Android6 for Trizeps-VII

Kernel

Kernel The Android 6 Support is based on the FSL 4.1.15 Kernel (device tree based)

U-Boot

U-Boot 2016 is used. U-Boot is able to load the device tree from the root Directory of MISC (partion 8, vfat)): oftree.dtb (solo/duallite) or oftree-mx6q.dtb (dual/quad). The MISC Partition contains device trees for multiple board/display combinations. You can just copy the right oftree.dtb and oftree-mx6q.dtb pair to the MISC-root Folder.

MISC Partition

The Android Images contain a FAT based Parttion which is labeled as MISC. It can be used to configure device tree, boot shellscript, bootanimation and build.prop.

The FAT based „MISC“ Device Partition can be used to adapt the Keith & Koep Android 6 OS Image to custom requirements. The MISC partition will be mounted on the device during runtime as /oem and will be mounted as read only. With the shell command „remount.sh“ the system and oem partitions will be remounted as read/write. So the oem is able to modifiy the filesystem to the device requirements without rebuilding the OS-Image.

A Configuration may contain:

  1. oftree.dtb device tree for Solo/Dualite Processors
  2. ofree-mx6q.dtb device tree for Dual/Quad Processors
  3. init.oem.rc (opt) executed at boot-time as root
  4. build.prop (opt) delivers default boot properties this exchanges /system/build.prop
  5. media/bootanimation.zip (opt) Bootanimation overrides default boot animation

To ease configuration you can setup the files by yourself. The DTB folder contains device trees for different boards. There are other Folders for SCRIPTS and PROPS and the is a CONFIGS Folder containing Folders with complete configurations. You can easily copy the content of one CONFIGS/xxx folder to MISC root to activate the custom configuration.

Try and have fun !!!!
