CCS/AWR1642: XDS560V2 can not connect to C674x in AWR1642

Adam,

Have they selected the right DSP code C6748 ?

Hi Raghu,
   Yes, the core is set correctly.The JTAG test connection in ccxml can pass, but when they connect the C674x. Above errors happen in GEL_EvalOnTarget("C674X_0", "GEL_SetWaitInResetMode(1)");.  What is the meaning of the errors above?

DSS_PreConnect_CheckResetStatus()
{
    uint32_t pwrap_dprec0_rd = 0;
    uint32_t gempwrsmcfg4_rd = 0;
    int ctxWasConnected = GEL_IsConnected(); /* Store CCS connection state */

    if(0 == ctxWasConnected)
    {
        GEL_Connect();
    }

    pwrap_dprec0_rd = PWRAP_DPREC0;  /* Debug Sub-Domain Power Reset Execution Control Register for DSS */
    gempwrsmcfg4_rd = HW_RD_REG32(DSS_REG_GEMPWRSMCFG4_REG);
 
 
    // Check if PWRSMLRSTHALT is set
    if(0x00020000 == (gempwrsmcfg4_rd & 0x00020000))
    {
        // Check if DSS is powered-off or in application-controlled reset
        if((0x00000000 == (pwrap_dprec0_rd & 0x00000020)) || (0x00020000 == (pwrap_dprec0_rd & 0x0007C000)))
        {
            printf("--->> DSS is under application controlled reset.  Prior to connecting this reset must be released.\n");
            printf("--->> The debugger will enable \"Halt On Reset\" and release the application-extended reset\n");

            GEL_EvalOnTarget("C674X_0", "GEL_SetWaitInResetMode(1)");
            printf("--->> \"Halt On Reset\" has been enabled on the C674X_0");
            DSS_ReleaseDSPHalt();
        }
    }

    if(0 == ctxWasConnected)
    {
        GEL_Disconnect();
    }
}

Hello Adam,
Can you confirm that they have flashed xwr16xx_ccsdebug.bin or demo application to AWR1642 device and switched the device to SOP-4 mode before connecting to DSS JTAG?

Hello Jitendra,
Thanks for the good suggestion. I am still checking it with customers.

Best regards,
