**** BEGIN LOGGING AT Sat Nov 13 02:59:57 2021 Nov 13 03:46:37 Not one single person laughed or chuckled a bit? Sheesh, tough crowd. Nov 13 16:03:39 where can I find the description of the identification eeprom content on beaglebone-ai? The original patches and my board has name=BBBBAI__, but what got applied to mainline uboot uses name=BBONE-AI? Nov 13 16:15:26 Jacmet, there is no eeprom, it's in the first sector of the boot0 Nov 13 16:16:06 Grab's new bbai, lets' see what it should be..

Nov 13 17:55:27 i don't believe A2 shipped to market yet.. Nov 13 17:55:58 ping @jkridner ^ Nov 13 17:56:04 ahh, I don't see any clear revision markings on the baord Nov 13 17:56:06 root@beaglebone:~# hexdump -C /dev/mmcblk1boot1 Nov 13 17:56:06 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| Nov 13 17:56:06 * Nov 13 17:56:06 00400000 Nov 13 17:56:57 Jacmet, A1 does have a label between heatsink and Kingston eMMC. Nov 13 17:57:23 BeagleBone AI Rev A1 Nov 13 17:57:43 rcn-ee: mine doesn't even have a heatsink Nov 13 17:57:49 so it gets pretty toasty Nov 13 17:58:12 rcn-ee: I believe it was an early board Jason sent me Nov 13 17:58:41 ah, yeah... A2's eeprom needs ot be sent to u-boot, i haven't done that yet.. the eth mac needs to be figured out too.. Nov 13 17:59:47 ps get a heatsink on there asap.. here's the dimennsions (same one used on the x15) https://www.digikey.com/en/products/detail/cts-thermal-management-products/BDN10-3CB-A01/272736 Nov 13 18:00:13 rcn-ee: I will Nov 13 18:01:08 rcn-ee: We've used the initial patches in Buildroot since I added the board, and I wanted to migrate to mainline u-boot/Linux now, but noticed that u-boot doesn't detect it as a bb-ai Nov 13 18:01:59 rcn-ee: E.G. https://git.buildroot.net/buildroot/tree/board/beagleboneai/patches/uboot/0001-BeagleBone-AI-support.patch Nov 13 18:03:34 rcn-ee: but I don't quite get it then. This is on top of u-boot 2019.04, so without the workaround to read board id from the emmc (commit d6eaaae3d3) Nov 13 18:03:36 Jacmet, i'm currently shipping this branch for BeagleBoard.org: https://github.com/beagleboard/u-boot/commits/v2021.04-bbb.io-am57xx Nov 13 18:03:57 it doesn't include A2, but it's much closer to mainline.. Nov 13 18:04:58 Jacmet, this little if failed change should boot the A2.. https://github.com/beagleboard/u-boot/commit/702ea30b462ba06f4fbee3393f0e6c19531f1e5f#diff-416550426600a1b4d36d11880563cde794e2a884b47bf796db8880747b8ad129 Nov 13 18:05:21 if (rc) Nov 13 18:05:21 if (rc) { Nov 13 18:05:21 printf("ti_i2c_eeprom_init failed %d\n", rc); Nov 13 18:05:21 ti_i2c_eeprom_am_set("BBONE-AI", "A"); Nov 13 18:05:21 }; Nov 13 18:06:44 ahh Nov 13 18:07:10 v2021.07 should get built-in extension support the team at bootlin did for BeagleBoard.org Nov 13 18:07:24 and in the 2019.04 patch it was ti_i2c_eeprom_am_set("BBBBAI__", "A"); Nov 13 18:07:42 there we go! nuke change that to my fix... Nov 13 18:07:48 that kind of explains why I had issues getting 2021.10 booting without hardcoding bbai detection Nov 13 18:09:30 Jacmet, ps, can you do a dump of the eeprom? Ps feel free to add the value to mainline u-boot... At some point the A2 should become the default.. Nov 13 18:09:33 rcn-ee: ok, so either hardcode bbone-ai if it failed to read the eeprom or stick eeprom data in the emmc boot partition? Nov 13 18:10:04 rcn-ee: I guess I don't have an eeprom after all, just the fallback code to ti_i2c_eeprom_am_set("BBBBAI__", "A"); Nov 13 18:10:06 Correct, on the AI, we should read eMMC, if fail read eeprom, if fail just default to the BBAI for us.. Nov 13 18:10:58 the bbai is the only am57xx from us or TI without eeprom, so it's safe to assume.. Nov 13 18:11:11 rcn-ee: ok, good. Sorry, got confused by seeing (broken) bbai support in mainline Nov 13 18:11:27 3rd party did the bbai, we didn't catch the eeprom miss till it was way way too late.. Nov 13 18:11:37 (pcb) Nov 13 21:47:08 This seems like a more promising spot to ask... I have a Beaglebone Black that gives a 100% consistent error found here on boot: http://0x0.st/-RqQ.txt (this is just grepping CPSW from the journal after pulling the card out) Nov 13 21:47:23 This is with the latest archlinux-arm image Nov 13 21:47:43 Said SD card works fine, seemingly, in my other BBB Nov 13 21:47:47 both are rev B6 Nov 13 21:47:58 Is this confirmed hw failure? is there anything else to do? Nov 13 21:50:39 Note that this is not the blah blah blah nothing at MDIO addr 0 *finds something at 2* error, but I don't know if the kernel would print it the same way anymore so maybe it -is- that reset bug Nov 13 21:52:22 ...That wording is confusing, all I mean to say is the error message is different from reports of that I've seen **** BEGIN LOGGING AT Sun Nov 14 06:02:15 2021 Nov 14 16:28:06 remind me to ssh to the BBB over ethernet do I need to do anything on the PC side Nov 14 16:28:33 just moved over to debian 11 on my box and i forgot to take a peak at how I had the ethernet connections set up Nov 14 18:41:48 electroni Nov 15 02:36:30 GenTooMan: Things are on hold for now. The Cape has no components to be placed on it. Boo! Nov 15 02:36:47 They need to dig into the sand more. Sheesh. Nov 15 02:37:55 I found a mfg. but their PCB and assembly mfg. is held up by their lack of components. They are outsourcing to me for components. Blah. Nov 15 02:38:00 I have to look around... Nov 15 02:39:19 I contacted DigiKey and I will have to reach out to other stock merchandisers. Nov 15 02:39:26 Argh... Nov 15 02:40:22 You know something, if it is not one thing...it is two, three, four things * infinity. Blah. Nov 15 02:43:18 I feel like that child that could not get his candy on trick or treat day. Nov 15 02:45:33 Deme el ducle! Nov 15 02:46:04 switch the c w/ the l and that is give me my sweets in Spanish. Nov 15 02:46:59 I am so close. Seriously. I can smell the etching and placements! **** ENDING LOGGING AT Mon Nov 15 02:59:57 2021
