My nrf52840dk stopped working after programming

[Avi]

I am trying to operate a BLE5 sniffer with nrf52840dk

After connecting the dk to nrf connect desktop and programming it with a wrong code (by mistake), it is not able to read the memory content again.

I put the file J-Link OB-SAM3U128-V2-NordicSemi 170724.bin in the BOOTLOADER folder after I pressed the reset button.

Then connected again - but in nrf connect I cannot get any feedback after this line:

"Using nrfjprog to communicate with target"

When I try to use nrfjprog on CMD line, I get this error:

nrfjprog --eraseall
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

my dk is pca10056 2018.49

my jlink is JLink_V640

My usb cable is connected to J2

I am using USB power source (VDD option is not working)

The second switch is at default sate

and the VEXT-NRF is "On"

How to resolve this problem?

[Avi]

If this will help to analyze what happened and how to fix The last thing that I did while the 52840dk worked was to follow the guidelines in https://github.com/NordicSemiconductor/nRF-Sniffer-for-802.15.4/blob/master/README.md

I probably did something wrong (maybe programmed something into J3).

How can I fix it and bring back my 52840dk functionality? I cannot see the memory content any more and not able to program it.

Could you take a picture of the whole DK, and share it with me? So I can check all the switches etc.

Cheers,

It looks like "SB41" is cut from the picture, but it's hard to see. If that is the case, you'll need to short the pin header next to it.

Everything else looks to be OK.

 

Kind regards,

Håkon

SB41 is not cut. I will attach a picture also. I also tried to short the header - but still - I cannot access the memory

Hi,

 

Could you try to upgrade nrfjprog to the latest version (it's a part of the nRF5x command line tools), then use the recover function?

nrfjprog --recover -f nrf52

 

Kind regards,

Håkon

I am already using nrfjprog version 9.7.1

Should I upgrade? 

[Avi]

As I wrote above - this is the log I got:

I ran the command nrfjprog --eraseall --log and got the following result.

Please upgrade to the latest, and use "nrfjprog --recover -f nrf52".

Kind regards,
