we bought NRF52840 to test other boards, firstly a problem happened, when change a new NRF52840 the testing could pass, so we doubt the firmware inside it was lost, how could we solve this problem?
Hey,
It could have been because you have accidentally erased the firmware for the JLink chip on your DK. It happens when u power cycle with the reset pin pressed. All you need to do is press the reset button and try turning on the DK again, the light on the DK will blink and the DK will be shown as a bootable device on ur PC, if that works out you just have to download the binary of the firmware (link) used by the interface chip and drag and drop it onto the bootable device, after that power cycle the DK (without pressing the reset button) and everything should be back to normal. Please do refer to this answer (link) by @Bjørn Kvaale for reference.
Cheers.

Hi Pan,
Are you using nRF52840 DK?
What is command-line tool version? You can get it by typing nrfjprog -v.
Please run nrfjprog --recover. If it still fails, please provide the log.

Hi Amanda,
Thank you so much for your kind reply.
Yes, we are using nRF52840 DK, nrfjprog version: 10.8.0. After running nrfjprog --recover. it still fails, pls check the error as below for 1 nRF52840DK:
Hi Pan,
Pan Yinliang said:C:\Users\Administrator>nrfjprog --recover
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
The lats operation of nrfjprog --recover seems to work.
Can you check the issue is fixed or not? If not, you might need to update the command-line tool to the last version, and do nrfjprog --recover again. If it still fails, please provide log by typing nrfjprog --recover --log.
