**** BEGIN LOGGING AT Mon Aug 21 03:00:02 2017 Aug 21 05:38:19 Hi Aug 21 07:56:20 thanks zmatt. have you used it? you use CCS,r ight? Aug 21 07:58:30 Hello! I am using the Beaglebone Black and the latest IOT image. After installing x11 on this image i get ext4 corruptions after a few uncotrolled power offs Aug 21 07:59:44 Back again Aug 21 08:02:26 hello Aug 21 08:16:49 ayjay_t the school is getting me a Bus Pirate, will try to use it for JTAG with the BBB Aug 21 08:17:11 anyone here used the BP with BBB? Aug 21 08:20:19 moondeck: What do you plan to do with the BBB that you need a JTAG for? Aug 21 08:21:00 Humpelstilzchen i am developing an OS for it, bare metal. Aug 21 08:27:40 How do I configure UART1 on the p9 connector of BBG as debug port Aug 21 08:28:06 can any one help me on this please Aug 21 08:44:16 i think that the bus pirate is definitely an asset for any embedded development, but i bet the TI native debugger is more convenient Aug 21 08:44:25 for sitara jtag at least Aug 21 09:36:47 has anyone successfully ported Android on BBG Aug 21 09:37:00 I am unable to find the patches for BBG Aug 21 09:37:38 I am using UBANTU 17.04 in my host system Aug 21 09:38:00 and followed the same steps for porting android on BBB Aug 21 09:59:54 hi all, can someone know how can i stop the annoying network job at BBB startup? Aug 21 11:16:45 cyberg: disable it? :) or use a network manager that doesn't block startup (ifupdown blocks startup, systemd-networkd and gnome network manager don't, no idea about connman) Aug 21 11:18:56 ayjay_t: yeah I've done some jtagging of the am335x, typically with CCS (or the commandline interface to its debug server) Aug 21 11:42:33 I've used openocd too, but TI's own software definitely has better support for TI SoCs :P Aug 21 12:47:33 I've got a jessie image on my BBGW, just curious if it is a safe upgrade path to modify the source.list to say stretch instead of jessie like one would with a normal (non-embedded) dibian system? Aug 21 12:52:23 freemor: in theory yes, but disk space may be a problem Aug 21 12:53:27 I've done jessie -> stretch upgrades on console images though Aug 21 12:59:21 also, kernel and bootloader don't update automatically Aug 21 13:05:59 Thanks, running from SD card so space should be fine Aug 21 13:06:48 do you have a link to correct steps to upgrade kernel/uBoot Aug 21 13:08:30 I'll probably dd the card onto a spare one. try the upgrade on that.. That way I can fall back to the orig. if it all goes Wonky Aug 21 13:08:50 you can just apt-get install a kernel of choice... there's also a script that checks for the latest kernel within a series and does it for you Aug 21 13:08:56 that sounds like a smart idea Aug 21 13:09:42 bootloader... I just dd the two files to the right offset on the disk, but again there's presumably a script that does it for you Aug 21 13:10:27 I'm good with dd'img.. I should probably learn the offsets anyway Aug 21 13:10:48 sector 256 for MLO, sector 768 for u-boot.img Aug 21 13:11:53 Thanks Aug 21 13:12:51 they can be found at -> https://rcn-ee.com/repos/bootloader/am335x_boneblack/ Aug 21 13:14:36 Thanks again Aug 21 13:18:33 Will be a project for later this week when I have time to Play :) Aug 21 13:47:38 ds2: we're using the IMX6 ULL, specifically, the Variscite DART 6UL SoM Aug 21 13:47:51 thanks zmatt Aug 21 13:50:42 for? Aug 21 13:50:53 ah Aug 21 13:51:03 back on fri. Aug 21 13:51:17 yeah I saw in scrollback, had forgotten already again Aug 21 13:51:39 sure, i do the same thing all the time. Aug 21 13:52:43 are you doing ok? i've got a new dayjob - Garner Underground, Inc. we've been trying to bring up our own custom board that mates to the DART 6UL and having a hard time... Aug 21 13:53:44 doesn't the bbb and other related boards use a SD_Detect signal? Aug 21 13:53:50 from the sdcard cage? Aug 21 13:58:47 is the sd detect signal checked by the boot rom on the AM335x processor before attempting to initialize the sdcard interface and boot from sdcard? Aug 21 14:02:07 my quandary is this: if so, and if the sd detect signal can be pin muxed, then how could sd detect ever be placed anywhere other than the default pin mux for that pad/signal since the dts has not yet been loaded at processor boot rom execution time? Aug 21 14:04:39 zmatt: i'd be very interested to hear your thoughts on this. Aug 21 14:05:24 rom doesn't care about the card detect pin Aug 21 14:05:40 the card detect pin is only relevant for hotplugging cards Aug 21 14:05:59 "hotplugging" sdcards?!? Aug 21 14:06:04 never heard of such a thing! Aug 21 14:06:06 uhh, yes? Aug 21 14:06:12 that's how they're almost always used Aug 21 14:06:16 you stick a card into the slot Aug 21 14:06:23 you mean after a system is booted, then switchign cards? Aug 21 14:06:41 after a system has booted (not from sd card), inserting a card Aug 21 14:07:05 ah. Aug 21 14:07:39 the OS needs some way to know when a card is inserted so it can probe it, that's what card detect is for Aug 21 14:07:45 how do you know rom doesn't care about it when boot mode is configured to boot from sdcard? Aug 21 14:08:24 because it is documented which pins it uses, and because it has absolutely no reason to care, and because it supports eMMC/eSD where card detect doesn't exist Aug 21 14:09:00 i could see a conditional in boot rom code: "if (configuredToBootFromSDCARD && SDDetected) {bootFromSdCard();}" Aug 21 14:09:05 it just tries to access the card... if it's not there then it won't get any response Aug 21 14:09:59 (and after the command timeout it'll continue to try the next boot method) Aug 21 14:10:10 note that I'm describing TI's boot procedure, I know absolutely nothing about iMX Aug 21 14:10:17 sure Aug 21 14:10:21 but it will likely be similar Aug 21 14:12:20 where is it documented which pins are used? in the reference manual? Aug 21 14:12:29 yes Aug 21 14:12:49 i don't think imx6 is as complete, but i'll double check. thanks. Aug 21 14:13:17 at least I think it is Aug 21 14:13:27 yeah it is Aug 21 14:13:51 (section 26.1.8.5.8 of the am335x TRM) Aug 21 14:17:02 cool Aug 21 14:17:54 if a gpio on the am335x was set to output, and the output level was logic high, and that pin was tied to ground on the board, could that cause the am335x to get warm/hot? Aug 21 14:18:03 or vice-versa? Aug 21 14:18:32 so hot that u-boot was report "CPU is too hot to boot"? Aug 21 14:18:38 it sounds like a fine way to destroy an I/O Aug 21 14:18:39 s/was report/would report/ Aug 21 14:18:59 zmatt: yup, that's our intention! (LOL) Aug 21 14:19:41 what about getting warm/hot? Aug 21 14:20:08 recall we are bringing up a new board... Aug 21 14:20:33 if it doesn't cause any protection mechanism to trip then yes obviously it will get hot Aug 21 14:21:20 I think on the bbb it might just trip the pmic overcurrent protection Aug 21 14:21:22 i guess a question implicit in my question is, are there current-limiting mechanisms built into the gpios in the chip? Aug 21 14:21:42 hmm. hadn't thought of that. Aug 21 14:22:08 it depends on the drive strength of the I/O Aug 21 14:25:46 ok, thanks folks, expecially zmatt. logging off to reboot after an update. Aug 22 00:49:13 Heyy heyy Aug 22 00:50:12 I was wondering if anyone had any specific dimensions of the beagleboard black/green and just the base beagleboard as im creating a comparison guide for them against the Pi and Arduino Aug 22 00:54:23 all the beagleboard.org stuff has pretty extensive design documentation Aug 22 00:56:48 Guest9072: http://elinux.org/Beagleboard:BeagleBoneBlack Aug 22 01:49:25 I just need a link to tell me how to get from LXDE loaded on my stand alone BBB to the Cloude 9 IDE so that I can start some code. The BBB is STAND ALONE. No other computer attached. Thank you. **** ENDING LOGGING AT Tue Aug 22 03:00:00 2017
