This might be helpful for those who want to:\n\n- Understand all basic components in a Aarch64 Linux Embedded System and how they work together.\n- Develop your own Linux distro, write BSP layer, and port components (kernel, u-boot, trusted-firmware-a) to your platform.\n- Have hardware limitations or want to learn emulating with QEMU.\n\nFor more detail about the system, visit the [Main Blog](https://embeddedos.github.io/posts/simplest-emulation/).\n\n## `meta-lava` layer\n\nThis layer contains minimal components to build an Aarch64 Linux distro run QEMU platform. This includes:\n\n- 1 distro: `lava-distro`.\n- 1 machine: `lava-machine`.\n- And few recipes that build components from local sources.\n\nThe directory structure:\n\n```text\nmeta-lava/\n├── classes\n│   └── lava_src.bbclass\n├── conf\n│   ├── distro\n│   │   └── lava-distro.conf\n│   ├── layer.conf\n│   └── machine\n│       ├── include\n│       └── lava-machine.conf\n├── README.md\n├── recipes-bsp\n│   ├── tfa\n│   └── u-boot\n├── recipes-core\n│   └── images\n├── recipes-kernel\n│   └── linux\n└── wic\n    ├── lava-extlinux.cfg\n    └── lava.wks\n```\n\n## Build system\n\nTo clone external repos (tfa, u-boot, kernel):\n\n```bash\ngit submodule update --init\n```\n\nBuild system:\n\n```bash\nkas checkout\nkas build\n```\n\nAnd start emulating with `runqemu`:\n\n```bash\nsource openembedded-core/oe-init-build-env\nrunqemu nographic\n```\n\nThat's it 😛\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fembeddedos%2Farm64_emulation_system","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fembeddedos%2Farm64_emulation_system","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fembeddedos%2Farm64_emulation_system/lists"}
