Getting Started
|
|
|

1. Install dependencies.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ sudo apt install build-essential libncurses5-dev gcc-arm-linux-gnueabi

|
|
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
|
|
|

|
|
|
|
|
|
|
|
- Python 3 venv in `env`
|
|
|
|
|
- r3build command in the env

|
|
1. Install uuu.
|
2020-09-28 00:49:26 +09:00
|
|
|
|
|
|
|
|
- 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.
