# AArch64 emulation system
This repository setup a simplest Yocto build system to emulate a complete aarch64 Linux system (trusted-firmware-a, u-boot, kernel, initrd, rootfs). This might be helpful for those who want to:
- Understand all basic components in a Aarch64 Linux Embedded System and how they work together.
- Develop your own Linux distro, write BSP layer, and port components (kernel, u-boot, trusted-firmware-a) to your platform.
- Have hardware limitations or want to learn emulating with QEMU.
For more detail about the system, visit the [Main Blog](https://embeddedos.github.io/posts/simplest-emulation/).
## `meta-lava` layer
This layer contains minimal components to build an Aarch64 Linux distro run QEMU platform. This includes:
- 1 distro: `lava-distro`.
- 1 machine: `lava-machine`.
- And few recipes that build components from local sources.
The directory structure:

└── lava.wks
```
## Build system
To clone external repos (tfa, u-boot, kernel):
```bash
git submodule update --init
```
Build system:
```bash
kas checkout
kas build
```
And start emulating with `runqemu`:
```bash
source openembedded-core/oe-init-build-env
runqemu nographic
```
That's it 😛
