OpenOCD, a Free Software JTAG utility with ARM and MIPS support

JTAG adapter for parallel port

Just FYI, I've recently updated the OpenOCD Debian package in unstable. OpenOCD is a Free Software JTAG utility which currently supports quite a large number of JTAG adapters and various CPUs/targets (many ARM and now also some MIPS ones). It's being used by a number of Free Software related projects such as OpenMoko and many others.

Here's an example of how you usually use the (new) OpenOCD with a cheapo parallel port JTAG device. First, start the OpenOCD server, providing it an interface config file and a target config file (you can copy/adapt them from /usr/lib/openocd/{interface,target}/*.cfg, or use those files directly if they work for your target, of course).

  $ openocd -f parport.cfg -f lpc2148.cfg

Then, in another xterm for example, connect to the now-running OpenOCD telnet server. Here you can now run various commands to probe, control and program the JTAG device(s). Try help for a list of commands. As an example, for flashing a binary onto some LPC2148 eval board you would do something like this:

  $ telnet localhost 4444
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  Open On-Chip Debugger
  > reset init
  JTAG device found: 0x4f1f0f0f (Manufacturer: 0x787, Part: 0xf1f0, Version: 0x4)
  srst pulls trst - can not reset into halted mode. Issuing halt after reset.
  target state: halted
  target halted in Thumb state due to debug-request, current mode: Supervisor
  cpsr: 0x800000f3 pc: 0x7fffd2a2
  requesting target halt and executing a soft reset
  target state: halted
  target halted in ARM state due to debug-request, current mode: Supervisor
  cpsr: 0x800000d3 pc: 0x00000000
  > flash write_image /home/foo/program.bin 0
  wrote 1236 byte from file /home/foo/program.bin in 0.533683s (2.261701 kb/s)
  > resume 0

The final resume 0 will start to execute your program on the ARM LPC2148 microcontroller.

Check out the openocd info page (info openocd on the command line) for lots more documentation.

And now for some great techno/trance music from Code. The track is called "CCmixter.org" and is available from, uhm... ccmixter.org. Which is an awesome Creative Commons music remix site you should checkout if you don't already know it...
