Dear support team,
The j-link firmware of my nRF52840-DK v3.0.1 is no longer available. Please provide the firmware of nRF5340 so that I can repair the DK.

Hi,
The j-link firmware of my nRF52840-DK v3.0.1 is no longer available.
How do you see this?

Hi
How do you see this?
The nRF5340 in nRF52840-DK has lost its firmware. As a result, the 52840 chip on the development board cannot be burned and debugged. Please provide the nrf5340 firmware of 52840-DK. I will try to see if this development board can be repaired.
Because I connected the swdio and swclk of nRF5340, and then erased the firmware through the nrfjprog --recover command.
Ah,
Sigurd Hellesvik said:We can not provide firmware to the debugger.
This is what I think I recall, but I will check again if we can provide the firmware.
Good thing I checked, I was wrong.
Segger provides the binary. Since you have JLink installed you likely have it on your PC already.
If not you should be able to download it from https://www.segger.com/downloads/jlink/.
Could you let me know if it works or not?
Disclaimer: I can not guarantee that that firmware works, as I have not tested it myself
Looking more at this, I find that the .bin is missing the bootloader.
And I checked, and am not allowed to share the bootloader for this.
In this case, it will be a bit hard to reprogram the nRF5340.
By the way, what was your use-case for recovering the interface IC?
Hi
Verify that JLink_OB_nRF5340_NordicSemi.bin in \SEGGER\JLink_V794e\Firmwares cannot be downloaded to nRF52840 on the 52840-dk board.
Is there any other method I can use to repair my 52840-dk?

No, you can not repair the nRF52840DK if you ran nrfjprog --recover on the interface chip.

I formulated this question poorly.
I mean, what was the use-case for erasing it in the first place?
