I've been working on a project (http://openpilot.org) that is using a JTAG based on the FLOSS-JTAG. When I tried using two JTAGs at the same time, I found that openocd couldn't tell them apart because these JTAGs didn't have serial numbers. The USB descriptors on these devices are absolutely identical so none of the existing differentiation mechanisms will solve the problem.
This patch provides a way to use their unique usb bus address to distinguish them from one another. I've been using it successfully for a few days. This concept is probably generalizable for other inexpensive USB JTAGs without serial numbers but I've only got FT2232 based ones to work with so this patch only applies to FT2232 devices. Comments appreciated. Stacey. _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
