Hi @szemzoa

I am trying to boot your kernel using U-Boot on MangoPi MQ-R (T113-S3), but without much luck:

U-Boot 2018.05 (Nov 06 2022 - 16:25:11 +0000) Allwinner Technology

Starting kernel ...

It hangs on Starting kernel.... No output on UART5 (0x02501400). Is there much of a difference between MangoPi MQ-Dual and MQ-R?

Anyway, I have compiled the kernel from @Evlers and changed uart0 status in dtb and it works like a charm!
