Resolved! Weird cycle behavior when running code from SRAM. 4 cycles per instruction instead of 1. What could be the cause?

Board: Nucleo-144Chip: STM32L4R5ZIT6PHey all!I have a curios problem when executing code from SRAM. My firmware lies in flash and occasionally jumps to a externally loaded binary in SRAM. As the cycle count of this binary is quite crucial, I used the...

Timer3 update event interrupt not working properly.

I'm just starting to learn how to program ARM microcontrollers using ST's HAL. So I have this code which generates a 1khz and 20khz signal using a timer in output compare mode. That all works well and I tested it with a scope and it's as expected. Th...
