A95X (S905X Variant) Source code, toolchains and build system to build:

Linux 3.14 Kernel Image - Image
Boot Image with kernel & modules - boot.img
System Device Tree - gxl_p212_2g.dtb, dtb.img
RootFS Tarball - rootfs.tar.gz
RootFS EXT2 Image for dd - rootfs.ext2.gz
Uboot for eMMC boot - u-boot.bin
Uboot for SD boot - u-boot.bin.sd.bin

Ive only tested onn Ubuntu LTS 14 & 16. If you can give me feedback on other distros I can make changes to make it work with yours normally. Only real requirements are for x64 host with i386 libs available.

See Readme in toolchains folder for toolchains

OR

Run the setup.sh script to configure your build environment

Change into the buildroot folder

Setup build env vars

source setup-build-env.sh

Generate config for your device

For A95X-2G: make s905x_a95x_2g_defconfig

For A95X-1G: make s905x_a95x_1g_defconfig

For Generic S905X: make mesongxl_p212_release_defconfig

To nose about: make menuconfig

Just fire off make, make brew and sunday dinner

Use -jX for multi threaded compiling to icrease speed, X=number of cpu cores or hw threads available for max performance

make

make -j4

Important output will be in output/images

1. Create an SD card with one partition in ext2 format.

2. Copy boot.img, rootfs.tar.gz to this partition

    sudo cp output/images/boot.img /media/sdcard
   
    sudo cp output/images/rootfs.tar.gz /media/sdcard
   
    sudo sync
   

3. Extract rootfs.tar.gz on SD card

    cd /media/sdcard
   
    sudo tar zxvf rootfs.tar.gz
   
    sync
   

4. Write uboot to SD card

    sudo dd if=output/images/u-boot.bin.sd.bin of=/dev/mmcblkX bs=1 count=442
   
    sudo dd if=output/images/u-boot.bin.sd.bin of=/dev/mmcblkX bs=512 skip=1 seek=1
   
    sudo sync
   

5. Access UBoot You'll need to access the serial console and enter into the UBoot prompt. On the Nexbox A95x S905x, there are 4 exposed test points next to the USB ports. The "top" pin (in reference to the text on the case and marked by the arrow on the board) is ground, below that is RX, followed by TX. The console runs at 115200 baud and you have to hold down enter while it's booting to enter the UBoot console.

6. When running into uboot, execute run bootsdcard under the prompt:

    env default -a
   
    env save
   
    run bootsdcard
   

7. (optional) To make this the default behavior (be careful, especially if you're changing the EMMC bootloader!), you can run the following commands at UBoot instead:

    env default -a
   
    setenv bootcmd "run bootsdcard"
   
    env save
   
    run bootsdcard
   

Warning! This will fuckup whatever is on the device, literally set that little bad boy on fire. DO NOT DO THIS

** Before going any further go into the recovery folder and read the Readme.md **

1. Create an SD card with one partition in vfat format

2. copy boot.img and root file system to SD card

    cp output/images/u-boot.bin /media/mySD
   
    cp output/images/boot.img /media/mySD
   
    cp output/images/rootfs.tar.gz /media/mySD 
   

Insert SD card into your platform and reboot into uboot. Replace original uboot with the new one under uboot prompt:

mmcinfo

fatload mmc 0 ${loadaddr} u-boot.bin

store rom_write	${loadaddr} 0 120000

fatload mmc 0 ${loadaddr} gxl_p212_2g.dtb

store dtb write	${loadaddr}

reset

3. With new uboot burned on your platform, enter uboot prompt again and execute run bootupdate

    env default -a
   
    env save
   
    run bootupdate
   

4. System will automatically write kernel to boot partition and extract rootfs.tar.gz to system partition.

5. Reboot platform.

6. System will boot up with kernel and root filesystem on EMMC/NAND.
