Posted on September 07, 2015 at 11:34Hello, I have some problems with FMC when I try to port my code from SMT32F407(with FSMC interface) to new project based on STM32F746(with FMC). The only changes I've made are timings(adapted to 216 MHz clock) an...

Posted on September 11, 2015 at 11:31You were right. It looks like FMC address region belongs to 'External RAM', thus it is cacheable by default. I solved problem by adding MPU region that covers NOR memory address, here is the code: http://pastebin...

Posted on September 08, 2015 at 13:24Thank you for response Syrine. I've read this application note and I can see no difference between FMC and FSMC when it comes to NOR flash. My init code is strongly based on example from cube package that you've ...
