buildbrain
This repository includes:
- linux-brain, u-boot-brain and nkbin_maker as submodules
- Useful build targets in Makefile
- r3build.toml to watch changes that occur in submodules
Confirmed environments
- Debian 10 (buster) amd64
Getting Started
-
Install dependencies.
$ sudo apt install build-essential bison flex libncurses5-dev gcc-arm-linux-gnueabi -
Clone this repository with recursive clone enabled.
$ git clone --recursive git@github.com:brain-hackers/buildbrain.git- If you've cloned it without
--recursive, run following command:
$ git submodule update --init --recursive - If you've cloned it without
-
Install uuu.
- Follow the instruction and build
uuuexecutable. - Put
uuuwhere the PATH executable points to.
- Follow the instruction and build
Build and inject U-Boot
-
Run
make udefconfig-sh*to generate.config.- For Sx1:
make udefconfig-sh1 - For Sx6:
make udefconfig-sh6
- For Sx1:
-
Run
make ubuildto build whole repository and generateu-boot.sb.- i.MX283 loads a packed U-Boot executable called
u-boot.sb.
- i.MX283 loads a packed U-Boot executable called
-
To inject the executable into i.MX283 in recovery mode, run
make uuu.
Build and make NK.bin
-
Run
make udefconfigto generate.config. -
Run
make ubuildto build whole repository and generateu-boot.bin. -
Run
make nkbin-maker. -
To make
nk.bin, runmake nk.bin.- nkbin_maker packs
u-boot.binintonk.bin.
- nkbin_maker packs
Build Linux
-
Run
make ldefconfigto generate.config. -
Run
make lbuildto generatezImage. -
Confirm that
linux-brain/arch/arm/boot/zImageexists.
Bootstrap Debian 10 (buster)
-
Run
make ldefconfig lbuild. -
Run APT cache in background (mandatory):
make aptcache. -
Run
make brainux. -
Run
make image.sd.img -
Confirm that
image/sd.imgis built and burn it to an SD card.
Watch changes in submodules & auto-build
-
Run
make setup-devto prepare a Python venv to watch code changes. Namely;- Python 3 venv in
env - r3build command in the env
- Python 3 venv in
-
Run
r3build. It'll detect the changes you make and builds the corresponding executable automatically.
What's r3build?
r3build is a smart file watcher that aims to provide hot-reloading feature like Web frontend development.
