Hello Aobo,

We have been receiving the issues related to programmer app and nRF53 in these days. Since developers are making changes to the back end of different NCS applications which causes unfortunately some bugs. We are working to fix it. Current solution is to download an older version of the programmer app. Here in this post you can find how to do this https://devzone.nordicsemi.com/f/nordic-q-a/83650/nrf-connect-programmer-2-2-0-broken-for-nrf53 .

Please try and let us know the outcome.

Best Regards,

When I add files without selecting the dev kit. The file memory layout is different.

Hi, Kazi,

I tried

nrfjprog --recover --coprocessor CP_NETWORK

nrfjprog --recover

I can erase & write. But the nRF Toolbox app cannot find the Dev Kit after I reset(or re-power) it.

Hello Aobo,

You can try to disconnect the DK and inset it again, pressing the reset button (SW5) and then read the flash.

The issue might be the readback protection is enabled. You can also recover the device from command terminal using following command.

nrfjprog --recover --coprocessor CP_NETWORK

nrfjprog --recover

This command is for removing readback protection and for performing erasing and flashing of the device as well. One thing you have to make sure that to recover the network core first.

Try this and let me know the outcome.
