Hi,
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 ?
Thanks.
Best regards,Vincent.#stm32f4-fmc
