Description

Tested on a J-Link Base Compact, it seems that FINE requires special handling and will somehow hang the probe when selected.

I don't really care about FINE, and don't have any chips that speak it, so I'll just note this in the docs for now.

Contributor guide

Research direction
Investigate the J Link protocol for the Fine interface to understand why selecting it hangs the probe. Check the SEGGER documentation or source code for special handling of the Fine interface. Consider adding a workaround or error handling to prevent the hang.
