STM32 GDB / OpenOCD Commands and Initialization for Flash and Ram Debugging

initializing OpenOCD I used the following command in Eclipse (The board config file references the stm32 mcu and was found in the OpenOCD installation as an example): "openocd -f interface/olimex-arm-usb-ocd-h.cfg -f board/stm32f10x_128k_eval.cfg". When I run this within Eclipse everything appears

exception handling code in binary from pure C code

Hi, I tried out yagarto to generate code for a cortex-M3 (STM32). I got it working, but I was surprised a whole bunch of exception handling code ends up in my binary (the source code is pure C) This happens both with my (complex) program, and the STM3210ETest small example project (yagarto howto page, STM32), if I add this small function: [c] unsigned long long xyz(unsigned long a, unsigned long long b ) { return a/b; } [/c] If i check the library, there are some .ARM.extab/.ARM.exidx sections

You cannot do that as part of a class. I don't know the STM32, but my guess is that interrupt vectors are known by their global name, so they cannot be established using C++ name mangling. This also implies they cannot be hidden with in a class (class members

How to stop breaking at reset

I am developing a number of projects for STM32 processors using Eclipse, gcc, gdb and an Olimex ARM-USB-OCD jTag dongle. All works well, but every time I relaunch the project in debug mode the code stops at address 0x08000000. The debug window

this always happens. Furthermore I suspect it is using up one of the 6 breakpoints provided by the STM32, which restricts debugging. I launch gdb with the following commands: target remote localhost:3333 monitor reset init load monitor reset init break main The first breakpoint it should
