If you are running it on a single board computer (Raspberry Pi, Chip, BeagleBone, etc.), chances are that you have GPIOs readily
available. I know that both UrJTAG and OpenOCD provide support for GPIO-based JTAG interfaces, but it might be specific to
Raspberry Pi. If it is the case, then a little bit of UrJTAG code tweaking should bring you support on your favorite SBC.
Oh, that skips USB completely. I'll research that, thanks. This could turn
into a tester module in a box to send
to a contract manufacturer for testing of assemblies for correctness before shipping them to you. It would not have a keyboard,
just a go button that runs whatever it is loaded with. So the other thing to research is JTAG daisy chaining and how each device
under test is identified -- I guess it is just by the number of shifts it takes to get back to the master JTAG connector on the
box running UrJTAG.
