**** BEGIN LOGGING AT Fri Apr 05 02:59:58 2013 Apr 05 03:16:00 hi guy , i am looking to purchase beaglebone board Apr 05 03:16:36 however it seem element14 have an export restriction on it . Can any one explain whats e issues about it ? Apr 05 03:18:04 bradfa, he's taking a NAS to demo for Linus, hoping he'll choose his solution. Apr 05 03:18:07 where are you? Apr 05 03:18:22 mdp, GLHF! Apr 05 03:18:48 slean, where *are* you? Apr 05 03:19:10 heh Apr 05 03:20:50 i am located in singapore Apr 05 03:22:48 * mdp hopes CCS is as good as everybody says. Apr 05 03:24:11 HE HE HE HE HE HE HE Apr 05 03:24:53 yes, I'm thrilled Apr 05 03:24:59 and on windows too Apr 05 03:25:47 Win8? Apr 05 03:25:51 7 Apr 05 03:26:04 bleh Apr 05 03:26:13 msp430-gcc so far is working fine Apr 05 03:27:12 I needed it to debug code in a synopsys sim Apr 05 03:27:25 I like msp430-gcc mspdebug as well Apr 05 03:29:17 have to tell it I trust stuff a lot to get things installed Apr 05 03:29:21 makes me cranky Apr 05 03:29:25 and I don't trust anything Apr 05 03:31:27 koen: chromium works much better than the other browsers. doesn't like to run as root though. had to 'su - xuser' Apr 05 03:31:41 er, 'xhost +; su - xuser;' Apr 05 03:33:39 koen: also about to test https://github.com/jadonk/kernel/tree/3.8-musb-cppi-20130404 Apr 05 03:56:45 ds2, you may not be surprised to find that the exact steps I was given do not work Apr 05 04:03:12 #exactsteps? Apr 05 04:04:04 on a wiki and a readme...what could go wrong? Apr 05 04:05:32 > Apr 05 04:05:40 steps? hehehe Apr 05 04:06:27 16bit ints are a bit annoying Apr 05 06:50:01 morning Apr 05 06:52:42 hi tsjsieb Apr 05 07:25:04 JIHAD! Apr 05 07:25:06 FRIDAY! Apr 05 07:26:55 hi koth Apr 05 07:27:30 koen: started off a build with this patch: https://github.com/jadonk/meta-texasinstruments/commit/28314e32f0b7099de33e8149ee2a9d936f271263 Apr 05 07:27:40 also, USB patches aren't working worth a darn Apr 05 07:27:50 getting kernel oops with my integration Apr 05 09:08:49 gm Apr 05 09:09:25 jo panto Apr 05 09:09:33 h woglinde Apr 05 09:10:22 moin panto Apr 05 09:10:23 *hi even Apr 05 09:10:27 hi KotH Apr 05 09:43:54 troll Apr 05 09:44:09 hi mru^troll Apr 05 09:44:13 *^W Apr 05 09:45:13 hey mru! how's the rain? Apr 05 10:07:02 as we all know, god is in the rain. Apr 05 10:08:17 i thought, you were god? Apr 05 10:08:51 i am one among a multitude of valid gods. Apr 05 10:08:58 only if you're a rain god Apr 05 10:09:09 rain god but not a trucker, odd Apr 05 10:09:16 panto: nah. Apr 05 10:10:27 panto: you obviously have not watched enough v-movies. Apr 05 10:12:11 * mrpackethead is a hobbit. Not good Apr 05 10:12:16 or a god Apr 05 10:12:43 boffin, bolger, proudfoot? ;) Apr 05 10:17:52 i'd guess a took Apr 05 10:56:59 KotH: interesting Apr 05 11:13:02 av500: ? Apr 05 11:14:18 mranostay_pdx, did Linus like your NAS? Apr 05 11:15:03 mdp, if you need help, join #exactsteps. It's a very helpful channel Apr 05 11:15:21 * bradfa goes to get coffee to insert into face Apr 05 11:41:28 av500 you now get a phone-watch on pearl too Apr 05 11:44:58 yes, but not android Apr 05 11:47:56 looks 'interesting' Apr 05 12:19:29 /var/run/media/$user begone :) Apr 05 12:20:18 ? Apr 05 12:20:35 did i miss news ? Apr 05 12:24:32 bradfa, thanks..I'm sure it's filled with CCS gurus ;) Apr 05 12:25:02 mdp, of course! :) Apr 05 12:25:17 mdp, I feel your pain, but at least I'm on Linux with CCS Apr 05 12:27:13 I'm told Linux with CCS is more painful than Windows Apr 05 12:27:25 due to lack of care from the developers Apr 05 12:27:27 ogra_: udev rule Apr 05 12:27:35 bradfa, that's a monday problem Apr 05 12:27:40 somebody had mercy and fixed udisks2 Apr 05 12:29:00 ah Apr 05 12:29:03 mdp, CCS on Wheezy acts differently than CCS on Squeeze for me Apr 05 12:29:15 so, yesh, CCS sucks big on modern-er Linux Apr 05 12:29:17 so its back to /media ? Apr 05 12:29:23 yes Apr 05 12:29:46 eventually we'll move away from TI chips so this problem will be short lived for me :) Apr 05 12:30:03 yay FHS ++ Apr 05 12:30:42 ogra_: ENV{ID_FS_USAGE}=="filesystem", ENV{UDISKS_FILESYSTEM_SHARED}="1" Apr 05 12:30:58 bradfa, it sounds more like you have a respiratory problem than anything else Apr 05 12:31:13 I'll remove that once that classroom full of british kids connects to my laptop.... Apr 05 12:31:13 bradfa, you can not escape TI chips...unpossible Apr 05 12:31:28 there is always a PMIC Apr 05 12:31:30 or a level shitter Apr 05 12:31:37 Apr 05 12:31:49 all your analogs are belong to us Apr 05 12:31:51 av500, happily, where we can move away from TI chips needs neither PMICs nor shitters Apr 05 12:32:25 does need radio transceiver, though, and chipcon's got the lowest price in town :( Apr 05 12:32:35 unless we remove that... Apr 05 12:32:39 bradfa: what chip is it then? Apr 05 12:32:44 cc430 now Apr 05 12:32:54 * mdp notes the new level shitter product line Apr 05 12:32:58 sounds messy Apr 05 12:33:08 mdp, link to errata? Apr 05 12:34:07 friday morning + lack of coffee + windows + git == developer asking me why his head is detached Apr 05 12:35:28 windows yes Apr 05 12:37:30 bradfa: no, I mean fior the MCU Apr 05 13:01:42 av500, CC430 is an MSP430 and CC1101 transceiver in one package Apr 05 13:03:32 ah Apr 05 13:46:59 bradfa: there is one with bluetooth in it too, isn't it? Apr 05 13:47:18 dm8tbr, possibly Apr 05 13:47:54 dm8tbr, there's a CC series with 2.4 GHz built in and you can get someone's proprietary 802.15.4 stack bundled on it Apr 05 13:48:08 our stuff is all < 1 GHz Apr 05 13:48:53 bradfa: CC2560 is probably what powers my Metawatch Apr 05 13:49:18 dm8tbr, some of the CC series have MSP430 cores while others have 8051 cores Apr 05 13:49:26 yup Apr 05 13:49:27 I'm not sure of the 8051 lines Apr 05 13:49:45 we're solely cc430 so far, we've steered clear of the 8051 parts Apr 05 13:50:03 would like to move to coretex-m0 and separate transceiver Apr 05 13:50:11 would be cheaper and use less stupid tools Apr 05 14:18:50 alan_o: it seems I get an interrupt everytime CS toggles Apr 05 14:19:06 hmm Apr 05 14:19:53 alan_o: do I need pullups on that line? Apr 05 14:19:54 mdp, jkridner: http://www.businessinsider.com/the-worlds-highest-paid-software-engineers-work-for-these-25-companies-2013-4?op=1 Apr 05 14:20:04 koen: you shouldn't need to pull anything. Apr 05 14:20:37 alan_o: after I load your dtbo the interrupt ping goes from 3.3V to ~0.8V Apr 05 14:20:37 solder bridge? Apr 05 14:21:06 hmm CS and INT aren't adjacent Apr 05 14:21:21 let me take a picture of the scope Apr 05 14:23:26 whoa, there's a deer in my backyard again. Apr 05 14:23:35 * jkridner updated devicetree overlay + capemgr example: https://github.com/jadonk/validation-scripts/blob/master/test-capemgr/README.md Apr 05 14:23:38 shoot it! Apr 05 14:24:14 * KotH wonders how many people at his company would kill him when he'd start using m4 as a preprocessor for C code Apr 05 14:24:50 Crofton|work: can't shoot it :( < 300 yards from a house, not in season, no license Apr 05 14:25:42 http://www.youtube.com/watch?v=iATzgXyhYRs Apr 05 14:26:00 That wouldn't stop the locals here :) Apr 05 14:26:15 Crofton|work: That guy is funny Apr 05 14:26:20 yeah Apr 05 14:26:59 Crofton|work: mom and dad had a tape of him back when I was a kid. Wernher von braun song. Apr 05 14:27:08 yep Apr 05 14:27:12 alan_o: salaries in the us seem a bit low to me... Apr 05 14:27:44 "I make ze rockets, but where the come down, that's not my department.... says Wernher von Braun" Apr 05 14:27:45 alan_o: an EE with uni degree and 1-2 year work experience gets here 90kchf/y avg Apr 05 14:27:57 and you have to pay for your own guns! Apr 05 14:28:10 alan_o: 120k/chf avg for 5-10y exp Apr 05 14:28:19 alan_o: software is usually 10-20% higher Apr 05 14:28:29 oh.... National Brotherhood Week. Those are the ones I remember the most.... Apr 05 14:28:52 Poisoning Pidgeons in the Park? Apr 05 14:28:57 KotH: we pay less taxes on that money Apr 05 14:29:09 and get more services :) Apr 05 14:29:14 alan_o: and less for food, rent, anything ;) Apr 05 14:29:34 alan_o: but at least i dont have to worry about unemployment or health care ;-> Apr 05 14:29:34 KotH: that comes from taxes. VAT raises the base cost of everything Apr 05 14:29:56 alan_o: we've only 8.5% VAT Apr 05 14:30:29 Thats what you see at the register. There's VAT that goes into every stage of manufacture, production, distribution, etc. Apr 05 14:30:47 alan_o: swiss philosophy is to make taxes as direct as possible. ie if streets need to be paid, then the cars are taxed, and not the water bottles Apr 05 14:30:52 All those VAT's are rolled into the price you see on the sticker. Hidden from you. Apr 05 14:31:27 KotH: I like the direct idea. People know what they're paying for and what they're getting. Apr 05 14:31:36 alan_o: exactly Apr 05 14:31:40 alan_o: that's the idea behind it Apr 05 14:32:10 alan_o: unfortunately a lot of infrastructure is paid trough a big pod and you have to ask to get the numbers for this pod Apr 05 14:32:28 Crofton|work: listening to "Pigeons" Apr 05 14:34:28 alan_o: http://dominion.thruhere.net/koen/images/mfr.png Apr 05 14:34:37 alan_o: top is INT, bottom CS Apr 05 14:38:48 M25us means 25us/div? Apr 05 14:39:35 I guess it must. Not sure what else it could mean. Apr 05 14:40:01 so your INT line spikes up really quick Apr 05 14:40:03 or down Apr 05 14:40:26 That whole picture hurts my head. Apr 05 14:41:19 because what you should see is INT go down, then INT go up, then /CS go down (while it reads the data from the SPI), then /CS go up (with no change in INT at the end) Apr 05 14:43:42 koen: both signals DC coupled? Apr 05 14:44:01 DC coupled according to my scope Apr 05 14:44:23 koen: that's weird... i would have expected one to go down... Apr 05 14:44:48 hmm.. maybe it's cross talk coupled with reflections Apr 05 14:46:20 koen: what's the steepnes of the CS rise/fall time? Apr 05 14:48:39 10ns/V Apr 05 14:48:49 rise Apr 05 14:49:13 that's pretty fast Apr 05 14:49:23 driven by an AM3xxx? Apr 05 14:49:38 yes Apr 05 14:49:41 SPI chipselect Apr 05 14:49:49 if so, put some 10-50R resistors in series at the AM Apr 05 14:50:06 that' will limit the rise time and dampen the reflections Apr 05 14:50:55 koen: are you seeing CS normally low? Apr 05 14:51:48 koen: the polarity of CS seems backward. Apr 05 14:52:34 alan_o: could very well be, did you send the correct dts file? Apr 05 14:52:42 It's the one I'm using Apr 05 14:52:42 or am I missing patches? Apr 05 14:53:01 no, I'm running with what I sent you (patched my tree with the same ones I sent) Apr 05 14:53:18 ok Apr 05 14:53:21 weird Apr 05 14:53:33 no chance you counted pins from the wrong side or anything? :) Apr 05 14:56:01 If you're anywhere near Rochester, NY, be on the lookout for red dye leaking into the sewer... or something... Kodak security message was hard to hear Apr 05 14:56:35 alan_o: http://www.flickr.com/photos/koenkooi/8621244349/in/photostream Apr 05 14:56:42 alan_o, yay, a good job hunting guide ;) Apr 05 14:58:06 * koen heads down for food Apr 05 14:58:09 mdp: is that pic of the calculator you work on? Apr 05 14:58:26 koen: what's that strange black board in the picture? Apr 05 14:59:55 lol! we are not the only ones who use capton tape for stuff where a cheap tape would do as well: http://www.flickr.com/photos/koenkooi/8053052041/in/photostream/ :-) Apr 05 15:02:09 KotH: indeed, it's the duct tape for EEs Apr 05 15:03:11 lol Apr 05 15:04:13 koen: but unlike duct tape, it's horribly expensive :) Apr 05 15:05:58 koen: it's hard to see where INT goes to, I think I counted to PIN 26 Apr 05 15:06:22 It's the right place... :( Apr 05 15:06:49 It also looks like the module is raised from the board below it Apr 05 15:06:59 touching those vias would be bad Apr 05 15:07:01 * koen paid attention to alan_o Apr 05 15:07:02 but you aren't doing that Apr 05 15:07:03 :) Apr 05 15:07:49 If you disconnect the INT line, but still look at it on the scope, same thing? Apr 05 15:08:14 I mean basically with INT not connected to the SoC Apr 05 15:09:05 ah Apr 05 15:09:13 that makes the CS go away Apr 05 15:09:30 You'd need to restart it Apr 05 15:09:44 there should be some CS's at the beginning (not driven by interrupt) Apr 05 15:10:05 * koen reboots Apr 05 15:10:26 could just run ./setup instead. Re-loads the driver Apr 05 15:13:27 You have the one ground going through the alligator clip. I don't trust my alligator clips Apr 05 15:15:30 actually... Apr 05 15:15:35 .take reset and wake off completely Apr 05 15:15:46 arrrgh Apr 05 15:15:47 sorry Apr 05 15:16:02 I don't have the DT set up for those :( Apr 05 15:16:21 WEll, at some point I thought I decided the default was fine Apr 05 15:16:48 but I don't remember now (on my cape I have the jumper headers installed, and right now I have those jumpers removed) Apr 05 15:22:49 for your fridayly enjoyments: http://uncyclopedia.wikia.com/wiki/UnNews:America,_others,_not_real_democracies Apr 05 15:23:05 KotH: America is not a democracy Apr 05 15:23:10 KotH: America is a Republic Apr 05 15:23:52 that's the way it was designed by the founders. People didn't start saying Democracy here until the 20s, so I've been told. Apr 05 15:24:09 alan_o: did you see the "uncyclopedia" in the url? :) Apr 05 15:24:34 alan_o: it's the wiki version of SA :) Apr 05 15:25:08 KotH: hah. I should have clicked the link :) Apr 05 15:25:20 KotH: it is a peeve of mine though, "democracy" Apr 05 15:27:08 mourning Apr 05 15:28:47 moin ka6sox Apr 05 15:30:12 hiya KotH whats happening today? Apr 05 15:38:08 jkridner, playing with those patches...fun fun! Apr 05 15:38:35 alan_o, USA is a democracy, look at all the blow-hards spewing forth their opinions on tv / internet / radio. Everyone hears them :) Apr 05 15:38:40 detheridge: do you know if HDMI audio will be integrated today? Apr 05 15:39:51 bradfa: just because people can talk doesn't make it a democracy. In a democracy, the citizens vote directly on issue. In a Republic, citizens vote for representatives which vote on direct issues. Apr 05 15:40:48 alan_o, you don't get (poorly) trolled much, do you? :) Apr 05 15:41:14 it *IS* friday after all Apr 05 15:41:23 bradfa: I guess not, hehe :) Apr 05 15:42:51 ah voting fot TSA again Apr 05 15:43:36 I suspect I'd get shot for referring to the Republic of America :) Apr 05 15:43:47 Dear Leader! Apr 05 15:44:09 isn't that Republik? Apr 05 15:44:15 Crofton|work, it's "The People's Republic of America" Apr 05 15:44:37 Crofton|work: only because "Republic" has been hijacked by countries which are not republics (Union of Soviet Socialist..., People's Republic..., etc). Apr 05 15:44:52 Sure Apr 05 15:45:07 I like the sound of the "People's Republic of America" Apr 05 15:45:21 I actually do too. Apr 05 15:45:28 corfton hehe yes sounds like Il Kim Un Apr 05 15:45:30 People's Federalist Republic of America Apr 05 15:45:46 we have the "Homeland" because Fatherland and Motherland had already been used Apr 05 15:46:22 People's Republic of United Federalist States of America Apr 05 15:46:35 (PRUFSA for short ) Apr 05 15:47:19 I love the Motherland statue: http://en.wikipedia.org/wiki/The_Motherland_Calls Apr 05 15:48:55 "the super-tall" <<< this language in a wikipedia article? Apr 05 15:50:20 alan_o, remove the first "of", just simply People's Republic United Federalist States of America Apr 05 15:50:30 rolls off the tongue better Apr 05 15:50:41 no Apr 05 15:55:39 ka6sox: as you can see, it's friday :) Apr 05 15:56:05 ka6sox: other than that: fighting crufty, hacked msp430 code and preparations for a loooooong weekend :) Apr 05 15:56:34 TGIF Apr 05 15:57:13 is musb *supposed* to work? Apr 05 15:59:01 (that wasn't a rhetorical question) Apr 05 16:03:18 ka6sox, define work Apr 05 16:05:22 lets start with building. Apr 05 16:06:24 he panto Apr 05 16:06:46 ka6sox, is it a big building? Apr 05 16:07:40 no there are just some patches I'm looking at is all. Apr 05 16:07:50 I think I see what happened...nm Apr 05 16:08:16 ka6sox musb? Apr 05 16:08:19 haha Apr 05 16:08:55 * ka6sox feels like he is in a bad film noir movie Apr 05 16:11:09 I bet the killer is musb Apr 05 16:12:18 there are a few...(some hidden in the shadows) Apr 05 16:25:39 boys! have a nice weekend! Apr 05 16:26:51 hi Apr 05 17:14:51 Before I start at my weekend I have one question. I use a BMP085 sensor. If I mount them I can cat temp. and pressure. The valueas are ok. But if I do an i2cdump to the sensor I only see the values for calibration. All values for tem. and pressure are 00. Do I forget something ? Apr 05 17:19:29 hello, how would I dump the memory of raw memory or cpu registers? I looked at dd command but it seems to only work for files? Apr 05 17:19:43 on arago linux Apr 05 17:20:22 sd--: devmem2 Apr 05 17:20:57 thanks! ill try that Apr 05 17:21:31 sd--: are you wanting physical memory locations or are you asking about the actual arm registers? Apr 05 17:22:01 both Apr 05 17:22:42 sd--: devmem2 will read physical memory locations Apr 05 17:22:51 sd--: why do you need to read the arm registers? Apr 05 17:23:45 actually maybe i dont need arm registers...I just need device registers for now..which should be in physical memory correct? Apr 05 17:24:29 sd--: correct Apr 05 17:25:09 sd--: http://www.elinux.org/Board_Bringup_Utilities Apr 05 17:47:15 devmem2 works very well thanks! ... is there a version that does an address range? If not I'll just write a script Apr 05 17:50:30 Where is the upstream linux kernel for the am355x ? Apr 05 17:52:06 heh Apr 05 17:52:29 witkamp: We're using this: https://github.com/beagleboard/kernel/tree/3.8 Apr 05 17:53:00 So repo of patches. Apr 05 17:53:07 witkamp: as to your question, ask your local TI Field Application Engineer when the am335x will be bootable by the mainline kernel. Apr 05 17:53:31 witkamp: a repo of patches, and a script to patch your kernel. Apr 05 17:53:37 I see, it's a sore point Apr 05 17:54:13 the link I sent you is maintained by koen, of CircuitCo Apr 05 17:55:07 And he does not publish his git repo he used for intergrating? Apr 05 17:55:09 and he does a great job of it. How TI can make a chip like the am33x and be mostly uninterested in mainline, yes, is a sore point to some Apr 05 17:55:33 witkamp: not sure what you mean Apr 05 17:55:37 that's the git repo Apr 05 17:55:49 clone it, run patch.sh Apr 05 17:55:58 it downloads a mainline kernel and patches it Apr 05 17:55:59 I get it, Apr 05 17:56:18 witkamp, there's a normal kernel repo too Apr 05 17:56:20 witkamp, it *is* the best kept repo of am335X patches. Apr 05 17:56:58 panto: where? Apr 05 17:57:16 Yeah, where?

Apr 05 17:59:22 launching lawyers now! Apr 05 17:59:44 EVTs Apr 05 18:02:44 panto, Thanks, checking it out now. Apr 05 18:03:38 take note to _not_ base any of your branches on it Apr 05 18:03:57 since it's force updated very often Apr 05 18:04:12 panto, I see it rebased daily Apr 05 18:04:23 panto, will do, Apr 05 18:04:35 panto, will do Apr 05 18:04:54 panto, will do. Apr 05 18:05:08 simon says jump off a bridge Apr 05 18:05:26 panto, will do :) Apr 05 18:10:10 ka6sox: I rebase it a few times a day Apr 05 18:16:43 When using OpenEmbedded, is there an "easy" way to get a more recent linux kernel than the default one shipped in meta-ti, 3.2 ? Apr 05 18:17:18 use the angstrom setupscripts, that gets your 3.8.5 Apr 05 18:19:02 koen, you mean that angstrom has a 3.8.5 bitbake recipe ? Apr 05 18:19:04 meta-ti also has 3.8.5... Apr 05 18:19:35 denix, even for the Beagleboard ? I couldnt find anyone that matched.. Apr 05 18:20:03 denix, or is beagleboard == ti33x ? Apr 05 18:20:30 that's beaglebone Apr 05 18:20:50 ah sorry Apr 05 18:20:57 forgot to say that it was for the beagleboard Apr 05 18:22:46 Guess i need to add a custom kernel recipe.. Apr 05 18:24:46 expanding compatible_machine in the linux-mainline_3.8.bb recipe in meta-beagleboard would also work Apr 05 18:24:55 kernel works on both Apr 05 18:25:20 exactly what koen says - mainline should work Apr 05 18:27:05 I didn't say mainline would work Apr 05 18:27:15 I said " the linux-mainline_3.8.bb recipe in meta-beagleboard" Apr 05 18:28:27 oh, there is a meta-beagleboard :-) Apr 05 18:28:30 thats good news Apr 05 18:28:42 [kernel] koenkooi pushed 1 new commit to 3.8: http://git.io/6MCuWQ Apr 05 18:28:42 kernel/3.8 c41a4f6 Koen Kooi: 3.8: update to 3.8.6... Apr 05 18:29:27 Hi BeagleGithub Apr 05 18:30:41 so then I should drop meta-ti... Apr 05 18:32:22 just use the angstrom setup-scripts, those do the right thing Apr 05 18:40:41 koen, ok.. why dont extend the compatible_machines in meta-beagleboard ? Apr 05 18:41:14 I was waiting for capemgr to get ported to beagleboard and ditch the huge boardfile Apr 05 18:42:08 aha Apr 05 19:52:59 I get a kernel crash on boot with the 3.8.5 kernel from meta-beagleboard, in omap3_control_save_context+0x7e/0x128.. am i missing something obvious ? Apr 05 19:53:15 Running on the Beagleboard that is Apr 05 19:54:03 g'night Apr 05 19:54:21 hmm.. ill try updating to the 3.8.6 kernel that popped up in git Apr 05 20:05:11 maybe the patches didnt get applied in my previous build.. Apr 05 20:14:47 koen, could I .bbappend the beagleboard to compatible_machines maybe ? Apr 05 21:13:24 the world is chaning Apr 05 21:13:37 i've just found one of my parts suppliers accepts bitcoin!! Apr 05 21:17:10 mrpackethead, I thought you meant 4chan with that statement. Apr 05 21:30:36 mrpackethead: I just saw this one this morning https://medium.com/money-banking/2b5ef79482cb Apr 05 21:35:11 <_av500_> ahoi Apr 05 21:36:54 ahoi in deed. Apr 05 21:45:47 i have just started with first Beagleboard. loaded an SD card with an Angstrom build from Narcisus. have it only attached to the serial port of an Ubuntu laptop to monitor. Get the login, but after a few minutes get an error and the system locks up. Apr 05 21:47:15 I have a log of the event as well. Apr 05 21:47:44 I also had a usb keyboard plugged in and an ethernet cable, but it does the same thing regardless. Apr 05 21:48:23 I should say it did the same thing even when only the serial connection was there, but the log I have has the network and keyboard connected. Apr 05 21:56:51 how are you powering it? Apr 05 21:57:42 beagleboards don't tend to like USB power if that's what you're using Apr 05 21:57:57 should be ok for a beaglebone though Apr 05 21:58:05 thurbad: depends on what you are trying to do with it... Apr 05 21:58:14 I run bones off of USB power 95% of the time. Apr 05 21:58:38 jkridner: bone vs board Apr 05 21:58:44 k Apr 05 22:01:51 have tried with both a 5V supply and a USB power cable. Apr 05 22:02:25 ok, maybe pastebin your bootlog then Apr 05 22:04:41 <_av500_> +1 Apr 05 22:04:46 http://pastebin.com/mF4u8e3z Apr 05 22:04:52 <_av500_> pastebin your bootlog should be in the topiuc Apr 05 22:04:54 <_av500_> topic Apr 05 22:05:02 <_av500_> and a bot should state it once every minute Apr 05 22:05:32 wouldnt that cause questions to scroll away before people could read them? Apr 05 22:05:40 or is that the point? ;) Apr 05 22:06:06 that's some ancient bootlog Apr 05 22:06:19 Angstrom 2010.7-test-20110220 beagleboard ttyS2 Apr 05 22:06:56 <_av500_> alan_o: its Beagle LTS Apr 05 22:07:08 so I need a newer image then? link to one? (I am a complete newb at this so something simple or really good instructions would be appreciated.) Apr 05 22:07:09 LTnS Apr 05 22:08:12 yoyodyn: http://elinux.org/BeagleBoard Apr 05 22:08:25 yoyodyn: "Binaries" Apr 05 22:20:35 That page has the link to www.angstrom-distribution.org/demo/beagleboard which is where I got the image for the build that generated that log. Apr 05 22:21:12 I think... Apr 05 22:21:50 no, thats the other one. NM. I've been working with two builds today, i'll try that one again. Apr 05 22:29:24 yoyodyn: grab the uImage from that link and place it on the second partition of the SD card in the boot folder Apr 05 22:30:49 there's a legacy kernel there at the moment Apr 05 22:40:11 anyone know the BeagleBone PRU register that controls which GPIO are turned on/off? Apr 05 22:40:45 currently I have a program that turns all the GPIO on and off but I am not sure how to control it so it is just 1 Apr 05 22:46:14 Anyone know where I can find the GPIO port numbers for the GPIO_OE register? Apr 05 22:59:22 thurbad: my link or alan_o's link? Apr 05 22:59:52 yoyodyn the one you posted Apr 05 23:00:44 in the boot folder of the second partition? not the boot partition? Apr 05 23:00:59 correct Apr 05 23:01:16 and the uImage file, not the uImage-beagleboard file? Apr 05 23:01:19 newer uboot looks in that boot folder Apr 05 23:01:30 they're all the same Apr 05 23:22:12 * abcd http://goo.bot.nu/ -==Goo Bot == IRC bot==--Give a try- Apr 05 23:35:59 IRC bots spamming channels advertising themselves Apr 05 23:36:09 that's all we need Apr 06 00:16:33 jkridner, parts came today...thanks! Apr 06 00:29:49 bpetersen, do you have a good reason to use GPIO from the PRU rather than PRU native GPO/GPI pins? Apr 06 00:31:09 I heard that the GPIO can reach toggling speeds of around 2MHz Apr 06 00:32:19 what if I told you that you could toggle an order of magnitude faster than that if you use the PRUs own pins? Apr 06 00:33:12 the reason I asked you is that using the SoC GPIOs is generally inefficient and leads to performance problems when you are using the PRU Apr 06 00:36:14 bpetersen, https://github.com/beagleboard/am335x_pru_package/blob/master/am335xPruReferenceGuide.pdf is what you should read for more information Apr 06 00:38:17 note that you could toggle a pru pin muxed as an output deterministically using an XOR instruction on each cycle. one instruction a clock. Apr 06 00:38:50 when you hit the GPIO IP block on the crossbar..you lose that performance as you can have stalls..no determinism. Apr 06 00:50:09
