I make a new RA2E2 hardware board. But it can’t start up flash programmer connect fail with SCI, and SWD connect fail too.
I check some pins
P201/ MD can switch 0V or 3.3 V with key.
RES can switch 0 V or3.3 V with key.
timing is right when PC send data to RA2E2 board.
But RA2E2 have no any response.
Are there any other debug way for RA2E2? or any user guide doc for this issue?
