Device OS (Firmware) for Particle Devices

v6.0.0

4 weeks ago

Device OS 6.0.0 Release is available in the Web IDE, Particle CLI and Workbench for (Argon/Boron/B SoM/B5 SoM/Tracker/Tracker M/E SoM X/M SoM/P2).

Released on January 30, 2024

Note: This is a limited Release and may be used for production with approval from Particle.

Gen 3 256KB application binary support

Device OS v3.1.x and further releases bring support for 256KB application binaries to all Gen 3 platforms (at that time: Argon, Boron, B SoM, B5 SoM, Tracker). A few important aspects of this change:

  1. Compatibility with 128KB applications built with < Device OS 3.1 versions is maintained. Devices can still run them even if other parts have been upgraded to Device OS 3.1+.
  2. Upgrade process OTA (including product-based upgrades) is transparent.
  3. When upgrading locally (using DFU or Serial), make sure to update the bootloader first, as it has some logic managing compatibility between 128KB and 256KB application types. See this page on steps how to perform the update.
  4. If using standalone Particle CLI installation, make sure it's updated to >= 2.12.0 version, which includes support for 256KB applications.
