Just installed the kernel.org version of kernel 3.18-rc4 on the Odroid U3, and this time it completed the boot, but still had a ‘tombstone’: …………… cam-power-domain: Power-on latency exceeded, new value 413333 ns cam-power-domain: Power-on latency exceeded, new value 564291 ns Unable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = ee328000 [00000010] *pgd=00000000 … Continue reading →
I had been trying to get USB working with 3.17 and 3.18-rc kernels on my Odroid U3 for some time, and had been looking for fixes in the source code. It turned out that I was looking in the wrong place – and a clue to this was the lack of any mention of the problem on … Continue reading →
Tried the latest kernel.org 3.17 kernel with my Odroid U2, and managed to get it to boot successfully, but USB still doesn’t work, which is a show-stopper, as the Ethernet adapter is a USB-connected device.. Start with # make exynos_defconfig, and then select arch/arm/boot/dts/exynos4412-odroidu3.dtb when merging with zImage, etc… [ 0.000000] Booting Linux on physical CPU 0xa00 … 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 →
