NixOS


Buildroot

Elimo Engineering integrated support for the PineCube into Buildroot.

This has not been merged into upstream Buildroot yet, but you can find the repo on Elimo's GitHub account and build instructions in the board support directory readme. The most important thing that this provides is support for the S3's DDR3 in u-boot. Unfortunately mainline u-boot does not have that yet, but the u-boot patches from Daniel Fullmer's NixOS repo were easy enough to use on buildroot. This should get you a functional system that boots to a console on UART0. It's pretty fast too, getting there in 1.5 seconds from u-boot to login prompt.

How to compile

You can either setup a machine for the build environment, or use a Vagrant virtual machine provided by Elimo Engineering

On a dedicated machine

Recommended system requirements:

  • OS: (L)Ubuntu 16.04
  • CPU: 64-bit based
  • Memory: 8 GB or higher
  • Disk: 15 GB free hard disk space

Install required packages 

sudo apt-get install p7zip-full git make u-boot-tools libxml2-utils bison build-essential gcc-arm-linux-gnueabi g++-arm-linux-gnueabi zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32z1-dev

Install older Make 3.82 and Java JDK 6 

pushd /tmp
wget https://ftp.gnu.org/gnu/make/make-3.82.tar.gz
tar xfv make-3.82.tar.gz
cd make-3.82
./configure
make
sudo apt purge -y make
sudo ./make install
cd ..
# Please, download jdk-6u45-linux-x64.bin from https://www.oracle.com/java/technologies/javase-java-archive-javase6-downloads.html (requires free login)
chmod +x jdk-6u45-linux-x64.bin 
./jdk-6u45-linux-x64.bin 
sudo mkdir /opt/java/
sudo mv jdk1.6.0_45/ /opt/java/
sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.6.0_45/bin/javac 1
sudo update-alternatives --install /usr/bin/java java /opt/java/jdk1.6.0_45/bin/java 1
sudo update-alternatives --install /usr/bin/javaws javaws /opt/java/jdk1.6.0_45/bin/javaws 1
sudo update-alternatives --config javac
sudo update-alternatives --config java
sudo update-alternatives --config javaws
popd

Unpack SDK and then compile and pack the image 

7z x 'PineCube Stock BSP-SDK ver1.0.7z'
mv 'PineCube Stock BSP-SDK ver1.0' pinecube-sdk
cd pinecube-sdk/camdroid
source build/envsetup.sh
lunch
mklichee
make -j3
pack
Using Vagrant

You can avoid setting up your machine and just use Vagrant to spin up a development environment in a VM.

Just clone the Elimo Engineering repo and follow the instructions in the readme file

After spinning up the VM, you just need to run the build: 

cd pinecube-sdk/camdroid
source build/envsetup.sh
lunch
mklichee
make -j3
pack
