- nRF54H Series: Removed support for the reset command in the SecDom FW command version 1. This version of the command was not available for nRF54H EngC, and dropping support shouldn't influence these devices.
For EngB, you might get an error
SDFW reset handling is not implemented for SDFW commands version 1during programming if you are on an old SecDom FW version. You need to upgrade the SecDom FW version or use an older version ofnrfutil device, for example v2.8.3.
