CHAPTER

FOUR

SOFTWARE GUIDE

This chapter provides instructions for compiling and deploying the BSP (Board Support Package) software to the Q7 mod-

ule.

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 (Cortex-M and Cortex-A), two different compilers are

needed. The table below list the parts and their instruction set.

BSP Part

Instruction set

Cortex-M0 power management firmware

Cortex-M

ATF (ARM Trusted Firmware)

Cortex-A

U-Boot bootloader

Cortex-A

The Linux kernel

Cortex-A

Debian user-space

Cortex-A

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”
