Dear Bharath
The led coming on indicates that the code loaded into the board is running and depending on the airframe file that was loaded, may light an led on GPS lock. On the one hand it does indicate that the board is not completely dead. However, it does not indicate as to why you are not able to program the board.

Not able to program may be due to several reasons as below.

a) you need to first connect the USB and then power the board, only then will it enter program mode

b) the cables either at the molex end or the laptop end may be faulty and not making the connections as a result the autopilot board may not be entering program mode

c) Does the laptop recognize the device?/or if you put a removable drive does it show up. Was this the same laptop with the same software both OS and papaprazzi running while the board was working 

d) Have you set your environment variables correctly and also added yourself into the plugdev group as this is required for flashing the board?

e)was there any mishap/crash etc both physical and electrical that could have damaged the hardware on board?

f) what voltage are you providing as input to the board? should be atleast  >7.2volts

These could be some of the reasons I could of think let us know if you find any

Best Regards
