2.6 Standalone Compilation

The following steps describe the standalone compilation process for u-boot source code and linux kernel
directly for RainboW-G17M-Q7 platform.

Refer Host package installation section to deploy the cross compiler and source code packages.

The cross compiler and sourced code packages are located in below path respectively.
<Path to G17M-BSP>/G17M-BSP/linaro/
<Path to G17M-BSP>/G17M-BSP/sources/

2.6.1 U-boot


Create a directory and open the directory in host to build the uboot
host@host~$mkdir <directory_name>; cd <directory_name>
Note: The u-boot source code tar file and patch file is located in the below path.
<Path to G17M-BSP>/G17M-BSP/sources/

Un-tar the uboot-iwg17m.tgz file in to newly created directory.
host@host/<directory>~$tar -xvzf <Path to G17M-BSP>/G17M-BSP/sources/uboot-
iwg17m.tgz

Change the directory to u-boot source code directory.
host@host/<directory>~$cd uboot-iwg17m

To apply the patch file, execute the below command.
host@host/<directory>/uboot-iwg17m
