Problem with TMS320F28035 connection with XDS100v1 emulator

Other Parts Discussed in Thread: TMS320F28035

Hello,

I am suddenly having problems trying to connect to a board with a TMS320F28035 with an XDS100v1 emulator. Everything was working fine. Now it is not. I have another identical target. It connects, and allows programming just fine. I also have another identical emulator, and it responds the same. Works on one, but not the other. It's like it locked the processor or damaged it or something. I have had this happen in a similar way once before, but I assumed i shorted something out and let the magic smoke out, although I didn't think it was likely.

 I get the following errors in the console on CCS  Version: 4.1.3.00038. I have some issues with CCSv4 stability, and this could be related to a crash or something.

C28xx: GEL Output:  Device Calibration not complete, check if device is unlocked and recalibrate.

I am running Win7-64.

Can anyone help?

Thanks,
