Is there any way to be able to step through the code (associated C Code) that is executed when calling "__main" from the start up file?
Reset_Handler PROC EXPORT Reset_Handler [WEAK] IMPORT HW_init IMPORT __main LDR R0, = HW_init ; Initialize board: FSMC, clock, etc... BLX R0 LDR R0, =__main BX R0 ENDP
The processor that is used as the target is the STM32F103ZE (Cortex-M3) and for some reason in a new spin of a board the system keeps on crashing in the "__main" code. It does not even get to "main()" function.
When the exception occurs I can track it down to the address of the instruction that causes this
0x080034B8 1B52 SUBS r2,r2,r5
, but I would need to analyze more assembly code to know what it is actually doing.
Is there anyway to get the "C Code" version of this code to step through?
Is there a document that explains what happens in "__main". I would imagine basic RAM memory initialization.
