Not quite sure what you mean here. Joe and I do not write the TI firmware we are only trying to help support it.

What is the color of the 2CAN led with only one Jag on the BUS? Do you have the latest 2CAN plugin installed (v66) and what version of 2CAN firmware are you running? If you have the latest firmware and plugin a red LED will indicate poor CAN connectivity. If you have a good CAN connection to ANY jag on the BUS you will get a green LED so until you are able to successfully flash one of the JAG's with the latest firmware do not add any more to the BUS. If the firmware flash update fails on the first attempt using the 2CAN try a couple more times there is a small bug in the latest version of the 2CAN firmware (2.18) that occasionally fails to flash the firmware on the first attempt. This is being fixed for the next release and only affects flashing the jags and has nothing to do with CAN performance.

You may already be aware of this but make sure you are using the correct version of firmware. The gray Jag has different firmware than the Black. The Black JAG firmware has the word Black in it.

It should not matter which method you use to update the JAG firmware. Your problem could very easily be your CAN cables or termination resistors. The fact that you were sucessful at loading version 92 tells me that the problem is intermitant, this points to cabling/termination or you are trying the wrong version 100 firmware.
