Earlier this month, the Zephyr Project announced the release of Zephyr RTOS 2.2. A long list of enhancements and bug fixes contained in the release can be found in the release notes.

Major enhancements include:

  • Initial support for the 64-bit ARMv8-A architecture.
  • CANopen protocol support through 3rd party CANopenNode stack.
  • LoRa support was added through integration of the Semtech LoRaWAN endpoint stack and addition of a new SX1276 LoRa modem driver.
  • A new and redesigned GPIO API. All in-tree users have been ported to it.
  • Added support for numerous new boards and shields.

This release is the result of the hard work and skill of many individuals engaged with the project over the last three months, with a total of 2642 commits from 205 different contributors. We would like to thank all those who engaged with the project to help make Zephyr 2.2 a success!

The full list of new supported hardware can be found in the release notes, however the following are some of the newly added boards and shields:

What’s next

Zephyr development never stops and has continued actively also after the release. There are many interesting things lined up for Zephyr 2.3 and 2.4 such as Bluetooth Advertising Extensions, LLVM support for all architectures and improved toolchain abstraction. More details can be found in the release plan.
