CCS collapse soon after DSP runs

Hi all,

We are doing a AC/DC converter project using DSP to control the IPM. we are confronting a weird phenomena. CCS disconnected to the target and did not respond soon after the program was download into the DSP and run, in other words, the DSP kept running correctly but CCS crash. However, if no ac input power is supplied to the AC/DC converter (i.e. no high voltage for the main circuit), the DSP runs correctly and CCS works well. Does anybody have the same problem?

Hardware: F28335 controlCARDs with Docking Station with USB connected to the PC.

Software: CCS 3.3

Kind regards,

Jerry
