K82 freedom board doesn't power up.

K82 freedom board doesn't power up. While I was installing the JLink open SDA bootloader to the board. It got disconnected from the laptop. And now it doesn't power up. The green power doesn't glow. I tried checking the power supply with a multimeter. It looks ok. Please help.

I do a test with FRDM-K82F board and it need to upload J-Link OpenSDA V2.1 firmware.

Customer can let board enter into Bootloader mode again, then plug the firmware file.

Wish it helps.

Actually the board is not powering on only. So it is not possible to get it into bootloader mode.
When I power it using the USB, the green power led doesn't light up..

Please check the USB port you are using.

The OpenSDA is powered by P5V_SDA with J5 USB port;

When you power the board with J11 USB port, which doesn't provide power to OpenSDA, only power K82 chip.

Wish it helps.
