Converting nRF52840-DK to BLE sniffer

Apica

Hi,

I'm following the guide to convert nRF52840-DK to a sniffer but I couldn't manage to flash the .hex with the "Programmer 3.0.4" software: it listed the device but it didn't allow me to load the new .hex (Erase & write button is disabled). Do I need to do any extra step to flash the firmware to the board?

Thank you

    Hi there,

    Some questions:

    1. Which revision of the nRF52840 DK are you using? It should be printed on a sticker on your development kit.
    2. Are you able to flash the development kit with any other fw such as the examples in our SDK?
    3. Have you done any modifications on the development kit such as soldering or cutting the onboard solder bridges?

    regards

    Jared

    1. It's PCA10056 2.0.1 2020.25
    2. I've been able to flash other firmware using If BOOT/RESET button (J-Link OB-SAM3U128-V2-NordicSemi 170724.bin) but I usually use the board to flash external boards.
    3. No, I just plugged external wires to flash SWD devices, but now they are removed.

    Hi,

    Are you able to flash examples using nRF Command Line Tools?

    For example, if you're using nRF5 SDK you could flash the blinky example with:

    nrfjprog --program blinky_pca10056.hex --chiperase --verify

    You find the hex in the nRF5SDK at:

    SDK_ROOT\examples\peripheral\blinky\hex

    regards

    It failed with the following code:

    [error] [SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error.".

ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

    Adding the --log file I ended with the following file:

    I usually flash using Zehyr build, and I checked that is still working.

    Hi,

    Seems like you have an issue with nRF Command line Tools. 

    What are you using to flash it after building the project? Are you using VS Code to flash it? Or do you always set the board in bootloader mode and then drag the hex file over to the folder after building the project?

    regards

    Jared
