**** BEGIN LOGGING AT Sat Dec 03 02:59:57 2022 Dec 03 07:09:47 I am trying to build a minimum image for BBB using the instructions at https://elinux.org/Building_for_BeagleBone Dec 03 07:10:04 I cant get uboot to load my kernel Dec 03 07:11:13 Hit any key to stop autoboot: 0 Dec 03 07:11:14 ** Invalid partition 2 ** Dec 03 07:11:14 switch to partitions #0, OK Dec 03 07:11:15 mmc0 is current device Dec 03 07:11:15 Scanning mmc 0:1...

Dec 03 07:14:23 i suspect that as well Dec 03 07:14:37 do we have to patch u-boot for BBB Dec 03 07:15:53 the elinux wiki article uses the u-boot code at git://git.denx.de/u-boot.git Dec 03 07:15:55 i know the beagleboard.org images tended to carry patches, but i also used more-or-less mainline u-boot for the most part Dec 03 07:19:57 it should not look for EFI isnt it? Dec 03 07:20:55 mainline u-boot has an EFI implementation Dec 03 07:28:16 ok Dec 03 07:31:49 i have a strange problem in my board pressing BOOT switch and connecting the power dosent boot from SD Dec 03 07:32:21 I have to let it boot into eMMC power down and then press the power button together with BOOT button Dec 03 07:32:32 sometimes reset + BOOT works too Dec 03 07:32:55 the behavior is not consistant Dec 03 07:34:36 you have to hold the boot button down while it's booting Dec 03 07:34:37 when this problem occurs the power led lights up but non of the other leds Dec 03 07:35:04 oh so what you mean is that i have to first connect power then hold the BOOT button Dec 03 07:35:18 i was holding the boot button down and then connecting power Dec 03 07:35:56 the latter could work, but i think you need to hold it for a second or two ... it has been years since i've had to do that so a bit foggy on details Dec 03 07:36:20 there's a window of time where it needs to be pressed ... Dec 03 07:37:24 i kept holding it forever Dec 03 07:37:43 when this problem happens the power indicator lights up but nothing on the serial console Dec 03 07:40:46 * vagrantc shrugs Dec 03 07:40:50 it is a bit finicky Dec 03 07:41:17 i recall having to use a ballpoint pen to get the right pressure in the right spot **** ENDING LOGGING AT Sun Dec 04 02:59:56 2022
