Hi,
I have a non-eMMC board I tried to boot from SD-card that doesn't work. I get no messages at all from the debug serial port either. The serial port cable is confirmed working on a board with eMMC.
The RKDevTool reports a MASKROM device.
Any help is welcome.

Thanks,

I actually managed to "fix" the problem by messing around with the RKDevTool. I tried to read chip info and changed storage just for the purpose of getting any response. Everything I did timed out. I pressed reset just for the sake of it and now it boots. I must have changed something in the MASKROM, unclear what (and what can you change in ROM anyway?)

Thanks,

Jan
