Preparation

• Build a toolchain. See Crosstool-ng, and use the arm-bare_newlib_cortex_m3_nommu-eabi config.
• Build OpenOCD

Environment

export PATH=${TOOLCHAIN_DIR}/bin:${PATH}
export CROSS_COMPILE=arm-bare_newlib_cortex_m3_nommu-eabi-

Using TI's StellarisWare and Samples

• Download from: http://www.ti.com/tool/sw-lm3s (or look for an update / new page)
• Extract the contents of the windows executable.

mkdir sw
cd sw
unzip ../SW-*.exe
rm ../SW-*.exe

• Edit the PREFIX variable in makedefs. E.g:

PREFIX=${shell echo -n ${CROSS_COMPILE} | rev | cut -b 2- | rev}

• Build:
  • You make need to remove the build sections that target the Cortex-M4 from the following files:
    • ./driverlib/Makefile
    • ./grlib/Makefile
    • ./usblib/Makefile
  • The entire source tree won't build, due to Cortex-M4 boards, at this point, move into your board specific directory, and continue from there.

Flashing with OpenOCD

You may need the stellaris.cfg file from here http://gitorious.org/openocd/openocd/blobs/master/tcl/target/stellaris.cfg
