Compiling Environment
1.1. Compiling Environment
Because Kamino18 is a heterogeneous architecture SOC, we need install both arm and mcu cross-compile toolchain to compile the whole source code.
1.1.1. Openwrt Compiling Environment Setup
The YodaOS working on Kamino18 platform is compiled based on openwrt SDK. Through openwrt, we can make rootfs image and get cross-compile toolchain. Before using openwrt sdk, please make sure the below tool packages have been installed in your Ubuntu PC.
- sudo apt-get install build-essential subversion libncurses5-dev zlib1g-dev gawk gcc-multilib flex git-core gettext libssl-dev unzip texinfo
- sudo apt-get install device-tree-compiler
- sudo apt-get install gcc-4.7-arm-linux-gnueabihf
- sudo apt-get install libusb-1.0-0-dev
1.1.2. Compiling Toolchain Environment Setup
The YodaOS source package also contain toolchains as below：
├── toolchains
│ ├── arm
│ ├── csky
│ └── scripts
The toolchains folder contain arm and csky(MCU) two cross-compile toolchains. In order to use these two toolchains, we need setup environment parameter as the below commands：
- source env.sh
- export ARCH=arm
- export CROSS_COMPILE=arm-openwrt-linux-gnueabi-
Note: These two toolchains need use on 64bit ubuntu-16.04 PC environment.
1.1.3. MCU Compiling Environment Setup
The VSP subsystem in Kamino18 consists of MCU and DSP two parts. MCU(CK) is the control part. DSP is the algorithm process part. The dependency environment of MCU cross-compile toolchain（toolchains/csky/）is as below：
- sudo dpkg --add-architecture i386
- sudo apt-get update
- sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libx11-6:i386 gtk2-engines:i386 lib32ncurses5 lib32z1 libxtst6:i386 libgtk2.0-0:i386 lib32ncurses5 libcanberra-gtk3-0:i386
