Examples build

cd nrf/v2.3.0/zephyr/samples/sensor/bme680
>west build -b thingy53_nrf5340_cpuapp

• nRF Desktop Programmer
  • keep internal sw2 while power on with sw1 see Updating through USB
  • on success a new port is detected
  • use dfu_application.zip see MCUboot output build files
• restore example application firmwa with the same procedure with binaries available on the Nordic Thingy53 downloads
