[FAQ] EVMK2GX: Build Linux for K2G - ARM

Pre-requisite:

1. Linux-PC with Ubuntu 18.04 LTS
2. Download and Install " PROCESSOR-SDK-LINUX-K2G — Linux Processor SDK for K2G " from https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-K2G (Make sure SDK is installed in "$HOME" directory)

Steps:

1. Install all the dependency packages (Open Linux bash terminal and give the following commands).

   sudo apt-get install diffstat texi2html texinfo subversion chrpath build-essential subversion ccache sed wget cvs coreutils unzip texinfo docbook-utils gawk help2man file g++ bison flex htmldoc chrpath libxext-dev xserver-xorg-dev doxygen socat u-boot-tools git

2. Download the arm compiler toolchain using the below commands and extract them in "$HOME" directory

   wget https://developer.arm.com/-/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz
   tar -Jxvf gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz -C $HOME
   wget https://developer.arm.com/-/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz
   tar -Jxvf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C $HOME
   cd ~/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin

3. Export Toolchain: Add the toolchain path to the "$PATH" variable
    

   vi ~/.bashrc
   export PATH=$HOME/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin:$PATH
   export PATH=$HOME/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin:$PATH

4. Building Linux: Goto "{SDK_FOLDER}/board-support/linux-{VERSION}/" folder and give below command

   make clean distclean ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
   ls arch/arm/configs/ | grep k2g
   make tisdk_k2g-evm_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
   make -j8 zImage dtbs ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
   ls -al ./arch/arm/boot/dts/keystone-k2g-evm.dtb
   ls -al ./arch/arm/boot/zImage

5. After successful compilation, inside "k2g_evm" directory "zImage" and "keystone-k2g-evm.dtb" file will be present.

Screenshots are attached for the above commands -
