nrfutil ARM64 cannot successfully flash an nRF52 series part. In this example I am trying to flash an nRF52840.
On the same system, nrfjprog works without issue.

The tested version is not required, and your J-Link version will most likely work fine. If you get issues related to J-Link with your devices, use the tested version.
Flash failure. --log-level trace does not seem to work to output more information:
