Posted on May 17, 2011 at 13:14During debugging my LED flasher using the STM FW library 2.0.3 GPIO functions, I found that when I UNcomment the
#define DEBUG 1
line in the stm32f10x_conf.h file (about line 28) to enable the debug code, my STM32F103VB throws a HardFault exception right at start-up before executing any ''debug'' code! Leaving this line commented out, removes the problem and everything works well.
Can anybody provide a solid reason for this??
I'm not comfortable with just ignoring the issue even though I don't need the debug code (yet?).
A few more notes on this:
1) The application size is quite small (only the GPIO code) and uses a fraction of the memory and storage.
2) Obviously, I removed the IDE's (Rowley's CrossStudio) ''debug switch''.
