I am running version Keil 4.73 and writing code for a STM32F302. I am running through an issue where when using the debugger I am unable to exit the file "staurtup_stm32f302xc.s". If I flash the controller its fine(I have a CAN section and see data transmitted when not in debug mode).
When I click on the debug icon, the application open up at "LDR R0, =SystemInit" (Normally it start at the first line of Main())in the "staurtup_stm32f302xc.s" and will step down to "BX R0"and will stay there forever.
Sometimes if I move my code around a little(I don't delete only move) it will work for a while. Then I make a change and I am locked into the start up file again.
Thanks for any help.
I had similar expirience. Try to disable all of your breakpoints; that happens if there are to many of them.
Thanks, it looks like you solved my problem.
