Meadow v2.* Releases

Updating Instructions​

v2.0.0.3​

Meadow.OS v2.0 - the reliability release, is here, and while only an incremental upgrade from v1.15, it’s the culmination of nearly two years of work of stability fixes and polishing to make Meadow an ultra-reliable, full-featured, IoT OS that you can rely on for your critical applications. In setting out goals for Meadow.OS v2.0, we defined our reliability metrics as having three critical components:

  • Stability - The OS should run reliably for months at a time without a failure that would require a reset to remain operationally viable. As such, we defined any OS failures that cause a reset as aberrative priority-0 issues.
  • Recoverability - If the OS or user application takes down the OS or freezes it, the system should reliably restart and recover without manual intervention.
  • Reportability - On app or OS failure, the failure will be logged and sent to Meadow.Cloud or available locally for review.

Along the way, any issues that were found that didn’t meet these requirements were marked as priority-0 issues and Meadow.OS v2.0 represents the final clearing of all of them!

We’re super excited about this major milestone for Meadow.OS and extremely thankful for all of our customers with real-world applications in the field that worked with us to identify, diagnose, and fix these issues to make this the most reliable Meadow.OS yet.

In addition to being a hugely important milepost in the development of Meadow, the following changes and improvements are also to be found in this release:

Meadow.OS​

As part of the 2.0 effort, the OS and the entire Meadow platform has gone through more extensive and exhaustive planning and testing than any of our previous releases, and has been running our test devices and harnesses with perfect uptime for our model applications. As part of this release, several minor issues were resolved in OS and App OTA, as well as in USB debugging initialization.

Finally, the bootloader no longer ‘flicks’ any F7 LED pins as indicator of an update in progress as those pins are user I/O in some Meadow form factors.

  • Added IDigitalSignalAnalyzer interface.
  • Added Changed event to IRheostat interface.
  • Bug fix - external storage insert and removal events.
  • Bug fix - internal resistors in Meadow.Linux.
  • Bug fix - ethernet adapter link status when the cable/link is already plugged in.
  • Bug fix - health monitoring cases where some OS failures and .NET exceptions were not being reported.
