Now Amlogic SoCs of the Meson family are supported upstream :
- Meson8b : s805
- Meson-GX : s905 (GXBB) s905x/S905d (GXL) s912 (GXM)
- Meson AXG : a113d
This Yocto/Openembedded will help building images for these SoCs using the lastest uptream linux branch.
Create a home repository for the build :
$ mkdir amlogic-bsp
Checkout Yocto/Poky :
$ cd amlogic-bsp
amlogic-bsp$ git clone --depth 1 git://git.yoctoproject.org/poky -b thud poky
Checkout meta-meson :
amlogic-bsp$ git clone https://github.com/superna9999/meta-meson.git meta-meson -b thud
Initialize environment :
amlogic-bsp$ TEMPLATECONF=../meta-meson/conf
amlogic-bsp$ source poky/oe-init-build-env
amlogic-bsp/build$ cp ../poky/meta-poky/conf/local.conf.sample conf/local.conf
or :
amlogic-bsp$ source poky/oe-init-build-env
amlogic-bsp/build$ bitbake-layers add-layer $PWD/../meta-meson/
This layer aims to support all mainline supported boards, but some of them have a vendor U-Boot loaded on the eMMC and can only be booted by pressing the "update" button.
The libretech-cc, hardkernel-odroidc2, amlogic-p212 and khadas-vim are fully mainline sdcard images, with mainline U-Boot and mainline Linux with a single ext4 partition. To boot this image the eMMC u-boot must be disabled by erasing the first sectors of the eMMC or removing it for libretech-cc and hardkernel-odroidc2 boards.

Experimental A113d machine :
- amlogic-s400 : complete bootable .wic eMMC image with mainline U-boot
Images types available (in addition of standard Poky/OE images) :
- amlogic-image-headless-sd : to flash on an eMMC or SD-Card
- amlogic-image-headless-initrd : to load as ramdisk
- amlogic-image-sato : Graphical images with X11 and Sato environment to flash on an eMMC or SD-Card
Standard types are :
- core-image-base : Basic console image with boot logo
Building SD image for all S905 and S905X and S912 machines :
amlogic-bsp/build$ export MACHINE=amlogic-s9xxx
amlogic-bsp/build$ bitbake amlogic-image-sato
A .wic image will be generated in the tmp/deploy/images/$MACHINE/ directory.
This Image contains a FAT32 BOOT partition will the kernel uImage and .dtb, compatible with Amlogic U-Boot already flashed on your device.
For the amlogic-p212, khadas-vim and libretech-cc, Mainline U-Boot is automatically installed in a single ext4 partition .wic image in the tmp/deploy/images/$MACHINE/ directory.
Flash the .wic file with the Etcher tool from https://etcher.io/
Or for the connoisseurs :
You will be able to dd the image onto the raw SDcard like :
sudo dd if=tmp/deploy/images/libretech-cc/core-image-sato-libretech-cc.wic of=/dev/mmcblk0
