In my experience the 32bit board it is not working properly. I have gimbals with 8 bit boards working with RED Epic fine, but the 32bit boards just go crazy. I had one working more or less ok but I switched it off and after 2 hours switched it on again and it went crazy. Couldn´t get back to normal ever again. Surely there are problems with the boards of FW.
It's easy you can do it via automatic update but it works only on windows because the process launches some .exe files (i have a mac and i installed windows xp on vmware). press check and select the firmware from the dropdown menu it worked for me
