You could try installing the Troubleshooting methods mentioned earlier in this Thread. Also, you can try nrfjprog --recover followed by nrfjprog --eraseall in your command prompt.

See if this helps.

Hi PK,

[quote userid="107729" url="~/f/nordic-q-a/81122/5340dk-can-t-be-recognized-as-jlink/336588#336588"]1. Could you confirm whether the solder bridge SB40 has been cut at any point on the DK?[/quote]

I have checked the SB40, it havn't been cut.

I am downloading the nRF Command Line Tools 10.15.0, about 10 minutes later it will be OK.

On the Jlink IC, there is 'PCA10095 0.11.0 2021.10 960127268', maybe this is the Jlink version.

But I can't find the version of DK, where can I find it?

Hi Helen,

You cannot do the step 4 as easily as mentioned in the Thread, which is what I mentioned earlier. This is because these downloadable options are currently available only for nRF52 DK. I can guide you through the steps for the nRF53, now that we have ruled out all the options from steps 1,2,3,5 and 6.

1. Could you confirm whether the solder bridge SB40 has been cut at any point on the DK?

2. Also, could you kindly download the latest nrfjprog version (10.15.0)

3. Please tell me which version of DK is it that you are using and also the J-Link version.

Hi PK,
I have try the steps 1,2,3,5,6, and there isn't any exception.

So I tried step 4, power cycling the DK with pressing the RESET button, there is not a Stroage Device named 'bootloader' appear.

What can I do now?

Hi Helen,

Then you probably have accidentally deleted the firmware like you had suspected. You could follow this Thread and try troubleshooting.

First, we need to confirm whether this is the issue, so please try the steps 1,2,3,5 and 6 from the thread and then we can move to step 4.

Then, reinstalling the firmware in the nRF53 DK's is not quite as easy as in the nRF52 DK as mentioned in the thread.

Hope this helps and kindly let me know how it goes. We can go onto the step 4 after you cross out all others.

Kind Regards,

Hi PK,

Yes, I have tried 3 USB cables, which are fine with other DKs.

Hi Helen,

Did you try using a different USB cable? Just to make sure that the cable has not become faulty.

[quote userid="107729" url="~/f/nordic-q-a/81122/5340dk-can-t-be-recognized-as-jlink/336197#336197"] Is your device being recognized by your PC when you connect to the PC using USB cable?[/quote]

No, when the DK connect to PC, there isn't any device on the Device Manager.

I know under normal conditions, it should be regonized as Jlink and serial port.

Hi Helen,

I am looking into it now. Is your device being recognized by your PC when you connect to the PC using USB cable? If yes, then did you try opening via VSCode or SEGGER? Is the device being detected there?

RE: 5340DK can't be recognized as Jlink

helen — Wed, 27 Oct 2021 11:24:26 GMT

I use programmer(nRF Connect for desktop) and J-flash.

And the DK is not detected.

Are you using VSCode or SEGGER? is it not being detected there?
