RVI ICE box can't connect to target.

As we know, JTAG connect target by TDI/TMS/TCK/TDO/nTRST pin in general.
Now I try ICE box to connect target failed, but TDI/TMS/TCK/TDO/nTRST pin is fine because I can connect target successfully by JLink.
So I want to know whether other pins of JTAG cable port cause connection failed? In my board, the pins 11/17/19/2 are floating. They are RTCK/DBGRQ/DBGACK/Vsupply.

And how will I modify the board to let ice box work well?

Any comment will be great appreciated.

    Hi Joseph,

    The version of RealView Debugger is 3.1, and have updated the firmware. I can connect successfully to ARM cortex-M3 stardard board SMT32, so I think the box and firmware should be OK.

    Regarding the fault,
    1. sometimes, when I double kick the selection of usb ice box, it said "no connection to target".
    2. if 1 is ok, but set a jtag speed is 100K and run Auto Configure Scan Chain, it will fail.

    But the connection is fine. I try it ok by J-Link.
    I ever thought the ICE box was bad, but it still can connect SMT32 successfully.

    Thank you very much.
