This guide provides information which will help you get started with rockchip opensource linux. If you have any questions, please report to us on github project issue page.

We are providing 2 kind of rootfs. prebuilt Debian and Buildroot. You can choose the way you prefer. 

  • Buildroot: An easy and small embedded Linux system. Recommend for your product development. 
  • Prebuilt Debian: A generic desktop Distro. Only for your evaluation. 

You will need below firmware/image for a full Linux OS and flash them to different locations:

  • Rockchip miniloader: This is the first level boot loader
  • U-Boot: This is the second level boot loader
  • Trusted: ARM Trusted Firmware
  • Resource: Kernel dtb, It is only used for development. 
  • Kernel: Kernel image, It is only used for development. 
  • Boot: It is Android boot image format. Pack kernel dtb and image to one partition. Use it for production. 
  • System: Rootfs
