Flasing Tan jaguars?

How do I flash the tan jaguars to the latest firmware? I have them plugged into my computer directly via a serial port, with cables and a terminator that have worked on black jaguars. When I press enumerate, the BDC-COMM software does not recognize the tan jaguar. Thanks.

The Tan jaguar does not have a serial to CAN bridge like the black jaguars. You need to connect a black jaguar to the computer, and then the tan jaguar to the black jaguar. See question 10 in the Jaguar FAQ at http://www.ti.com/jaguar
