    Hi,

    Which board do you use? 

    Where did you get modem file from?

    Could you provide more information about your screenshots?

    Best regards,
    Dejan

    Hi，

    I used the nRF9161-DK development board and a board of my own design. When using the development board, I can burn programs written into the modem, but I can't burn successfully using the board we designed. Our board is using jlink as the emulator, perhaps because the emulator is different when burning?


    modem file: mfw_nrf91x1_2.0.0 is downloaded from the official website.

    The first screenshot shows that VsCode cannot detect the chip when connecting the board we designed using jlink, but can burn and debug it
    The second screenshot shows the programmer's state when burning modem firmware using jlink, unable to select the write option

    Hi,

    Regarding the issue with Programmer application, have you pressed first "Erase all" button before you tried to press on "Write"?

    Best regards,
    Dejan

    Hi, Dejan is currently on vacation, so I have taken over this ticket.

    I have asked our developers to look at this, and will get back to you when I have more information.

    Best regards,

    Didrik
