ARM – Odroid U2 – 3.17 Boot, but no USB..
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…

As this is standard kernel.org code now, the fix should be easier to investigate, given time.!

Interested to hear when you get this working! I subscribed to this thread
Me too, please post it if works.. Iam trying too, cheers
It seems a lot of the code for the Odroid/Exynos is still work-in-progress, and some patches sent to kernel.org are being rejected as ‘incorrect’.. The exynos-ehci error is still the same on kernel 3.18-rc3, although I can’t yet get that version to boot completely (fails to an emergency shell).

Thanks :)
