Hi,
I've a Terayon TJ721X with a 8 pin JTAG adaptor.
Unfortunately, it doesn't match the standard 8 pin JTAG layout and I can't follow the track because the PCB is a multilayer one.
=> I'm stuck with no idea how to know which PIN of the JTAG connector does what.
I saw on the Internet that it exists a program which can detect the JTAG pin layout.
Its name is "jtagenum" which run on a Arduino platform.
Other implementation exist (http://www.openrce.org/repositories/users/cyphunk/JTAGenum.pde) and **can be** (according to the authors) adapted easily to the AT90USB controller, which is equipping the blackcat usb board.
I think it will be a very nice improvement to the blackcat usb program.
Regards,
Vincent
