ARM – Odroid U3 to 3.19-rc7 – Fan ‘Fixed’?

Updated the Odroid U3 to Kernel 3.19-rc7, from

Had to ‘refresh’ the config, by # make exynos4412_odroid_defconfig, and then (re)enable selinux etc…

One feature is that the CPU fan no longer runs constantly, but I need to do more tests, to see if it is now capable of running at all..    The temperature is OK, at the moment…

There are a series of patches being developed to provide U3 fan control:  but these are still not (yet) finalised?

  1. Hi!
    Can you share particular kernel install process, including compile options, generating dtb, etc for Odroid-U3?
    thank you!

  2. Hello Robert, the latest version of the hwmon patchset is here:

    There are some comments though by the hwmon/thermal maintainers and you’re probably going to see some more revisions of the code. Anyway, if you want to speed up the process then you can always post on the ml if the patchset works for you. Maintainers are more inclined to merge stuff that more people have actually tested (and I can’t do this, since my board doesn’t have/need a fan).
