Quartz64 Model-A 8GB board boot error

[CounterPillow]

The jumper should be in place, i.e. the "off" position.

Can you try booting a non-Android image? Try the pgwipeout CI image: https://gitlab.com/pgwipeout/quartz64_ci...s/download

Unzip it, flash rk3566-quartz64-a.dtb.img.xz, e.g. as follows (with /dev/sdx being whatever your SD card or eMMC module is.

Code:

sudo -i
cd /path/to/artifacts
xzcat rk3566-quartz64-a.dtb.img.xz > /dev/sdx

Once it finishes, try to boot it with UART attached. You should get an u-boot menu that allows you to boot a Debian installer. Just try booting into it, if it works we know the board's good. It's possible that whatever Android images you're using are not actually using recent enough firmware for the board. (It looks like memory training is failing?)
