Ok. You are aware of that wiki page, are you?:
https://rhombus-tech.net/allwinner_a10/Buildroot_Toolchain/

Once you have the toolchain running and a copy of legacy sunxi u-boot
make sure to checkout this tag:
git checkout v2013.07-sunxi.4

make sure to change the boards.cfg (MMC_SUNXI_SLOT=2), and write sunxi U-Boot to SD-Card with the commands described after v2013.07 or earlier. This were the steps I had to take to boot a sunxi 3.4 kernel and a Debian rootfs in 2020.
I have documented this here:
https://rhombus-tech.net/allwinner/a20/EOMA68-A20_2-7-4_preproduction/
(Section Sunxi U-Boot (legacy))

If it helps, i could upload a copy of sunxi-spl.bin and u-boot.bin for
you.

Ok, I'll have a look at your image.
