Problem with device tree
A message that is not in the archive (sent off-list or not yet received): [email protected]
Hi Don,
You use a (recent) mainline kernel with configurations that seem to be vendor specific; your U-Boot is not configured correctly; see comments below.
I found a more detailed training document, it uses 6.1.y kernel: https://bootlin.com/doc/training/embedded-linux-bbb/embedded-linux-bbb-labs.pdf

My apologies, I tried using
omap2plus_defconfigas the tutorial suggested but got errors so I changed and the output I put in pastebin is usingbeagleboard_defconfig. I still get errors though.
This is an excerpt from your (buildroot) defconfig:
Quoted 1 line
BR2_LINUX_KERNEL_DEFCONFIG="beaglebone_defconfig"
^^^
This defconfig does not exist in the mainline kernel. Either supply the missing file, or use the architecture default.
Quoted 2 lines
BR2_LINUX_KERNEL_DTS_SUPPORT=y BR2_LINUX_KERNEL_INTREE_DTS_NAME="https://elixir.bootlin.com/linux/v6.6/source/arch/arm/boot/dts/ti/omap/am335x-boneblack.dts"
This must be an in-tree name, not a download from the internet. 'ti/omap/am335x-boneblack.dts' should goe here.
Quoted 1 line
BR2_LINUX_KERNEL_CUSTOM_DTS_PATH="arch/arm/boot/dts/ti/omap/am335x-boneblack.dts"
Not needed, delete this
Quoted 4 lines
BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y
BR2_TARGET_UBOOT=y
BR2_TARGET_UBOOT_USE_CUSTOM_CONFIG=y BR2_TARGET_UBOOT_CUSTOM_CONFIG_FILE="/home/don/buildroot/buildroot-2024.02.1/configs/beaglebone_defconfig"
This is a buildroot defconfig, U-Boot cannot use it. Buildroot uses (in-tree) TARGET_UBOOT_BOARD_DEFCONFIG="am335x_evm" for the Beaglebone.

Have a Blessed day!
Don
Kind regards,
