I found the FAT32 partition that Emmanuel mentioned:
" just make sure to put it on the FAT32 partition in
dts/allwinner as we need it loaded by u-boot and it can't read ufs."
So after copying the overlays and allwinner files to=20
/boot/msdos/dtb/overlays and /boot/msdos/dtb/allwinner I have at least=20
some error messages:

Even with uart2 and uart4 enabled in: sun50i-a64-pine64.dtb I still=20
don't see anything outside of uart0 under dmesg.
What else could I try at this stage?
