NUCLEO-H745ZI-Q doesn't runs my program

[ADe C.2]

Hello,

I've ordered two NUCLEO-H745ZI-Q at a same distributor, on a same time.

It seems that one CPU's board is "bricked" :

The software runs fine on a board. the same software literally doesn't run on the second board.

The embedded debugger tells that CPU is well detected, and programmed.

I have no idea, i saw some post which advised a problem with the CM7.

A simple LED blinking doesn't works at all.

I tried to force BOOT_0 with 3.3V, it blinks the red led LD3.

I tried a full memory erase, then reprogrammed, but still no effect.

Any idea ?

Regards

Alexandre

Compare option bits.

BOOT0 should generally be low to run user code.

Debug it, see where the code gets stuck.

Hello,

Thanks @TDK, to your answer.

The problem is solved, no bricked CPU. The problem was that my CubeProgrammer doesn't erase correctly the device.

I switch computer, and the problem is solved.

Regards.
