Hardkernel announced the Linux kernel 4.9.11 support for the ODROID-XU4 and XU3 platforms in late February and we started a debugging party. After ten weeks of debugging party with our community members, we are proudly releasing a new Ubuntu image based on latest Linux kernel 4.9.27 LTS.
We’ve improved and added new features UASP, UHS1 mode, IRQ balancing, HW mouse cursor, HW RTC Alarm, overlayfs, faster armsoc DDX, multi-touch screen and much more. You can find over 300 commits in our GitHub history.
We’ve packed all the new updates into a new OS image for every XU4 users. This official Ubuntu OS image is available on this link.
We will keep improving and update the Linux OS since we still have some issues.
Note that there is no reliable way to update the Kernel to 4.9 from 3.10.
So please freshly install the new OS image after backup your data.
