NUCLEO-H7S3L8 debug problems

[Domi]

Hello,

Started to dwell info embedded development and got my hands on a NUCLEO-H7S3L8 development board. Firstly wanted to analyze the example code that comes with the development board and modify it a bit. But when started to debug, it seems to stop at I and D cache enable functions, and example LED blinking disappeared. Has anyone encountered something similar and could help to fix this problem?

Only change I made to the example code is set-up a PC8 as a PWM to drive a LED switch.

Additionally, tried a mass erase and re-flashing, but still nothing, the problems remains the same as I mentioned.

If you're trying to single-step thru these functions with debugger - just don't. Put a breakpoint outside and run thru these functions at full speed. It is a known issue. Or do you see a different problem?

Hello @Domi 

Did the original project without your modification work well in debug mode?

Could you precise the name of the example your debugging?
