Supplying opposite voltage via power jack.

Hello Guys, I have this small doubt which actually did something to my MEGA which i am not able to rectify.

I by mistake supplied opposite voltages to my mega from the power jack. Now my program doesn't get uploaded on it. All the Led's are working normally, and my board is also not getting heated up.

Any solutions please? Really tensed!

The error i am getting is -

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

Thanks in advance!

Do you have another Arduino and does it work properly?

...R

Yes Yes, I have an Uno and one more Mega which are working completely fine. All the programs are being uploaded completely and as they are meant to be!

But this one is having the same problems again and again!

Sounds like bad news.

You might try using the Uno with the ArduinoISP program (in the Examples) to upload to the problem Mega using ICSP.

Nick Gammon has some useful programs that may help with diagnosis.
