Re: nrf52 debug with Linux VirtualBox

Hi David,


You can try adding the device to “USB Device filters” in the VirtualBox guest’s settingsàports à USB.


Usually, if the Segger firmware has updates, the JLink will try firmware upgrade hence will recycling the host MPU (Atmel) and by having the device in “USB Device filters” it will get re-enumerated, DFU completes and thereafter continue flashing firmware to target MCU (Nordic SoC).

Are there any tricks to get the nrf52 board to be able to use the Zephyr build chain from within a VirtualBox Linux machine? When ever I run ‘ninja -Cbuild flash’ the Jlink usb device disconnects from the virtual box.
