Openocd Script to blink onboard LED

SVN R1888 Note: This is not the latest revision, but it is one that many folks use.

You must get the source from openocd from SVN

--->svn checkout svn://svn.berlios.de/openocd/trunk -r 1888

You will also have comment out line 16 of config.in

---># AC_CHECK_HEADERS(jtag_minidriver.h)

then run bootstrap.sh followed by

--->./configure --enable-ft2232-ftd2xx --enable-maintainer-mode

then make

followed by make install as root

I used Ubuntu 9.04 and had many of the essential tools already installed, you may need to install additional tools for your own dist

I had to add these specifically for openocd:

subversion (1.5.4dfsg1-1ubuntu2)

libtool (2.2.6a-1ubuntu1)

automake1.9 (1.9.6+nogfdl-3ubuntu2)

texinfo (4.11.dfsg.1-4)

See the readme.txt for additional info.

Once installed, you need to run openocd as root from the directory that contains the .cfg files and scripts you want to run.

Here are some useful scripts:

  • blinker.ocd
  • dump_apex.ocd
  • erase_check.ocd
  • flash_all.ocd
  • flash_apex.ocd
  • load_apex.ocd
  • probe_info.ocd

Here are the .cfg files for the hammer:

  • flyswatter.cfg
  • hammer.cfg

Invoke openocd like this:

-->openocd -f flyswatter.cfg -f hammer.cfg -f load_apex.ocd
