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:
```
