Hello,
We recently upgraded our application to use NCS version 3.0.1 and have not been able to flash firmware onto our nRF54L15 boards. We are running into the same issue as described in this thread: Flash nRF54L15DK with Toolchain 3.0.1 and SDK 3.0.0 fails
However, after updating nrfutil, its submodules, and our JLink drivers, we have not been able to resolve the issue. The error raise during flashing and the versions of nrfutil and its submodules are pasted below. We are not able to flash the nRF54L15 dev kit as well as our custom nRF54 devices. We did update the JLink driver to versions 8.12, 8.18, and the latest 8.46, but that had no effect on the issue.
Please let us know if there are any areas where we should look to resolve this issue. We are unclear where we would need to provide more information for the 'Application core revision info'.
Thank you

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. bvyates@CSCO-W-PW05PMKJ:~/co/amulet6/amulet$
