dhanar10 can you please test if adding #CONFIG_SYS_RELOC_GD_ENV_ADDR is not set to projects/Allwinner/bootloader/config and test with U-Boot 2020.01?
I have just tried you suggestion but Orange Pi One still fail to boot. It still stops at "starting kernel". The serial console log is attached (i have removed "quiet" from extlinux.conf). There seems to be no additional info compared from our previous attempts. dejan_ natumbri maybe you can verify if my testing result is correct when you have the time.
jernej Tell me if you have other ideas that we can try to resolve this issue. I have not given up yet :D.
