Since Google has changed their way of releasing new version of Android, as they are now taking input from developers using preview releases, we’ve known the main changes in Android 7.0 for a while including multi-window support, improved security, virtual reality support, Vulkan API, a new JIT/AOT compiler, and so on. The company has now made it official, and released Android 7.0 earlier today. Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, Nexus Player, Pixel C, and Android One smartphones will receive an OTA update with the new firmware, and some other phones enrolled in Android Beta program will also get Android 7.0, but older Nexus 5 and Nexus 7 devices won’t. Google and LG also unveiled the upcoming LG V20, the first smartphone to ship with Android 7.0. Few details have been provided so far The LG V20 builds upon the premium and rich multimedia smartphone experience of last […]
Amlogic Releases Linux 3.14 Source Code for S905X, S905D, and S912 Processors, Has Started Working on Linux 4.4 / Android 7.0
Amlogic has just released buildroot with Linux 3.14 with support for Amlogic S905X (p212 board), S905D (p230 board), and S912 (Q200 board) processors, and the company appears to have started working on Linux 4.4 likely for future support for Android 7.0. You can check the source code as follows:
1 2 3 |
wget -c http://openlinux.amlogic.com:8000/download/ARM/filesystem/arm-buildroot-2016-08-18-5aaca1b35f.tar.gz tar xf arm-buildroot-2016-08-18-5aaca1b35f.tar.gz cd buildroot |
If you have the wrong toolchain the code won’t build (See comments section). So I installed several toolchains provided by Amlogic (all may not be needed) in /opt:
1 2 3 4 5 6 7 8 9 10 |
wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-arm-linux-gnueabihf.tar.gz wget -c http://openlinux.amlogic.com:8000/deploy/arc-4.8-amlogic-20130904-r2.tar.gz wget -c http://openlinux.amlogic.com:8000/deploy/CodeSourcery.tar.gz sudo tar xvf gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar -C /opt sudo tar xvf gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.bz2 -C /opt sudo tar xvf arc-4.8-amlogic-20130904-r2.tar.gz -C /opt sudo tar xvf gcc-linaro-arm-linux-gnueabihf.tar.gz -C /opt sudo tar xvf CodeSourcery.tar.gz -C /opt |
I also downloaded a shell script to add the toolchains to my path:
1 2 |
wget http://openlinux.amlogic.com:8000/deploy/TOOLSENV.sh source TOOLSENV.sh |
Once toolchains are setup, you can select one of three boards config (Q200 / S912 as example) and start building the code:
1 2 3 |
sudo apt install build-essential make mesongxm_q200_release_defconfig make |
If you are interested in S905X or S905D instead, use respectively mesongxl_p212_release_defconfig or mesongxl_p230_release_defconfig. I built both S912:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |

Android 7.0 is Finally Codenamed Android Nougat, Release Scheduled for this Fall
Despite Nutella clearly having won the popular vote, Google has finally chosen a different name most likely for trademark reasons, and Android 7.0 will be called Android “Nougat“. Since Google had already released several Android N previews, we’ve already known the main changes for some times including better virtual reality support, multi-window support, improved security, faster performance thanks to Vulkan API and new JIT compiler, and so on. Smartphone and tablet manufacturers will release hardware and firmware updates based on Android 7.0 starting this fall, and some TV boxes will likely start to run Android Nougat a little later, probably in 2017 and beyond.
