A customized rk3399 Linux aarch64 collection repository

Target

• VAMR Rock960 board ( or others too )
  • 96board, Rock960A/B and C ( model C is still testing )
  • Enhanced Kernel 4.4.194 ( now upgrading to 5.10 )
  • Debian 11, bullseye ( completed upgraded )
  • exFAT support in kernel 4.4.194
    • exFAT source by ater97

First initializing submodules

• do these sequence at first time,

   $ git submodule init
   $ git submodule update
  

• it may takes long time.

Make prebuilts + prepare cross compiler

• Create these directories

  prebuilts/gcc/linux-x86/aarch64/
  

• And download gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu from here.
• Extrct gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz to prebuilts/gcc/linux-86/aarch64.
• Then once you need run this:

  export PATH=$PATH:$PWD/prebuilts/gcc/linux-x86/aarch64/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin
  

Build kernel first ( before u-boot )

• Rock960A/B

   $ build/mk-kernel.sh rock960ab
  

• Rock960C

   $ build/mk-kernel.sh rock960c
  

Then build u-boot ( after kernel )

• Rock960A/B

   $ build/mk-uboot.sh rock960ab
  

• Rock960C

   $ build/mk-uboot.sh rock960c
  

Build rootfs

• First time you need to do this for making a file 'linaro-bullesys-alip-${datetime}.tar.gz'.

   $ cd rootfs
   $ ./mk-base-debian.sh
  

• You can skip above step if have tar.gz file.
• Then create debian bullseye base updates for Rock960 board,

   $ ./mk-rootfs-bullseye.sh
  

• This sequence extract base tar.gz to binary directory, and copying overlay contents into binary.
• Then final step for this

   $ sudo ./mk-image.sh
  

• This step creates linaro-rootfs.img file.

Make a complete system image.

• Before do this, check these files exists:
  1. boot.img ( uboot and kernel )
  2. linaro-rootfs.img
• Then do this,

   $ build/mk-image.sh -c rk3399 -t system -r rootfs/linaro-rootfs.img
  

• Then should flash system.img to zero address via rkdeveloptool.
