I am not certain of the cause. It appears to be a power-up issue. The Jags became nonresponsive (solid red LED as seen in the video) when power was cycled(applied then removed repeatedly). Here is my theory as to why. The Jag I believe uses an ARM processor. My experience with ARM chips is that they require more time to stabilize than most processors upon intial powerup. They have seperate voltages for the core and peripherals. The lock up could be caused from a timing issue between powering the core and peripherals. Again this is pure speculation. I am basing this on similar experiences with the Chicklet which also uses an ARM processor. Whatever the cause may be I hope FIRST addresses this issue prior to Kickoff.

They Jag seems like a very promising speed controller. It has great low-speed control and fast response. It supports CAN and can decode quadrature. All of this functionality is great but if the device locks up and causes a team to lose just one match, then as far as I am concerned the device is as good as garbage.
