In this episode, we learn how the BeagleBoard Foundation does open hardware and how their products can be useful in your product development efforts.

Notes:

• how Beagleboard products are different than Raspberry PIs
• why open hardware is important
• overview of some of Beagleboard.org’s products
• why upstreaming development is important
• how to do things right
• discussion about RISC-V
• and more

See the Beagleboard.org main site and documentation site for more information.

In this episode, we discuss our recent experiences building a product using Zephyr, and how Zephyr has helped us move fast and quickly integrate advanced features like a HTTP server, non-voltile store in flash, device support, etc. We also discuss how to set up a project in Zephyr and have built a project template that demostrates how to use the Zephyr T2 workspace setup. This template also includes common things projects need like a web application example.

In this episode, we discuss Yocto support for Nvidia embedded processors, such as the Jetson devices that are increasingly being used to power edge AI applications. Matt created and maintains the meta-tegra layer. meta-tegra is one of the highest quality BSPs we’ve used, so learn from Matt how he maintains it, what makes a good BSP, and many other thoughts from an experienced Yocto/Embedded Linux developer.

In this episode, we discuss aspects running AI on edge systems (both microcontrollers and embedded Linux). Chris has a lot of experience doing this and has used AI at the edge in multiple projects to solve real problems. This episode provides an overview of the technology and will help you understand the steps to implementing an AI model in your system.

Chris has published an open source project for implementing neural networks on embedded systems.

Great discussion with Eystein on updating systems, how Mender has evolved over the last ~10 years, and more:

• Eystein has a background in Math and cryptography
• Company started as CFEngine
• Things people tend to not think about with system update:
  • security
  • reliability (power loss, does it resume downloads when there are network issues, etc.)
  • future products – is the solution general
  • scheduling
  • updating multiple devices in the system
• Mendor milestones
  1. OSS release
  2. SaS service
  3. advanced environments, complex deployments, orchestration, etc
• OSS foundation
  • open-core model
  • product led growth
  • is working well
• Programming languages
  • Switching the Mender client from Go to C++ so the client is more portable.
• Platform vs Product
  • Product – narrow set of problems, pick what you need, less vendor lock-in
  • Platform – wide focus and tends toward locked in
• Interesting in the technology space
  • Bootloader standardization would help a lot
  • ARM System Ready looks interesting.
• Advice for young engineers

In this episode, we had a great discussion with Drew about:

• Drew’s career – many interesting companies
• Toradex
  • manufacturers SOMs (System-on-Module)
  • started out providing WinCE solutions
• Torizon
  • opinionated stack
  • fully integration solution
  • container runtime – allows developers to deploy applications without knowing much about Linux
  • customize OS without doing Yocto builds
• Visual Studio Code plugin
  • simplifies management of Docker images, containers, cross compilation, remote debugging, etc.
• Torizon device side software is OSS
• SW update system
  • many options: Mendor, RAUC, SWUpdate, OSTree
  • Toradex uses OSTree
    • OSTree is file based for delta updates, where RAUC and SWUpdate are block based.
    • single partition
    • Git-like store where changes can be rolled back, etc.
    • read-only rootfs
  • Uptane is provides protection against attackers
• Greenboot – used to verify system is functioning properly
• Toradex’s upstream first policy
• Challenges in developing with Embedded Linux
  • drinking from the OSS firehose
  • understanding all the components
  • realistic expectations about how long this stuff takes to develop
  • regulations
• The future
  • immutable distros

In this espisode, we discuss what Yocto Dynamic Layers are, how they can help you manage changes for multiple layers, and how this helps you build an Embeded Linux Platform that you can scale accross time and products.

Documentation

See how we use them in the Yoe Distribution for an example of how you might use dynamic layers.
