Hey, I use the nanopiR4S but can't get it to boot from its official image (rk3399-sd-friendlywrt-21.02-20220803.img.gz) I am unzipping the .gz, there is a single .img that I flash on my sdcard. After that my sd card has multiple partitions. I insert it into my R4S but the stat LED is blinking only... no system boot.
