PCE is failed to find the DAP using DSTREAM-ST in DS-5

Hi all,

   I am using dsteam-st uint with ds-5(version: 5.27) to debug a pandaboard. PCE is failed to find the DAP when autodetect target and creat my platform configuration.

   i also use csat tool check the status, I cannot find the ARMCS-DP,and dvo 0 failed.  I think there is something wrong with the DAP,  could you give me some suggest about  the faliure with the PCE autodetection and how to access the DAP.

    %>chain dev=auto

    JTAG   clk 50000000A

    ID:0 UNKNOW_6

    %>dvo 0

    Thanks for your attention!

Best Regards,
