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:
