The extension automatically populates and updates the list when you connect a device or click the Refresh Connected Devices button. It does so by calling the version of the nRF Util tool (nrfutil device list command) bundled with the extension, which may or may not match the latest released version of the nrfutil device command (see nRF Util device command changelog).
SEGGER J-Link compatibility is required for devices to show up in the Connected Devices View.
- If you are working on Windows and your device does not show up in the View, but it does have the J-Link OB on-board debug probe, check if you have SEGGER USB Driver for J-Link installed (required for support of older Nordic Semiconductor devices in nRF Util, as per extension prerequisites).
- Some devices, such as the BBC micro:bit, do not have J-Link by default. You can convert the onboard debug interface to a J-Link OB using the J-Link upgrade instructions.
