Two NUCLEO-H755ZI-Q boards acting differently

SoCalJim · ‎2025-01-29

I have two NUCLEO-H755ZI-Q boards and I’m trying to run the SPI_FullDuplex_ComIT example on both.

One board breaks here (whether the software is built for master or slave):

The other board has no problem (whether the software is built for master or slave).

Any ideas?
