I have an STM32F446 + external PSRAM.
Everything's working fine, but it seems that I have a bug in my software that sometimes (hard to reproduce) breaks the connection between the STM32 and PSRAM.
When it is the case, I cannot access the PSRAM anymore, and trying to do so with the debugger says "Error, CPU cannot read ..."
So I would say that the FMC stopped working.
Is there any "error" bit or "fault bit" somewhere that could help me finding the reason ?
Any easy way to restart FMC ?
