Emulator in eZdsp F28335 crashes

Other Parts Discussed in Thread: CCSTUDIO

Dear colleafues,

I am using for some time an eZdsp F28335 and everything was fine till yesterday. When trying to dowload to target and execute a code that had been running succesfully many times before I succeeded to download it but wneh hitting Run in CCStudio v3.3 there appears the following message:

Error: Error 0xA00020A0/-1250 Error during: Execution, Target Communication, Control, Device driver: Lost USB connection to emulator. You should ABORT and restart to re-establish the USB link.

I tried several times restarting the CCStudio and the board (power off/on) but all the time the same problem appears. Sometimes I am able to single-step trough the code for some instructions but then the problem appears again. The LED DS201 becomes constantly on wneh the error appears.

Could you please tell me how this has to be fixed? I see some postings on the net related to the same problem but no clear fix is given.

Best regards,

Radek
