|
||
|
||
## 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:
|
||
```
|

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:
|
||
```
