DS-5 CMSIS DAP Connection Issue

carlo val gocela

I experience errors in debugging using the DS-5.

The debugger have a 50/50 chance of connecting.

This issue is related to TCP.

Scenario:

1. Compile and debug.

     Result: Successful

2. Stop and disconnect

3. reconnect and debug

    Result: - sometimes Error

               - sometimes Connected

    Hi,

    I tried to replicate this yesterday using a Phytec Freescale Vybrid based dev board and didn't have any trouble connecting over CMSIS-DAP to the Cortex-M4. This was using DS-5 v5.20.

    Are you running DS-5 in a virtual machine inside of Windows? That can be a potential source of USB issues.

    I suggest that you get in touch with ARM technical support if there isn't an obvious fix.

    Thanks,

    Joe
