Im not sure why your getting this error but if it makes the jags not work on other systems this might help you to get them running again.I helped fix a similar problem for another team through firmware this year. Their robot encountered the problem when running two cims and using pwn were their jaguars acquired flashing red lights and would not function. I was able to fix their problem using the bdc-com updating tool that the jaguars use for firm ware. to do this:
1.install bdc com on your computer (you can find it on texas instruments sight somewhere)
2.install black jaguir firm ware (i assume your using black jags, if your not you have to make a can connection between the jags)
3.use a db9 to rj11(phone line) cable and connect your computer into the correct can port on the jag,
4.you need a terminator plug so either borrow one at regional s or solder a resistor between the green and red wires on on some phone line then put that into an rj11 crimp
4.5.plug this into your jaguir
5.go to bdc com and see if in the upper right hand corner you get an error called gate fault.
6.if you do have a gate fault reset the jaguar to factory default
7.install black jag 101.bin on your jag
8.it should be unbricked. and the red light should go away
9.if you get the error "cannot access the boot loader" you have to use the reset button to manually factory reset the jag. then use black jag 101.bin on the jag.
Im not 100% certain how the gate fault error happens, i was not there to see this team break their stuff. But by messing with the jaguars firmware through a can to computer serial port hookup i was able to make it work for them again.
or you could just switch to victors, easier solution
-note if you don't have the gate fault error im not sure if the firmware reset will help you.
