**** BEGIN LOGGING AT Thu Feb 26 02:59:59 2015 Feb 26 03:00:31 it assumes there are two partitions Feb 26 03:00:43 oh right Feb 26 03:00:56 you can also fix the script, search for fdisk and you'll see the problem Feb 26 03:01:00 is /boot not one? Feb 26 03:01:10 i get the impression /boot is a big magical Feb 26 03:01:24 oh dunno that depends on what you're using I guess Feb 26 03:01:32 it probably used to be, since the script expects it Feb 26 03:01:44 but isn't anymore in debian-testing images anyhow Feb 26 03:02:09 ah wait, SD card always has a boot partition Feb 26 03:02:27 so ROM can find the MLO file Feb 26 03:03:11 in that case the script will indeed work fine Feb 26 03:03:28 (ROM can use a boot partition with MLO file on eMMC also) Feb 26 03:04:56 holy crap creating a .xz file takes forever Feb 26 03:05:12 why would you create an xz if you already have a raw image? Feb 26 03:05:13 zmatt: oh ok -- what case were you using where you didn't have two partition? Feb 26 03:05:21 oh right, the script expect it Feb 26 03:05:22 zmatt: the tool says it requires a .xz image Feb 26 03:05:23 hehe Feb 26 03:05:39 so you're compressing it now just so the script can decompress it again Feb 26 03:05:44 yep =\ Feb 26 03:06:36 you can also just do sudo ./usb_flasher and then dd the image yourself to the "usb stick" that newly appears Feb 26 03:07:15 oh my god this script is really horrible, whoever wrote it has no idea how to do bash scripting Feb 26 03:07:38 zmatt: i'll try the script first to make sure it works Feb 26 03:07:49 like Feb 26 03:07:55 after=($(ls /dev | grep "sd[a-z]$")) Feb 26 03:07:59 instead of the intended Feb 26 03:08:02 after=(/dev/sd[a-z]) Feb 26 03:08:11 heh Feb 26 03:14:31 zmatt: ... it's working Feb 26 03:15:42 zmatt: wow this is fantastic Feb 26 03:16:16 it's interesting to watch the ftdi output Feb 26 03:20:15 zmatt: Feb 26 03:20:16 resize2fs: Bad magic number in super-block while trying to open /dev/sdb2 Feb 26 03:20:16 Couldn't find valid filesystem superblock. Feb 26 03:20:18 does that seem bad? Feb 26 03:22:43 it appears that i am unable to boot, it just hangs =\ Feb 26 03:26:47 zmatt: what would i need to do to fix the partition like you suggested? Feb 26 04:02:15 actually it works with a normal image Feb 26 04:02:27 i disabled xz from the script, maybe that was it. or truncate. Feb 26 04:05:26 maybe you truncated it too short? Feb 26 04:05:55 zmatt: could be -- trying non-xz now. if its broken, perhaps i did Feb 26 04:06:15 very, very good feeling to know this tool works though. i owe you a beer zmatt Feb 26 04:06:19 well if resize2fs fails with such an error there's no point in trying to flash it Feb 26 04:06:24 heh Feb 26 04:06:36 yeah it was saying that my super blocks were corrupt Feb 26 04:06:46 which I think ext4 puts near the end of the fs Feb 26 04:08:41 so that would be consistent with over-truncation Feb 26 04:08:58 i mean, i trunced at 2GB. partition is 1.8gb Feb 26 04:09:37 located at which offset from the start of the disk? :) Feb 26 04:11:31 hah. Feb 26 04:11:44 zmatt: in that case, is there any way to create a shrunken image from an sd card? seems like it should be easy enough Feb 26 04:11:56 it's just an arbitrary size -- i coul dhave a 120gb SD card Feb 26 04:12:21 truncation should still work, as long as all partitions are located within the truncated image :P Feb 26 04:12:33 Pass 1D: Reconciling multiply-claimed blocks Feb 26 04:12:34 (There are 2 inodes containing multiply-claimed blocks.) Feb 26 04:12:36 so it's not an error Feb 26 04:12:41 but it does want me to do something Feb 26 04:13:45 it had me fix a bunch, basically everything i installed had some kind of node issue Feb 26 04:13:49 interesting Feb 26 04:13:56 if this works i should just create a new image from this emmc Feb 26 04:14:35 zmatt: it worked! or at least, it appears to have worked Feb 26 04:14:41 i guess i dont actually know if i'm missing data lol Feb 26 04:15:08 it doesn't sound good anyhow Feb 26 04:15:12 /dev/mmcblk0p2 3.5G 2.2G 1.2G 66% / Feb 26 04:15:22 1) xz screwed it up (it at least works without it) Feb 26 04:15:26 2) i may have cut off .2 gb hehe Feb 26 04:15:51 awesome. i'm going to re-do with 3gb truncate to see if i have any luck Feb 26 04:15:58 interesting that xzcat would have screwed the pooch so hard Feb 26 04:16:14 you can get the actual start and end offset with fdisk -l Feb 26 04:16:22 (works on a file too) Feb 26 04:16:46 use (end sector + 1) * 512 as truncation size in bytes Feb 26 04:17:06 /dev/sdb1 * 2048 7553023 3775488 83 Linux Feb 26 04:17:40 note that the script recreates the partition table Feb 26 04:17:49 so no use in checking it after that Feb 26 04:18:03 check the original image Feb 26 04:18:04 that's my SD card, not the BBB Feb 26 04:18:06 ah ok Feb 26 04:18:29 ehh, huh Feb 26 04:18:33 yeah it seems kind of high Feb 26 04:18:44 * zmatt scratches his head Feb 26 04:19:00 zmatt: nm. you're correct, i'm dumb Feb 26 04:19:12 i must have been looking at the wrong image -- this one is 3.6GB Feb 26 04:19:16 it could be me, but I'm pretty sure that 2048 + 3775488 - 1 isn't equal to 7553023 Feb 26 04:19:21 and it uses 2.4GB Feb 26 04:19:25 so i *definitely* cut off some junk Feb 26 04:20:26 heh Feb 26 04:20:45 I still don't understand that end-sector number though Feb 26 04:21:10 me neither, although i don't entirely understand what it should be Feb 26 04:21:17 also, it's partition 1? Feb 26 04:21:35 where'd the boot partition go? Feb 26 04:21:42 yeah you're right. i guess i don't have a boot partition Feb 26 04:22:10 ehh, then I don't see how it could boot Feb 26 04:22:25 ¯\_(ツ)_/¯ Feb 26 04:22:35 heh -- couldn't resist Feb 26 04:22:48 lol Feb 26 04:22:50 all i know is that this is the same image that *does* boot, so i'm guessing the uboot (?) is OK with how it's set up Feb 26 04:24:28 with the sd button pressed? (I vaguely recall the tendency to boot from SD even without pressing the SD button if a /boot with suitable contents was present) Feb 26 04:26:07 there are some annoying routes the startup can take, e.g. SPL from one device can end up loading the u-boot from another, and u-boot can also boot a kernel from either device... I know I've had funny run-ins with that sort of stuff in the past Feb 26 04:26:57 (since I discovered that BBBlfs tool I haven't used SD at all anymore) Feb 26 04:30:11 but the TRM claims a FAT partition is required to boot from cards, it only tries the "raw" layout on eMMC/eSD Feb 26 04:30:32 (of course, it wouldn't be entirely unprecedented if the TRM turns out to be talking out of its ass, but still) Feb 26 04:39:10 zmatt: missed the mark by 60mb (doh) but even with dd running out of space, boots great Feb 26 04:39:24 just re-truncated at 3.9GB (should have done it at 3.866 gb) but now it boots no prob Feb 26 04:39:46 zmatt: my BBB does not boot from SD unless i hold down S2 which is a big pain (literally) when i have an audio cape on, so this is great Feb 26 04:40:53 if the audio cape has pass through of the P8 connector, you can also emulate the S2 button with a pull-down resistor on pin 43 Feb 26 04:42:16 (more generally, pins 31-46 of P8 connect to lcd data 0-15 in an awkward order, which are sampled at power-on reset to become sysboot 0-15 which decide the boot options) Feb 26 04:42:50 zmatt: very cool Feb 26 04:43:01 zmatt: i take it you learned by experience there? Feb 26 04:43:50 I used it to enable network booting (so far only of a small baremetal application, haven't tried loading u-boot that way yet) Feb 26 04:44:39 cool Feb 26 04:45:21 see also the "BBB" and "Boot" tabs of this spreadsheet -> https://docs.google.com/spreadsheets/d/1CK5c-Cs8G1RtzGo-J3VJsD9m5K-fp06AncgeYWsdjSU/view Feb 26 04:46:16 the BBB sheet also has a filter view (menu Data -> Filter views) "CAPE" to list only cpu pins available on external headers Feb 26 04:53:25 you do need to use a suitable pull-resistor... since you need to overcome the default pull-up/down resistors yet not cause too much current when the virtual hdmi cape is loaded and the pins are configured as outputs Feb 26 05:02:12 (oh, small caution: my spreadsheet consistently uses 0-based indexing, while the TRM and kernel use an inconsistent mix of 1-based and 0-based numbering, sometimes both in different places) Feb 26 05:04:52 heh, cool thanks Feb 26 07:01:17 Hi Feb 26 07:01:51 is Beaglebone Black RevC 4GB support android ? Feb 26 07:02:49 there probably are android builds by someone, probably even TI Feb 26 07:02:59 I don't see people here using it much though Feb 26 07:57:08 . Feb 26 07:57:20 Hi Feb 26 08:05:19 Nagraj: ask here or go away Feb 26 08:32:54 How perform lift simulation practical using beagleboard Feb 26 08:33:24 How to perform lift simulation practical using beagleboard Feb 26 08:33:31 please help me Feb 26 08:38:28 ??? Feb 26 08:38:32 perform what? Feb 26 08:39:01 gm Feb 26 10:46:26 hi canu u help me know how to set vendor id in beaglebone black Feb 26 10:47:00 what for? Feb 26 10:48:13 for serial port communication Feb 26 10:48:27 in android os Feb 26 10:48:45 how to set vendor id Feb 26 10:49:55 ah its you again Feb 26 10:50:03 hey Feb 26 10:50:06 the answers to your questions have not changed Feb 26 10:50:19 asking them all over again wont help you much Feb 26 10:50:35 no i got disconected Feb 26 10:51:08 no Feb 26 10:51:15 you asked that already a month ago Feb 26 10:52:14 i was tryin to communicate beagle bone black with an application on mobile device via usb cable. but i need to find the vendor id > can anyone help Feb 26 10:54:56 lsusb Feb 26 10:56:42 i tried using lsusb and i got a value is dat vendor id . and can we use dis id to find product id Feb 26 11:04:46 yes Feb 26 11:10:37 is product id and vendor id unique for beaglebone black or user editable Feb 26 11:11:15 all user editable at some point Feb 26 11:14:16 so for communication from beaglebone black running android to android mobile device connected by usb how can we edit the vendor and product id Feb 26 11:19:45 alter the kernel modul Feb 26 11:37:28 nbg_: communicating to android from bbb requres you to change usb ids? why so? Feb 26 11:52:05 i couldnt find the vendor and product ids Feb 26 11:52:24 so either i have to find them or change them. Feb 26 11:54:01 can we use ftp driver for finding the ids Feb 26 11:54:21 but hw do i install ftp driver Feb 26 13:08:28 hii..want to know that is there any bug tracker where we can solve bugs ?? Feb 26 13:08:43 which is a good sign that a student is capable of taking up gsoc project too or if a student can even start exploring the project from ideas page and does some ground work and shows its capabilities... Feb 26 13:08:46 so which student is more favoured ?? Feb 26 13:08:55 anyone plss ?? Feb 26 13:13:00 chint: you should check out #beagle-gsoc for gsoc related stuff Feb 26 13:13:43 so we can start exploring the projects in which i am interested in ?? Feb 26 13:54:56 Hi Feb 26 13:55:29 I dont have the file 'interfaces' in the folder : /etc/network/ Feb 26 13:55:55 I just flashed my BBB with the latest Angstrom image Feb 26 13:56:25 we switched to Debian a while ago Feb 26 13:56:31 you might want to do that too Feb 26 13:57:41 oh yeah? I switched to Debian yesterday and I tried to run a binary and I had trouble with a libsc++.so.6 so I changed back to angstrom Feb 26 13:57:54 but ok I'll do that. Thank you. Feb 26 13:58:23 you need to compile for the right target... Feb 26 13:59:09 I tought that If it worked on angstrom, it would be working on Debian Feb 26 14:04:37 How do I connect to this IRC from an IRC client? Feb 26 14:04:42 like mIRC Feb 26 14:04:48 sorry I'm new to that Feb 26 14:05:29 test Feb 26 14:05:33 ok got it lol Feb 26 14:38:23 i have a question regarding bonescript ... how can i run an executable file using bonescript ? Feb 26 15:25:03 hi Feb 26 15:25:36 hello/ Feb 26 17:20:16 hi! i am new to beaglebone Feb 26 17:21:41 i have a problem with linking it to http://beagleboard.org/getting-started but its not connecting unlike as in video there Feb 26 18:07:04 hello Feb 26 18:10:41 quick question! if I install some other distro on the beagle bone, can I still access its microSD from my PC using the USB cable? Feb 26 18:11:47 I mean, is this a feature independent of the linux distro or is it done by some service running on the Angstrom linux system? Feb 26 18:18:02 humm... anyone there? Feb 26 18:20:03 ZZZZzzzzzzzzz..... Feb 26 18:22:11 quick question! if I install some other distro on the beagle bone, can I still access its microSD from my PC using the USB cable? Feb 26 18:22:47 pedro_nf: you'd need to make sure g_gadget is installed and working correctly Feb 26 18:23:01 (i think) Feb 26 18:23:43 humm... so you say that the access to the microSD via USB is a service running on linux Angstrom? Feb 26 18:24:08 yeah -- g_gadget (i think) enables IP over USB, serial over USB, and mass storage over USB all at once Feb 26 18:24:29 http://www.linux-usb.org/gadget/ -- see "Mass Storage Gadget" Feb 26 18:24:39 you could alternatively do just mass storage, with another driver i'm sure Feb 26 18:24:47 i use just g_serial because g_gadget is not stable in my image Feb 26 18:25:24 pedro_nf: you could do mass storage only: http://www.linux-usb.org/gadget/file_storage.html Feb 26 18:25:47 ok, let me check it out Feb 26 18:26:13 does anyone know how to reset wlan counter? I used an old wifi chip, that i dont have now, and so my new one is always wlan1 Feb 26 18:26:43 i think i got it, may be a udev thing Feb 26 18:27:27 what distro are you using? Feb 26 18:27:52 have you tried removing it? and then add it again? Feb 26 18:28:06 pedro_nf: just a custom build of debian. g_gadget may work, but once i realized that g_ether was not working properly I scrapped it and just used g_serial Feb 26 18:28:19 so i didnt check to see if mass storage was even working Feb 26 18:29:33 are you talking about the service that runs on your PC that accesses th ebeagle bone? Feb 26 18:29:42 of the service that runs in the beaglebonew? Feb 26 18:30:15 in order to use ssh to get into the beaglebone over USB, g_gadget has to be set up correctly (or g_ether i think) on the beaglebone. my linux laptop just knows what to do from there with the driver Feb 26 18:30:36 ah ok Feb 26 18:30:43 but if usbnet0 is not online on the BBB -- it won't work Feb 26 18:31:05 so if I install some other linux distro then I can't access it via USB Feb 26 18:31:15 unless I reinstall that service Feb 26 18:31:30 probably -- unless that distro has it available by default Feb 26 18:31:41 pedro_nf: i ended up just using the FTDI cable since the usb wasn't reliable Feb 26 18:32:13 pedro_nf, the usb-serial/usb-flash/usb-ethernet is all a customization we do on bootup with an initr script... Feb 26 18:33:29 ok now I understand! Feb 26 18:33:50 thank you for clarifying this Feb 26 18:34:03 blaine and rcn-ee Feb 26 18:34:07 you can see the dirty details here: Feb 26 18:34:10 https://github.com/RobertCNelson/boot-scripts/blob/master/boot/am335x_evm.sh Feb 26 18:34:35 glad i could help Feb 26 18:34:37 g_multi here: https://github.com/RobertCNelson/boot-scripts/blob/master/boot/am335x_evm.sh#L96 Feb 26 18:34:41 ok I'll look it up Feb 26 18:34:55 rcn-ee: is g_multi the same as g_gadget? Feb 26 18:35:00 i may have been wrong about the name Feb 26 18:35:01 uah lots of reading :-) thanks Feb 26 18:35:23 g_multi is a gadget driver that loads g_ether, g_serial, g_ether.. ;) Feb 26 18:35:37 last ether, the usb-flash one.. Feb 26 18:36:02 oh ok cool. Feb 26 18:36:11 just to finish, one more question... Feb 26 18:36:31 any of you guys have a strong opinion on the linux distro? Feb 26 18:36:40 the best one? Feb 26 18:36:49 pedro_nf: debian is widely used by most people here i think Feb 26 18:37:02 pedro_nf, debian is the default... but use what you want... "most" things should be distro dependent.. Feb 26 18:37:12 dependent/independent... Feb 26 18:37:24 I've seen some people talking good about arch Feb 26 18:37:56 there is also the yocto project Feb 26 18:37:57 https://www.yoctoproject.org/tools-resources/videos/tuning-linux-embedded-systems-when-less-more-elce-2011 Feb 26 18:38:31 pedro_nf: all depends on how much config you want to do. rcn-ee has fresh debian images that are really nice Feb 26 18:38:54 and the qnx Feb 26 18:38:55 http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/TiAm335Beaglebone Feb 26 18:39:18 well, sorry about so many questions... I'm just starting to use the beaglebone Feb 26 18:39:23 complete newb Feb 26 18:39:33 I work with PLCs Feb 26 18:39:40 industrial automation Feb 26 18:39:55 I'm trying to make a small embedded platform for my prototypes Feb 26 18:40:02 pedro_nf: summary: if you "just want it to work" use a fresh debian image. if you want to feel around, use anything -- there's a bunch out there Feb 26 18:40:06 stable and quick programming Feb 26 18:40:28 or download them all, save the image files and flash to sd cards -- you can switch out very easily Feb 26 18:40:55 yeah I think I'll try a few of them Feb 26 18:41:09 I'll publish my findings later in the forum Feb 26 18:41:18 I just need to find the time... Feb 26 18:41:32 thats the problem of being an independent contractor... Feb 26 18:41:36 always running Feb 26 18:42:15 I'll look into rcn-ee debian images Feb 26 18:42:22 where are thy? Feb 26 18:43:08 http://elinux.org/BeagleBoardDebian#BeagleBone.2FBeagleBone_Black Feb 26 18:43:44 http://elinux.org/BeagleBoardDebian#BeagleBone.2FBeagleBone_Black Feb 26 18:43:46 oops sorry Feb 26 18:43:51 http://elinux.org/BeagleBoardDebian#Debian_Testing_.28jessie.29 Feb 26 18:44:48 ok, thank you very much blaine! Feb 26 18:45:08 you're welcome -- glad to help Feb 26 18:47:53 yeah you really helped and much more efficient then looking around for all this info that I couldn't find any answers Feb 26 18:50:17 pedro_nf: that's what's nice about this channel -- many others have helped me many times over Feb 26 19:02:26 Hello... is there any way to use RF 433 modules on BBB ? Feb 26 19:03:45 sure Feb 26 19:06:15 Humpelstilzchen, do you have any doc? because I only found docs mean usage this module with arduino and BBB Feb 26 19:09:17 ccesario: it all highly depends on the 433Mhz module you want to use and you will probably have to do a lot of work Feb 26 19:10:06 you can use spi Feb 26 19:11:19 https://github.com/gkaindl/rfm12b-linux Feb 26 19:16:35 there ara some process using a rcswitch program... but it seems that rcswitch does not work on BBB Feb 26 19:31:44 pff rfm12 is soo old :) Feb 26 19:34:39 yes but works fine Feb 26 19:38:51 if rfm12 is old, how about those rf433 modules then? :) Feb 26 19:40:00 less complicated Feb 26 19:41:45 that reminds me, i'll have to finish my next cape with ti cc1101 transceiver Feb 26 19:42:50 ooohhh nice Feb 26 20:12:38 Humpelstilzchen and Catslab ... thanks... I ĺl read about it....!!! Feb 26 20:15:08 if will is is possible implement this http://smarthome.hallojapan.de/2014/11/controlling-lights-with-openhab-raspberry-pi-and-433mhz-remote-switches/ with BBB ? Feb 26 20:16:37 the "magic" is done by rcswitch programs .... but I think that it is not supported by BBB due wiringPI library Feb 26 20:21:55 looks like it's done by gpio bit banging for tranmission Feb 26 20:22:04 ccesario: shoudl be doable on BBB Feb 26 20:23:59 https://github.com/r10r/rcswitch-pi as describe there.... "First you have to install the wiringpi library." Feb 26 20:24:04 only in PI :( Feb 26 20:25:59 yes or build your own library, there must be something similar for BBB Feb 26 20:27:25 Catslab, I dont have expertise for this :) Feb 26 20:28:10 https://github.com/piranha32/IOoo Feb 26 20:29:49 thanks... I ĺl read it Feb 26 21:09:38 hi Feb 26 21:10:19 Getting this error java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver Feb 26 21:10:30 when running through beagle bone Feb 26 21:10:38 any help? Feb 26 22:30:41 Hello, I tried setting up my beagleboard-XM following http://archlinuxarm.org/platforms/armv7/ti/beagleboard-xm. However, when I plug in my keyboard, lan-cable and monitor, my router does not detect a new device and my monitor does not get an HDMI signal. Does that mean that my device is broken? Feb 26 22:31:10 Are you also applying power to the board? Feb 26 22:31:25 agmlego: yes, a red light is illuminated Feb 26 22:51:09 Or is there maybe another way of checking if my device is still alive? (apart from the serial port, I currently don't have the adapter) Feb 26 22:59:33 kpj: One quick and simple way is to plug in a USB device that can indicate that it has power, like an optical mouse or a keyboard after pressing Caps Lock, Num Lock, or Scroll Lock. Feb 26 23:32:40 pehjota: Thanks for the tip! The Caps Lock light on my keyboard did not turn on :-( Feb 26 23:32:52 Couldn't this also mean that it is tuck somewhere in the boot process? Feb 27 00:14:27 kpj: Jacobs University Bremen ? Feb 27 00:15:24 vvu: Yes? :-) Feb 27 00:30:07 has anyone done hardware interfacing with their BBB (a bit more than using I2C or spi that is) Feb 27 00:37:31 Yes. Feb 27 01:46:02 kpj: Yeah, that likely signifies that your kernel (Linux) is hung, panicing, or not booting or that your bootloader (MLO/SPL or U-Boot) isn't booting. Feb 27 02:35:11 sorry stepped out (heh) I was looking at the power sub system on the BBB is 2A for the 5V supply adequate with decoupling caps near the connector? Do I need to consider high speed bus use for using any of the SPI bus etc? The PRU seems to be unuseable for high speed communication so straight to the main processor seems the last route available. I couldn't find more than 2 USB DM / DP connections and they are both Feb 27 02:35:11 routed on the board (IE I can't make an embeded USB hub on the thing either). Feb 27 02:36:36 GenTooMan: Maybe if you gave me more details on what you are trying to do, or even just asked a question, I might be able to help. Feb 27 02:38:04 2A @ 5V is recommended if you want stable operation of the board, and want to power things off the USB port. If you need no USB power, you can get away with 1.5A. Feb 27 02:38:05 I was planning on connecting a high speed SPI (37mhz) device however I'm concerned about the noise (1.8V bus single ended) Feb 27 02:38:29 37MHz is pretty high clock rate for SPI, are you sure the slave device supports that high a clock frequency? Feb 27 02:40:33 Ok I was looking in terms of general PSU I was thinking of a USB keyboard into the main USB Host connector but I also would like to allow a USB flash drive too so hmmm hub was my next though. And yes it does. I was thinking of slaving it straight to the BBB however noise wise since it's actually a precision analog device I am really puzzled. So I'll have to rethink that. Feb 27 02:40:40 eh, you can't make 37 MHz, it's either 48 or 24 Feb 27 02:41:00 since McSPI gets an 48 MHz functional clock Feb 27 02:41:27 GenTooMan: "precision analog device"...and yet you are wooried about noise from the SPI bus? Feb 27 02:41:27 thanks zmatt I did read the data sheet but DAMN it's huge. Feb 27 02:41:42 GenTooMan: still very incomplete though Feb 27 02:41:52 GenTooMan: I suggest using the manufacturer's exact board layout example for the chip you want to use, and everything will be fine. Feb 27 02:42:07 8 24bit delta sigma converters? Feb 27 02:42:24 As for USB...it is *always* recommended to use a powered USB hub to avoid tears and sadness. Feb 27 02:42:44 GenTooMan: Again, use the application note or provided board layout diagram in the part's datasheet. Feb 27 02:42:59 GenTooMan: If the manufacturer of the part neglected to provide those, choose a different part. Feb 27 02:43:25 good advise. Feb 27 02:44:36 I was thinking I might be able to "use A PRU" however it's not looking so good after looking at what pins are available. :D Feb 27 02:46:49 Looks like I have a bit of layout fun ahead of me. Feb 27 02:47:32 Thanks again it's better to ask crazy questions than guess. Feb 27 02:47:37 point-to-point transmission lines are not *very* hard to get right, ... now once it becomes a star topology that's when the real pain begins (several TI SoCs have a second chip-select for EMIF, but officially defeatured... maybe there's truly something wrong with it, but I wouldn't be surprised they just don't want a ton of customers with a board they can't get to work) Feb 27 02:48:29 of course DDR is a bit trickier still than 48 MHz SPI ;) Feb 27 02:53:00 GenTooMan: note btw that if you don't need hdmi you can repurpose those pins (e.g. for PRU) Feb 27 02:54:12 but I love pretty pictures! Actually I need the LCD lines to be precise (800x480 7" LCD) I'll have too look to see if I can mess with the mux some to use alt lines. Feb 27 02:55:47 My guess is I'll end up using a low end FPGA and grab the data from the A2D's from that (sigh) nothing is ever simple. Feb 27 02:55:58 ultimately the am335x is still a pretty small SoC, if you want crazy stuff wait for vayu ;P Feb 27 02:56:08 hmm, speaking of, is it released yet? Feb 27 02:56:30 You mean the new SoC's for car infotainment? Feb 27 02:57:07 the crazy thing of which the "lite" version is the am527x on the beagleboard-x15 Feb 27 02:57:26 (the high-end versions aren't for car infotainment but ADAS btw) **** ENDING LOGGING AT Fri Feb 27 02:59:58 2015
