Updated the Odroid U3 to the latest version of odroid-3.19.y (# git clone -b odroid-3.19.y –single-branch https://github.com/tobiasjakobi/linux-odroid ). After checking that all the pwm-fan and temperature options were selected in the kernel config, I set ‘Default Thermal governor‘ to ‘step-wise‘. After compiling/installing, I tried some more tests: Using ‘stress’ to raise the temperature: # stress –cpu 4 … Continue reading →
Updated the Odroid U3 to (patched) Kernel 3.19, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Thanks to work by tobiasjakobi, this now includes the preliminary patches – updated for 3.19 – for fan control on the Odroid U3, originally posted by Lukasz Majewski at http://www.spinics.net/lists/linux-samsung-soc/msg42259.html So, (on a Fedora 21 system) you can now control the fan, as follows: # echo “0” … Continue reading →
This is a workflow for compilation of a kernel + device tree for the Odroid U3. There are other ways of doing this, but this one works, for me.. Compilation works fine on the device itself, so no need for cross-compilations.. This is for a device with root filesystem and boot partition on one SDcard.. Source from: … Continue reading →
Updated the Odroid U3 to Kernel 3.19-rc7, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y 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 … Continue reading →

I had been frustrated by the apparent inability of the suppliers to provide anything other than an obsolete Ubuntu-centric 3.8+ kernel for the Odroid U2, and other kernels I had tested were somewhat ‘incomplete’… I finally managed to get a 3.17-r3 version from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.17.y This now includes the necessary ‘bits’ for the U3, which is functionally identical … Continue reading →
