Bricked Jaguar?

I have tried to "factory reset" the Black Jag without success.

I've switched over to using BDC-COMM with a USB to Serial Adapter for the time being.

I have also tried to "recover device" with BDC-COMM for the Black Jaguar, also without success.

Both these Jags simply appear to be bricked.

What is the EXACT message in the 2CAN webdash when you attempt to flash?

Mike,

I wish I had documented that when it occurred, unfortunately I didn't.
So I can't honestly be 100% sure what it was.

My best memory was a "Timeout Waiting for BootLoader"
But that could have been on the 2nd attempt.

Are you wired or wireless when attempting to update? One jag on the Bus or many Jags on the Bus? Have you tried isolating the problem jag and then flashing it?

Mike,

It was done wired, and it was done with 4 JAG's on the bus. It's very possible, the wiring of the CAN bus was faulty.

I bricked a Black one, then tried a Tan one.
Then I gave up and switched to BDC-COMM figuring it's either 2CAN or pilot error on my part(ME!). My USB-Serial has a CAN cable I made myself.

I was speaking with one of the students tonight (by phone) and he was running into CAN timeout issues on setup of working JAGs we had.
I had him recheck all the cables and the terminator, he did find one that was incorrectly made.

When I get some more time, I have one more spare TAN Jag, and I will retest the entire process and document it.
