-# buildbrain
+buildbrain
+==========
+
+This repository includes:
+
+ - linux-brain and u-boot-brain as submodules
+ - Useful build targets in Makefile
+ - r3build.toml to watch changes that occur in submodules
+
+
+Getting Started
+---------------
+
+1. Clone this repository with recursive clone enabled.
+
+    ```
+    $ git clone --recursive git@github.com:puhitaku/buildbrain.git
+    ```
+
+    - If you've cloned it without `--recursive`, run following command:
+
+    ```
+    $ git submodule update --init --recursive
+    ```
+
+2. Then run `make setup` to prepare an build environment. Namely;
+
+    - Python 3 venv in `env`
+    - r3build command in the env
+
+3. Install uuu.
+
+    - Follow [the instruction](https://github.com/NXPmicro/mfgtools#linux) and build `uuu` executable.
+    - Put `uuu` where the PATH executable points to.
+
+
+Build and inject U-Boot
+-----------------------
+
+1. Run `make udefconfig` to generate `.config`.
+
+2. Run `make ubuild` to build whole repository and generate `u-boot.sb`.
+
+    - i.MX283 loads a packed U-Boot executable called `u-boot.sb`.
+
+3. To inject the executable into i.MX283 in recovery mode, run `make uuu`.
+
+
+Build Linux
+-----------
+
+1. Run `make ldefconfig` to generate `.config`.
+
+1. Run `make lbuild` to generate `zImage`.
+
+1. Confirm that `linux-brain/arch/arm/boot/zImage` exists.
+
+
+Watch changes in submodules & auto-build
+----------------------------------------
+
+1. Run `r3build`. It'll detect the changes you make and builds the corresponding executable automatically.
+
+
+What's r3build?
+---------------
+
+[r3build](https://github.com/puhitaku/r3build) is a smart file watcher that aims to provide hot-reloading feature like Web frontend development.
