I'm working on a STM32H753 (with EVAL2 eval board) on which I have connected an external QSPI Flash.
Right now the CPU is @ 400MHz, the QSPI is configured in single IO (SPI) @ 12.5Mhz.
I can erase, program and read the Flash in indirect mode, then read it in memory mapped mode (from my software).
However when I try to read the Flash in memory mapped mode from the debugger I have some errors. They don't look random, there is a clear pattern (as you have guessed the flash is programmed with successive values from àx00 to 0xFF):
Any idea ?
