But now when I looked into the rockchips' boot sequence, it doesn't look as optimistic as I thought. because USB OTG interface is tried at the end if nothing succeeded, oppositely to what I thought. Fortunately, for rk3328, but NOT for rk3399, ROM code tries eMMC first. So preparing a properly flashed eMMC module could save your board. If the problem is in the partially working/screwed up SPI NOR flash code.
For rk3399, spi is checked before eMMC and SD which is uh oh. because it can brick the board.
Forget about the rkdevtools, in short, :lol: use an eMMC module. if that doesn't work (but don't be hasty). that means the problem is not in SPI NOR flash.


Thanks for all the suggestions.

The top USB on the board is the OTG one.
I don't think I can try that eMMC port as I don't have a eMMC drive.

Looks the board is pretty well bricked already so the next step is towards the rubbish bin. :-)


Thanks for your time.
