I just bought this kit: https://shop.allnetchina.cn/collections/sata-hat/products/quad-sata-hat-case-for-raspberry-pi-4 but with a rock-pi 4c+ because currently there are no RPis available.
I followed this guide.
Unfortunately, I have an issue with starting the service and currently I am not sure where to proceed 
this is my /boot/armbianEnv
