I am trying to build mainline atf, u-boot, and arch on this board.
i built atf (bl31.elf), u-boot with rkbin’s (rk3568_ddr_1560MHz_v1.21.bin), and got the rootfs arch from https://archlinuxarm.org/platforms/armv8/generic.
I flashed u-boot-rockchip-spi.bin to SPI on the board.
I created a gtp partition table on the emmc with 1 ext4 partition and extracted the arch image to the ext4 drive (sudo bsdtar -xpf "ArchLinuxARM-aarch64-latest.tar.gz" -C "whereimountemmc"). I created this file with these contents
/boot/extlinux/extlinux.conf
menu title Select kernel timeout 100 label Arch kernel /boot/Image initrd /boot/initramfs-linux.img devicetree /boot/dtbs/rockchip/rk3568-rock-3a.dtb append console=ttyS0,115200 console=tty1 rw root=UUID=df42bbe6-9be9-483c-b56b-9bccbf67a65f
And then booted the board and I get this output

Those last 2 lines seem to be the problem. Does this suggest a ram memory problem? I can’t find any info on the internet about this issue or how to fix it.
U-boot can find the menu config, it can find the kernel, and when it tries to load the kernel I get this problem. The kernel does not continue past these 2 errors after waiting 30 minutes. Arch says it this kernel is built to support the device trees provided in /boot/dtbs. Nothing was changed in the rootfs except the extlinux.conf.
Anybody got an idea on what to do? Thanks
And if I’m able to get this working I can provide all the steps needed to get a full mainline vanilla Arch linux install running.
EDIT : After rebuilding u-boot without modifications (had made some for display but didn’t work) I get this error instead
