Simplifying Zephyr Usage Through Linux Host Integration Jason Kridner (EOSS 2023)

​

  • Linux nodes can be more expensive, but offer greater remote access and redundant connectivity options
    • Terminal shell, rotated journals, virtualization, and more…
    • Large storage, high-level database queries, …
    • Common execution environment as server infrastructure
  • Zephyr nodes are growing in capability, but data will touch Linux system eventually for storage, analysis and presentation

Greybus and Project Ara

  • Greybus comes from Project Ara
  • Project Ara sought to create a modular mobile phone, so you could update only what you want
  • Needed to make embedded busses hot pluggable
  • In mainline kernel, using Unipro

Replace GBridge in BeagleConnect

Ayush Singh for Google Summer of Code 2023

​

Problem: The existing architecture revolves around GBridge. Ran in userspace and interacted with gb-netlink in kernel. Design was brittle and could hang kernel.

Replace GBridge in BeagleConnect

Ayush Singh for Google Summer of Code 2023

​

Solution

  • Eliminate GBridge and merge its functionality into greybus (linux driver) and cc1352 driver.
  • Allow Greybus Linux driver to directly communicate with cc1352
  • Move SVC and APBridge roles into cc1352
