Hi Chris, I'm work with stellaris too, using GNU tools. I work in one of two ways (both the use but for different situations): - To degub applications, take the elf file generated by gcc and use gdb to program and debug throw openocd. In this case use "remote target" to conect from gdb to openocd in a lan enviroment. More specifically, use a PC with linux conected to microcontroller using JTAG, and debug from Windows using eclipse in other PC. This mode is somewhat complicated to configure, but works very well. - To write a release firmware, build the proyect whitout debug information (remove any "-g" option to compile and use -O2). Take the elf file and convert them to bin using objcopy:
objcopy-arm-none-eabi -O binary firmware.elf firmware.bin Then write firmware.bin from console using OpenOCD: openocd -f path_to_config/openocd.cfg -c init -c"reset halt" -c "flash write_image erase path_to_file/firmware.bin" -c "reset" -c "shutdown" Obviously, this way is simpler. I don't use SWD interface, I just have a "home build" jtag, but if OpenOCD detect the target, I think should have no problem. Good luck!
