I strictly followed the tutorial in the document to develop
(docs.nordicsemi.com/.../ug_nrf54h20_gs.html
but the west flash still failed in the end. Here I record my operation process.
1.ncs version(with west update success)
2.the sample zephyr/samples/sysbuild/hello_world also build success.
3.some nrfutil command
4.flash always failed.
So please help to solve the flash issue.
