OpenOCD for IMote2 Wiggler

OpenOCD JTAG programming for IMote2 using pc parallel port Wiggler cable

Wiggler cable is generically available and can also be made easily. The below instructions are for [wiggler cable from Diy gadgets]. Instructions to make wiggler cable can be found [here].

Build OpenOCD

• check out OpenOCD svn repository

svn checkout http://svn.berlios.de/svnroot/repos/openocd/trunk openocd-svn

• build OpenOCD with parallel port wiggler

 cd openocd-svn
 ./bootstrap
 ./configure --enable-parport
 make

• install OpenOCD

 sudo make install
 sudo chmod 4755 /usr/local/bin/openocd
 sudo mkdir -p /usr/local/etc
 sudo cp arm-wiggler.cfg /usr/local/etc
 sudo chmod 755 /usr/local/etc/arm-wiggler.cfg

Get the arm-wiggler.cfg [here] This will install openocd to /usr/local/bin. Be sure this is on your PATH.

Program iMote2 with OpenOCD

• Connect iMote2 to the debug board.
• Connect JTAG interface to debug board and then connect to PC parallel port.
• Press the reset button on the iMote2.
• compile binary:

cd /opt/tinyos-2.x/apps/Blink
make intelmote2 install.100 openocd

Note that this will try to run "imote2-ocd-program-wiggler.py" with the executable as an argument. This program is assumed to be in $TOSROOT/tools/platforms/intelmote2/openocd/; The script can be found at [here]. Alternately, you can manually install the binary on the mote by running:

$TOSROOT/tools/platforms/intelmote2/openocd/imote2-ocd-program-wiggler.py build/intelmote2/main.exe

Manual programming method.

The above uses our custom "imote2-ocd-program-wiggler.py" program that is a wrapper for running openocd and programming the mote. You can also run openocd by hand:

 openocd -f /usr/local/etc/arm-wiggler.cfg

and then connect to it with:

 telnet localhost 3333

Various commands you can use:

halt
poll
reset
resume
