CCS v5: Error message after debugging. (C28xx: Can't Run Target CPU: (Error -1140 @ 0x3F76C1))

Hello,

I'm running Code Composer Studio Cs5 under Linux Mint 14, Cinnamon and everything works fine, but from time to time there comes a load failure with the following error message.

C28xx: Can't Run Target CPU: (Error -1140 @ 0x3F76C1) Lost debug connection to device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.73.0)

When I reconnect the the Target or when I restart Code Composer and I debug it again, it works for maybe one or two debugs until the failure comes again.

Does anybody know, how I can avoid this error, without to reconnect the controller after every debug?

Can anybody tell me what this JTAG settings mean?

Best regards,

Don
