Flashing a NanoPI M4 #33

Closed landersson closed 5 years ago

landersson commented 5 years ago

I'm trying to use this tool to update the kernel image on a NanoPI M4 (RK 3399). I can enter maskrom mode by pulling out the eMMC card, and the device is detected by rkdeveloptool:

kdeveloptool:>./rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x330c,LocationID=102    Maskrom

All other commands seem to fail though:

./rkdeveloptool rd 3
Reset Device failed!

./rkdeveloptool rl 0xe000 1000 out.bin
Read LBA failed!

Any idea why this isn't working?

Entering maskrom mode via the "rockusb" command rather than by pulling out the eMMC card fixes the problem for me.
