openocd 0.5.0 (2011-12-03-10:15) with flyswatter rev-b

I am trying to use openocd from a xubunutu desktop machine,

I installed openocd 0.5.0 using “sudo apt-get install openocd”

but I seem unable to talk to either my beagle board or my panda board with my flyswatter

I get the following errors and am at a loss as to what to do next …

openocd -s lib/openocd/ -f interface/flyswatter.cfg -f board/ti_beagleboard.cfg

I’ve solved my issue, (RTFM!) by looking at http://www.tincantools.com/wiki/Flyswatter_How_To

I’d put the jtag daughter board at the beagle board end not the flyswatter end of the jtag cable thus reversing it. (been carefull to make sure the red line was on pin 1). all works are exected once the user error was fixed.

Glad you got it working. For future reference, OpenOCD TCT information will live at elinux.org. Here’s all of the pages there so far: http://elinux.org/Category:TinCanTools
