Description

• Article: Install the SDK

Definition of Done

• Documentation
• Should be able to run the SDK via the source command

Potential paths:

• Yocto
  • Custom Linux image from scratch, or
  • Leveraging OpenSTLinux
• Buildroot

Perhaps consider using a build server.

Research into how to get data collected by the microcontroller into the microprocessor so that it is accessible by Linux/Qt.

This does not require building/modifying the Linux Kernel nor getting its source code. Only the SDK is required for cross-compiling.

Description

• Follow the article, Populate the target and boot the image
• This tutorial leads to a demo launcher made with GTK.

Subtasks

• Download dependencies & install stm32CubeProgrammer
• Upload the Linux image to the SD card

Definition of Done

• Documentation
• Bootup to OpenSTLinux

• Choose a license
• Open Source Licenses and Embedded Linux
• GNU's info about licenses
  • License compatibility table

Qt

• QT Open Source License FAQ
  • Qt is mainly distributed under the LGPL, version 3 and GPLv2/v3. (LGPLv3 seems to be more encouraged)
• Based on the features page filtered with licenses, most of the modules and tools are supported through GPLv3
  • Qt Creator is not available under LGPLv3
  • Notably, CMake is available under BSD Clause 3
• Obligrationso f the GPL and LGPL — GPLv3 seems to be more suitable for our use-case

OpenST-Linux

• meta-st-openstlinux: MIT license
• OpenST-Linux can use Qt Creator

Yocto builds can take a long time to make, and have high storage requirements. Perhaps a Cloudshell instance from AWS may make more sense than an EC2 instance.

May want to check GitHub pro perks for remote linux perks

• Article: Develop on Arm Cortex M4
• These three article pages will lead to a demo program that uses OpenAMP for synchronizing/messaging with the Cortex A7.
• The Demo program runs a TTY for connecting to a serial console.

Subtasks

• Install CubeIDE
• Download the CubeMP1 package
• Run demo program

Definition of Done

• Documentation
• Running program with a functional TTY

• Developer Package
• Qt MP1 Quick Start Guide
• Build and Use an SDK for Qt

Research for how to do this is needed. It would be neat to have a DFR related splash-screen as it loads the dashboard app.

• Does this have something to do with the device's bootloader?
• What tools to create the animation?

Emulating a Raspberry Pi on QEMU with Docker

Description

• Build our own custom linux image.
• This will be a huge effort, as we need to decide between using Yocto or Buildroot, as well as discover how ST provides their layers and recipes.
• Digikey playlist: Intro to Embedded Linux
  • Covers both Yocto and Buildroot.
  • Happens to use the same dev board.
• Using Qt5 should be fine for our first attempt. We may consider integrating Qt6 later.

w/ Yocto:

• Wiki: OpenEmbedded

w/ Buildroot:

• Blog: Updated buildroot support for stm31MP1 platforms

Definition of Done

• Documentation
• A functionally running board with our own linux image

The sample app is made with Qt6. We may be able to run this on the target device if the project were to use Qt5 instead, as it is provided by the custom Linux image detailed on ST's wiki pages.

The steps for this process are in our Wiki:

• Build the custom image
• Build a custom SDK based on that image
• Use that image to cross-compile your Qt5 app
• Transfer the resulting executable/binaries to the target device, and run it

The libraries for communicating to the ECU and leveraging the CAN bus is already implemented. This is currently held in the DAQ repo.

Research how to implement our firmware into the microcontroller of the stm32mp1 device to parse ECU messages.
