Amlogic S905 Source Code Published – Linux, U-Boot, Mali-450 GPU and Other Drivers

Amlogic has an open linux website where they regurlarly release GPL source code, and with Amlogic S905 devices coming to market, they’ve released a few tarballs at the beginning of the month including Linux 3.14 source code, U-boot source code, and Mali-450MP GPU kernel source code (obviously not userspace), as well as some other drivers for WiFi, NAND flash, PMU, TVIN, etc…
Amlogic_S905_Linux_MenuconfigLet’s get to the download links:

I quickly tried to build the Linux source. If you’ve never build a 64-bit ARM kernel or app before, you’ll fist need to install the toolchain. I installed the one provided with Ubuntu 14.04:


Now extract the tarball and enter the source directory:


At first I had a build failure due to a missing directory, so I created it, and use the default config for Amlogic S905/S912 (in arch/arm64/configs), before building the Linux kernel.


and it ended well:


So that’s a good starting for anybody wanting to work on the Android or Linux kernel…

Unrelated to Amlogic S905/Meson64, but I’ve also noticed some OpenWRT packages and rootfs  on Amlogic website that was released a little earlier this year. So either some people are using Amlogic Sxxx processors with OpenWRT, or Amlogic is working on a router chip that I missed. Probably the former.

Thanks to Olin.

Good news. But I wonder why the amlogic linux community is quite small compared with linux-rockchip and linux-sunxi.

My guess would be that a lot of community for Allwinner came from Cubieboard/truck or Olimex devices from the time there was only the RaspberryPi 1 and the Allwinner Chips were a lot more powerful. Now the market for little ARM boards is already filled (dominated by RPi2) so there is no need for more.

There is a decent AMLogic Kodi community – as AMLogic SoCs have much better Open Source video driver support than most other SoCs, along with the Raspberry Pi and Pi 2.

Allwinner and Rockchip are pretty much dead in Linux Kodi terms, with iMX6 and Exynos a little better but not as popular.

Now they still need to publish the matching userspace code. HAL for Android and lot of integration code.

libamplayer is really ffmpeg, so it’s GPL. Otherwise no way to use the VPU.

They should better make the complete git repo for Android SDK public, so one get a working complete build. Really no big secrets in there. Same patched code soup as Rockchip or Allwinner.

Big modding community > more popular > big sales. Old RK3066 was a big success because SDK leaked early. They don’t realize still.

Hi, it out of topic, but do you, or anyone have / know a list of the current SoC’s that have native Sata interface??
Thanks.

Well I had already tried that, of course, but did not find the info I want…. if you have a link, you’re welcome!!
Otherwise, your reply seems a little sarcastic… sorry!

If you refer to cheap stuff: http://linux-sunxi.org/Sunxi_devices_as_NAS#SATA_and_GBit_capable_ARM_alternatives (the actual limitations regarding A20 you also find in the linux-sunxi wiki: 45/200 MB/s write/read max.)

@Jean-Luc Aufranc (CNXSoft) First, I wanted to say thanks for your great articles, which I just discovered a few weeks ago! You seem to be an insider and expert if it comes to those to those ARM multimedia boxes. Right now I always read that they (mostly all) come with Android. Because this very probably will get no support/updates from the manufacturer after release, do those drivers make it possible to compile your own Android and so install a newer version, e.g. 6.0? There are Linux distributions besides Android like Ubuntu with X for the Odroid-C1. Do those drivers make… Read more »

This is excellent news, glad to see Linux make its way to the S905.

That means that one can probably not expect Android 6.0 on this generation of chips and wait for the next one?

Regarding “traditional” Linux (as Android is also a Linux version): Are the drivers enough to run X windows or Wayland? Then one could run Kodi via this way. And also run a browser and e-mail program. What I want is a Raspberry Pi like device with H.265 and HDMI 2.0/[email protected] Hz support 😀

Thanks for the info about building the kernel.

I’ve managed to run Ubuntu 14.04 headless arm64 Linux on the K1Plus box that runs off the memory card. I’ve produced a memory card image with some instructions. that you can find here:
https://app.box.com/s/cdp22zttsh058ulan4cnzmu196gxu28u

This makes K1Plus cheap arm64 Linux development box.

@Livetv The installation instructions are in my link above, just open the pdf file and read it. Also cnx-software published an article that explains more how to do the installation on another s905 tv box. The article is here:http://www.cnx-software.com/2015/12/06/how-to-run-headless-linux-on-amlogic-s905-devices-such-as-mini-mx-or-k1-plus/ There is a memory card image you can find on the link above which is ubuntu 14.04 distro. So you can install whatever software you want by typing ‘apt-get install …’ once you are logged in. Note, headless means there is no graphics enabled, just text console, but still it can be usefull to compile stuff, run servers or do some… Read more »

I followed the CNX article to run headless Ubuntu on my Tronsmart Vega S95 Telos. But ethernet doesn’t work (even with changed dbt.img).
So i followed your instructions (box.net) to create a new kernel.img. My problem is: I have no rootfs ramdisk. I need it for mkbootimg. Can you help me where to get?

I am right to assume that arm32 packages are not compatible with arm64 cpu, unlike x86_64 is able to run i386 binaries ? (i don’t have an arm64 box yet, ordered one this week). Then i have a couple of questions on those amlogic kernel sources : on their download server root (openlinux.amlogic.com:8000/deploy/) you can find a few tools and scripts, some are there to prepare you distro (deploy_ubuntu_14.04.sh) to build the kernel, but there are also gcc packages. Is it implied that we should use those specific gcc packages to properly build their kernel ? For example as i’m… Read more »

@Jean-Luc Aufranc (CNXSoft) i’m trying to build the latest source arm-src-kernel-2015-12-15-2c44a2727e and i am having some troubles. I’m building it for my s805 box (arm not arm64) so i was wondering after noticing your title “amlogic s905 source code published”, is it an s905 arm64 only source tree ? Seeing there is a meson32_defconfig file, i don’t believe that’s the case, but well is there a file list info document somewhere on their repository ? Using the same command format you use above, my arm build fails with “No rule to make target `dtbs’. Stop.” There’s one single dts file… Read more »

Hi guys, Related to this topic. I tried to compile some single modules for my Beelink mx64 to work with a DragonRise-based USB gamepad. I could compile the two needed .ko files OK but as soon as I try to load the second one (hid-dr.ko), the box hangs and there is NO indication of even loading in dmesg. Can anyone help me to show how I might diagnose please?

hi, Do “make menuconfig” in your kernel sources and go to usb section to built in all the usb converters and then with the option and compile the kernel. Do you have the sources from amlogic?

Guys, I have MXQ quick play that is running the Mini MX Plus ubuntu image from this thread. I’m using the DTB from my box and almost everything is working quite well. I am trying to get my TV remote to work with Linux. I’ve installed lirc and tried different options like “Linux input layer” and “Windows Media Center Transceivers/remotes” but none seem to work.

@Jean-Luc Aufranc (CNXSoft) Thanks CNXSoft. Apologies for the late response, I thought I’d responded to your suggestions, but coming back here today I see I had not. Yes, CONFIG_IR_MESON was enabled and loaded, it turns out that codes from IR remotes of some devices (like a sharp TV) were not picked up by MXQ, whereas IR events sent by other remotes like a Sony TV, remote of Table fan etc were picked up. I had assumed that all IR remote codes will be picked up by all IR receivers , whether they act on it or not is a different… Read more »
