nandFlash via FSMC + interrupts

Question asked by jakubowski.krzys.001 on Jan 18, 2018

Hello, I'am using STM32F746IG and I have a problem with writing data to the Nand Flash memory via the FSMC . When I generate a project with CubeMx, configuring only the flash memory, everything works, i.e. writing, reading, erasing, reading ID etc. The problem starts when I add TIMER to the project (or anything that generates an interrupt), then in the pages appears mistakes. Could this look like a connection to the __DSB barrier? What happens when __DSB is executing and the interrupt call?
