How to install the firmware compatible with ERB?

Hi,

How do you upload the new firmware (ArduCopter-octa-v3.3.3-ERB.px4 for instance) in Navio+? I tried to use Mission Planner (Load Custom Firmware) but I got the error: ‘No Response from Board’.
How do we have to connect the board while updating? Is it udp ok?

Thank you for all your help.

Hi! .px4 firmware is for Pixhawk only. Firmware on Navio is installed using deb packages or binary files. Latest versions from http://firmware.ardupilot.org/ have ERB support. Download the firmware for your frame, copy it on Raspberry Pi, make it executable and then run.
