Precompiled kernel fails to boot

[FerGT50]

Hello, it's me again :D

I follow your suggestion and tried to boot your precompiled kernel (https://github.com/hexdump0815/linux-mainline-and-mali-allwinner-h6-kernel/releases/download/5.11.0-rc1-stb-616%2B/5.11.0-rc1-stb-616+.tar.gz)

Unfortunately, it fails booting from microSD; it then tries to boot from network, which fails as well since I don't have the needed infrastructure.

Any hint about what could be wrong?

The log (copied from serial console):

u-boot sees the mmc, but cannot find the dtb: "Failed to load '/boot/dtb/allwinner/sun50i-h616-orangepi-zero2.dtb'" - this is why it will not continue to boot i guess ... maybe check the filesystem if the dtb is really there ...

Good catch. I just decompressed your .tar.gz; looks like you packed /boot/dtb/sun50i-h616-orangepi-zero2.dtb etc., without the "allwinner" intermediate folder. I moved the DTBs and now it boots OK on Armbian unstable, thanks for your support!
