#Linux kernel 4.4 upgrade#

The new kernel will remain in the unstable repos for a couple of weeks, and the team plans to release the new upgrade to the stable repos by the end of the month. Please stay tuned,” Canonical’s Joseph Salisbury said in his regular newsletter. “We have rebased our unstable kernel repo to v4.4 and will follow suit in our Xenial repository shortly and upload it to the archive. The next Linux kernel in line will most likely land in about two months, so the Ubuntu team wouldn’t have time to integrate it anyways. The fact that Ubuntu 16.04 (Xenial Xerus) will be powered by an LTS kernel was a no-brainer, but it’s nice to finally see it happening. They usually did this after a few maintenance versions were already released, but knowing ahead of time helps developers who want to adopt an LTS for their distro. The kernel developers and maintainers have started to do things a little bit differently and they have started to announce which version of the kernel will be an LTS before the launch. The team has been tracking the 4.4 branch for quite some time, and they had almost all of the RC versions, so it was only natural to get the stable 4.4 as soon as it made an appearance. Linus Torvalds released a new stable version of the Linux kernel just a few days ago, and the Ubuntu developers have been quick to integrate it into the latest build of Ubuntu 16.04. Add the following lines at the end of file Ubuntu Linux kernel team has announced that the Linux kernel in Ubuntu 16.04 LTS has been upgraded to version 4.4, the latest stable release made available. To enable console ttyS2, you need to enable uart2 node. But due to uart2 is disabled by default in file rk3328-rock-pi-e.dts, there will be no more system logs on the screen. If you read the kernel command line of system log, you will find that the default console is ttyS2 (1500000n8). If your ROCK Pi E system supports Ethernet/WiFi and SSH, you can access ROCK Pi E via SSH.

With an USB to TTL serial cable connected with UART2 pins (pin#10, pin#8, ping#6 on 40-PIN Header) on ROCK Pi E, the last one line of system logs is shown as follows.

Reboot and you will have the new kernel booting.įAQs 1.I have built one ROCK Pi E system image using rockchip-bsp SDK. The generated packages are(the kernel revision name maybe different): Make bindeb-pkg -j8 LOCALVERSION=$lv KDEB_PKGVERSION=$debv

The kernel package build can pack the kernel, device tree, modules and firmware into Debian packages, which makes it easier to install on the ROCK Pi E.įirst, setup the version number, make sure the format is right.Įxport build_id='999' # make sure it's big enough so that our kernel is the newest. The built targets we are interested are arch/arm64/boot/Image and dtb file arch/arm64/boot/dts/rockchip/rk3328-rock-pi-e.dtb. If you need to build kernel modules that are not in the default config, you can select it in menu config

Below is how to build it on a X86 Linux host PC.īranch stable-4.4-rockpie supports ROCK Pi E board.

The vendor kernel is based on the Rockchip 4.4 kernel with hardware support for ROCK Pi E. This guide describes how to build verdor kernel (Rockchip 4.4).
