MCUSW
|
SoC's such as AM62X/AM62A/AM62P/AM62D/AM275 integrate an MicroController Unit Subsystem (MCU SS) as an chip-in-chip. It operates using a separate voltage supply, clock sources and resets and includes the components needed for device management. This allows the MCUSS to function continuously regardless of the state of the rest of the device. MCU SS has one or more DUAL core Cortex R5F (number of instances varies on the variant of the device, please refer the device reference manual)
MCAL is expected to run on Main domain R5F0_0 core for AM275X and Mcu domain R5F0_0 core for AM62DX/AM62AX.
MCUSW consists of two main components, Microcontroller abstraction layer (MCAL) & Demonstration applications (MCUSS Demos). Its is expected to be hosted on Cortex R5F 0 in MCU Domain or other Cortex R5F in main domain. The table below lists SoC/Cores on which MCUSW can be hosted.

In case of Sitara MPU/SPMCU, MCUSW is released seperatly and is not part of SDK.
EB Tresos is an AUTOSAR-compliant tool used for configuring and generating basic software modules.
A valid license is required to access and use EB Tresos. For EB License and other EB-related information, please check: Access to EB Tresos Tool and License.
Demonstrates usage of various drivers / software provided for MCU SS. These applications could employ FREERTOS as OS and use MCAL and/or PDK drivers.
Please note, these demos are currently not supported on Sitara MPU/SPMCU Family of Devices.
MCAL is the lowest layer of the AUTOSAR Basic Software architecture. MCAL contains drivers with direct access to the μC internal peripherals. MCAL is a hardware specific layer that ensures a standard interface to the Basic Software.
This user guide details procedure that are common to all MCAL drivers, please refer driver specific user guide for finer details of driver.

Dependencies can be categorized as listed below. Please note that depending on the intended use, the dependencies vary (e.g. for integration vs running demo applications only)
Please refer to the Sitara MPU/SPMCU Device SDK Getting Started Page. (For example, for am275x visit https://www.ti.com/tool/download/AM275-FREERTOS-SDK, under documentation there will be SDK Getting Started Page).
Sitara MPU/SPMCU Device EVMs includes an on-board XDS110 USB emulator, which could be used with CCS. Please refer to ti.com or contact your FAE for documents describing the EVM.
An external emulator such as Spectrum Digital XDS560V2 could be used, all steps remain identical to steps listed in (Built in emulator) with creation of Target Configuration being the exception.
While creating the target, please select the emulator that is being used.
Please refer MCU+SDK Documentation Getting Started Page to begin with SDK installation. Please refer to release notes for updated information on supported Compilers.
Get required MCU Plus SDK release version from below locations, and place it in same location as mcusw folder.
This is required for building and validating MCAL Applications.
Elektrobit Tresos (EB) is used to configure the MCAL modules, please refer EB Tresos Information for details.
This tool would be required to re configure the MCAL modules provided by TI.
Code Composer Studio is an integrated development environment (IDE) that supports TI's Microcontroller and Embedded Processors portfolio.
Please refer to Release Notes to find the supported CCS Version. Please refer to SDK User Guides for CCS Setup instructions.
In MCU+SDK user-guide inside Getting Started there will be a section called CCS Launch, Load and Run this will have CCS Theia related information, on how to use, setup, build and run applications via CCS-Theia ({SDK_user_guide} >> Getting Started >> CCS Launch, Load and Run).
