Welcome to MCU+ SDK for AM62X. This SDK contains examples, libraries and tools to develop RTOS and no-RTOS based applications for ARM M4F CPU and related peripherals. Please note that MCU+SDK for AM62X only supports M4F MCU. This package should be used along with PROCESSOR-SDK-LINUX-AM62X 08.03.00.

Block Diagram

Given below is a block diagram of the SW modules in this SDK,

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
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. Currenlty only IPC_RPMessage between A53 and M4 is supported. More drivers will be added in the future.
Examples and Demos
Examples and Demos	Examples and Demos	Examples and demos 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, see https://software-dl.ti.com/ccs/esd/documents/users_guide/index_project-management.html
TI CLANG Compiler Toolchain	TI CLANG CGT HOMEPAGE	CLANG based ARM compiler from TI for ARM R5F and M4F
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.

source/	Device drivers, middleware libraries and APIs
${SDK_INSTALL_PATH}/source/
board/	Board peripheral device drivers. Currently no board peripheral drivers are supported. More drivers will be added in the future.
drivers/	Soc peripheral device drivers. Currently only IPC_RPMessage supported. More drivers will be added in the future.
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

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/ccs1120	Code Composer Studio
C:/ti/sysconfig_1.12.0	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_1.3.1.LTS	TI ARM CLANG compiler tool chain
