Hi Kever / Jagan,
I have Radxa N10 RK3399pro model B 6 GB ram, (4 GB +2GB NPU). When I tried to boot via micro sd card it booted with stock android u-boot, but this u-boot was not enabled all 4BG memory in total. So I tried to replace the image with the latest u-boot.
Now when I flash the u-boot to eMMC (onboard) with the latest u-boot it failed to boot. see below.
Please help me recover the board, I cannot reset the board via the reset button or nor is it entering the u-boot command prompt.
Please advise me on how to proceed.on recovery off the board?
Thanks -Anand
