External MCU update reference solution
If your product incorporates an Azure Sphere chip and another MCU you can use Azure Sphere to deploy updates to the external MCU. This makes use of an Azure Sphere application's read-only resources which can include firmware images for external MCUs.
The External MCU Update nRF52 reference solution demonstrates how to use Azure Sphere to update firmware on a Nordic nRF52 over a UART interface.
