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:


 * [[media:blinker.ocd| Script to blink the user led]]
 * [[media:dump_apex.ocd| Script to dump apex from flash to file zxcv.bin]]
 * [[media:erase_check.ocd| Script to do an erase check on the flash (takes a while)]]
 * [[media:flash_all.ocd| Script to flash apex, zImage and rootfs]]
 * [[media:flash_apex.ocd| Script to flash apex.bin]]
 * [[media:load_apex.ocd| Script to load apex.bin to address 0x30008000 and verify it]]
 * [[media:probe_info.ocd| Script to do a flash probe followed by a flash info]]

Here are the .cfg files for the hammer:


 * [[media:flyswatter.cfg| Flyswatter Config for OpenOCD R1888]]
 * [[media:hammer1888.cfg| Hammer Config for OpenOCD R1888]]

Invoke openocd like this:

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