Azure Sphere 20.03 update is now available in the Retail feed. This update includes enhancements and bug fixes in the Azure Sphere OS; it does not include an updated SDK.


The 20.03 release incorporates the following changes and bug fixes:

  • Updated the Linux kernel to 4.9.213 LTS
  • Fixed a bug where PWM settings were not updated after PWM output was disabled; the period and duty cycle were changed, and then output was re-enabled
  • Fixed a bug where the network interface status was incorrectly reported as "Connected" after the network was disabled by a call to **Networking_SetInterfaceState**
  • Fixed SPI bugs that could result in kernel crashes
  • Fixed an issue that could cause the device to run out of memory after repeatedly deleting an application
  • Fixed a problem that could cause an OS update to loop


For those who have a valid Azure Sphere OEM Customer License Agreement (CLA), 20.03 is a required update and use is subject to the terms and conditions of such agreement. For more information on getting the updated Azure Sphere OS, see Azure Sphere OS feeds.
