nRF5340-DK programming issue

Hi Charles,

Issuing the command "nrfjprog -f NRF53 --eraseall --coprocessor CP_NETWORK" produces the same output that can be seen in the log section of the Programmer application, as in your picture. After restarting, type "nrfjprog -f NRF53 --recover --coprocessor CP_NETWORK" and "nrfjprog -f NRF53 --recover --coprocessor CP_APPLICATION" to enable the cores again.

Regarding nrfjprog --rbp command, there are two options, out of which only one "ALL" can be used in your case. Try typing "nrfjprog --rbp ALL". If the cores are locked, this command will be unsuccessful. Otherwise, it will work fine. Restart the device. After that run "nrfjprog -f NRF53 --recover --coprocessor CP_APPLICATION" to enable cores again.

In short, use --eraseall on specific core and use --recover to disable readback protection.

Best regards,

Dejan

Hi,

Customer already try the commands, below is the screen capture. It cannot fix the problem. We also attached the log for your reference.

Hi Charles,

According to the log, the nrfjprog version you have is 10.7.0. Although it is not the newest version, it is not very old. However, you could consider updating to a newer one.

 It might also be that you have PDK instead of DK. Could you please share what is the version of your nRF5340dk? You can find this information from the sticker on the board, beneath PCA10095.

Could you please check if nrfjprog can see the COM port of the network core by issuing "nrfjprog --com" command?

In addition, have a look at the following links:

When trying out the recommended solution with a bat file (given in the last link), make sure to replace nrf52 with nrf53.
