Software Architecture

Oct 20, 2021

Use this space to document use cases during the Oct 2021 workshop.

 

  • Pick a time frame – Model Year 27. (i.e., 5 year time frame)

  • Ready for teams to start product development in spring or summer of 2024.

  • What the use cases we are enabling?

  • What does AGL provide?

  • What does OEM and Tier One need to integrate?

 

  • Can we use flatpak to deploy Flutter apps?

  • Gap between Toyota Flutter implementation and Base system that has been released to AGL in Application management areas. May be released by Toyota in the future.

  • App developers don’t want to know anything about Yocto. They want to be able to write and deploy their apps.

  • Open Source (Supply chain?) Cyber security built in

  • Yocto LTS and AGL LTS – Yamaguchi-san: We should think about using Debian rather than Yocto for security updates over a very long term.

  • ISO 21434: Cyber Security in automotive will be required

  • IC will not use Flutter – do we need to maintain a non-Flutter version

  • What is most important to the ecosystem, AGL components or the a complete distribution with demo/ reference apps?

    • Tier Ones have their own internal Linux system. How does AGL convince a Tier One to an AGL component or to the AGL distribution as a whole?

  • APIs

 

Use Cases:

1) As a developer I want to write an app and simply deploy it to AGL using QEMU. 

  1. Develop app on my local desktop, test using cloud based CI/CD, then deploy to real hardware for testing seamlessly. 

2) As an OEM I want interaction between the IC and IVI displays running both displays from a single SOC. 

3) As an OEM or Tier 1 I want an open choice of app development toolkits such as Qt, Flutter, React, etc. 

4) As a driver I would like to be able to update the IVI system for the lifetime of the car (at least 5 years) without out any significant downgrade of performance. This includes=

  • Security patches

  • New features using existing hardware

  • OTA update so I do not have to return to the shop for everything.
