Im not sure if the LM3S2965 eval board (your board) comes with firmware that reflashes Jags or if that firmware has been ported from that dev board.
Be sure to read the RDK-BDC User's Manual before you do anything...

It explains how to reflash firmware.
Also there are a couple of possible gotchas.
1) The JTAG/SWD Connector on the Jag is a mini 2X5 pin connector that requires a small pcb converter that goes from that to a traditional JTAG connector (this is also explained in the user manual).
2) I've noticed that some Jags ship WITHOUT the 2 X 5 pin connector and the vias where the pins go are wave soldered over so you may have to purchase the pin connectors yourself and solder them on. Peel the sticker at the bottom of the Jag and you will find a hole where the pins should be (I just remembered that I had to do this on a particular jag). I found the part no for the pins in the rdk-bdc CD for the Jaguar, which is also on LM's website. If you can't find it and can dig it up.
