Firmware version 2.18 is the latest for FRC but 2.5 should work fine.

A red LED means you do not have CAN connectivity, bad cabling, bad termination resistor. If the 2CAN LED is intermittent between green and red then you have an intermittent can connectivity issue, you may confirm this in the web dash by viewing the CAN tx/rx error counter. If the error counter is incrementing you have a CAN connectivity problem.

I have never had a problem updating JAG firmware with multiple JAG's on the BUS as long as they each have a unique ID, however when you are trying to troubleshoot, it is always a good idea to make the problem as simple as possible.

Team 857 is having a very similar issue. Our grey jags had v92, and we tried today to update to v101. Attempting to flash resulted in timeout errors, and after a few attempts, the light on the jags turned off. We have not yet tried the new black jags.

I tried flashing v92 back on, but the same timeouts occurred. We did then update the 2CAN from v2.1 to v2.18. Still no success. The CAN always flashed green after booting.

We were able to go back to V92 easily. I'm not sure if it helps, but we power cycled frequently during the whole process.

How many Jags are on the BUS when attempting to flash?
What is the TX/RX error count in the 2CAN web dash and is it incrementing?
