://www.kickstarter.com/projects/woodenshark/lightpack-ambient-backlight-for-your-displays Apr 26 12:23:22 jackmitchell: nice, but fail Apr 26 12:23:29 it does not work without a PC Apr 26 12:23:46 av500: I know, I pretty much solely use a mediaserver for my big tv Apr 26 12:23:53 s/server/player Apr 26 12:24:07 so it's a 4-pixel display that's blurry to boot Apr 26 12:24:10 * mru is not impressed Apr 26 12:24:49 it would be nice as HDMI passthrough Apr 26 12:25:02 I don't think it would be too difficult to add a small convetor Apr 26 12:25:12 but it would need some thinking about Apr 26 12:25:12 hdmi yes Apr 26 12:25:19 since you need HDCP Apr 26 12:25:26 so $$$ and NDA Apr 26 12:25:28 the keys are known now Apr 26 12:25:33 indeed Apr 26 12:25:33 and the protocol is public Apr 26 12:25:49 ah yes, I forgot about HDCP Apr 26 12:26:03 still you need to process the hdmi data stream Apr 26 12:26:23 lots of bits per second there Apr 26 12:26:24 it could use the bunnie fpga maybe Apr 26 12:26:33 a little passthrough reader with USB would do it I think, but I don't know about the HDCP side of it Apr 26 12:26:40 usb? Apr 26 12:27:01 hdmi in, hdmi out, usb out to the box Apr 26 12:27:36 it's already pretty much in production, so it would be a fairly big hardware change Apr 26 12:27:38 just crack open the tv and intercept the lcd panel signals Apr 26 12:27:42 no hdcp there Apr 26 12:28:01 yep Apr 26 12:28:07 put it on craskstarter Apr 26 12:28:29 jackmitchell: extracting the color info from hdmi is a challenge by itself Apr 26 12:28:37 not a retrofit on that thing Apr 26 12:28:53 av500: yeah, I don't know much about it, was just hypothesising Apr 26 12:29:07 also fun when their solution falls flat on Windows when e.g. using netflix Apr 26 12:29:17 since you dont get access to the pixel data :) Apr 26 12:29:33 av500: heh, more pain for those poor windows user Apr 26 12:29:46 well, for linux its easier, no netflix at all :) Apr 26 12:30:47 what about evil people like me using evil gadgets like ps3? Apr 26 12:31:40 indeed, free from the shackles of copyrighted DRM enforced content! Apr 26 12:32:00 free from hassle Apr 26 12:32:03 it just works Apr 26 12:32:24 I think it's mainly a device aimed at people with XBMC machines Apr 26 12:32:34 mru: well, no ambilight for you Apr 26 12:32:37 unless in the TV Apr 26 12:32:39 so how does that thing work? software screengrabbing? Apr 26 12:32:44 I guess so Apr 26 12:32:54 or on the gpu Apr 26 12:32:59 still sw Apr 26 12:33:20 I'd also guess that philips has a few patents on amiblight.... Apr 26 12:33:38 there is a little bit on it here: https://code.google.com/p/light-pack/w/list Apr 26 12:34:40 if contrast is a problem, I have a cheaper solution: switch on a small lamp a few metres from the tv Apr 26 12:34:56 of course positioned so it doesn't cause glare Apr 26 12:35:00 yes Apr 26 12:35:07 though amibilight is nice Apr 26 12:35:14 ah, they are russian Apr 26 12:35:18 it's a gimmick Apr 26 12:36:04 sure Apr 26 12:36:08 but I like it Apr 26 12:36:33 I saw some of the ambilight tv's once in a shop and they were fun, ever since then I've kept an eye out for something similar Apr 26 12:37:05 EP 1379082 Apr 26 12:37:11 might explain why only philips has it :) Apr 26 12:37:23 what does windows do with analogue outputs when playing protected content? Apr 26 12:37:36 I think it disables them Apr 26 12:37:41 completely? Apr 26 12:37:43 i.e. to can't watch dhcp on s-video Apr 26 12:37:55 s/dhcp/hdcp Apr 26 12:38:06 usually the owners are ok with a low-res unprotected version Apr 26 12:38:08 you just get a black video I think Apr 26 12:38:19 I could be wrong though Apr 26 12:38:33 I know we did that on directv STBs Apr 26 12:38:48 some do also degrade to SD, no? Apr 26 12:38:55 then dtv complained that the picture quality on component out sucked Apr 26 12:39:04 so we removed the downscaling Apr 26 12:39:51 what I'm getting at is, for ambilight purposes, anything resembling the picture will do Apr 26 12:40:22 yes Apr 26 12:40:30 my idea is to aim a webcam at the TV Apr 26 12:40:43 hmm, I wonder how hard it would be to build an analogue ambilight Apr 26 12:40:58 from a couple of light sensors? Apr 26 12:41:37 you need to do averaging as well, depending on the scene I think, so you couldn't have a 1:1 led:sensor Apr 26 12:41:45 you can Apr 26 12:41:51 you aim the sensor at a region Apr 26 12:41:55 that averages Apr 26 12:42:36 yes ok, but you would then need the sensors a few cm from the screen, rather than clipped discretely around the edges Apr 26 12:42:49 depends on the opening angle Apr 26 12:43:00 ceiling-mounted Apr 26 12:43:07 with tele lenses Apr 26 12:43:28 you could build a business around professional installers Apr 26 12:43:34 for sure Apr 26 12:43:51 for phones and tablets you can have people following you around with a lens array Apr 26 12:44:01 for a fee Apr 26 12:44:16 or use gregoire's quadcopter Apr 26 12:44:22 now we are talking Apr 26 12:44:34 and another in front of you for the lights Apr 26 12:47:31 WTH? Farnell has just put the price of BBB up by 3 quid. I wonder if the Pi foundation told them to stop competing with Pi Apr 26 12:48:00 * jackmitchell outraged Apr 26 12:48:21 I wonder why they did that Apr 26 12:49:26 exchange rate Apr 26 12:49:29 bitcoin fell today Apr 26 12:50:23 Dunno, but cutting their own throats, because sales volume vs price curve is exponential, or worse. Apr 26 12:51:46 I'm waiting for Farnel CPC to get them in stock, they're usually a few quid cheaper there Apr 26 12:51:47 fiola: I'll sell you a limited edition A4 for ÂŁ100 Apr 26 12:52:22 lol Apr 26 12:52:24 i'll do it for 95 Apr 26 12:52:27 Try ebay :P Apr 26 12:52:43 or I'll keep it my collection Apr 26 12:52:51 a have a few rare ones Apr 26 12:53:03 av500: got a beagle classic C1D? Apr 26 12:53:17 nah Apr 26 12:53:21 go sell it Apr 26 12:53:32 so rare even av500 doesn't have one Apr 26 12:53:45 I have even older omap3 boards than that Apr 26 12:53:57 the oldest I have is a plain B Apr 26 12:54:02 professional ones Apr 26 12:54:18 Oh, are there boards with BEA61E or similar S/N? Apr 26 12:54:36 get that on your licence plate Apr 26 12:55:07 I wanted av500 on my plates Apr 26 12:55:14 but they said A* is only for motorbiks Apr 26 12:55:16 idiots Apr 26 12:55:24 so get a motorbike Apr 26 12:55:28 nah Apr 26 12:55:28 lol Apr 26 12:55:41 I want to live Apr 26 12:56:13 you live on motorbike too Apr 26 12:56:20 just not as long Apr 26 12:56:25 no, but fasteer Apr 26 12:56:32 so the same amount in the end Apr 26 12:57:24 I guess I prefer the slow death then Apr 26 12:59:21 death is overrated Apr 26 12:59:22 why drag it out? Apr 26 14:52:28 av500: any old SH boards? I still have a few. Apr 26 14:52:49 SH? Apr 26 14:52:55 SuperH Apr 26 14:53:01 I have SH1 EVM Apr 26 14:53:11 and SH4 Apr 26 14:53:53 nice Apr 26 14:53:53 I have an sti7109 (sh4) board Apr 26 14:54:02 unfortunately it has two problems Apr 26 14:54:21 1) it's SH4 Apr 26 14:54:39 a resistor, probably part of the power regulator, gets insanely hot after ~30s Apr 26 14:55:07 only use it on cold days Apr 26 14:55:12 that was #1 Apr 26 14:55:28 2) it has os21 in flash, and I don't have the right jtag to replace it Apr 26 14:55:48 mru: so you have one? Apr 26 14:55:52 why did you want mine then? Apr 26 14:56:11 av500: I didn't, diego did Apr 26 14:56:23 ah right Apr 26 14:56:30 but you didnt mention you already had one Apr 26 14:56:44 I'm sure I have mentioned this board before Apr 26 14:57:11 but as I said, I fear something will burn if I run it for more than a minute or two Apr 26 15:11:19 Just received BB Black. Following Quick Start connected to my PC. PWR LED is lit, status LEDs remain off. No new mass storage device appears on Windows. Have error that no driver found for AM335x USB. Seems to cycle USB connect/disconnect. Is this a hardware failure, or just missing firmware? Should I attempt to flash eMMC? Apr 26 15:11:56 koen: ^^^ Apr 26 15:11:57 can you USB port supply enough power? Apr 26 15:12:04 your* Apr 26 15:12:37 Yes. Works with pcDuino and Raspberry Pi. Also tried external power supply. Still no status LEDs. Apr 26 15:12:42 * mdp considers a separate Black Big Board Apr 26 15:12:52 mdp: a blackboard Apr 26 15:13:07 to coin a term, yes Apr 26 15:13:10 very clever! Apr 26 15:13:24 bgreat: try reflashing eMMC Apr 26 15:13:40 see, onboard storage is a bad idea Apr 26 15:14:01 features are problems Apr 26 15:14:54 Will do. May need to wait till this evening to get home where I have a micro-SD. Unless... Is it possible to flash directly via USB interface? Apr 26 15:15:19 problems are features Apr 26 15:15:40 Crofton|work: that is a clear clue you are a consultant :-D Apr 26 15:15:40 bgreat: theoretically yes, but I never tried Apr 26 15:15:51 XorA: I was about to say that Apr 26 15:16:16 now can someone tell me where I put my QL? Apr 26 15:16:24 I will check TI site for info. Probably simpler to wait until I am home, but I am the impatient sort. :) Thank you. Apr 26 15:19:45 OMG, someody bought one Apr 26 15:21:29 uh oh, impatient + open source = rage Apr 26 15:21:34 ha: printk("Apk didn't start when audio start \n"); Apr 26 15:21:47 hello Apr 26 15:21:56 round 2 Apr 26 15:21:59 kernel is getting androidified Apr 26 15:22:01 i have a question about new beagle black Apr 26 15:22:06 ask Apr 26 15:22:15 i want to use it to build a nas Apr 26 15:22:23 odd thing to do Apr 26 15:22:23 I have a whole bunch of usb hdds Apr 26 15:22:25 and a hub Apr 26 15:22:29 eeeeek Apr 26 15:22:36 asdf__: I suggest real hardware. Apr 26 15:22:40 was thinging about using raspbery pi Apr 26 15:22:45 That is also a bad idea. Apr 26 15:22:56 asdf__: I would look at something with a _least_ a sata port Apr 26 15:23:01 asdf__: usb on rpi has hardware bugs that make it unusable Apr 26 15:23:13 jacekowski: not exactly hardware bugs Apr 26 15:23:19 well, SoC bugs Apr 26 15:23:19 just hardware ill-suited to running linux Apr 26 15:23:32 yes, i know about problems with usb on raspbery pi Apr 26 15:23:39 asdf__: if you want to build a slow nas, go ahead Apr 26 15:23:44 cause they use lan off the usb... Apr 26 15:23:46 if you run an rtos with guaranteed 1ms interrupt response time, you're all set Apr 26 15:23:59 so the question that I have Apr 26 15:24:02 mru: i've read somewhere saying that nobody used usb on that soc before Apr 26 15:24:07 do you know if lan port Apr 26 15:24:13 jacekowski: that may well be true Apr 26 15:24:23 on the new beagle black Apr 26 15:24:27 has its own chip Apr 26 15:24:30 mru: and that there are some hardware bugs in there Apr 26 15:24:37 asdf__: iirc it's usb to eth chip Apr 26 15:24:37 or is it running off the usb? Apr 26 15:24:39 asdf__: lan is part of the SoC Apr 26 15:24:42 not on usb Apr 26 15:24:44 asdf__: both bones have a dedicated ethernet port Apr 26 15:24:51 when did that happen? Apr 26 15:25:03 bb had usb to eth chip Apr 26 15:25:06 beagle-xm has usb-eth Apr 26 15:25:11 classic has no eth at all Apr 26 15:25:13 so is it a usb to eth chip Apr 26 15:25:17 no Apr 26 15:25:18 No. Apr 26 15:25:19 or a dedicated eth? Apr 26 15:25:19 not the bones Apr 26 15:25:23 It is built into the ARM. Apr 26 15:25:25 the bones have on-chip emac Apr 26 15:25:27 asdf__: part of the SoC Apr 26 15:25:27 asdf__: beaglebone has dedicated eth Apr 26 15:25:34 agmlego: no, not part of the _arm_ Apr 26 15:25:42 Er, SoC. Apr 26 15:25:46 is it gigabit or 100? Apr 26 15:25:50 jacekowski: Yes. Apr 26 15:25:56 10/100 from what I read... Apr 26 15:25:59 yes gigabit or yes 100? Apr 26 15:26:03 another question Apr 26 15:26:05 yes gig or 100 Apr 26 15:26:17 yes gigabit? Apr 26 15:26:19 do you know if there are any problems using a USB hub? Apr 26 15:26:22 its a 10/100 Apr 26 15:26:24 not a gb Apr 26 15:26:29 according to specs Apr 26 15:26:32 asdf__: There are many problems using USB hubs. Apr 26 15:26:39 Just not any that are specific with the bones. Apr 26 15:26:50 asdf__: connecting hdds using usb hub is bad Apr 26 15:26:52 Hubs suck. Apr 26 15:26:53 and slow Apr 26 15:26:55 very slow Apr 26 15:27:00 asdf__: your nas will be slow Apr 26 15:27:12 if you can live with that, go aheads Apr 26 15:27:14 -s Apr 26 15:27:17 the bone has a gb emac with a 10/100 phy Apr 26 15:27:24 up until yesterday I was using dd-wrt for a nas... Apr 26 15:27:45 isn't that a router thing? Apr 26 15:27:48 yes Apr 26 15:27:51 it is Apr 26 15:27:54 why use that on a nas? Apr 26 15:28:06 cause my router had usb ports Apr 26 15:28:26 and I just used that as a nas... Apr 26 15:28:31 instead of buying a new one Apr 26 15:28:46 router hw does not make for a good nas Apr 26 15:28:51 btw. you can get netgear readynas duo for like $99 Apr 26 15:28:55 with real sata ports Apr 26 15:28:58 and gigabit ethernet Apr 26 15:29:00 and fast SoC Apr 26 15:29:21 but I alrready have like 6 or 7 USB HDDs Apr 26 15:29:23 or you can buy a small form factor pc and build whatever you want Apr 26 15:29:29 asdf__: you can take those apart Apr 26 15:29:31 that I was using in my router/nas Apr 26 15:29:36 asdf__: then build a slow nas Apr 26 15:29:41 its fine Apr 26 15:29:53 yes, I was thinking about small pc Apr 26 15:30:07 but I like the arm for its power (as in electricity usage) Apr 26 15:30:12 my router is a small pc Apr 26 15:30:17 as said Apr 26 15:30:24 if you can live with the slow speed, go ahead Apr 26 15:30:24 3 onboard nics and pci wifi card Apr 26 15:31:06 thanks. so just to confirm - the new beagle has a dedicated chip and not usb to lan Apr 26 15:31:12 right? Apr 26 15:31:25 yes, both white and black bone has separate emac Apr 26 15:31:29 have Apr 26 15:31:41 yes Apr 26 15:31:52 not a dedicated chip Apr 26 15:31:56 its part of the SoC Apr 26 15:31:58 what is emac? Apr 26 15:32:02 we said that a few times Apr 26 15:32:05 it Apr 26 15:32:07 is Apr 26 15:32:08 part Apr 26 15:32:10 of Apr 26 15:32:11 the Apr 26 15:32:13 soC Apr 26 15:32:25 built-in Apr 26 15:32:47 thanks. I wanted to know what emac stands for Apr 26 15:32:53 just like soc meand system on a chip Apr 26 15:33:02 e-something MAC :) Apr 26 15:33:18 embedded Apr 26 15:33:21 exceptionnal Apr 26 15:33:23 e-something m-something a-something c-something Apr 26 15:33:25 extra Apr 26 15:33:30 ew Apr 26 15:33:31 thank you all for your help Apr 26 15:33:40 eMac was one of those Macs built inside the monitor :-D Apr 26 15:34:00 XorA: no, that's imac Apr 26 15:34:04 emac is the separate ones Apr 26 15:34:08 internal vs external Apr 26 15:34:32 mru: pretty sure the original CRT based ones were eMac Apr 26 15:35:06 damn, I'd forgotten about those Apr 26 15:35:19 stop ruining my logic with facts Apr 26 15:35:28 +1 Apr 26 15:35:32 * XorA deletes last couple of lines Apr 26 15:40:30 * mdp considers fixing that statement Apr 26 15:40:52 http://26-26-54.hardwarebug.org/128 Apr 26 15:46:08 av500, the problem about is that the "e" stands for existential ... self-explaining all the confusion Apr 26 15:46:15 s/about/above/ Apr 26 15:48:16 so mdp is it Friday up in OH yet? Apr 26 15:48:53 yeah, in particular this week, it couldn't have come sooner :( Apr 26 15:49:12 and things aren't generally that bad thankfully Apr 26 16:02:36 finish!!! Apr 26 16:03:26 hello guys, i'm wondering where i can find description of pins for beaglebone black? Apr 26 16:03:44 in the SRM Apr 26 16:04:20 ->learn more->hardware specs etc.. Apr 26 16:04:25 on the website Apr 26 16:04:51 koen: hint, I would put a link to the SRM PDF on the front page.... Apr 26 16:05:43 nardev: Also good information here: http://elinux.org/BeagleBone Apr 26 16:05:44 a live tile Apr 26 16:06:00 links are so last century Apr 26 16:06:50 yeah Apr 26 16:07:08 Digikey shipped my 'Black :-) Apr 26 16:07:08

EXACT STEPS

Apr 26 16:09:18 alan_o: is it same as beaglebone? Apr 26 16:13:55 ok, what did I miss? Apr 26 16:14:06 is it eternal September here in #beagle Apr 26 16:15:18 panto: hades maybe Apr 26 16:18:53 morn' kkeller Apr 26 16:19:33 morning mranostay - happy Friday Apr 26 16:19:55 everyday this week is a Friday :P Apr 26 16:20:11 short timer talk! Apr 26 16:22:31 hi mag Apr 26 16:22:32 hi kkeller Apr 26 16:23:23 hello Panto - happy Friday evening to you ! Apr 26 16:25:26 it's almost beer o'clock! Apr 26 16:25:47 and I've only contemplated throwing the device out the window only twice! Apr 26 16:25:53 tgif Apr 26 16:29:58 since the bblack is now 1ghz, does that mean the PRU runs at >200mhz? Apr 26 16:30:15 277mhz? Apr 26 16:31:29 cmicali, no Apr 26 16:31:43 :( a guy can dream Apr 26 16:34:00 perhaps you could modify the external crystal, (and then mess with the clock network defs) and get it higher Apr 26 16:37:11 interesting, probably outside of my comfort zone Apr 26 16:39:28 let's make a wishlist Apr 26 16:40:22 I wish for a PRU integration with all 32 (16/16) PRU signals exposed to balls Apr 26 16:40:47 whose balls ? Apr 26 16:40:53 I was waiting for that Apr 26 16:41:01 * mdp hands ogra_ a Friday T-Shirt Apr 26 16:41:06 yeah, i'm easy for that Apr 26 16:41:07 +1 on that Apr 26 16:41:25 i wish for adjustable pru clock multiplier (so > 200mhz) Apr 26 16:41:37 ogra_, I carefully chose "exposed" to lure you in Apr 26 16:41:48 heh Apr 26 16:42:38 heh i was just being irritated everywhere is out of stock of bblack Apr 26 16:42:47 and adafruit sent me an email at that exact moment saying they have them in stock Apr 26 16:42:57 cmicali, yes., then we want an 8 PRU version of it Apr 26 16:43:06 why stop at 8 Apr 26 16:43:16 2 PRUSSes is "ok" but we really want more cores inside the one PRUSS Apr 26 16:43:19 actually even just another 2 Apr 26 16:43:23 and more pins Apr 26 16:43:23 would be amazing Apr 26 16:43:51 just more pins would be enough Apr 26 16:44:10 once we get there, then, just like bcm2835, the crappy arm core will be a slave to the coprocessor ;) Apr 26 16:44:45 rom code can move to the PRU Apr 26 16:45:19 just unboxed my shiny new beaglebone2 from nawark.com hooked to my imac as 192.168.7.2 but WHAT IS THE ROOT PASSWORD? Apr 26 16:45:44 try no password Apr 26 16:45:53 lol Apr 26 16:45:53 hunter2 Apr 26 16:45:54 (just press enter) Apr 26 16:46:05 hahaha hunter2 Apr 26 16:46:16 heh Apr 26 16:46:26 tried no password, tried admin, tried secret Apr 26 16:46:41 possibly the best one on bash Apr 26 16:46:43 tried online docs, tried built-in docs Apr 26 16:46:51 root? Apr 26 16:47:10 this is cruel, it's no nice and shiny and black. I feel like its taunting me Apr 26 16:47:26 iirc on the white bone it was just no password, did it change in the latest image? Apr 26 16:47:29 are you using a serial console cable? Apr 26 16:47:41 there is no password for root Apr 26 16:48:15 zeebar, are you sshing in? Apr 26 16:48:37 this is ssh over network over usb. Apr 26 16:48:58 mmm...usb Apr 26 16:49:21 ssh root@$BONEADDR ? Apr 26 16:50:13 if you ssh in, by default it will try to use your username Apr 26 16:50:51 ssh 192.168.7.1 -l root Apr 26 16:51:21 did you try to use ethernet? Apr 26 16:51:42 this is pretty weird Apr 26 16:52:10 might sound crazy but are you sure it's the bone's ip and not another machine? Apr 26 16:54:57 has anybody here gotten a recent beaglebone black? I ordered mine within 10 mins of getting the email notification and it arrived overnight. maybe i should come back tomorrow when everybody else got theirs? Apr 26 16:55:21 zeebar, we do have blacks Apr 26 16:55:28 it's a dev channel Apr 26 16:55:51 please try connecting over ethernet Apr 26 16:57:44 ok, trying ethernet Apr 26 16:59:53 Hello, I have a walcharger that reads OUTPUT:3.1-9V 1.5A. Can I use it to power up Beaglebone for required 5V? Apr 26 17:00:26 is the voltage adjustable? Apr 26 17:00:38 there should be a switch on it that lets you select 5V Apr 26 17:01:00 if it's 5V and it fits, it should work Apr 26 17:01:05 but don't blame us if you blow it up :) Apr 26 17:01:37 No, it doesn't have any switch Apr 26 17:02:06 * kkeller thinks Sharma should not use Apr 26 17:02:23 * panto resists trolling urges Apr 26 17:02:51 yeah i'd advise against Apr 26 17:03:16 sharma: order one of these, only $10 http://www.adafruit.com/products/276 Apr 26 17:05:04 Thanks. Can I use 5V usb wall charger? I am not sure if usb port can be used with PC only Apr 26 17:05:24 * cmicali does not know the answer to that Apr 26 17:05:32 panto - ah come on and troll a little, it is friday and beer time already for you Apr 26 17:06:01 ungghhh... the bone sucks cause it can't play my 1080p mkvs ... Apr 26 17:06:29 kkeller, I'm thinking of eevblog Dave's comments about the "impending death" wallwarts from .cn. Apr 26 17:41:04 thank you - root ssh over ethernet without passwd works fine. ssh over usb now also works, was using wrong IP (also reinstalled usb network driver) Apr 26 17:45:27 zeebar, good Apr 26 17:46:46 if (beer_time() == now()) ... Apr 26 17:46:52 cya Apr 26 17:47:39 Font is apparently just Gothic. Apr 26 17:48:05 what font? Apr 26 17:58:07 whats the general consensus these days: raspberry pi vs beagleboard black ? Apr 26 17:58:23 what pi? Apr 26 17:58:27 model 2 Apr 26 17:58:54 oh. i see what you did there. Apr 26 17:59:05 mru: Wrong window. Apr 26 17:59:14 * kkeller adafruit.com just announced stock BBone Black Apr 26 17:59:45 mru: I was describing the font on the lamacoid tags we use at work as an example of a clear, sans-serif, unambigous font. Apr 26 18:00:22 grantsmith: The bone has a significantly better processor, far more GPIO, and is slightly smaller. The pi is $10 cheaper. Apr 26 18:00:49 why did they start selling constants? Apr 26 18:01:10 ds2: which would you rather buy, a constant or a color/ Apr 26 18:01:10 ? Apr 26 18:01:15 ds2: It was an irrational decision. Apr 26 18:01:27 * mru orders a few sqrt(-1) Apr 26 18:01:30 ds2: But they spun it around. Apr 26 18:01:49 mru: I'd be happy to sell you some sqrt(-1) boards Apr 26 18:01:56 ds2: So that they could transcend the bounds oftheir rational sales. Apr 26 18:02:05 * agmlego stops. Apr 26 18:02:08 are those i's or j's? Apr 26 18:02:11 beer Apr 26 18:02:17 * mru demands j Apr 26 18:02:30 j is the real imaginary unit Apr 26 18:02:34 ds2: Does it mattter? A symbol by any other name would be just as complex. Apr 26 18:02:54 alan_o: seeing how panatone is behind colors... definitely colors! Apr 26 18:03:16 what did panto do now? Apr 26 18:05:39 agmlego, thanks Apr 26 18:05:50 kkeller, thanks. purchased :) Apr 26 18:06:44 grantsmith: No problem. Apr 26 18:07:59 grantsmith: you have chosen wisely Apr 26 18:08:26 lol ty Apr 26 18:09:03 my bad - was trying to ssh into my workstation usb link side ip (192.168.7.1) instead of the beagle peer (192.168.7.2) DUH ... root ssh w/ empty pass working fine over ethernet and tcp/usb. THANK YOU Apr 26 18:10:23 does the bb just have one usb slot ? Apr 26 18:10:48 grantsmith: You'll want to check out the SRM Apr 26 18:10:56 srm ? Apr 26 18:11:07 System Reference Manual. Apr 26 18:11:11 ah. Apr 26 18:11:12 It's in a few places: https://www.google.com/search?q=beaglebone+black+srm Apr 26 18:11:38 probably this is the best one http://beagleboard.org/Products/BeagleBone%20Black Apr 26 18:14:03 yeah, just the 1USB port, so i guess i'll need a hub Apr 26 18:14:07 pi has two Apr 26 18:14:27 alan_o: bow before the great SRM Apr 26 18:15:24 grantsmith: bone has real ethernet and proper Linux support for its hardware. Apr 26 18:17:07 grantsmith: I bet the pi usb ports are actually behind a single hub anyway Apr 26 18:17:09 "real ethernet"? Apr 26 18:17:19 as real as it gets Apr 26 18:17:20 grantsmith: As oposed to a USB-Eth chip. Apr 26 18:17:26 oh i see Apr 26 18:20:02 mru: i believe they are Apr 26 18:20:28 probably same chip doing eth Apr 26 18:20:40 mru: *bang* :) Apr 26 18:20:48 smsc95xx no doubt Apr 26 18:31:48 grantsmith: actually, AFAIK, usb isoc urbs don't work in RPI Apr 26 18:32:07 which is a serious problem for anyone doing usb video capture, for instance Apr 26 18:32:17 hwhaa??? Apr 26 18:32:24 <_av500_> back Apr 26 18:32:30 <_av500_> iso does not work on musb either Apr 26 18:32:39 <_av500_> unless that changed in the past year or so Apr 26 18:33:48 iso's a pain in the butt. Apr 26 18:34:15 it seems like half the usb spec is exceptions or extra stuff only for iso endpoints/transactions Apr 26 18:35:01 It would be fun to make an isoc device just to conquer the difficulty. Apr 26 18:35:55 <_av500_> musb is just to attaach a modem... Apr 26 18:35:59 <_av500_> nobody needs iso for that Apr 26 18:36:33 or usb Apr 26 18:38:42 <_av500_> if we had only done high speed DDR3 printer ports... Apr 26 18:41:38 The renaming support in git really irritates me Apr 26 18:42:12 anyone know how i can get in contact with the admin for http://beableboard.org/ ? Apr 26 18:42:20 beableboard? Apr 26 18:42:22 why should an SCM system ever have to rely on heuristics to tell me whether something was moved/renamed. Why can't a move be stored as a move? It makes my head hurt Apr 26 18:42:30 sorry, typo Apr 26 18:42:43 rws: are you looking to sell web hosting services? Apr 26 18:42:50 nope Apr 26 18:42:50 rws: credit card processing? Apr 26 18:42:55 nope Apr 26 18:42:57 rws: insurance? Apr 26 18:43:09 :) Apr 26 18:43:18 rws: he's jkridner on this channel Apr 26 18:43:33 again, no... i have a technical problem with some links from ti.com :) Apr 26 18:52:03 heh 404 errors? Apr 26 18:55:40 Just bought a black and it was shipped yesterday. If i wanted to go about putting Arch Linux Arm on it, would there happen to be information on this somewhere? Apr 26 18:56:00 Or would I be one of the first trying to get Arch running on it Apr 26 18:56:10 Which would make sense Apr 26 18:56:45 does arch have instructions for white bone? Apr 26 18:57:09 absolutely Apr 26 18:57:17 follow those then Apr 26 18:57:28 which was for the sd card, but ok. Sounds good Apr 26 18:57:59 the sd slot is still there Apr 26 18:58:34 yep, but I guess I was thinking I'd want to install it to the 2GB on-chip memory. Is that incorrect? Apr 26 18:58:50 sure you can do that Apr 26 18:58:59 it's emmc so should behave much like an sd card Apr 26 18:59:44 Yep. Ok sweet. Should be a good experiment. I'll be sure to write up results/instructions Apr 26 19:00:18 freidude exclusive tip from me, when you have a sane kernel for a device you can install nearly all distros which supports the architecture Apr 26 19:00:56 sorry for the ingorance, but what's a sane kernel? Apr 26 19:01:01 may be old news - Adafruit says they have BBB in stock -> https://www.adafruit.com/products/1278 Apr 26 19:01:07 freidude: one that works Apr 26 19:01:20 ha, ok Apr 26 19:01:37 freidude: and one that isn't too hacked up by the distro people. Apr 26 19:01:57 ahh yeah. I'm hoping arch should be pretty stable Apr 26 19:02:51 I'll probably hold off for a while, it's just just I'm used to arch, and it's light enough that I don't think I'll need to worry about speed/resources Apr 26 19:22:07 hey, can someone tell me what kind of power supply the BeagleBone black takes, and weather or not it ships in teh box with the BeagleBone? Apr 26 19:22:18 5V Apr 26 19:22:34 it appears to be powerable from USB cable alone in base config Apr 26 19:22:37 <_av500_> yes Apr 26 19:22:42 <_av500_> usb or 5v DC-in Apr 26 19:22:46 <_av500_> no psu in the box Apr 26 19:22:56 okay, thanks guys! Apr 26 19:23:06 <_av500_> np Apr 26 19:23:46 <_av500_> koen: when do you reckon jkridner rise again? Apr 26 19:24:06 is he some kind of phoenix? Apr 26 19:24:41 do you want to burn him down ? Apr 26 19:24:50 to try Apr 26 19:27:05 _av500_: I read this morning that there _is_ a PSU in the box Apr 26 19:27:21 I was a bit surprised, so maybe the article was wrong... Apr 26 19:27:54 we live in times of clouds and virtualization ... it shops a virtual PSU Apr 26 19:28:00 <_av500_> http://www.adafruit.com/products/1278#Description Apr 26 19:28:06 <_av500_> says no psu Apr 26 19:28:34 hmm... where'd I see that link... Apr 26 19:29:14 http://arstechnica.com/information-technology/2013/04/for-your-robot-building-needs-the-45-beaglebone-linux-pc-goes-on-sale/ Apr 26 19:29:45 that has passed through the online-journalist blur filter Apr 26 19:29:47 ^^ "Although BeagleBone Black costs $10 more than a Raspberry Pi, it comes with a power supply and network cable whereas the Pi does not" Apr 26 19:30:57 I can neither confirm nor deny, and yes, one can't believe everything they read online, etc. Apr 26 19:31:21 the actual seller websites tend to be _slightly_ more accurate Apr 26 19:31:30 I would concur Apr 26 19:32:50 but even they sometimes tell lies Apr 26 19:33:27 like this one I came across recently: http://www.scan.co.uk/products/1gb-gainward-g-210-passive-1000mhz-gddr3-gpu-589mhz-8-cores-d-sub-dl-dvi-i-hdmi-low-profile Apr 26 19:33:45 the description claims "single slot" Apr 26 19:33:58 the image shows a heatsink clearly about twice that width Apr 26 19:34:20 hmm yeah Apr 26 19:34:57 manufacturer website lists physical dimensions in violation of the single-slot theory Apr 26 19:39:25 I don't understand why it's so hard to find a single-slot graphics card Apr 26 19:39:58 Does the black have the same headers and spacing as the beaglebone? Apr 26 19:41:04 shapr: yeah minus the PMIC Apr 26 19:41:19 mru: they're out there; they just have fans that get loud. I'm pretty sure I'm running one right now, but I can't even remember what the gpu is at this point. I'd have said 44x, but maybe that was the old one.... Apr 26 19:41:20 Does that mean adafruit's proto cape will still work correctly? Apr 26 19:41:28 yeah Apr 26 19:41:48 alan_o: I have one in my pc too, but I need to replace it Apr 26 19:41:52 I found one eventually Apr 26 19:41:56 single-slot fanless Apr 26 19:42:52 nice. I'd like to get fanless everything, but whenever I'm buying PC parts, it's "oh, that little fan won't make too much noise, and I'm tired of looking for parts and want to be done already" Apr 26 19:43:04 little fan, big noise Apr 26 19:43:17 _av500_: hopefully later today Apr 26 19:43:38 I have fanless graphics, fanless psu, and water-cooled cpu/chipset Apr 26 19:43:54 there's a 240mm fan on the radiator Apr 26 19:44:04 fine Apr 26 19:44:05 I always buy graphics cards that aren't cutting edge, so the hope is that they don't run so hot. I've been somewhat happy with the fans. Apr 26 19:44:07 not audible Apr 26 19:44:09 That's a big dang fan Apr 26 19:44:41 that's how it can turn at a leasurely pace and still get enough airflow Apr 26 19:44:55 the hard drives are the loudest parts of that machine Apr 26 19:45:12 need some ssd :) Apr 26 19:45:26 a few TB of ssd is pricey Apr 26 19:45:36 then you'll hear the 60 (50) Hz hum of the PSU Apr 26 19:46:01 finding a fanless psu was not easy at all Apr 26 19:46:10 there are many that _say_ fanless Apr 26 19:46:20 then if you read the fine print they fess up to having one anyway Apr 26 19:46:21 "it's not a fan, it's a blower" Apr 26 19:47:03 it seems like most of the pc parts market is targeting gamers Apr 26 19:47:25 the sort that want dual monster gpus and 1200W psu Apr 26 19:47:52 I saw something years ago about a guy who filled a fish tank with mineral oil and built a submerged PC in there. Ran good until the oil seeped into the capacitors, so they said. Apr 26 19:48:02 heh Apr 26 19:48:31 yeah, stuff made for the "enthusiast" market has a different definition of enthusiast than we fit into. Apr 26 19:50:25 now it's just a fan in my tv that's bugging me Apr 26 19:50:46 it's one of those little whiny things Apr 26 19:51:06 Oh, the mineral oil PCs seem cool in theory Apr 26 19:51:10 a fan in the TV - bogus. Apr 26 19:51:12 there have been many instances of people doing this Apr 26 19:51:24 http://www.pugetsystems.com/submerged.php Apr 26 19:51:29 I heard about another guy who had mineral oil seep up the cables of some of his peripherals Apr 26 19:51:45 mru: you need to hack your TV - put in a bigger, slower fan. Use lots of duct tape. Apr 26 19:52:03 emeb: I've contemplated some kind of surgery Apr 26 19:52:28 but then again, this thing is ripe for replacement soon anyway Apr 26 19:52:33 Also, of the viscosity of the oil killing fans over time Apr 26 19:52:55 fans meant for air don't fare too well with liquids Apr 26 19:52:58 mru: I've done that on several of my little servers - pulled out the small fast fans that came in it from the mfg and put in big slow ones. Apr 26 19:53:13 oh, I've done that on more than one machine in the past Apr 26 19:53:50 the alphas were tricky Apr 26 19:54:02 had to build an adaptor circuit for the rotation sensor Apr 26 19:54:04 But getting a new TV sounds like a better idea - one w/o fan. Apr 26 19:54:25 I'm waiting for the 3D craze to go away properly Apr 26 19:54:35 hopefully then they'll improve something that actually matters Apr 26 19:55:31 but then how will you have desktop effects!! Apr 26 19:55:48 captchas make me feel stupid :( Apr 26 19:55:56 BBone Black in stock http://www.adafruit.com/products/1278 going fast :/ Apr 26 19:56:01 alan_o: on the tv? Apr 26 19:56:02 do boost libraries have to be recomplied after a kernel upgrade? Apr 26 19:56:08 PRU_EVTOUT_2: ugh, me too. It's way too hard most of the time. Apr 26 19:56:15 PRU_EVTOUT_2: no Apr 26 19:56:26 kernel doesn't change abi Apr 26 19:56:40 you can run binaries from 1995 if you so please Apr 26 19:56:45 mru: oh, maybe not on the tv.... Apr 26 19:58:13 not that I use "effects" anywhere Apr 26 19:58:55 down from 55 to 32 :/ Apr 26 20:00:16 mru: I think part of the thing with me for fans, is that as quiet as I make everything, I still will have to listen to the air conditioner most of the year Apr 26 20:00:25 shadyman, dude, thanks! Apr 26 20:00:41 PRU_EVTOUT_2: better hurry :/ Apr 26 20:00:45 already done! :D Apr 26 20:00:51 k Apr 26 20:01:00 alan_o: then your aircon is too noisy Apr 26 20:01:05 you can just keep refreshing the product page to watch'em disappear :3 Apr 26 20:01:09 i could be an ass and order more, but i can live with the 7 week lead time from mouser before i do a bulk :) Apr 26 20:01:16 maybe you can submerge the entire house in oil Apr 26 20:03:18 so, how does that work? Apr 26 20:04:03 we were talking about cooling computers in that manner Apr 26 20:07:05 apparently digikey has some on order too Apr 26 20:11:23 thanks mru! (not sure if you got the message) Apr 26 20:12:38 PRU_EVTOUT_2: If you're going to do bulk, go to CircuitCo directly Apr 26 20:13:43 PRU_EVTOUT_2: That's what they ask people to do, and you'll pay less per unit iiuc. Apr 26 20:24:12 Hello, what is the ethernet speed on the beaglebone black? Apr 26 20:24:20 100 Apr 26 20:24:28 Thank you Apr 26 20:25:06 did I read right in TI's sitara literature that it is capable of Gig-E? obviously the PHY would need to be different but just curious Apr 26 20:25:17 yes Apr 26 20:26:23 that is pretty cool. not sure how useful it is for a small board like that but still... Apr 26 20:26:24 hi ynezz Apr 26 20:41:33 Spirilis: 100Base-T is less than 12 megabytes per second, so maybe, if you had some heavy sensors. Apr 26 20:53:02 doh. forgot to set temp dir on opkg upgrade to something besides /tmp. beagleborken. Apr 26 21:06:45 what is a good kernel for the bb-xm these days? Apr 26 21:06:50 3.2 from meta-ti Apr 26 21:06:54 ? Apr 26 21:07:03 mainline? Apr 26 21:07:17 mine's running some hacked up 3.0 Apr 26 21:20:39 mru: retro Apr 26 21:20:55 1GHz retro Apr 26 21:34:40 I am trying to boot v3.9-rc5 on bbone and I get nothing. Checkout my log https://gist.github.com/witkamp/ea3872cb4c78bb210933 Apr 26 21:35:18 I might be missing some thing with the fdt Apr 26 21:38:38 mourning Apr 26 21:38:52 1 jiggahurtz, awesome Apr 26 21:39:06 evebling, ka6sox-farfarawa Apr 26 21:39:08 ka6sox-farfarawa: what part of the world are we today Apr 26 21:39:08 ? Apr 26 21:39:19 mmm...jiggahurtz! Apr 26 21:39:43 the smoldering remains of LA Apr 26 21:39:54 lots of banging of bitz with a full jiggahurtz Apr 26 21:39:55 witkamp: try enabling earlyprintk (DEBUG_LL) for it Apr 26 21:40:38 Hey! Any google summer of code mentors about? Apr 26 21:40:52 tsquar3d: maybe? Apr 26 21:41:03 lol maybe? Apr 26 21:41:23 depends on what questions you have...ask away! Apr 26 21:42:35 :-p Apr 26 21:43:09 (if its about a specific idea the mentor might not be here now) Apr 26 21:43:09 So, I have an idea for a gsoc project - I am currently a MPhil student transferring into a PhD program and I will be studying data visualization.. Apr 26 21:43:47 Well, I would like to use a beagleboard as a data collection platform and interface it with a 3D game engine to visualize the data collected. Apr 26 21:43:48 :-) Apr 26 21:44:31 which game engine? Apr 26 21:44:44 ka6sox-farfarawa: The Blender Game Engine. :-) Apr 26 21:45:06 I have been using it for the last 2 years for building simulations. Apr 26 21:45:29 It's open source, of course. :-) Apr 26 21:46:16 do you plan on having the Beagle do the display work as well as data collection? Apr 26 21:46:56 ka6sox-farfarawa: That would be optimal -- but we'd have to see what the capacity to do both at once is -- it'd be part of the project to explore this possibility. :-) Apr 26 21:47:34 how would this benefit the Beagle Community and the larger Open Source Community? Apr 26 21:51:26 Turl: Still the same. Apr 26 21:52:25 tsquar3d: ^^ Apr 26 21:52:34 ka6sox-farfarawa: I see benefits..it's intriguing Apr 26 21:53:00 Ah. Great question. Well, scientific vizualization is really picking up in terms as an academic field in of its own -- and becoming a booming industry (look at how much National Instruments takes in!). At this stage, we really need an open source approach to this -- Apr 26 21:53:14 mdp: I'm not being contrary...just asking because thats on the proposal form. Apr 26 21:53:21 Before (if it is not already too late) this whole field is totally privatized. Apr 26 21:53:53 ka6sox-farfarawa: yep, understood..just caught my attention ;) Apr 26 21:54:09 yup, I see the possibilities too... Apr 26 21:54:51 Of course, if you get beagleboard out there associated NOW as a scientific data collection and visualization tool -- and hey it does some other awesome stuff too -- you can get that audience looking towards beagleboard while they are still looking. :-) Apr 26 21:55:26 I'm just not sure how much is collection vs analysis and viz. Apr 26 21:55:48 tsquar3d: do you foresee problems working with the mostly binary blob SGX GPU and this FOSS visualization work? Apr 26 21:56:06 ka6sox-farfarawa: That's a complicated question in of itself -- it depends on the sort of data you are taking, etc. :-) Apr 26 21:57:26 mdp: Well -- the biggest problem I worry about is if the beagleboard really has the capacity to run 3D viz software... Apr 26 21:59:02 tsquar3d: as ka6sox-farfarawa is implying, one critical aspect to this is to start with a concrete problem you are trying to solve. going a step further, I suggest picking a specific type of scientific data to collect, think about what kind of analysis is necessary to transform it to visual data, and consider what type of data gains value by this real-time visualization technology. Apr 26 22:00:03 clearly you aren't going to choose ambient outdoor temperature, for example. Apr 26 22:00:10 I suspect you have some ideas already Apr 26 22:00:52 mdp: Oh, I certainly agree with you there -- that step in data visualization is pretty key. Apr 26 22:00:59 I do have some ideas, yes. :-) Apr 26 22:01:37 The question is what sort of technology I will have access to. Apr 26 22:01:55 tsquar3d: fwiw, I can't begin to speculate on SGX/A8-1GHz/Blender … however, I would suggest some research on it running any common "demo" on a comparable embedded platform Apr 26 22:02:26 tsquar3d: playing devils advocate somewhat, i don't see the point in using a beaglebone for a rendering since it is so limited. there's most likely a device (smartphone, desktop, laptop, or tablet) with much better graphics power. Apr 26 22:02:31 mdp: I would propose that be part of the GSoC project, perhaps? Exploring the cpacity. Apr 26 22:02:34 there should be a number of people doing Blender on other ARM boards..dunno if we have anybody here Apr 26 22:03:10 PRU_EVTOUT_2: one issue with phones is the limited ability to move data into them Apr 26 22:03:34 PRU_EVTOUT_2: Right, and that's something I'd like to test out... there is certainly other software out there -- and perhaps even writing my own custom openGL project. Apr 26 22:03:36 in fact, PRU_EVTOUT_2, I found myself nodding my head to that exact point that was made on this week's Amp Hour podcast Apr 26 22:04:16 PRU_EVTOUT_2: phones/tablets are great for lower bandwith / high latency types of data Apr 26 22:04:17 mdp: wifi is fast. :) Apr 26 22:04:37 wifi is not fast to me ;) Apr 26 22:04:39 mdp: Right, but I'd like to, if possible, cut out any extra technology. Apr 26 22:04:53 wifi is flaky and unreliable if other stuff is around Apr 26 22:05:00 That's what makes beaglebone, to me, better for this than arduino -- because you need a computer attached. Apr 26 22:05:00 :-/ Apr 26 22:05:04 i'm not too familiar with visualization, but i always assumed visualization was low latency, considering our brains can't really process wiggling graphs ;) Apr 26 22:05:18 wifi is nice for things you put in your pocket Apr 26 22:05:59 PRU_EVTOUT_2: It seriously depends on the type of visualization -- that's actually going to be part of my PhD work is working out what is the best way to represent specific types of data. Apr 26 22:06:12 so, my point is that there are many use cases where you want a device that interacts with real world (analog sensors) with a high data rate..and provides a UI to reflect the data collection Apr 26 22:06:23 all on one device Apr 26 22:06:35 Some systems are best visualized in 3d space -- some it two. Apr 26 22:06:52 mdp: Exactly -- hence beagleboard. Apr 26 22:07:23 mdp: ^^^ Apr 26 22:07:32 right Apr 26 22:07:39 mdp: I have one of those, I call it a 'brain' Apr 26 22:08:06 just got my BBB, looks nice Apr 26 22:08:09 so as an example…many folks here are probably aware of the hobbyist grade android oscope project. Apr 26 22:08:11 I've looked at other platforms -- they are either way to expensive or don't have the capability. Apr 26 22:08:33 Yep. Have checked that beast out. Apr 26 22:08:34 :-)_ Apr 26 22:08:40 how do I use JTAG on BBB? Apr 26 22:08:51 are there any good benchmarks for the accelerator? i don't see any with a lazy google search. Apr 26 22:09:07 but you simply aren't going to have something like a high-end unit using your android phone as a display Apr 26 22:09:26 who knows, maybe it could render a 10,000 point cloud at 200fps! Apr 26 22:09:40 snaiil: solder a cTI jtag connector on it Apr 26 22:09:43 * ka6sox-farfarawa isn't sure waht PRU_EVTOUT_2 is smoking... Apr 26 22:09:50 lol Apr 26 22:10:03 Either way -- we won't know if this could work unless we test it. Apr 26 22:10:22 So-- I guess if there aren't any more advocating of the devil -- what do you think? Apr 26 22:10:43 ka6sox-farfarawa: i hope you're joking! Apr 26 22:10:49 yes, as we say around here… http://26-26-54.hardwarebug.org/30 Apr 26 22:13:25 tsquar3d: so back to ka6sox-farfarawa's question…how would you answer the question on the gsoc application? what is the benefit to the community of this project? Apr 26 22:14:08 *rereads tsquar3d brief answer to that question. Apr 26 22:14:08 consider that the key to being approved is often clearly articulating the benefits…the final approver doesn't always grok the big picture Apr 26 22:15:31 The concise answer -- getting scientists into your user base before they all start using raspberry pi for this :-p Apr 26 22:16:05 lol Apr 26 22:16:19 that's probably all jkridner needs to hear too :) Apr 26 22:16:32 Seriously... that's the plain truth. Apr 26 22:16:42 ok, my turn to drive on our long weekend…cya all tuesday. Apr 26 22:17:00 tsquar3d: I get it. work on expanding it is my suggestion Apr 26 22:17:07 the ideal is sound, I think Apr 26 22:17:13 bbt Apr 26 22:17:44 Thanks, mdp Apr 26 22:18:10 long weekend? lucky you :) Apr 26 22:19:03 So -- does this pique anyone else's interest? I think part of the key in all this is to get a mentor that would be willing to support the application -- no? Apr 26 22:20:27 si Apr 26 22:20:50 So.. ka6sox-farfarawa are you a mentor? Apr 26 22:20:57 witkamp: did you add earlyprintk to the cmdline? Apr 26 22:21:13 I have been asked to be a mentor for GSoC this year. Apr 26 22:21:20 Turl: yep Apr 26 22:21:35 Cool, ka6sox-farfarawa, what do you think? Apr 26 22:21:36 I also verified the konfig Apr 26 22:22:06 Turl: added "debug earlyprintk" to the cmdline Apr 26 22:22:23 witkamp: does something older work with the same uboot & company config? Apr 26 22:22:25 say, 3.8 Apr 26 22:22:42 yes v3.2.6 Apr 26 22:23:00 witkamp: try with 3.8 Apr 26 22:24:27 tsquar3d: it does sound interesting...I'd like to see this fleshed out a bit more Apr 26 22:24:48 ka6sox-farfarawa: Well, that's the idea of the application. ;-p Apr 26 22:25:31 I'm saying start the process and ask questions either here or in #beagle-gsoc Apr 26 22:25:54 I did not realize there was a gsoc board. Apr 26 22:26:13 Err.. channel. Apr 26 22:26:22 * tsquar3d needs to get off the image boards. Apr 26 22:26:33 removed the fdt param on bootm and it boots now Apr 26 22:26:57 not sure if I understood your idea fully, but maybe this is useful to get ideas http://www.cnx-software.com/2013/02/08/headless-connected-oscilloscope-based-on-cubieboard-or-beaglebone/ Apr 26 22:27:04 tsquar3d: ^ Apr 26 22:28:08 Thanks, Turl, the gist of it is -- I want to turn the beagleboard into an all-in-one data collection and analysis machine. :-) Apr 26 22:28:23 -- preferrably using 3d graphics. Apr 26 22:28:44 what kind of data? Apr 26 22:28:50 bits Apr 26 22:28:53 a voting machine would fit that description :) Apr 26 22:28:53 Turl: Any kind. Apr 26 22:28:56 mru: :-) Apr 26 22:29:02 mru: so funny ;) Apr 26 22:29:27 See, my BSc is in physics -- and we used NI's rediculously overpriced and closed software / hardware. Apr 26 22:29:47 but labview is fun! Apr 26 22:30:15 PRU_EVTOUT_2: heh :) Apr 26 22:30:17 PRU_EVTOUT_2: :-| Apr 26 22:30:26 * tsquar3d is not amused. Apr 26 22:31:45 the thing is, the amount of amusement remains constant Apr 26 22:31:59 so for some of us to be amused, it must be at someone else's expense Apr 26 22:32:33 I am saying get a prototype out there before another project does *cough -- raspberry pi -- hack* Apr 26 22:32:39 mru: are you saying every time i laugh, someone suffers? Apr 26 22:32:40 entropy must be incremented, or amusement stops Apr 26 22:32:59 Does a uImage-dtb.am335x-bone still take a dtb as in the 3rd reg on boot? Apr 26 22:33:20 witkamp: that naming suggests it's a zImage with appended dtb Apr 26 22:33:26 inside of an uImage Apr 26 22:33:35 i can't picture pi being used for somtething like this. Apr 26 22:33:38 so it wouldn't take a dtb Apr 26 22:33:47 (an external one, that is) Apr 26 22:33:47 I can't picture pi being used Apr 26 22:33:50 PRU_EVTOUT_2: You can't, but others might. Apr 26 22:33:59 so it takes the ATAGS? Apr 26 22:34:08 It's the buzz word ATM. Apr 26 22:34:26 Particularily over here in the UK. Apr 26 22:34:29 they need some humble Pi Apr 26 22:34:48 witkamp: can you paste the boot log? Apr 26 22:34:58 witkamp: it should say if it's using DT or not Apr 26 22:35:01 i remember back when nerds couldn't be swayed by buzzwords, only by specs! Apr 26 22:35:16 witkamp: appended dtb is a hack for those bootloaders that are not dt-aware Apr 26 22:35:24 ka6sox-farfarawa: And that's what I think this project could use -- serious applications, which RPI has few. Apr 26 22:35:30 PRU_EVTOUT_2: those are not proper nerds Apr 26 22:35:37 PRU_EVTOUT_2: Yes, but administrators are uni's LOVE them. Apr 26 22:35:44 I heard rpis are great xbmc boxes Apr 26 22:35:46 they are the embedded equivalent of script kiddies Apr 26 22:35:51 Turl: that's not true Apr 26 22:35:53 And they are the ones with their hands on the purse strings. Apr 26 22:36:04 Turl: they actually struggle quite a bit Apr 26 22:36:25 and I've seen the hdmi output crap out with some tvs Apr 26 22:36:30 Admins LOVE buzz words -- they LOVE simple answers -- and they hold the wallets. Apr 26 22:36:31 mru: I've seen people buying rpis to run xbmc on them :| Apr 26 22:36:48 mru: for everything else there's better alternatives Apr 26 22:36:54 <_av500_> about the only use case for them Apr 26 22:37:00 and it can't even do that Apr 26 22:37:09 Turl: i've seen people buy mouthwash to get drunk. doesn't mean it's a good idea. Apr 26 22:37:41 PRU_EVTOUT_2: well, it was people that usually complain of all the things, I figured it ran okay Apr 26 22:38:02 I suppose they didn't have an lg tv then Apr 26 22:38:44 Oh.. and, by the way -- http://www.raspberrypi.org/phpBB3/viewtopic.php?f=45&t=35887 Apr 26 22:38:52 They already are getting a head start. Apr 26 22:39:12 it's ok, it's on kickstarter Apr 26 22:39:14 is this an ARM race? Apr 26 22:39:18 there's no way that'll work Apr 26 22:39:24 No, it failed.. Apr 26 22:39:32 But the point is, someone has already thought of it. Apr 26 22:39:36 kickstarter projects have an amazingly high failure rate Apr 26 22:39:45 <_av500_> crapstarter.org Apr 26 22:40:19 So, yeah.. we have to beat them to it, guys. :-) Apr 26 22:41:28 _av500_: you had my hopes so high. i thought it would be a page of all the stupid kickstarter ideas. Apr 26 22:41:49 PRU_EVTOUT_2: there's already one for that Apr 26 22:41:53 kickstarter.org Apr 26 22:41:55 <_av500_> PRU_EVTOUT_2: I wanted to get that kickstarter Apr 26 22:42:03 <_av500_> kickstarted Apr 26 22:42:06 <_av500_> but they refused Apr 26 22:42:20 shame Apr 26 22:42:29 we need a replacement for regretsy Apr 26 22:42:44 Turl: It appears the hack works. Apr 26 22:42:50 kickstarter sounds like an awesome way to make a buck Apr 26 22:42:59 So? Any feedback? Good GSoC idea? Apr 26 22:43:19 Turl: In my desperation I added the dt to the image Apr 26 22:43:54 tsquar3d: so wait, do you want to make a somewhat general purpose type data aq unit? Apr 26 22:44:03 with nice visualization built in? Apr 26 22:44:26 PRU_EVTOUT_2: That's the idea. :-) Apr 26 22:44:45 for some reason i was thinking you wanted to use it more of a middle man, with data coming in from other systems Apr 26 22:44:54 Oh... no! Apr 26 22:44:57 No no.. Apr 26 22:44:58 <_av500_> a meta data cape Apr 26 22:45:08 The whole 9-yards! Apr 26 22:45:19 <_av500_> 4rth base? Apr 26 22:45:22 <_av500_> -r Apr 26 22:45:25 9-yards of beaglebone? so like a beowolf cluster of them? Apr 26 22:45:41 *beowulf Apr 26 22:46:02 <_av500_> that's old: http://www.flickr.com/photos/av500/5125778540/ Apr 26 22:46:08 ... and if this is successful, it would be a long-term project as I need a platform to base my PhD around ;-) Apr 26 22:46:26 beaglewolf Apr 26 22:47:26 heh Apr 26 22:47:51 I'd like to see one Apr 26 22:48:11 there's also the beaglewall Apr 26 22:48:27 * jkridner|work still wants to see the blackwall Apr 26 22:48:30 <_av500_> but is there a king beyond the beaglewall? Apr 26 22:48:39 <_av500_> jkridner|work: ha, you are back Apr 26 22:48:46 sorta, kinda. Apr 26 22:48:51 <_av500_> jkridner|work: there's kinda Gsoc to take care abouts Apr 26 22:48:54 still in SJC, but managed to log in. Apr 26 22:48:56 <_av500_> just sayin Apr 26 22:48:59 yeah... Apr 26 22:49:04 this weekend is all GSoC. Apr 26 22:49:09 gotta catch up on it. :( Apr 26 22:49:13 <_av500_> okie Apr 26 22:49:25 PRU_EVTOUT_2: So, what say you? Apr 26 22:49:34 jkridner|work: I'd love to build a blackwall Apr 26 22:49:43 gonna work on a blog post and some cries out for more students today, hopefully, once I get through the e-mails on GSoC. Apr 26 22:49:44 <_av500_> in blackpool? Apr 26 22:49:58 mru: I can donate the Blacks. Apr 26 22:50:11 <_av500_> the coloreds Apr 26 22:50:11 sounds like a great idea that you could probably even make money with. but my words aren't worth much :) Apr 26 22:50:13 <_av500_> please Apr 26 22:50:17 I assume 7, using 1 for audio. Apr 26 22:50:26 jkridner|work: on a plane now? Apr 26 22:50:27 <_av500_> cool, send me 7 too Apr 26 22:50:35 <_av500_> I still have the 6 monitors Apr 26 22:50:38 oh, you want audio too Apr 26 22:50:39 <_av500_> 1280x1024 ok? Apr 26 22:50:40 no, actually in SJC. I fly out in the morning. Apr 26 22:50:41 tsquar3d: ^ was for you. Apr 26 22:50:51 ah... enjoying the Friday sessions? :D Apr 26 22:50:58 <_av500_> mru: we shall make the wall rise again Apr 26 22:51:03 PRU_EVTOUT_2: Thanks! So, do you know of any mentors around here that can get behind it? Apr 26 22:51:09 anyway, I'd have to work up my motivation considerably for anything to actually happen Apr 26 22:51:13 _av500_: k, but you have to make sure mru writes the code! Apr 26 22:51:19 <_av500_> of course Apr 26 22:51:26 this web client on beagleboard.org sucks. Apr 26 22:51:35 <_av500_> use a real client Apr 26 22:51:39 <_av500_> or upgrade your IE6 Apr 26 22:51:47 my employer is quite adept at sucking all my motivation for work _and_ side projects dry Apr 26 22:51:58 <_av500_> tsquar3d: for gsoc, see the beagle-gsoc ML Apr 26 22:52:02 mru: mass suckage Apr 26 22:52:07 <_av500_> and/oe #beagle-gsoc Apr 26 22:52:10 <_av500_> and/or Apr 26 22:52:14 Thanks av500 Apr 26 22:52:21 <_av500_> or ask me, but not now Apr 26 22:52:25 <_av500_> I need to sleep Apr 26 22:56:26 witkamp: hm, if you look at the kernel load address, it seems to be too near the dt blob, even overwriting part of it Apr 26 22:56:34 hates me, it does Apr 26 22:58:33 Oh... also.. Texas Instruments FTW. Apr 26 22:59:18 they should lower the price on the calculators Apr 26 22:59:24 tsquar3d_: always helps Apr 26 22:59:30 :-p Apr 26 23:00:00 Turl: notice u-boot relocates it line 44 Apr 26 23:00:02 ka6sox-farfarawa: I'll be sure to conclude my applicationj with that. Apr 26 23:00:03 :-) Apr 26 23:00:37 witkamp: yeah, after relocating the kernel Apr 26 23:00:52 http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&N=-1&isNodeId=1&Description=ti-83&x=0&y=0 Apr 26 23:01:12 you can buy a couple of BBBs with the money a calculator costs :P Apr 26 23:01:42 how did you think ti made their money? Apr 26 23:01:51 it's all calculators and level shifters Apr 26 23:02:50 Turl: "Booting kernel from Legacy Image at 81000000 ." line 32. Does this mean u-boot does not think it's DT compat? Apr 26 23:03:10 "Legacy Image" == uImage as far as I know Apr 26 23:03:18 K Apr 26 23:03:20 <_av500_> tsquar3d_: wow, you were in beagle-gsoc for long Apr 26 23:03:23 they have some new format called FIT iirc nowadays Apr 26 23:03:27 <_av500_> tsquar3d_: subscribe to the mailing list Apr 26 23:03:33 <_av500_> and write a pitch email Apr 26 23:03:54 av500: Yeah... should do. Apr 26 23:03:59 <_av500_> tsquar3d_: BUT Apr 26 23:04:04 <_av500_> GSoC is about SW Apr 26 23:04:12 <_av500_> so making HW is not really fitting Apr 26 23:04:18 Turl: I still am not seeing the overlap issue you raised. Apr 26 23:04:26 <_av500_> but now I need a nap Apr 26 23:04:27 asion: I don't want to make HW. Apr 26 23:04:29 witkamp: got the link again? I closed the tab :/ Apr 26 23:04:31 Wops Apr 26 23:04:40 <_av500_> okie Apr 26 23:04:43 woops* Apr 26 23:04:47 lol Apr 26 23:04:48 Turl: https://gist.github.com/witkamp/ea3872cb4c78bb210933 Apr 26 23:05:03 Load Address: 80008000 Apr 26 23:05:11 ## Flattened Device Tree blob at 80000000 Apr 26 23:05:12 _av500_: The hardware is already there. :-) Apr 26 23:05:15 <_av500_> ok Apr 26 23:05:18 <_av500_> thats good Apr 26 23:05:56 Turl: Is there a standard for the uImage load address? Apr 26 23:06:52 I think uboot relocates it if necessary, so I'd say no Apr 26 23:07:37 Turl: I don't think that is a problem the kernel is loaded by uboot to 0x81000000 Apr 26 23:08:15 Turl: uboot then moves the dt out of the way before entering uImage Apr 26 23:08:31 yeah Apr 26 23:08:37 but it moves the kernel first to 80008000 Apr 26 23:09:19 Turl: I'll check Apr 26 23:12:02 Turl: no difference https://gist.github.com/witkamp/ea3872cb4c78bb210933 Apr 26 23:12:42 Turl: thanks for your help I am going to call it a day. Apr 26 23:13:29 witkamp: do you have the log with appended dtb handy? Apr 27 00:19:23 oh goodie my copy of my background check is here :P Apr 27 00:24:45 just came across this, old news ? http://blogs.arm.com/embedded/938-playing-with-ds-5-ce-and-beaglebone-black Apr 27 00:36:25 hmm anyone have good literature to get me up to speed on the PRU? I just realized what it was... lol Apr 27 00:44:34 nm found https://github.com/beagleboard/am335x_pru_package Apr 27 00:45:02 yeah Apr 27 01:50:37 ok, so i ended up in the middle of something that maybe someone here can me help out with Apr 27 01:50:59 the BBB as sold by Element14 Apr 27 01:51:09 has a datasheet on their site Apr 27 01:51:26 and its Rev May 2012 Apr 27 01:51:45 and state the proc is 800Mhz Apr 27 01:51:57 datasheet for what? Apr 27 01:52:00 so some RPi ppl have taken that to mean BBB is lies Apr 27 01:52:12 and so my question is Apr 27 01:52:18 rpi people should be shot on sight Apr 27 01:52:37 is there a more recent datasheet that says the ARM SoC on BBB does indeed run at 1Ghz Apr 27 01:52:48 it _does_ run at 1GHz Apr 27 01:52:52 as they are wanting proof from my correction of their error Apr 27 01:52:58 *I* know that Apr 27 01:53:02 *You* know that Apr 27 01:53:09 but its an internet flamewar Apr 27 01:53:11 and they know they're full of shit Apr 27 01:53:19 mere facts won't shut them up Apr 27 01:54:01 there is also the claim that powering it over USB causes it to run at 600Mhz Apr 27 01:54:07 no idea where that came from Apr 27 01:54:15 but apparently the datasheet says that too Apr 27 01:54:57 even at 400MHz the bone would be faster than their silly little microcontroller Apr 27 01:56:26 crashovrd: https://github.com/CircuitCo/BeagleBone-Black/blob/master/BBB_SRM.pdf?raw=true "Sitara XAM3359AZCZ100, 1GHZ, processor." Apr 27 01:56:41 tyvm Apr 27 01:57:30 arm11 was exciting 10 years ago Apr 27 01:58:52 I asked the folks on the TI Microcontrollers facebook page, fwiw, they said it does run the 1GHz version and they just released that edition this month Apr 27 01:59:31 early datasheets tend to be conservative Apr 27 01:59:48 then once they see what the yields are, they decide on a final figure Apr 27 01:59:56 ah right Apr 27 01:59:57 makes sense Apr 27 02:00:19 some parts have speen bins too Apr 27 02:00:24 don't know if the am335x does Apr 27 02:00:39 *speed Apr 27 02:01:01 k, i found the revised http://www.ti.com/lit/ds/symlink/am3359.pdf Apr 27 02:06:42 omfg Apr 27 02:06:48 so i posted that Apr 27 02:06:59 and now the question is what is the actual clock on the BBB Apr 27 02:07:30 easy enough to measure Apr 27 02:07:30 this is just getting stupid and childish Apr 27 02:07:39 btw, im arguing with a broadcom guy Apr 27 02:07:43 where's this discussion taking place? Apr 27 02:07:56 im afraid to link it Apr 27 02:08:03 cuz it will just up the flamewar Apr 27 02:08:11 I'm not going to say anything Apr 27 02:08:31 irc, ph0rum, or what? Apr 27 02:08:39 http://www.raspberrypi.org/phpBB3/viewtopic.php?f=24&t=31844&start=50 Apr 27 02:08:45 last couple of posts Apr 27 02:12:06 k, i know its a single core Apr 27 02:12:14 but i have no idea wtf the actual clock is Apr 27 02:12:22 whether its 1Ghz or 999Mhz Apr 27 02:12:26 or something Apr 27 02:13:06 or 1001 Apr 27 02:15:40 hmm, "presuming the BBB is a single ARM core device" Apr 27 02:15:46 when he puts it that way, he's actually wrong Apr 27 02:15:54 there's the M3 for power sequencing too... Apr 27 02:16:00 so there are two arm cores Apr 27 02:16:05 at least Apr 27 02:16:16 possibly more that are not documented Apr 27 02:17:48 good point Apr 27 02:18:01 but that's splitting hairs Apr 27 02:18:06 no need for that Apr 27 02:18:38 the A8 is so much faster than the arm11 it's not even funny Apr 27 02:19:07 we were doing 720p video on the original beagle back in 2008 Apr 27 02:19:13 in software at 600MHz Apr 27 02:19:20 k, i edidted my response to include the PRU info Apr 27 02:20:10 ... i need new hobbies Apr 27 02:21:38 k! i have defended BBB's honor Apr 27 02:21:45 im from Texas so its a matter of pride Apr 27 02:21:47 :P Apr 27 02:25:34 what was that bit he said about it downclocking to 600MHz when powered by USB? sounds sketchy since the system ref. manual claims upwards of ~400-something mA power draw Apr 27 02:25:40 gonna assume that's false Apr 27 02:25:57 usb allows up to 500mA Apr 27 02:26:09 yeah Apr 27 02:26:13 pessimistically Apr 27 02:26:30 then power it by a charger and it's upwards of 2.1A (ipad/tablet charger) :-D Apr 27 02:26:35 why do you even care about the clock? Apr 27 02:26:47 some dude from another thread came up with that downclocking shit out of nowhere Apr 27 02:26:47 that other board uses crap that is a generation old Apr 27 02:26:54 yeah thought so Apr 27 02:27:20 I don't care, but wanted a quick fact check about that claim cause I also don't want my BBB running sub-par performance just because I chose a PC USB port for its power... Apr 27 02:27:20 so if I get a 10GHz 8086, is it going to be faster then a Pentium 4 @ 2GHz? Apr 27 02:27:49 definitely sounds like FUD from the intarwhebez. Apr 27 02:28:03 someone should look at the schematic and see if all the power is the same line Apr 27 02:28:14 i cant see them doing a sense Apr 27 02:28:15 stop abusing the PC USB port Apr 27 02:28:27 arm speed governors are software, not hardware Apr 27 02:28:35 well, controlled by soft Apr 27 02:28:50 they are obviously implemented in hardware Apr 27 02:32:41 for all we know, our entire universe is but a simulation in some elaborate software Apr 27 02:35:44 hmm for what it's worth, when powered by USB port, the VDD_5V pins aren't supplied, only the SYS_5V is Apr 27 02:36:01 need to plug in the barrel jack for the VDD_5V rail Apr 27 02:40:49 also fancy, the power mgmt IC can have its VDD_MPU rail voltage increased a bit to help assist higher clock speeds Apr 27 02:47:59 k, so if you plugit into usb to ur comp without the 5v barrel, it wont do anything Apr 27 02:48:12 is that the conclusion? Apr 27 02:48:34 it should work like normal just the VDD_5V pins on the expansion header won't be live I think Apr 27 02:49:01 k Apr 27 02:49:16 I think those are meant so capes can draw unlimited power from the 5V source without going through the power mgmt IC Apr 27 02:49:26 yes, im doing everything possible to not have to look at the schematics myself Apr 27 02:49:27 :P Apr 27 02:49:55 naturally this means if you're going through USB they're trying to make sure such capes won't run and exceed the USB port's draw / crash the system Apr 27 02:51:01 btw, this is the thread that originated the rumors/allegations Apr 27 02:51:02 http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=41489 Apr 27 02:51:21 Warning: Flame Bait Apr 27 02:51:30 proceed at your own risk Apr 27 02:55:14 RTFM Apr 27 02:55:23 (all of them.) Apr 27 02:55:32 and compare them M by M Apr 27 02:55:53 oh wait... there is M for the other board.. Ooops... guess all you can do is speculate and guess Apr 27 02:55:58 this no M Apr 27 02:57:58 man that thread is insane Apr 27 02:58:07 it is. Apr 27 02:58:30 the fan biys completely neglect that the original beagle led the way beating down the dev board pricing Apr 27 02:58:31 i don't see how people get so emotionally attached to a "thing". Apr 27 02:58:50 the lack of reality based thinking is insane Apr 27 02:59:12 * Crofton|work has seen this in other areas also Apr 27 02:59:31 smartphones! **** ENDING LOGGING AT Sat Apr 27 02:59:58 2013
