Hi,
I’ve been looking at goJTAG and it seems to be the ideal partner to OpenOCD. http://www.gojtag.com/
Its a front end for a boundary scan system that understands BSDL files.
It’s written in Java, so integration is a bit of an issue, but it seems that adding support for libusb and libftdi should not be that difficult, but perhaps that is not the best way…
One problem would be that OpenOCD and goJTAG could not exist at the same time as they both talk directly to the hardware. However if OpenOCD provided a TCP socket that sent raw JTAG commands then goJTAG could talk through it (goJTAG already has a raw JTAG client).
Cheers,
Jason.
