Using nrfjprog, unable to perform "--recover"

[Loren Rogers]

On a custom board with the NRF9160 chip, performing `nrfjprog -f NRF91 --recover --log`, AND `nrfjprog.exe -f NRF91 --coprocessor CP_APPLICATION --recover --log`, I get:

[2022-Sept-07 11:32:46] [debug] [SeggerBackend] - Select AP 255, DP Bank 0, AP Bank 255

[2022-Sept-07 11:32:46] [debug] [SeggerBackend] - Attempting to clear any configuration errors in debug port before closing connection.

My ultimate goal is to program mfw-1.3.1 on this flash.

Hi,

There is a problem with uploaded log. It cannot be opened. Could you please send the log file again? This can be done using Insert Image/Video/File option and press Upload to resend the log file.

Which J-Link version (JLinkARM.dll) do you have?

Best regards,
Dejan
