3.5. Introduction

The purpose of this User Guide is to provide detailed information regarding the usage of TI Sitara MCU MCAL configurator/generator package. The Microcontroller abstraction layer (MCAL) is the lowest layer of the AUTOSAR Basic Software architecture. The figure below shows MCAL layer in the AUTOSAR BSW software stack.

_images/Block_Autosar.png

Figure 1: AUTOSAR architecture.

Each MCAL driver has a driver implementation portion and a configurator/generator portion. The configurator/generator portion is described in this user guide.

MCAL generator/configurator steps in the standard AUTOSAR ECU configuration flow is circled below.

_images/Ecu_configurator.png

Figure 2: Ecu_configurator.

The TI MCAL configurator/generator package uses Elektrobit Tresos for the MCAL configuration and code generation.

This TI MCAL module’s ECU parameter definition is captured in Elektrobit xdm format.

This TI MCAL modules are delivered in the form of EB tresos plugins.

This configuration of the MCAL modules can be done using the Elektrobit Tresos Configuration Editor.

Once the configuration is complete, code generation for precompile, link time config and postbuild configuration is done using the EB tresos code generation feature.

This TI MCAL delivery is on AM263 platform.

3.5.1. Supported Devices/Platforms

This release supports AM263 series of SoC.

3.8. Working with Command Line

  1. To start the command line

    • Open the Windows command prompt.

    • Change into the directory, into which you have installed EB tresos Studio; e.g. C:/EB/tresos.

    • Change into the bin subdirectory.

    • You can execute a command by using tresos_cmd.bat; e.g., type tresos_cmd.bat –help to see a short help for the command line options.

Commands for legacy code generation

EB tresos Studio supports legacy mode. This mode worksindependently from projects. Use Recommended setting xdmfiles as input present in config_input/”Module”_TI_AM263x/config_ext/.

Command to generate code is as follows. E.g

“C:/EB/tresos/bin/tresos_cmd_64.bat” -Decuid=AM263 -Dtarget=ARM - Dderivate=AM263 legacy generate -n Can -g Can_TI_AM263x -o “output directory to store output” config_input/ Can_TI_AM263x /config_ext/Can_Rec.xdm

Options description:

-Decuid - This option specifiesthe Idof the imported ECU.

-Dtarget - Defines the target architecture

-Dderivate - Defines the target’s derivate

-n - Specifies the name of the module configurations of the configuration files to load

-g – Module Id -o - Sets the directory to which the generated files are written.
