**** BEGIN LOGGING AT Sun Apr 15 02:59:59 2012 Apr 15 12:28:24 GrueMaster: Thanks, that explains why it still didn't work Apr 15 20:31:52 are any of these new quad core arm's going to have hdmi? Apr 15 21:26:45 scientes: I'm sure the MX6 will, since the MX53 already does. Apr 16 00:01:04 so beagle boards run ubuntu ... how does one take a beagleboard and begin putting specific code on it? is it a USB connection? Apr 16 00:01:17 and its run in the linux environment right? Apr 16 00:02:37 delinquentme, yeah it has a RW sd card Apr 16 00:02:54 delinquentme, but binaries have to be compiled for ARM, x86 binaries wont run Apr 16 00:03:34 and this can be written in any language that can compile to ARM? Apr 16 00:03:42 correct Apr 16 00:03:57 or any interpreted language, that has interpreter support on ARM Apr 16 00:04:17 and how about the operation ... that code simply polls over and over ? Apr 16 00:04:19 and to be apecific armv7, which is what ubuntu targets Apr 16 00:04:32 delinquentme, linux is "tickless" Apr 16 00:04:42 its running *inside* the ubuntu operating system right? much like any language I run on my laptop ubuntu system Apr 16 00:04:46 so it only wakes up to meet the next deadline, if it doesn't get an interrupt Apr 16 00:05:10 yes it is the same ubuntu you run on your laptop, but recompiled for arm Apr 16 00:05:42 debian GNU/Linux did most of the porting work/troubleshooting Apr 16 00:05:54 and the code would be automatically read from the SD card? Apr 16 00:06:00 but armv7 hardfloat transition has been helped by ubuntu Apr 16 00:06:11 delinquentme, its just ext4 filesystem like you use on your hard drive Apr 16 00:06:18 so it has files just the same, and with the same layout Apr 16 00:06:41 delinquentme, you can actually run the beagleboard software on your laptop, using qemu-arm Apr 16 00:06:56 or qemu-arm-static Apr 16 00:07:40 so If i've got a desktop which connects to the beagleboard via ethernet ... and I want the beagle to issue machine commands to MCs that branch off of it Apr 16 00:08:02 " machine commands to MCs that branch off of it" Apr 16 00:08:07 i have no idea what you are saying here Apr 16 00:08:11 the beagle runs whatever compiled arm and would then issue commands via that beagleboard software to those branch MCs Apr 16 00:08:27 you can run all the same server software on e arm that you can run on x86 Apr 16 00:08:43 postfix, dovecot, postgresql, etc Apr 16 00:09:18 now, the beagleboard is not the fastest arm board Apr 16 00:09:26 basically the beagle controlling a number of attached MCs Apr 16 00:09:33 what is a MC? Apr 16 00:09:41 microcontroller Apr 16 00:09:56 specifically.....? Apr 16 00:09:59 ( sorry ) but yeah I'm trying to use the beagle to run steppers and the like Apr 16 00:10:17 been looking at this one : http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATA_BRIEF/DM00037955.pdf Apr 16 00:10:24 ~ 13 of those Apr 16 00:10:51 well that has yet another arm cpu inside of it Apr 16 00:11:03 however it has too little ram and flash to run linux Apr 16 00:11:14 oh yeah im not trying to run linux on those Apr 16 00:11:24 those are what controls the steppers and the sensors etc Apr 16 00:11:31 which then geed information back to the beagle Apr 16 00:11:37 geed = feed* Apr 16 00:12:00 is that black on the bottom audio? Apr 16 00:12:19 and the top usb is just the power (5v)? Apr 16 00:12:49 "one audio DAC" yeah, audio Apr 16 00:13:59 i think theres also a 5v in Apr 16 00:14:25 seems to me that you use the "SWD" to communicate to it Apr 16 00:15:02 "digital accelerometer and digital Apr 16 00:15:02 microphone, one audio DAC with integrated class Apr 16 00:15:02 D speaker driver, LEDs and push buttons and an Apr 16 00:15:02 USB OTG micro-AB connector. Apr 16 00:15:02 " Apr 16 00:15:05 so i guess that is what it does Apr 16 00:15:08 how to check if it can run communications over the micro usb Apr 16 00:15:22 well since it says that all that is needed, it probably can Apr 16 00:15:51 what do you want to do with it? Apr 16 00:16:07 make a liquid handling robot Apr 16 00:16:18 it has a number of modular cores Apr 16 00:16:34 that thing seems to be audio-oriented Apr 16 00:16:42 microphone and mono audio out Apr 16 00:17:02 yeah I'm not really sure how the MC industry works Apr 16 00:17:07 "digital microsoft" (does that mean it has a ADC ?) Apr 16 00:17:19 like it can send signals and thats all I really need Apr 16 00:17:32 i could probably go much simpler TBH Apr 16 00:17:33 gcc supports compiling firmware IIRC Apr 16 00:17:52 its the arm-non-gnueabi target for armv5+ Apr 16 00:17:56 *none Apr 16 00:17:59 but I dont have the capability to design printed circuit boards ... so i need to buy something thats already assembled Apr 16 00:19:23 and it only has one usable button Apr 16 00:19:26 so yeah just write come C code .. compile it with GCC stick it on a MC like that and let it poll for commands from the beagle Apr 16 00:19:49 yeah I don't really see myself using anything other than a reset button Apr 16 00:19:53 well, event-based would sure be nicer Apr 16 00:20:06 delinquentme, you can do that without any MC Apr 16 00:20:12 you can do that with a seial port Apr 16 00:20:28 or even a usb keyboard/mouse Apr 16 00:21:22 well for programming it I can attach it however Apr 16 00:21:24 but yeah that board is designed for audio uses, it doesn't seem applicable for you Apr 16 00:23:08 how does one go about finding a good board for an application? Apr 16 00:23:31 all the IC vendors have huge lists Apr 16 00:23:34 ( i'm kind of expecting there to be a tool like new egg where there are drop downs and I select the chips and things I want on it Apr 16 00:23:42 freescale, marvell, broadcom Apr 16 00:23:49 newark Apr 16 00:23:55 and these are all programmed effectively the same way? Apr 16 00:24:19 well im still not sure what youwant/are trying to do Apr 16 00:25:08 arduino is pretty hot these days Apr 16 00:25:44 true but they're also super costly Apr 16 00:26:21 so is the beagle board Apr 16 00:26:26 ahh yeah that might help :D .. I've got 2 steppers, 1 linear string pot, 1 linear actuator and 2 physical switches Apr 16 00:26:37 compared to, like, the rasberri pi Apr 16 00:28:38 delinquentme, how about this: http://www.st.com/stonline/stappl/productcatalog/app?page=productSelectorPage Apr 16 00:30:07 oooooo Apr 16 00:30:14 http://www.freescale.com/webapp/sps/site/application.jsp?code=APLSTEMOT Apr 16 00:34:05 DSC ? Apr 16 00:34:19 Digital Signal Controller Apr 16 00:36:08 actually I should totally be able to email customer support @ these places and just be like Apr 16 00:36:12 "this is what I need" Apr 16 00:36:15 does u have? Apr 16 00:36:29 also! Apr 16 00:36:46 these are all chips .. is there a name used for the units when they're already attached to a board? Apr 16 00:38:14 yeah ive come across that prob too Apr 16 00:38:25 i dont really have an answer for you Apr 16 00:40:21 haha im glad im not nuts :D Apr 16 00:40:28 scientes, what do you do with all this coolness Apr 16 00:40:34 specifically ubuntu arm chips? Apr 16 00:41:37 well i actually dont have a armv7 comp yet Apr 16 00:41:41 i only have the sheevaplug Apr 16 00:41:48 which is armv5, running debian Apr 16 00:42:02 but i really want a armv7, or better yet armv8 + quad core Apr 16 00:42:11 * scientes wants to experiment with big.LITTLE too Apr 16 00:42:40 OOo the sheevaplug Apr 16 00:42:48 thats like mischief no? Apr 16 00:42:48 its kinda old now Apr 16 00:43:30 is this like PHD research scientes ? Apr 16 00:44:44 you can basically hook that sheevaplug up to something and just let it sniff away at wireless packets Apr 16 00:46:37 the one i have doesn't have wifi Apr 16 00:47:02 but considering its size and power consumption that sort of use would certainly be feasable Apr 16 00:47:07 and a good fit for the device Apr 16 00:47:34 it also has gigabit ethernet, so you could access it remotely at high speed Apr 16 02:08:51 configure: error: "PAM libraries not found" Apr 16 02:08:58 how to fix ? Apr 16 02:11:36 configure: error: "PAM libraries not found" how to fix ? Apr 16 02:13:23 pnphi, what piece of software? Apr 16 02:14:22 i'm building the package gdm Apr 16 02:15:18 This error is coming from ./configure ? Apr 16 02:16:37 no , dpkg-buildpackage -aarmel Apr 16 02:16:54 pnphi, could be systemd-logind's pam module Apr 16 02:17:03 try turning off systemd Apr 16 02:18:25 dpkg-buildpackage: error: debian/rules build gave error exit status 2 Apr 16 02:18:32 and this problem Apr 16 02:19:27 pnphi: pastebin the full transcript Apr 16 02:19:41 detail ? Apr 16 02:25:05 I assume you're missing libpam-dev. Apr 16 02:26:09 infinity: I thought dpkg-buildpackage would, like debuild, bitch about missing dependencies before getting to that point Apr 16 02:26:20 It does. Apr 16 02:26:29 So he's doing something silly. Apr 16 02:26:36 And the pastbin will tell us what Apr 16 02:26:58 But he may well either (A) have built with -d, or (B) be building sources with bad build-deps. Apr 16 02:27:11 Nod Apr 16 02:28:46 (When you call debuild, it's dpkg-buildpackage that's bitching; debuild is only a very thin wrapper around it) Apr 16 02:58:56 checking for pam_start in -lpam... no configure: error: "PAM libraries not found" make: *** [debian/stamp-autotools] Error 1 dpkg-buildpackage: error: debian/rules build gave error exit status 2 Apr 16 02:59:09 I don't know to fix this problem Apr 16 02:59:11 !!! **** ENDING LOGGING AT Mon Apr 16 02:59:58 2012
