I am using nRF52840dongle and trying to flash the Blinky sample application provided in Zephyr.
Blinky: docs.zephyrproject.org/.../README.html
I had referred the programming instruction mentioned at given link https://docs.zephyrproject.org/latest/boards/nordic/nrf52840dongle/doc/index.html
I had tried to program the dongle by using method mentioned in option 1 which uses nrfutil. Successfully able to complete at Step 3 which is "Package the application for the bootloader using nrfutil". It failed at step 4
Issue:
Flashing Failed by giving below command
nrfutil nrf5sdk-tools dfu usb-serial -pkg blinky.zip -p COM22
Error:
zephyrproject>nrfutil nrf5sdk-tools dfu usb-serial -pkg zephyr\blinky.zip -p COM22

pc_ble_driver_py.exceptions.NordicSemiException: Response Code OperationNotPermitted
[6640] Failed to execute script '__main__' due to unhandled exception!
The response code does not give much information. What could be the reason ?
Additionally, Tried to flash using command west flash. That also failed with an FATAL ERROR: required program nrfjprog not found; install it or add its location to PATH
