nrfjprog failed to erase nRF52832 device

snowuyl

I would like to use nrfjprog to erase nRF52832 device. But it failed with "An unknown error". The nRF52832 device connect to laptop through J-Link USB interface.

D:\Nordic>nrfjprog --log --family nRF52 --eraseall
[error]: [SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error.".

    I encounter another problem. I can't program softdevice if I program bootloader before program softdevice. But I can program softdevice if I don't program bootloader before program softdevice. Does it mean bootloader has problem?

    After changing board.h, I can use nrfjprog to program bootloader, softdevice, and application hex file. But I still can't see log messages of bootloader.

    Please use the secure_bootloader example with _debug version to get debug log.
