I have resolved the problem, thanks for your reply and help:

My solution came from another article: https://devzone.nordicsemi.com/f/nordic-q-a/41538/nrf52840-dk-j-link-not-working/161585

It looks like I am missing some driver about J-Link, just cast the bin file from the article into BOOTLOAD and reboot the development board, hope this helps someone in need.

Thanks again for your help and I wish you a happy life!

--> From the above error I think, J-Link in your NRF-EVK is not being detected by your PC.

I suggest raising a new ticket with the above error as I do not have any knowledge on this.

Sorry for that.

I surely reply here if I get any reference to the above-mentioned issue.

Thank you for the file and reply. I plugged in RF52840DK but it didn't respond and LED5 didn't flash. It flashed only when I detected it as BOOTLOADE according to your method. When I tried to flash J-Link bin file to my development board, it showed ERROR: Cannot connect to J-Link. (I didn't know what NRF-EVT was, so I just connected the development board directly to burn it by default.)what should I do？

[quote userid="135037" url="~/f/nordic-q-a/106397/device-stopped-working-error-device-not-detected/494451"]Hi, I have the same question as you, I would like to ask what is the exact step ticket for this and what is the J-Link bin? I can't execute the g command directly now because it says ERROR: No debuggers were discovered. How can I mourn?[/quote]

J-Link bin is FW bin file which runs in J-Link controller.

I have attached the J-Link bin, I do not remember from where I downloaded the bin file.

devzone.nordicsemi.com/.../j_2D00_link_2D00_fw.bin

You can try to flash the above file to you NRF-EVK.

Thanks that worked.

It did not work at first, I repeatedly tried to upload J-Link bin to BOOTLOADER and reset using nrfjprog.

At second time it worked. It is now showing nRF52840DK.

Thank you once again.

You can try to download nrf Command line tools and see if you are able to call 'nrfjprog --recover' from a command line:
https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download

Are you sure there have been no modifications to the nRF52840-DK (e.g that you possible have cut any solder bridges or similar).

Don't use the PDK no, it's not supported. Even if you were to make it seemingly work, it should not be used.

[quote userid="2111" url="~/f/nordic-q-a/106397/device-stopped-working-error-device-not-detected/459211"]If you have old PDK's of the nRF52840 (prior to v1.0.0) these are no longer supported.[/quote]

--> I have one with v0.9.1(preview DK) and the other v1.1.0 (nRF52840DK, not preview). So, does this means the one with v0.9.1 does not work anymore?

[quote userid="2111" url="~/f/nordic-q-a/106397/device-stopped-working-error-device-not-detected/459211"]The problem you refer to typically indicate problem with the USB connections (e.g. using a USB cable meant for charging).[/quote]

--> I tried changing USB cable (3-4) and the same result.

The major improvement is with v1.1.0 is below:

I was able to connect with the PC and reset, I get BOOTLOADER connected and after I upload the J-Link bin I get J-Link connected.
The issue is I see J-Link in NRF-Connect App and not the board info(nRF52840DK).

Can you please help me with this as we are working on some project and they are using the 52840 variants, so these boards are really need for us. It would be great if 1 works for us.

Thank you, appreciate your support.
