nRF52840 EVM board is not working!!!

[Urvisha Andani]

Hello all,

I am working on nRF52840 EVM board.

I am not changing any thing in  nRF52840 EVM board.

I was using nRF52840 board for downloading firmware in external custom board and initially it's working fine.

But now it's not working. We connect USB cable but in EVM board, D5 LED is not blinking.

My question is what kind of problem is there in this EVM board? 

Give solution for solving this problem.

Thanks & regards

So that's the nRF52840-DK:

You mean the nRF52840-DK itself is no longer working, or your custom board is not working ?
