Hi,

 

I have been using USB TAP successfully from last 2 years.

 

Because of some other project, I had not used the USB TAP for 3 weeks. 

 

Now while downloading Code to EVM or Application Board, I get various errors saying

 

1. Core not responding

 

2. Unable to Write to Flash

 

3. The Flash is locked

- In this case i went to Debug -> 56800E -> Unlock Flash, and tried again, in this case i get error mentioned in 2.

 

USB Drivers seems allright, as it shows under windows device drivers, also i installed update of USB TAP.

 

and i have captured comm data using "show com" in ccs window. 

 

Any help / direction to solve this problem would be helpful, 

thanks in advance.

 

San
