The Azure Sphere OS quality update 20.08 is now available for evaluation via the Retail Eval feed. The retail evaluation period provides 14 days for backwards compatibility testing. During this time, please verify that your applications and devices operate properly with this release before it's deployed broadly via the Retail feed. The Retail feed will continue to deliver OS version 20.07 until we publish 20.08.
The 20.08 release includes enhancements and bug fixes in the Azure Sphere OS; it does not include an updated SDK.
The following changes and bug fixes are included:
We have also released new guidance to device manufacturers that should improve the stability of device-to-PC connections, e.g. in a manufacturing setting. In particular, we have updated the FTDI EEPROM configuration file in the azure-sphere-hardware-designs repo on GitHub to use 'D2XX Direct' mode instead of Virtual Com Port (VCP) mode. This new file also enables auto-generation of a random serial number, which will enable more reliable and flexible device identification in future releases of the SDK.
