I had tried to update the Odroid U3 to Kernel 4.0-rc5 – using the patched source from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.0.y – a few days ago, but the boot failed: hub 1-3:1.0: 3 ports detected INFO: rcu_sched detected stalls on CPUs/tasks: { 0} (detected by 1, t=4202 jiffies, g=-255, c=-256, q=2) Task dump for CPU 0: swapper/0 R running 0 … Continue reading →

As there is no later version of the Odroid-specific 4.0 kernel source available yet, I decided to test with the standard 4.0-rc3 from kernel.org, but the U3 booted – and then Panic‘d.. ……………………….. EXT4-fs (mmcblk0p3): mounted filesystem with ordered data mode. Opts: (null) VFS: Mounted root (ext4 filesystem) on device 179:3. devtmpfs: mounted Freeing unused kernel memory: … Continue reading →
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 →
