Introduction
Welcome to FreeRTOS SDK for AM62DX. This SDK contains examples, libraries and tools to develop RTOS and no-RTOS based applications for ARM R5F, ARM A53, TI C75 and related peripherals.

Block Diagram
Given below is a block diagram of the SW modules in this SDK,
The main software components in the block diagram are described below
Software Components |
Documentation Page |
Description |
|---|---|---|
OS Kernel | ||
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 Kernel, provides a execution environment consisting of tasks, semaphores, timers, see https://www.freertos.org/RTOS.html |
|
FreeRTOS POSIX |
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) |
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 |
Device Drivers library and APIs for peripherals within the SOC. Example, I2C, GPIO, UART. |
|
Board Peripheral Drivers |
Device Drivers library and APIs for peripherals on the board or EVM. Example, Flash. |
|
Software Diagnostics Library | ||
Safety Checkers Library | ||
Safety Checkers |
Safety Checkers Library |
|
Signal Processing | ||
Signal Processing |
Supports real-time signal processing operations for embedded and high-performance applications. |

|
Tools (used on host machine) | ||
Code Composer Studio (CCS) |
IDE used to build projects, debug programs. |
|
TI CLANG Compiler Toolchain |
CLANG based ARM compiler from TI for ARM R5F and MCU-R5F |
|
TI C7000 Compiler Toolchain |
CLANG based ARM compiler from TI for C75 |
|
SysConfig |
System configuration tool, used to configure peripherals, pinmux, clocks and generate system initialization code |
|
TI Resource Explorer (TIREX) |
Web browser based tool to explore the SDK, select, import and run the examples |
|
SDK Tools and Utilities |
Additional tools and utilities, like flashing tools, booting tools, CCS loading scripts used with the SDK development flow |
