hey @jock, sorry I've been away for looong while.
So as per our last discussion I tried to update the uboot and now I have a soft brick (can access uboot, but can't boot).
The story:
1) grabbed multitool, wrote via balena and added Armbian_22.11.0-trunk_Xt-q8l-v10_sid_edge_5.19.12_xfce_desktop to images
2) erased nand and flashed the said image
3) I was not sure if the image contained the uboot or not so I dd-ed the uboot from sd to nand:
dd if=/dev/mmcblk0 of=/dev/mmcblk2 bs=32k seek=1 skip=1 count=40
The status:
1) uboot is 2022.04-armbian
2) booting from multitool(which worked before), mmc1 (sdcard's device id from uboot) I get to "Starting kernel...." screen has no signal, screen turns on, black screen, no image
3) booting from mmc0 (nand's device id from uboot) says it can't configure the voltage and fails, then tries to boot from network.
any advice ?
