I'm currently trying to debug a p2041 with a CodeWarrior TAP but unfortunatly I am having some problems.

While using CodeWarrior Development Studio I get the error message:




JTAG Diagnostics


Starting Power at Probe test...

Test result: PASSED


Starting IR Scan test...

Error measuring IR length


i tested the TMS,TCK,finding that they toggle when a debugger operation is actively running.but i found that the TDO couldn't toggles at the SoC.What‘s the possible reasons ?thanks in advance.
