Yocto provides a cross toolchain including the native tools and required ARM libraries. The cross toolchain is only available for 64bit Linux host PCs. Download the toolchain by saving the following link:
In order to install the toolchain, use the following commands to run the installation script:
chmod a+x poky-*.sh
sudo ./poky-*.sh
In order to use the toolchain, the environment for it must be sourced to the current terminal before it can be used to build applications: To build an application first source the environment for the toolchain:
source /opt/poky/3.0.2/environment-setup-cortexa9t2hf-neon-poky-linux-gnueabi
# This command sets up paths for the shell along with a number of other
# environment variable. For example:
$ echo $CC
arm-poky-linux-gnueabi-gcc -march=armv7-a -marm -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9 --sysroot=/opt/poky/2.2.2/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi
# Cross compiling a simple hello world program:
$CC hello.c -o hello
It is also possible to develop applications directly on the device via serial console or ssh. Yocto includes development tools such as vim, gcc, g++, gdb, make, autoconf, binutils, etc. See the next sections for using the cross toolchain with IDEs.
