RVI ICE box can't connect to target.

Note: This was originally posted on 25th August 2010 at http://forums.arm.com

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.

It might be that the signal level of the TDO is too low for RealView-ICE.

Do you have access to a LVDS Probe v2?
