QEMU/AArch64 VIRT BSP Introduction

中文页 | English

1. Introduction

The AArch64 execution state was introduced with the ARMv8 ISA for machines executing A64 instructions. This project ported RT-Thread on QEMU AArch64 VIRT machine.

2. Compiling

Usage ARM Developer GNU ToolChain, it support Linux and Windows:

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads/

Download the xxx-aarch64-none-elf of x86_64 hosted platform，set the RTT_EXEC_PATH is system environment after decompress the binary.

Enter directory rt-thread/bsp/qemu-virt64-aarch64 and input:

scons

3. Execution

The project execution tool is qemu-system-aarch64, the project can be configured to Cortex-A53/A57/A72, GIC supports V2/V3 version, and V2 of GIC can use 8 processors max.

Download Windows platform from website:

https://www.qemu.org/download/

On Linux platform (Ubuntu, Deepin and so on), install QEMU by apt.

sudo apt update
sudo apt install qemu-system-arm

Please fixup the exec scripts if modify the default configuration of the project. Run qemu.bat or qemu.sh in terminal:

heap: [0x40042aa0 - 0x40142aa0]

Use VirtIO-Console in new terminal by:

telnet 127.0.0.1 4321

If use tap net mode with tap0 card, modify qemu run script config

-netdev user,id=net0

-netdev tap,id=net0,ifname=tap0
