Hello,

 

In our custom design(with out CPLD), there are two t1024 processor supplied by identical different power supplies.... I am able to connect jtag with corewarrior for one processor but not with other processor and getting error related to IR length.... What can be possible reason of this issue??.. I can see toggling of clk, tms and tdi.... But occasional toggling on tdo line....

What can be possible reason of this issue??.

 

Regards

Gaurav
