>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
