Retrieving Software Version Information

Overview

OpenECU provides methods for retrieving software version information. This version information can be retrieved over CCP using your calibration tool, or it can be retrieved using a standard J1939 or UDS message. Additionally, any version information can be used by your application software.

How do I retrieve the platform software version that is running on my ECU?

There are two blocks that allow you to retrieve the platform version:

  • psc_PlatformBuildDate: Outputs the day, month, and year that the platform software was built.

  • psc_PlatformVersion: Outputs the major, minor, and sub-minor version numbers for the platform software.

To find these blocks in the Simulink Library Browser, navigate to:

OpenECU -> Versioning -> Target Versioning

Refer to the subsequent sections for methods on how to implement these blocks in your model.

To retrieve the software version from the target, simply add the newly created signals as display variables in your calibration tool.

How do I retrieve the bootloader software version that is running on my ECU?

There are two blocks for retrieving the bootloader version:

  • psc_BootBuildDate: Outputs the day, month, and year the bootloader software was built.

  • psc_BootVersion: Outputs the major, minor, and sub-minor version numbers for the bootloader software.

To find these blocks in the Simulink Library Browser, navigate to:

OpenECU -> Versioning -> Target Versioning

How do I retrieve the reprogramming software version that is running on my ECU?

There are two blocks for retrieving the reprogramming software version:

  • psc_PrgBuildDate: Outputs the day, month, and year the reprogramming software was built.

  • psc_PrgVersion: Outputs the major, minor, and sub-minor version numbers for the reprogramming software.

To find these blocks in the Simulink Library Browser, navigate to:

OpenECU -> Versioning -> Target Versioning

How do I retrieve the software version of my application that is running on my ECU?

There are two blocks for retrieving the application software version:

  • psc_AppBuildDate: Outputs the day, month, and year your application software was built.

  • psc_AppVersion: Outputs the major, minor, and sub-minor version numbers for your application software.

To find these blocks in the Simulink Library Browser, navigate to:

OpenECU -> Versioning -> Target Versioning

How do I create a version number for my application?

Every OpenECU model must include a put_Identification block. Double-clicking the block opens a dialog where you can specify the version numbers for your application.

Example:

  • Major version number: 1

  • Minor version number: 2

  • Sub-minor version number: 3

After setting these, click OK and rebuild your model. Your application software will now contain a version number.
