You can program the Nordic Thingy application and network core firmware over USB by using MCUboot, which is a secure bootloader that you can use to update applications without an external debugger. MCUboot bootloader is enabled by default for the Nordic Thingy prototyping platforms in the Kconfig.defconfig files of the board, available in either the nRF Connect SDK or Zephyr.
You can follow this procedure to update the preloaded firmware on the Nordic Thingy prototyping platforms using the precompiled application firmware available from the Nordic Semiconductor website for the platform of your choice:
See the CONTENTS.txt in the downloaded ZIP archive for the description of the firmware files and their usage.
To program the Nordic Thingy prototyping platforms, you can use one of the following options:
- Using a USB cable
- Using an external debug probe
Note
Do not unplug the Nordic Thingy prototyping platform during the programming process.
