I've tried to upgrade a quad from 3.4.6 to 3.5.0-rc7 but i could not make the board boot. After the upgrade, it keeps repeating the sound "New IO board firmware loaded successfully". If I revert the firmware it boots OK. I tried to load the correct binary for ardupilot-v1 but it gave the same error.
Is the new code supposed to work on this board? If not, is there any plans to make it work? I´m just asking because I need to know if I will need to replace the px4 controller...
Thanks ! Fernando
