**** BEGIN LOGGING AT Fri Jul 26 02:59:57 2013 Jul 26 03:00:16 And a happy Friday mrpackethead! Jul 26 03:03:14 Has anyone tried clustering beagleboard blacks? Jul 26 03:08:34 dz0004455: it runs linux, you can run linux cluster software on it... Jul 26 03:08:47 not sure if beowulf though... Jul 26 03:09:12 I know I could, wouldn't be too hard to run mpi jobs across them. I am curious about performance though. Jul 26 03:10:16 considering 10 would be > $400, probably not anywhere near a cheap pc build. Jul 26 03:10:34 I speculate that I could possible get better performance with a single nice xeon chip than an a 20-30 node cluster of them. Jul 26 03:11:18 But, it would be way more fun to build a cluster... Jul 26 03:17:09 possibly Jul 26 03:19:56 prpplague: around? Jul 26 03:20:09 JoshAshby-SFE: yes but brain dead Jul 26 03:20:22 JoshAshby-SFE: just got back from doing demos at the local makerspace for 4 hours Jul 26 03:20:31 what you demo? Jul 26 03:20:46 bbb+bacon+ userspace-arduino Jul 26 03:21:11 haha, thats fine. Just wanted to know if there were any reports of the bbw a6 ethernet phy having problems outside of angstrom Jul 26 03:21:56 JoshAshby-SFE: yes there were some issues reported about if the network goes down with the ifconfig command, it never will come back up Jul 26 03:24:02 * mranostay bikes in Jul 26 03:26:34 prpplague: okay, cool. I think my problems a driver problem but thats good to know also Jul 26 03:32:28 prpplague: also nothing on my end. either that or the mail guys don't like me :P Jul 26 03:33:14 JoshAshby-SFE: sorry i havent been able to follow up on it Jul 26 03:33:31 JoshAshby-SFE: last couple of days have been crazy at the office with the release of the minnowboard Jul 26 03:33:42 JoshAshby-SFE: i'll check on it in the morning Jul 26 03:34:29 hi everyone. what are the steps for updating the eemc chip? plug it into power while holding down boot button? how long do i hold the button down for? Jul 26 03:34:47 i did it without touching the button., Jul 26 03:34:54 BBB? Jul 26 03:34:55 prpplague: haha no worries. I move in a few days anyways so I'm going to be pretty busy till school starts up Jul 26 03:34:59 yes Jungle-Boogie Jul 26 03:34:59 Jungle-Boogie: instructions are fully document both on the wiki page and the getting started page Jul 26 03:35:14 prpplague: i'll take a look. thanks Jul 26 03:35:27 it took about 80 minutes to update using the "latest angstrom" image Jul 26 03:36:22 prpplague: Insert SD card into your (powered-down) board, hold down the USER/BOOT button (if using Black) and apply power, either by the USB cable or 5V adapter. Jul 26 03:36:33 that doesn't say how long to press the button Jul 26 03:37:22 i think you can let it go by the time two leds are lit Jul 26 03:37:49 so while its updating you will see no lights coming from the BBB? Jul 26 03:37:57 you will see them dancing crazily. Jul 26 03:38:23 it's very distinctly different than it booted off the eMMC and sitting idle Jul 26 03:38:27 and once complete solid until you reboot? Jul 26 03:38:40 exactly Jul 26 03:39:13 that's exactly what I needed to know! the getting started could be updated with a brush of more info. Jul 26 03:39:33 i felt the same. 45 minutes, hah! Jul 26 03:40:15 heh Jul 26 04:03:23 JFK911: did you have your device connected USB while updating or 5v barrel? Jul 26 04:04:01 usb to computer Jul 26 04:04:17 i knew it was updating because i had no usb devices showing for it vs. when it was booted to usremode Jul 26 04:04:20 *usremode Jul 26 04:04:24 usermode Jul 26 04:05:47 okay, cool. thank you. turns out i must be short on a 5v adapter Jul 26 04:05:56 plenty of 12v, though Jul 26 04:06:36 it will run 2.5x~ as fast Jul 26 04:07:37 lol Jul 26 04:07:39 suure Jul 26 04:17:57 anyone - why does the ubuntu eMMC flashing image on uSD not require holding down the boot button but the Angstron image does? Jul 26 04:19:19 BBBK btw Jul 26 04:28:22 hi all, just received my BBB in the mail... whats the default login to angstrom? =O Jul 26 04:29:04 <[yAK]> root Jul 26 04:29:08 <[yAK]> (no pass) Jul 26 04:29:09 ssh root@192.168.7.2 Jul 26 04:29:12 <[yAK]> enter Jul 26 04:29:14 no pass Jul 26 04:29:24 im accessing via serial console Jul 26 04:29:28 ;-) Jul 26 04:29:28 usb connected Jul 26 04:29:30 like a man Jul 26 04:29:41 cbf hooking up the fancy Jul 26 04:29:58 usb is the way to do it easy Jul 26 04:30:06 <[yAK]> i just got my beaglebone black as well Jul 26 04:30:07 plus i had a TTL serial cable from my dead cubieboard Jul 26 04:30:09 plug, boot, login Jul 26 04:30:10 <[yAK]> i think i broke it tho.... Jul 26 04:30:17 <[yAK]> cloud9 no longer loads Jul 26 04:30:30 <[yAK]> not sure why not.... :P Jul 26 04:30:36 i couldn't ssh into my BBB so now i'm updating the device Jul 26 04:30:37 cloud9 is on port 3000? Jul 26 04:30:40 yeah - im kind of funny with net configs on this thing Jul 26 04:30:42 <[yAK]> BobCat: yea Jul 26 04:30:47 i dont want to break my net Jul 26 04:30:56 on my workstation Jul 26 04:31:04 so, serial console was easier for me Jul 26 04:31:06 I plugged mine in and immediate ran nmap :) Jul 26 04:31:07 <[yAK]> it just wont load up anymore not sure why Jul 26 04:31:13 cant break that! Jul 26 04:31:53 oh... perhaps I should give it ethernet... i have a spare patch lead here Jul 26 04:31:56 silly... Jul 26 04:32:00 USB Jul 26 04:32:01 easy Jul 26 04:32:05 too excited getting serial console Jul 26 04:32:21 then hooking it to my Coretex-M0+ board Jul 26 04:32:25 and going "shiny!" Jul 26 04:32:31 <[yAK]> is the only way to reflash the emmc to use a microsd card btw? Jul 26 04:32:33 as all the LEDs lit up Jul 26 04:32:35 blue bliky Jul 26 04:32:38 hehe Jul 26 04:32:50 yeah, and RGB on the FRDM-K25 Jul 26 04:32:55 if they're all lit up it's stuck Jul 26 04:33:05 i think its flashing red though - hidden under a couple of shields Jul 26 04:33:05 <[yAK]> im just planning on using this to control my bitcoin asic miners ;/ Jul 26 04:33:17 <[yAK]> rather than the laptop that is doing it right now Jul 26 04:34:57 well, thats a little odd Jul 26 04:35:18 i accidently pulled the cord out with my damn boot, and plugged it back in, now no blinkies =( Jul 26 04:35:23 hit the power button, nothing Jul 26 04:35:37 do i have to hold it down for a couple of seconds? Jul 26 04:35:41 or something? Jul 26 04:36:10 oh Jul 26 04:36:13 my bad Jul 26 04:36:24 stupid 12VDC -> 5VDC adapter Jul 26 04:36:27 its loose Jul 26 04:36:30 crisis averted Jul 26 04:36:35 hah =S Jul 26 04:37:49 the thing do DHCP on the physical ethernet connection? Jul 26 04:38:00 i mean, i do want Ubuntu on it, but im playing atm Jul 26 04:41:33 <[yAK]> Oops! Google Chrome could not connect to 192.168.7.2:3000 Jul 26 04:41:36 <[yAK]> so annoying Jul 26 05:28:24 <[yAK]> any idea why loading up 192.168.7.2 in firefox is saying "did you know? this page can interact with your beaglebone type in your beaglebone's ip address here: _________" ? Jul 26 05:31:25 hi Jul 26 05:31:31 nikunj here ? Jul 26 05:31:49 can any body guide me Jul 26 05:31:56 for beagle board Jul 26 05:32:31 hwllo Jul 26 05:32:32 ? Jul 26 05:33:05 hmmm, quiet channel... and im needing to access the microSD on a BBB after plugging it in *after* booting, as it wont boot with the card in... silly Linux workstation not recognising microSD card reader... Jul 26 05:33:20 trying to install ubuntu to the microSD Jul 26 05:33:27 ok Jul 26 05:33:34 i install it alreadyu Jul 26 05:33:39 then Jul 26 05:33:50 yeah, im still on angstrom =( Jul 26 05:33:58 need real repos Jul 26 05:34:02 ok Jul 26 05:34:34 the channel went quiet a little while ago Jul 26 05:34:48 gui based ubuntu available? Jul 26 05:34:54 id gotten a net config from a friend with a pandaboard running angstrom Jul 26 05:35:16 of course, i could be proved a liar yet, we'll see Jul 26 05:36:35 in parallel, im trying to get a FRDM-K25 board working with my Linux Mint workstation, and isnt happening either Jul 26 05:36:48 perhaps i should just flash my laser driver firmware, and pray Jul 26 05:40:27 well, that went sorse than expected... now i cant access the serial port due to the device being "busy" Jul 26 05:40:31 wunderbar Jul 26 05:54:46 well, thats annoying... i think ill let the mBed linux gurus handle that one Jul 26 05:54:57 now wheres my Macbook? at least Coolterm works as expected Jul 26 05:57:15 boris_G: currently a sdcard is not detected after boot Jul 26 05:58:44 a wonderfull JIHAD everyone! Jul 26 05:59:11 chocolate jihad! Jul 26 05:59:21 Jul 26 05:59:22 SCUD missile STARLAN number key MDA Mahmoud Ahmadinejad bomb SHA Jul 26 05:59:22 Perl-RSA data haven sniper Saddam Hussein Albania S Key terrorist Jul 26 05:59:22 spies Jul 26 05:59:55 dys: you are a minimum of 10 years out of date Jul 26 06:00:02 dys: maybe even 20 Jul 26 06:00:29 ja, M-x spook lacks some more recent developments, I'm afraid Jul 26 06:00:56 well, it's your own fault for using an OS instead of an editor ;) Jul 26 06:04:35 actually, I'm using the OS as an IRC client, not an editor :-) Jul 26 06:04:53 also, why isn't it installed by default on the eMMC? Jul 26 06:10:40 because koen choose to use angström instead of emacs Jul 26 06:16:23 boris_G: btw, debian boots nicely with a microSD inserted Jul 26 06:16:41 ...it works because it locates the root FS using UUID instead of a device name Jul 26 06:16:44 yes, it's a uboot thing which can be worked around Jul 26 06:16:54 and the kernel needs to know Jul 26 06:17:27 ja, but you need an initrd for the UUID mechanism to work, and angstrÃ¶m doesn't use any Jul 26 06:17:29 :-/ Jul 26 06:17:48 why would you? Jul 26 06:18:18 the LABEL/UUID mechanism to identify file systems on available block devices need userspace support afaict Jul 26 06:18:31 the initrd provides this before the real root system is mounted Jul 26 06:18:34 don't think so, but never tried Jul 26 06:18:51 also you could probably detect the inserted card from uboot and change the cmdline accordingly Jul 26 06:23:16 dys: do i need to do anything fancy to the Debian boot microSD? Jul 26 06:23:31 id like something i could "dd" from my mac Jul 26 06:27:03 I used the eMMC-flasher provided here: http://elinux.org/BeagleBoardDebian#Flasher Jul 26 06:28:37 theres a minor show stopper - my microSD card reader DOES NOT work on my linux workstation, only on my mac Jul 26 06:28:57 sorry to be a proverbial pain, but thems the breaks Jul 26 06:31:43 osx has dd too Jul 26 06:32:14 ja, you need unxz as well so for unpacking first Jul 26 06:32:24 yeah, unpacked it on unix Jul 26 06:32:28 I dunno how common it is in contrast ro gzip/bzip2 Jul 26 06:32:37 now want to transfer to and write on mac Jul 26 06:33:02 identify the card reader device, dd to it, ..., profit Jul 26 06:33:11 dd what? Jul 26 06:33:19 a bunch of files and directory or two? Jul 26 06:33:25 or is debian a dd image? Jul 26 06:33:28 profit? Jul 26 06:33:51 I thought you were trying to write the emmc flasher image Jul 26 06:33:58 no idea what that debian thing is Jul 26 06:34:01 im looking for an image Jul 26 06:34:05 i have ubuntu Jul 26 06:34:08 its is files Jul 26 06:34:12 cannot write via dd Jul 26 06:34:20 ok Jul 26 06:34:22 back up Jul 26 06:34:29 boris_G: If you always want to work with the microSD inserted - this worked for me too in Armstrong after changing /dev/mmcblk0p2 to /dev/mmcblk1p2 in uEnv.txt Jul 26 06:34:39 linux mint 15 workstation: cannot use microSD card reader, can unpack files Jul 26 06:34:53 after that change, it won't boot anymore without a microSD in the slot though Jul 26 06:34:54 mac, can use card reader Jul 26 06:35:06 \now, i need something i can dd on the mac, and im sweet Jul 26 06:35:18 little hard to dd some directories Jul 26 06:35:51 i have the "setup_sd.sh" or whatever on the ubuntu file after unpacking, but it dont run on my mac Jul 26 06:35:59 complains miserably Jul 26 06:36:11 and no, i dont have ports with a 64GB SSD Jul 26 06:38:06 s/Armstrong/AngstrÃ¶m/ (coffee not working yet) Jul 26 06:38:23 yeah, i cant drink it, im soldering =( Jul 26 06:38:29 heh Jul 26 06:38:45 jazzed enough as it is Jul 26 06:40:01 hmm, you don't need to run shell scripts on the host when using the Flasher approach from the link above Jul 26 06:40:08 ok Jul 26 06:40:21 i have no link cause i was dissed Jul 26 06:40:29 unplugged my modem haha Jul 26 06:40:31 just unpack, dd if=unpacked_image of=/dev/your_microsd_blockdev Jul 26 06:40:37 0827 I used the eMMC-flasher provided here: http://elinux.org/BeagleBoardDebian#Flasher Jul 26 06:40:44 yeah, ive done cubie images, i know rhat process Jul 26 06:40:49 whats the link again? Jul 26 06:40:52 taa Jul 26 06:40:55 ^^ Jul 26 06:41:04 ok Jul 26 06:41:09 gimme a few Jul 26 06:41:19 soldering crap atm Jul 26 06:42:15 dys: you dont need to unpack to dd :) Jul 26 06:42:23 from archive Jul 26 06:42:25 ;) Jul 26 06:42:27 sorry Jul 26 06:43:46 ive realised i need some caps Jul 26 06:44:03 and we have no electronics store in town Jul 26 06:44:09 anymore Jul 26 06:44:13 ebay is slow Jul 26 06:44:16 sucks Jul 26 06:44:18 =( Jul 26 06:44:19 there are still towns with electronic stores? Jul 26 06:44:29 until recently, yes Jul 26 06:44:34 and who the heck buys electronics components on ebay? Jul 26 06:44:43 20k population in the LGA Jul 26 06:45:06 ok, u have somewhere that ships to .AU for cheap? Jul 26 06:45:13 unlike most .US companies Jul 26 06:45:30 we're considered "too backwards" for cheap rates from the US Jul 26 06:45:35 the chinese dont care Jul 26 06:45:43 boris_G: it might surprise you, but not everyone knows what you mean with LGA Jul 26 06:45:51 local government area Jul 26 06:45:56 lol Jul 26 06:46:00 sorry Jul 26 06:46:03 too much aussie in me Jul 26 06:46:07 here it usually means leadless grid array Jul 26 06:46:25 moaning Jul 26 06:46:25 population of 20k leads? :P Jul 26 06:46:30 now im being an ass Jul 26 06:46:48 more coffe panto? Jul 26 06:46:55 geez, i need some Jul 26 06:46:57 :@ Jul 26 06:48:41 morning mister panto! Jul 26 06:48:45 either that, or a scotch Jul 26 06:48:47 hi there Jul 26 06:48:47 hmmm Jul 26 06:48:49 panto: how is your jihad today? Jul 26 06:48:50 decisions Jul 26 06:48:57 KotH, it's fscking hot today Jul 26 06:49:10 * KotH would say that is good Jul 26 06:49:15 panto: beach time? ;-> Jul 26 06:49:20 I'll be coming around your part of the woods for two days next week Jul 26 06:49:27 visiting some family in zurich Jul 26 06:49:42 *member Jul 26 06:52:25 i htink i need to ask my missus for a hot glue gun... Jul 26 06:52:38 * boris_G adds that to the todo list Jul 26 06:52:47 panto: if you care for a drink, let me know Jul 26 06:52:57 why I do Jul 26 06:53:16 <_SY_> hello Jul 26 06:53:28 hi Jul 26 06:54:29 <_SY_> hi panto, question for you, is there a built in watchdog process in Angsrtom that I can configure to monitor the status of my own applications? Jul 26 06:54:43 _SY_, systemd already supplies that Jul 26 06:54:55 Anyone know diameter of 5v power supply for bbb? Jul 26 06:54:57 run your app as a service, and it has a bunch of watchdog options Jul 26 06:55:06 like logging/restarting, etc Jul 26 06:55:21 <_SY_> excellent, how does it know if an application stops responding or isn't doing what its supposed to do?# Jul 26 06:55:34 oh, that's trickier :) Jul 26 06:55:39 it hasn't been solved yet :) Jul 26 06:55:53 if you manage to do that, you probably can solve the halting problem Jul 26 06:56:11 the responding bit is easier of course Jul 26 06:56:44 oh, panto... i was looking into your PRUs... im wondering how i would go about having my GRBL interpreter in Linux userland, and commanding the PRUs to run like the PID loop and switch on and off for the laser, and the steps for the stepper motors? easy to do? apart from a complete rewrite of the code... Jul 26 06:56:48 <_SY_> ok, in the past I've written an application that does the same kind of thing, and the applications have to kick an entry in a db to keep themselves alive. Jul 26 06:57:07 for instance take a look at this: http://0pointer.de/blog/projects/watchdog.html Jul 26 06:57:23 <_SY_> thank you, will do. Jul 26 06:57:25 _SY_: http://0pointer.de/blog/projects/watchdog.html Jul 26 06:57:27 heh Jul 26 06:57:29 panto is faster :) Jul 26 06:57:33 heh Jul 26 06:57:58 boris_G, depends Jul 26 06:58:09 a) how big of a code space you'll need Jul 26 06:58:10 <_SY_> Will need to look deeper into systemd :) Jul 26 06:58:13 practical merit? Jul 26 06:58:31 how big is a PID library in C? Jul 26 06:58:35 b) how much computing power does your code need to run Jul 26 06:58:50 whats the internal comms from the application processor (the A8) to the PRU? Jul 26 06:58:52 boris_G, if it's written using floating point you're dead in the water Jul 26 06:58:59 ouch Jul 26 06:59:03 probably is Jul 26 06:59:10 all it needs to do is control a fan Jul 26 06:59:12 <_SY_> PID loop is pretty simple, thing to check is that the processor is up to your timing loop....what are you trying to control? Jul 26 06:59:18 so the laser dont get too hot Jul 26 06:59:26 ^^^ Jul 26 06:59:27 <_SY_> What are the iterations for the PID? Jul 26 06:59:36 <_SY_> timing cycles Jul 26 06:59:44 i aint tuned it - 1.0, 0.0, 0.0 for the time being Jul 26 06:59:50 * boris_G is n00b to PID Jul 26 07:00:14 <_SY_> I wrote one years ago for Gas turbine control on an 8086....10ms control loop, it was a struggle, only because the processor could just about handle it. Jul 26 07:00:25 wow Jul 26 07:00:37 im told the PRU has 8k code space Jul 26 07:00:42 <_SY_> Lots of information online for PID control...do you need full PID? Jul 26 07:00:44 and 200MHYz clock Jul 26 07:00:47 nope Jul 26 07:00:54 just gotta keep the heatsink block cool Jul 26 07:01:00 probably do it with P only Jul 26 07:01:56 <_SY_> Are you just switching the fan on and off? Jul 26 07:02:01 FYI fixed point math is just about always better for stability Jul 26 07:02:08 based on temperature input, yeah Jul 26 07:02:14 yup Jul 26 07:02:22 it's a bit weird at first, but you don't suffer the accumulating error of floating point Jul 26 07:02:26 i mean, PWM of the fan would be nice, but.... Jul 26 07:02:42 boris_G, PWM is trivial too Jul 26 07:02:48 just so it doesnt blast your earsa every time it trips the setpoint Jul 26 07:02:55 yeah, i suspect it would be Jul 26 07:02:57 <_SY_> Not sure PID is really required for this....I've also used PID for ROV motor control, it was important there because you could drive motors in both directions...but for on and off, not sure you need it. Jul 26 07:03:08 suggestions SY? Jul 26 07:03:28 just a PWM control of a fan, proportional to the temperate sensed from the laser heatsink block Jul 26 07:03:38 hotter = faster Jul 26 07:03:48 until a certain point, then kill the laser completely Jul 26 07:04:57 <_SY_> I would do a search online there are bound to be plenty of examples of this kind of thing....the PID itself will be pretty standard, its the calculation of the error itself that will differ from application to application. Jul 26 07:05:24 yeah, i have no idea of the thermal response of this laser Jul 26 07:05:29 its a PoS actually Jul 26 07:05:36 im suprised it even turned on Jul 26 07:05:39 cheap++ Jul 26 07:05:48 boris_G, link? Jul 26 07:06:06 just a 405nm diode in a brass tube, out of a pointer Jul 26 07:06:09 dx.com Jul 26 07:06:13 its $6.70 Jul 26 07:06:19 <_SY_> sorry, g2g, will be back online tonight...its 0806 BST here. Jul 26 07:06:21 no docos unfortunately Jul 26 07:06:22 heh Jul 26 07:06:43 now, u'll note i cant buy pointers and import them without going to jail Jul 26 07:06:50 but i can import components Jul 26 07:06:52 weird Jul 26 07:07:34 boris_G, it just raises the barrier of import from 'jackass with some money' to 'somewhat component person with money and skills' Jul 26 07:07:42 hehe Jul 26 07:07:51 u tell the australian government that Jul 26 07:07:56 i think theyre spastics Jul 26 07:08:05 and they know what i think about them Jul 26 07:08:09 i tell them all the time Jul 26 07:09:07 tell me, if someone in germany threw the results of a land survey to gain money from mining claims, what would happen to them? Jul 26 07:09:17 i suspect jail for a long time Jul 26 07:09:24 don't bet on it Jul 26 07:09:29 here in .AU, its a media circus Jul 26 07:09:34 corruption is universal Jul 26 07:09:35 but nothing happens Jul 26 07:09:42 yeah, i suppose Jul 26 07:09:54 humans suck, film at 11 Jul 26 07:09:55 legislation allows corruption Jul 26 07:10:00 hah Jul 26 07:10:06 Parliment: The Musical Jul 26 07:11:07 still, those legislators will take my inheritance, and demand i make their lives better Jul 26 07:11:09 arseholes Jul 26 07:11:46 i used to think .AU was civilised - then i saw what my Dad just saw before her died Jul 26 07:11:53 he even Jul 26 07:11:56 crappy KB Jul 26 07:12:11 what's a KB? Jul 26 07:12:18 keyboard Jul 26 07:12:25 im getting used to it Jul 26 07:12:39 used macbook air for two years Jul 26 07:12:42 heh Jul 26 07:13:51 btw, http://www.embeddedrelated.com/showarticle/123.php Jul 26 07:13:54 The Creator Had a Mastertape Jul 26 07:13:58 mmm? Jul 26 07:14:16 shiny! Jul 26 07:14:21 ill read that later Jul 26 07:14:29 when ive finshed soldering Jul 26 07:14:36 thanks =D Jul 26 07:16:24 for the life of me, i cant find my circuit diagram folder for this =( Jul 26 07:16:33 it was on my drafting table Jul 26 07:16:35 ack Jul 26 07:16:54 (this is regular for me - i never know what is going on or where anything is) Jul 26 07:18:33 ok, found it Jul 26 07:18:37 minor miracle Jul 26 07:18:45 possibly i do have gods? Jul 26 07:18:48 hah Jul 26 07:43:11 ka6sox: Jul 26 07:43:14 :-) Jul 26 07:43:45 greetings mrpackethead Jul 26 07:43:53 how was your day? Jul 26 07:44:30 good Jul 26 07:44:39 i got ink on a big deal today Jul 26 07:47:20 https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-ash4/1073884_10151755385247661_1472913756_o.jpg Jul 26 07:49:46 looks like some weird boards ;-) Jul 26 07:49:58 gtg... bbl Jul 26 07:59:58 mrpackethead: does that mean they'll be available at some distributor at some time? Jul 26 08:00:14 dys what? Jul 26 08:00:24 waht will be avaialbe? Jul 26 08:00:45 those fpga boards - if i remember earlier discussion correctly Jul 26 08:01:00 s/boards/capes/ Jul 26 08:02:28 you can buy a pcb Jul 26 08:02:33 you just have to make it yourself Jul 26 08:02:34 :) Jul 26 08:02:41 i just made four Jul 26 08:03:34 i do have a digilent eval board lingering in my farnell shopping cart for some time now Jul 26 08:03:47 a cape sounds like an attractive alternative Jul 26 08:03:54 * dys is on a student budget, though Jul 26 08:05:25 $14 for a board Jul 26 08:05:32 about $25 for parts Jul 26 08:59:39 I wanted to ask a question on the BBB. To turn on the LCD BB I recompiled the kernel by editing the board-335evm.c (adding lcd_init ()). On the BBB which has kernel 3.8 as I do? Jul 26 09:04:04 Giulio_: if you have a older lcd, you'll need to fix the circuit, other than that it should probably just work if you load the right DT and overlays or is that even autodetected through eeprom Jul 26 09:08:09 Thank you for the answer! I have a 7 "lcd (5 +6 +5), I just have to enable the LCD outputs of the BBB, but I do not know how to do. With the BB I recompiled the kernel by modifying the configuration file of the board, but the new 3.8 kernel has changed. Jul 26 09:09:06 yes, but you need to cut a trace for it to work with the BBB. Or that's how I understood it. Jul 26 09:18:19 No, the output of the LCD BBBlack is equal to that of the BeagleBone white. Just enable the LCD output. In the BeagleBone, I changed the file board-335evm.c then recompile the kernel. So BEAGLEBONE started it thought it had lcd connected and loaded the driver and lit the LCD output. Jul 26 09:19:57 i want to install gui ubuntu on the bbb. not cui. where can i get ubuntu image file? Jul 26 09:20:09 Giulio_: there's no board-335evm.c for beaglebone, only devicetree Jul 26 09:20:18 galactic_pretty_: ubuntu.com Jul 26 09:20:34 really? Jul 26 09:24:41 galactic_pretty_: I don't think ubuntu provides images for the bb. better stick with debian Jul 26 09:25:04 hmm Jul 26 09:26:20 exact! But I do not understand how the devicetree. Jul 26 09:27:08 How do I enable the LCD output with DeviceTree Jul 26 09:28:13 debian-7.1.0-armhf-CD-1.iso <--- is it possible to install this file on the bbb? Jul 26 09:28:38 http://cdimage.debian.org/debian-cd/7.1.0/armhf/iso-cd/ Jul 26 09:38:27 I haven't tried yet, but I plan to. basically install it over a qemu armhf vm, extract the root fs then mount it over nfs using the guide posted here earlier Jul 26 09:53:24 How do I enable the LCD output with DeviceTree? Jul 26 10:04:36 Giulio_, connect the cape and it should just work Jul 26 10:07:40 panto_, is a normal lcd, lcd I need to activate the exit without the BBB read to i2c that there's LCD screen. Jul 26 10:07:52 what is a normal lcd? Jul 26 10:08:00 how is it connected? Jul 26 10:08:12 lcd 7" (5+6+5) Jul 26 10:08:13 hdmi? the lcd pins of the soc? Jul 26 10:08:28 that's not enough information Jul 26 10:10:16 hdmi do not use it. In the BeagleBone, I changed the file board-335evm.c then recompile the kernel. So BEAGLEBONE started it thought it had lcd connected and loaded the driver and lit the LCD output, but the new 3.8 kernel has changed. Jul 26 10:10:39 obviously Jul 26 10:11:04 you need to convert the changes you did in the board file to DT Jul 26 10:11:20 use one of the standard lcd cape DT file as a starting point Jul 26 10:13:06 Thank you! I might indicate the names of these files? I still do not understand much how the device tree. Jul 26 10:13:27 you need to read about it Jul 26 10:13:37 http://www.elinux.org/BeagleBone_and_the_3.8_Kernel Jul 26 10:13:51 all the cape firmware files are in firmware/capes Jul 26 10:13:58 of the beaglebone kernel tree Jul 26 10:16:14 thank you very much! I will try to study well the device tree Jul 26 10:20:34 so, are arduino capes (for the most part) directly compatable with the beaglebone? Jul 26 10:20:48 er "shields" Jul 26 10:20:49 no, heck no Jul 26 10:21:07
