I am using the STM32-Discovery board(ST-Link debugger chip connected via SWD interface (no JTAG) to STM32F100VB 32 bit CortexM3 processor) with uVision4(evaluation version, though code is way under the 32k limit).
I can look at memory & registers, and debug & set breakpoints in the disassembly window, but can't debug or set breakpoints in the regular source code windows.
I also can't program with uVision but this is not a problem. Just using the ST-Link utility program instead.
Does anyone know what would be causing this?
Thanks, Dusty
I am writing this for the ones who may encounter same problem.
You could forget to connect BOOT0 to GND. When it is left floating, MCU does not boot from flash.
