Can not connect to nRF5240 through DK (PCA10040) after updating nRF Connect

[efurunes]

I have for a long time been using the PCA10040 DK to program my custom board with nRF52840.

This has been working flawlessly.

HOWEVER, after I updated nRF Connect to version 3.3.3 and the Programmer app to the latest version v1.4.2, I can no longer program the nRF52840 on my custom board.

(nRF Connect can access and program the nRF52832 on the PCA10040 If I disconnect my custom board)

I dont know the version numbers of the previous combination that worked.

I tried to downgrade to nRF Connect version 3.3.0 (and 3.2.0), but the problem persists.

I dont know how to change the Programmer app version, so this remains at v1.4.2.

Segger version is 6.70d

Is it possible that something have happened to your board to make the hardware fail somehow? Check electrical connection, power supply etc.

Can you try to run the nRF Command line tool directly, e.g.:

Hi,

It is a bit hard to read the image since it is so small, but I tried using the nrfjprog:

C:\TEMP\RCC1601\EMC>nrfjprog -f UNKNOWN --log --program BLE.hex
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.

C:\TEMP\RCC1601\EMC>

It might be that something has happened to the board (even though it seems to work fine). I will investigate...

I have updated the screenshot, hopefully more visible now. Here are the commands you can run in any case:

nrfjprog --version
nrfjprog --recover

Best regards,

Hi,

it did not work:

C:\TEMP\RCC1601\EMC>nrfjprog --recover
Recovering device. This operation might take 30s.
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.

C:\TEMP\RCC1601\EMC>nrfjprog --version
nrfjprog version: 10.8.0
JLinkARM.dll version: 6.70d
