Software Block Diagram

The main software components in the block diagram are described below

Software Components	Documentation Page	Description
OS Kernel
No RTOS	NO RTOS	Contains modules which implement no-RTOS execution environment consisting of timers, ISR, main thread. Allows software on top to run in bare metal mode.
FreeRTOS Kernel	FreeRTOS	FreeRTOS Kernel, provides a execution environment consisting of tasks, semaphores, timers, see https://www.freertos.org/RTOS.html
FreeRTOS POSIX	FreeRTOS	Limited POSIX APIs with FreeRTOS underneath, provides pthreads, mqueue, semaphore, see https://www.freertos.org/FreeRTOS-Plus/FreeRTOS_Plus_POSIX/index.html
Driver Porting Layer (DPL)	Driver Porting Layer (DPL)	APIs used by drivers to abstract the OS environment. Example, Semaphore, HW interrupts, mutex, clock.
Device Drivers and HAL (Hardware Abstraction Layer)
SOC Peripheral Drivers	SOC Peripheral Drivers	Device Drivers library and APIs for peripherals within the SOC. Example, I2C, GPIO, UART.
Safety Checkers Library
Safety Checkers	Safety Checkers Library	Safety Checkers Libaray
Examples
Examples	Examples and Demos	Examples showing usage of different SW libraries and APIs
Tools (used on host machine)
Code Composer Studio (CCS)	Using SDK with CCS Projects	IDE used to build projects, debug programs.
TI CLANG Compiler Toolchain	TI CLANG CGT Homepage	CLANG based ARM compiler from TI for ARM R5F and MCU-R5F
SysConfig	Using SDK with SysConfig	System configuration tool, used to configure peripherals, pinmux, clocks and generate system initialization code
TI Resource Explorer (TIREX)	Using SDK with TI Resource Explorer	Web broswer based tool to explore the SDK, select, import and run the examples

Directory Structure

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

makefile	Top level makefile to build the whole SDK using "make"
imports.mak	Top level makefile to list paths to dependent tools
docs/	Offline browseable HTML documentation
examples/	Example applications for AM62PX, across multiple boards, CPUs, NO-RTOS, RTOS
source/	Device drivers, middleware libraries and APIs
tools/	Tools and utilities like CCS loading scripts, initialization scripts.
${SDK_INSTALL_PATH}/source/

drivers/	Soc peripheral device drivers
kernel/	NO RTOS and RTOS kernel and Driver Porting layer (DPL) for these environments.
${SDK_INSTALL_PATH}/examples/
drivers/	SOC and board level focused device drivers examples. The examples are based on both NO-RTOS and RTOS

kernel/	NO RTOS and RTOS kernel focused examples
${SDK_INSTALL_PATH}/tools/
/	Additional tools and utilities used by the SDK

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

Folder/Files	Description
C:/ti/ccs1270	Code Composer Studio
C:/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
C:/ti/ti-cgt-armllvm_3.2.2.LTS	TI ARM CLANG compiler tool chain
C:/ti/gcc-arm-9.2-2019.12	GCC AARCH64 compiler
