If you haven't already, please update the nRF Programmer App. If that doesn't work, try programming from another source, such as VSC, or using nrfjprog from the terminal to see whether the issue persists.

To install the nRF connection and programming, you could try using a different computer.

I see.

Are you running the newest version of the Programmer? Please try updating the nRF Programmer App if you haven't, and see if you get the same error when programming from something else, like VSC, or using nrfjprog from the terminal.

I assume you don't happen to have any extremely long wires?

Have you modified anything on the v3 DK? Like shorted any of the pads etc.?

Are you able to use the v3 board to program the SOC on the v2 board?

Does the other way around work btw? The v2 one programming the v3?

Hi Elfving,

What voltage is your external board running on? 3.3v?

Ans: Yes.

What was the nRF running on the custom board?

Ans:nRF52840

Are you able to use the v3 board to program the SOC on the v2 board?

Ans: Yes, When I use the V3 board to program the SOC on the V2 board. The log window still show me below error message:

Failed to recover NRFDL_DEVICE_CORE_APPLICATION core: async task failure for id: 101576830021 msg: [jlink] JLINKARM_DLL_ERROR (Origin: "Error when running operation: recover")

Device programming failed with error: async task failure for id: 101577851593 msg: [jlink] JLINKARM_DLL_ERROR (Origin: "Error when running fw program.")

Maybe I need to try use other PC to install nRF connect and program again.

Thank you.

I see. The thing is that the external programmer/debugger needs to operate on the same voltage as the SoC it is programming, so that could've been an issue here. But I didn't think there was a difference between the two versions in regards to that, even though the onboard debugger/programmer has changed.

What voltage is your external board running on? 3.3v? Are you able to use the v3 board to program the SOC on the v2 board? And what was the nRF running on the custom board?

Hello Elfving,

Please see below photo. Different DK results will be different.

Is this how you've connected the PCB to the DK?

Hello Elfving,

Do you have the DK switches in the default position?-----Yes!

Are you able to flash the nRF52840 when the SWD connections are simply disconnected?-----Yes!

Hello Elfving,

Here is how I connecting:

Such a connection can be program in the old version DK board.

Thanks.

Hello,

How are you connecting the DK to the programmer? And what are you using as an external programmer?
