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...

Awesome! Thanks for taking the time and giving such a thorough answer. I will test this later today or at the latest tomorrow - I will send an update with my findings!

Your two points on the S-Port seems to explain my trouble @Community member. Thanks a lot! I guess there is not much I can do about this penalization. :) I suppose I could try to do the physical remap of SRAM1 as this seemed to increase performance ...

Hey @Community member,thanks a lot for your quick response and for your answer! I thought the same thing about debugging. That's why I also executed binaries, that returned the cycle-count of the binary- sadly it didn't change anything about this cy...
