El SDK de Rockchip para Debian

A continuación están las instrucciones sobre cómo construir una imagen Debian para el ROCK Pi 4.

Obtener el código fuente

Necesitarás Git para usar múltiples repositorios git en la construción de la imagen.

Instala Git si no lo tienes.

   sudo apt-get update
   sudo apt-get install git

Clona el código fuente

   git clone --recursive https://github.com/radxa/rockchip-bsp.git

Bájate

   build  kernel  README.md  rkbin  rootfs  u-boot

Estos directorios contienen instrucciones para:

  • build:
    • Ficheros de script y ficheros de configuración para compilar u-boot, el núcleo y el rootfs.
  • kernel:
    • El código fuente del núcleo, la versión actual es la 4.4
  • rkbin:
    • Binarios precompilados de Rockchip, se incluye el cargador de primera etapa, y el Firmware ATF(Arm Trustzone Firmware).
  • rootfs:
    • Bootstrap es un rootfs basado en Debian, soporta las arquitecturas armhf y arm64 de Debian Jessie y Stretch.
  • u-boot:
    • u-boot como segunda etapa de cargador de arranque

Instalar el toolchain y las demás herramientas de construcción

   sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev mtools

Compilando u-boot

   ./build/mk-uboot.sh rockpi4b     #Para ROCK Pi 4 Modelo B

Las imágenes generadas se copiarán en la carpeta out/u-boot

   ls out/u-boot/
   idbloader.img  rk3399_loader_v1.12.112.bin  trust.img  uboot.img

Build kernel

Build kernel with default rockchip_linux_defconfig

   ./build/mk-kernel.sh rockpi4b    #For ROCK Pi 4 Mode B

Change kernel config(optional)

Optionally, if you want to change the default kernel config

   cd kernel
   export ARCH=arm64
   export CROSS_COMPILE=aarch64-linux-gnu-
   make rockchip_linux_defconfig
   make menuconfig
   cd ..
   ./build/mk-kernel.sh rockpi4b    #For ROCK Pi 4 Mode B


You will get the kernel image and dtb file

   ls out/kernel/
   Image  rockpi-4b-linux.dtb

Make rootfs image

To build 32bit rootfs:

   export ARCH=armhf

To build 64bit rootfs:

   export ARCH=arm64

Building a base debian system by ubuntu-build-service from linaro.

   cd rootfs
   sudo apt-get install binfmt-support qemu-user-static
   sudo dpkg -i ubuntu-build-service/packages/*        # ignore the broken dependencies, we will fix it next step
   sudo apt-get install -f
   RELEASE=stretch TARGET=desktop ARCH=$ARCH ./mk-base-debian.sh

This will bootstrap a Debian stretch image, you will get a rootfs tarball named linaro-stretch-alip-xxxx.tar.gz.

Building the rk-debain rootfs with debug:

   VERSION=debug ARCH=$ARCH ./mk-rootfs-stretch.sh  && ./mk-image.sh

This will install Rockchip specified packages and hooks on the standard Debian rootfs and generate an ext4 format rootfs image at rootfs/linaro-rootfs.img.

Combine everything into one image

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

This will combine u-boot, kernel and rootfs into one image and generate GPT partition table. Output is

   out/system.img

Flash the image

For normal users, follow instructions here. You will need the generated out/system.img only.

For developers, flash from USB OTG port, follow instructions here. You will need the flash helper rk3399_loader_xxx.bin and generated out/system.img files.
