Why does a FMC Memory swap for LCD on a F746 cause SPI pins to toggle when writing to 8 bit parallel LCD?

I was double checking SPI speeds and functionality and noticed SPI pins switching state when they shouldn't be. I narrowed it down and discovered this only happens when the memory swap for the FMC LCD is enabled. There are some other posts from me ...

When I enabled DWT (STM32F407), for getting microsecond delays, everything works fine but suddenly all activity comes to a stop for about 2 minutes and then everything starts working as usual. Interrupts seem to be occurring but everything else freezes.

This happens at randomly. Spent more than a month trying to figure out the issue and never suspected DWT. When I commented out DWT everything works fine now. Can someone educate me on why this is happening and how to avoid it? Thank you for your time...

"genlock" and the STM32H7 LTDC

I am trying to use the STM32H723 as a video output (tying the LTDC pins to an ADV7115 to convert them to HDMI). The idea is to read the bus traffic of an old 8-bit computer and generate the display from that traffic (as part of other duties). My conc...
