The following command programs the device with serial number <serial_number> with the firmware from the path/to/firmware.hex file:
nrfutil device program --firmware path/to/firmware.hex --serial-number <serial_number>
Tip
Run nrfutil device list to find the serial number of the target device.
Note
The program subcommand does not write the OTP memory region (OICR) on nRF54H Series devices. Use device otp-write for OICR.
