CCS/TMS320F28377D: IPC handshake problem between CPU1 an CPU2 in 28377D

Part Number:TMS320F28377D

Tool/software: Code Composer Studio

Hi  

I have a questions about the IPC handshakes between CPU1 and CPU2. I used the demo  in \controlSUITE\device_support\F2837xD\v200\F2837xD_examples_Dual\ipc_gpio_toggle and have no any change. But when I debug with xds100V2. CPU01 is runing in the   while(!IPCRtoLFlagBusy(IPC_FLAG17)) ; No breakpoint behind this can be get ! And I'm sure I have download the  cpu02 project to the cpu02. Also my another college found this question. We are very confused. I doubt if the cpu02 isn't working when I  debug the CPU01 when I use XDS100V2.  Because the Demo  has no change.

Thank you!
