Hi
I have been using this DK board since 8 months and it was working fine, but suddenly when i plugged in today its not working
1. No LED's are ON (Not even LED5).
2. No COM port is showing up.
3. it used to show up a folder with embed firmware when it connected but now its not.
NOTE: I can see voltages at VDD pin and 5v pin.
i have tried with latest J-Link version (5.20a) also. but no use, and since i cant even see COM port i was failed to try with J-Link Commander.
i have tried all the steps in this below link

Best Regards,
Raj.
