ADuC7023 Eval Board not flashing

Hi,

I have been using ADuC7023 Eval board 40-lead rev.B for about a week now. Got no problem debugging and downloading to it using mIDAS-Link until today. I just debugged using the latest FW with just a slight modification like toggling P0.7 but in that last flash J-link cannot connect to it until now. Kindly advice on how to fix this. Thanks.
