Buildroot configs for pocketbeagle with lastest Linux kernel version and with all pocketbeagle's hardware support?

[Siegurd01]

The PocketBeagle board with official Debian image boot's in about 2 minutes. That's quite long for Embedded purposes so I was looking for some Embedded Linux for PocketBeagle. Buildroot is the case, but unfortunately all instructions and repo's are about 4 years old and uses Linux/arm 4.14.18 Kernel witch is quite old and does not support lots of features and hardware.
I was success on booting the board with some fixes and patches using this instruction (all booting time took 9 seconds, which is nice), but still after the boot complete in /dev folder only few devices are present (no SPI, PRU, USB and so on). Then I tried copy some board configs from beagleboard repo and build with new kernel, but lots of errors occurs on building step. After spending 4 days trying different cases/configs and settings I give-up)
It would be nice to create buildroot PocketBeagle board config files for embedded proposes that include all SBC hardware devices integration and initialization so it could be a good starting point for developers. I can help with testing and writing the instruction cuz my Linux editing knowledge are far from required level.

@Siegurd01 what's wrong with? https://github.com/buildroot/buildroot/blob/master/configs/beaglebone_defconfig

[Siegurd01]

@RobertCNelson Thanks for quick answer! I tried some old beaglebone_defconfig and board stuck at uboot stage with endless timer error. I will try suggested defconfig by you and reply.

[RobertCNelson]

PS, you'll need to add teh PocketBeagle *.dtb to:

https://github.com/buildroot/buildroot/blob/master/configs/beaglebone_defconfig#L26

BR2_LINUX_KERNEL_INTREE_DTS_NAME="am335x-evm am335x-bone am335x-boneblack am335x-bonegreen am335x-evmsk am335x-boneblue"

PS, if you change:

BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION="$(call github,beagleboard,linux,5.10.30-ti-r3)/linux-5.10.30-ti-r3.tar.gz"

to:

BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION="$(call github,beagleboard,linux,5.10.65-ti-r30)/linux-5.10.65-ti-r30.tar.gz"

and

BR2_LINUX_KERNEL_DEFCONFIG="omap2plus"

to:

BR2_LINUX_KERNEL_DEFCONFIG="bb.org_defconfig "

and you'll have all the latest fixes, along with the kichen sink config..

Regards,

[Siegurd01]

Should I add "am335x-pocketbeagle" to

BR2_LINUX_KERNEL_INTREE_DTS_NAME="am335x-evm am335x-bone am335x-boneblack am335x-bonegreen am335x-evmsk am335x-boneblue"

and then "am335x-pocketbeagle.dtb" to:
https://github.com/buildroot/buildroot/blob/master/board/beaglebone/genimage.cfg
?
A file am335x-pocketbeagle.dtb i can add from PocketBeagle's SD card with Debian?

[RobertCNelson]

Correct!

[Siegurd01]

not sure about this line:
https://github.com/buildroot/buildroot/blob/aaf7b2c9c6847c487af46e023dae3497efdd652f/board/beaglebone/uEnv.txt#L9
Does name of a board correspond to Pocketbeagle and is the root path to SD card correct?

[RobertCNelson]

looks like a broken eeprom, nuke it..

bb.org_defconfig_defconfig

sorry, didn't relize it appended..

use
bb.org

[Siegurd01]

for quick hack i chose axm55xx_defconfig just to check if compilation reached the end. And its finally does. Trying to boot.
..
nope:

it selected the right one..

[Siegurd01]

The 4 years old uEnv.txt (it worked with old kernel):

Same results.

[Siegurd01]

Maybe this is the reason

I tried just copy uboot files to SD from old buildroot repo and board boot's but stuck on:

Will try the uboot settings from https://github.com/beagleboard/buildroot/blob/beagle-tester/configs/pocketbeagle_defconfig
Nope...

[Siegurd01]

SD uboot Deb.zip
OK! I just relapsed all files in SDcard boot partition with official Debian image boot files and all things now working. The board boot's in to login prompt!
BR2_LINUX_KERNEL_DEFCONFIG="aspeed_g4" was set for quick building. Will now try with:
BR2_LINUX_KERNEL_DEFCONFIG="bb.org"

[RobertCNelson]

buildroot should have a rootfs.img or something, anyways use their recommend partition layout..

[Siegurd01]

@RobertCNelson, what _defconfig is using for official beagle Debian uboot build? I want to try integrate it in buildroot and create an instruction for all.

[RobertCNelson]

This branch:

https://github.com/beagleboard/u-boot/tree/v2021.10-bbb.io-am335x

This config:

am335x_evm_defconfig

Regards,

[Siegurd01]

Me again.

@RobertCNelson, I have some progress. Board is now booting in to a login prompt. No manually copying files to SDcard needed.

The setup is:

1. buildroot-2021.11-rc3
2. buildroot pocketbeagle config files.zip it contains all necessary board and config files (it took me lot of days to assemble all of files and configs together to make it even boot :) ).
3. I could not integrate https://github.com/beagleboard/u-boot/tree/v2021.10-bbb.io-am335x cuz I haven't found the way to set the tree path in buildroot defconfig (it should be like BR2_TARGET_UBOOT_CUSTOM_REPO_?tree?= ... ? )

Anyway after success build and login, I found that the /dev folder is quite empty (no spi, ttyUSB* (sim7600 modem) and maybe others devices found).
After i type:

mount -o remount,rw /
depmod
modprobe option

SPI and ttyUSB* are now present, but it's feels like a very dirty hack and I'm not sure every device will work properly so I want to please you, if its possible, to check config files and pocketbeagle's board folder so the instruction on how to create a properly working board by hardware only ( the software should be on user responsibility by make linux-config) could be made.

PS. : There are some errors on boot with tells that atleast uboot is configured in unproper way (by edditing techlab files).
