TI C7000 Compiler Toolchain	TI C7000 CGT HOMEPAGE	CLANG based ARM compiler from TI for C75
SysConfig	Using SDK with SysConfig	System configuration tool, used to configure peripherals, pinmux, clocks and generate system initialization code

Directory Structure

Given below is a overview of the directory structure to help you navigate the SDK and related tools.

Folder/Files	Description

Given below are the paths where the different tools needed outside the SDK, like CCS, SysConfig. In Linux, the tools are installed by default in ${HOME}/ti.

Folder/Files	Description
${HOME}/ti/ccs1250	Code Composer Studio
${HOME}/ti/sysconfig_1.20.0	SysConfig. NOTE, SysConfig is also installed as part of CCS at ${CCS_INSTALL_PATH}/ccs/utils/sysconfig_x.x.x
${HOME}/ti/ti-cgt-armllvm_3.2.1.LTS	TI ARM CLANG compiler tool chain
${HOME}/ti/ti-cgt-c7000_4.1.0.LTS	C7000 compiler tool chain
