Pixhawk HITL Firmware

Hey there! I need to implement HITL simulation using PixHawk1 and Mission Planner. I can’t find the correct firmware for this despite several hours of online search, does anyone has it or knows where I can find it? Thanks a lot!

You might be able to get Sim on Hardware working on a Pixhawk1. Check out the docs here. Simulation on Hardware — Dev documentation
