Ardupolit setup

I’m trying to setup APM 2.8 but mapplanner tells me my board has been retired. can anyone help me please

Ignore that and just let it install the default firmware. It will be 3.2.1 which is the last version supported for that old out-of-date Flight Controller.

After downloading the latest version I get a note that says please update some older library dills are causing problems. Method not found.:Void Mission Planner.Arduino.IArduinoComms.set_Stop Bits( system IO. Ports. Stop bits
