I followed given steps to create new parameters, but when i connect my board to mission planner, I can’t see my parameter in parameter list.
I want to add parameter in parameter list of mission planner to update value from mission planner.

Steps i followed: [Add to Library method] (Adding a New Parameter to Copter — Dev documentation)
