Hi
Chip:stm32h723
Peripheral:FMC
Configuration:FMC_NORSRAM_DEVICE , FMC_NORSRAM_EXTENDED_DEVICE;
FMC_ACCESS_MODE_A
FMC_ASYNCRONOUS_WAIT_ENABLE
If the extended device(eg. FPGA) do not assert NWAIT,the program on stm32h723 will crash. I want to know which register can set the timeout for the NWAIT signal to prevent a crash?
Best regards,
Andy Zhou

Hello,
Unfortunately, there is no way to recover from that situation except to reset the CPU for example using the watchdog.
