Could not find supported CPU core on JTAG chain

We have made a customized board for micro controller ADuC7026 by following almost same schematic given for the evaluation board. When I was trying to program using miDAS-Link its giving error "Could not find supported CPU core on JTAG chain". I tried changing the JTAG clock to adaptive and 1000 KHz also, but still same problem exists. Once it got worked properly ( so I guess PCB and schematics are correct), next day same problem repeated.


I have tested same configuration for evaluation board also, Its working fine.


We replaced 2-3 IC's also. Please can you suggest whats going on wrong and any other method to test the controller.


Thanks and Regards
