MCUSW
Getting Started

MCUSW

SoC's such as J722S 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)

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.

Core Naming Conventions

SoC Family Cores Names Referred as Comments
J722S MCU R5F Core 1 mcu 0 0 Please refer the "mcusw_release_notes.html" to determine if this release supports this platform. Note that all computing cores might not be supported in MCUSW

Getting access to MCAL

In case of J722S, MCUSW is released seperatly.

  1. Configurator is not included as a part of the package, it would require steps below to receive the configurator
  2. Configurator and Compliance Support Package (CSP)
    1. Configurator package is required to update/modify MCAL configurations
    2. Separate Installer for EB Configurator. This package includes plugins for j722S.
    3. Users can request access to the Configurator package and Compliance Support Package (CSP) from here My Secure SW Access Request on TI.COM
    4. Once access is granted, users can download the package from here My Secure SW on TI.COM
  3. Refer (Installation Steps) for detailed installation steps

License for Configurator

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.

Package Contents

MCU Demos

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 j722S Family of Devices.


MCAL

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

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)

  1. Hardware Dependencies (Hardware Dependencies)
  2. Software Dependencies (Software Dependencies)

Hardware Dependencies

Please refer to the j722S Device SDK User Guides for Hardware Boot Mode details.

Built in emulator

J722S 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.

Emulator

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.


Software Dependencies

For J722S Family of Devices:

Please refer to release notes for updated information on supported Compilers.

MCU+SDK

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.

  1. TI Website for J722S

MCAL Configurator : Elektrobit Tresos

Elektrobit Tresos (EB) is used to configure the MCAL modules, please refer (MCUSW) for details.

This tool would be required to re configure the MCAL modules provided by TI.

IDE (CCS)

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).
