nrfjprog runner not supported (jlink should be used)

[douglas.malnati]

Windows 11, NCS v2.3.0

I have an application that builds but doesn't flash.

Executing task: nRF Connect: Flash: BikeControlBoard/build (active)

Flashing build to 683684592
west flash -d c:\Users\dougl\git\nRF52\app\BikeControlBoard\build --skip-rebuild -r nrfjprog --dev-id 683684592 --erase

-- west flash: using runner nrfjprog
FATAL ERROR: board adafruit_feather_nrf52840 does not support runner nrfjprog
To fix, configure this runner in C:\ncs\v2.3.0\zephyr\boards\arm\adafruit_feather_nrf52840\board.cmake and rebuild.

Here is the file (C:\ncs\v2.3.0\zephyr\boards\arm\adafruit_feather_nrf52840\board.cmake)

board_runner_args(jlink "--device=nRF52840_xxAA" "--speed=4000")

board_runner_args(pyocd "--target=nrf52840" "--frequency=4000000")

board_runner_args(blackmagicprobe "--gdb-serial=/dev/ttyBmpGdb")

include(${ZEPHYR_BASE}/boards/common/jlink.board.cmake)

include(${ZEPHYR_BASE}/boards/common/pyocd.board.cmake)

include(${ZEPHYR_BASE}/boards/common/blackmagicprobe.board.cmake)

What change should be made?

Also I just want to use jlink as the runner.

If I run the flash command by hand, which I don't want to do under VSCode, it works:

west flash -d c:\Users\dougl\git\nRF52\app\BikeControlBoard\build --skip-rebuild -r jlink --dev-id 683684592 --erase

How do I get VSCode to use the jlink runner?

Thanks.

Hi,

Try adding this to the file:

include(${ZEPHYR_BASE}/boards/common/nrfjprog.board.cmake)

Hi that didn't work at all.  It simply made nrfjprog be the runner.

Can you tell me how to get jlink to be the runner?

According to the team, It can be done through the custom tasks

Hi, I read through the links but it's not clear at all what I'm supposed to do.

Can you help by pasting whatever I need to do to make jlink be the runner?

As in, the VSCode extension allows you to hit ctl+shift+e, which will build, then flash.  I want it to use jlink when I hit that key combo.  How do I do that?

Thanks.

Here is the example code in the docs:

Then in a my-flash-script.sh you can do whatever you want.
