We’ve seen in the past AMLogic sometimes pushes some updated GPL software releases on their Open Linux website. So I went to have a look a few days ago, and to my surprise they already had instructions to download and build Android 4.4 for AMLogic M802 (Tablet) and S802 (STB), “user’s guides”, as well as links to reference schematics for the tablets… Nice!!!
I started with 4.4_ReleaseInfo for “Mbox” (S802), which explains how to get the SDK release on 2014-01-27 (kk-amlogic-20140127):

1 2 3 4 |
repo sync repo init -m openlinux_kk-amlogic_20140127.xml repo sync |
Unfortunately the joy stopped right there, as you need to send your SSH public key to your representative. I’ve just done that, and sent an email to support [at] amlogic.com, and mbox-android [at] amlogic.com on Sunday, and I have yet to gain access. I’ve found the “mbox-android” email in from Mbox page (similar to screenshot above) in a field right of “reference schematics” column, which has been removed since then. I’ve just noticed you actually need to fill a form with your company details to potentially get approval.
I’ve also found out that links to schematics and “user’s guides” all ask you to “please contact your sales window”, so there’s basically nothing available from this “open source” website, except the GPL source code directory last updated in April 2013, and there’s obviously nothing about S802/M802. There’s also documentation available publicly or via NDA / SLA depending on the doc. Finally a Tools page is available, but with all information referring to files in the SDK.
The media box reference platform appears to be called “AML-M802 K200” with either 1 or 2GB RAM. and there appears to be two tablets reference designs: M802 K100 and M802 K101. There’s also a TV section for AMLogic T802?, but it’s empty for now.

A bit better. I should have gone down in the directory structure… I only looked at the GPL directory.
I can see they also have r3p2 drivers for Mali-400 – http://openlinux.amlogic.com:8000/download/ARM/gpu/gpu-2013-12-20-88078c9f9f.tar.gz
Is it usable in Linux?
@Jean-Luc Aufranc (CNXSoft) Mali has 2 set of drivers 1. Framebuffer only – gpu-2013-12-20-88078c9f9f.tar.gz 2. X.org only for x.org version you can try https://github.com/linux-sunxi/sunxi-mali libv(co author of opensource drivers ) is big collector 🙂 But as I wrote on this page. don’t expect good performance from x.org mali drivers. https://github.com/limadriver/xf86-video-mali But if you really want to play with mali on amlogic boards you can fallow howto-s on http://linux-sunxi.org/Main_Page http://linux-sunxi.org/Binary_drivers for x.org you can try this https://github.com/ssvb/xf86-video-fbturbo raspberry pi and Allwinner SOC add support for 2D acceleration of x.org amlogic has some 2D acceleration as far as I know (for window… Read more »

I think folks from odroid use r3p2 , look @ http://lkcl.net/reports/odroid-u2.html ….

@m][sko
However, it does not appear to build.
arch/arm/mach-meson8/include/mach/system.h:40:5: error: implicit declaration of function ‘WRITE_MPEG_REG’ [-Werror=implicit-function-declaration]
WRITE_MPEG_REG(VENC_VDAC_SETTING, 0xf);
@Jean-Luc Aufranc (CNXSoft)
Looks OK now… Just my mistake…
Is there something of this I can use for debricking my onda v975m.
missing usb_spl.bin and a config.xml file for recovery.
only contact to tablet is by amlogic usb burning Tool. (as m8. tools driver working)
normal recovery by m sd Card is by a .aml file with some Linux command.
but nand total empty or corrupt. so no go 🙁
Please help!
hi guys, there were updated sources at the openlinux site on 14th March.
@gizmomelb
Thanks. It was mentioned in a later post: http://www.cnx-software.com/2014/03/10/amlogic-gpl-source-code-release-kernel-3-10-u-boot-and-drivers-wi-fi-nand-tvin-mali-gpu/
@Jean-Luc Aufranc (CNXSoft)
ahh awesome, thanks mate – the newer build instructions will come in handy.
