4 Software Guide
This chapter provides instructions for compiling and deploying the BSP (Board Support Package) software to
the Q7 module.
4.1 Architecture Overview
The BSP consists of several parts. They run on different parts of the CPU and each play their role in the boot
process. Because the CPU contains cores running different instruction sets (ARMv6-M and ARMv8-A), two
different compilers are needed. The table below list the parts and their instruction set.
The next section explains how to install suitable cross-compilers for both instruction sets.
The section "Compiling Linux Applications" provides guidance for compiling user-space applications for the
RK3399.
4.2 Prerequisites
You need a recent x86_64 Linux installation to run the cross-compiler on and at least 10GB of disk space. The
cross-compiler requires libc version 2.2.5. Distributions shipping this version are, among others:
• Ubuntu 16.04 "Xenial"
• Debian 8 "Jessie"
• Debian 9 "Stretch"
We recommend Debian 9 "Stretch" or Ubuntu 16.04 "Xenial". Please install the following packages to set up
the common build infrastructure:
sudo apt install device-tree-compiler u-boot-tools build-essential git bc debootstrap
static libssl-dev
4.2.1 ARMv6-M Compiler
The "GNU Embedded Toolchain for ARM" is suitable for compiling the Cortex-M0 power management firmware.
It can be downloaded from https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads .
For this manual, it is assumed that version 6-2017-q1 is used. Direct link to the file:
https://developer.arm.com/-/media/Files/downloads/gnu-rm/6_1-2017q1/gcc-arm-none-eabi-6-2017-q1-update-linux.
tar.bz2
Extract the tar.bz2 archive to /opt:
sudo tar -xf gcc-arm-none-eabi-6-2017-q1-update-linux.tar.bz2 -C /opt
