Yesterday I tried to find the JTAG pins on the board with my multimeter, and while I do not have a programmer yet (I might be getting a bus pirate by the end of the week) I wanted to test my luck with the tools that I had in mind.

I was well aware that some devices use their own weird proprietary connectors for the JTAG pins, but I after taking a look at the three different headers right next to the serial port, I figured there was a good chance it was using a standard pinout. And I might be right.

I found out about the TI 14 Pin JTAG connector, and after looking at the placements of the GND and VCC pins, we might just have a winner in your hands:

I might be wrong of course, but that wont stop me from trying those pins out as soon as I get a proper programmer in my hands.
