I see you weren't registered when you initially posted this question, so I accepted Hung's answer for you. Great that you got it working!

I saw that you have the jumpers on port P8 (near R5, R5) connected incorrectly. They should be connected vertically not horizontally (as in the picture)

Please refer to section 2.1 in the nRF51822 Evaluation Kit Userguide v1.0 (version 1.1 is for v2.0 Kit)

Or you can have a look at the picture here:

No problem.

I was able to program the chip before and I am currently using a BLE board now for testing as the ANT board is out. The problem might be related to using the debug pins (R5/R6).

Using nrfjprog --recover I get the following errors: System off disabled until pin reset or power on reset is done. ERROR: An error occurred while connecting to the device

Using nrfjprog -p (or --pinreset) does give the error: ERROR: An error occurred while connecting to the device

I am sorry for a late response.

Could you take a photo of your board ? Have you make sure the board is properly powered ? Were you able to program the chip before ? If you were, do you have any idea on what may cause the chip un-responded ?

Could you try to use nrfjprog.exe tool to recover ? You can open Windows command prompt and type:

nrfjprog --recover

If error occurs, please send me a screenshot.

The board is still out of order, any thoughts would be appreciated. Thanks.
