I 've owned rockpi s for a month.
I rebuilded uboot using github resources(u-boot-next-dev) . And this procedure generated uboot.img,trust.img, rk3308_loader_v1.31.127.bin , it failed using AndroidTool_Release_v2.71 tool to download these files.
check log, founds:ERROR:PrepareIDB–>No Found 1st Flash CS.
How to solve this p?
