Hello. We are considering the adoption of Azure RTOS for IoT Device. Is there a page that guides us on how to update Azure RTOS to IoT Device using IoT Hub or IoT Central? What we want to know is how to update the Azure RTOS itself, not the IoT Device firmware update. Thanks in advance.

@HinataGrape-6694, to update the Azure RTOS portion on an IoT device is similar today to update the entire firmware which Azure RTOS now has already supports by using the Device Update for IoT Hub service: https://learn.microsoft.com/en-us/azure/iot-hub-device-update/ And you can try with some key boards we already have samples for: https://github.com/azure-rtos/samples/tree/PublicPreview/ADU And like @Scott Azure RTOS mentioned, we are yet to include the secure boot as part of the sample to ensure the security on the device end. Please let us know further questions you have on this.

Hello, we do not yet have a secure bootloader that will update Azure RTOS. This is something we are actively working on.

@Liya Du @Scott Azure RTOS
Thanks so much!

Let me check just to be sure.
Am I correct in assuming that the Azure RTOS itself can be updated in the same way as in the following tutorial?

https://learn.microsoft.com/en-us/azure/iot-hub-device-update/device-update-azure-real-time-operating-system

Also, am I correct in assuming that NetX Duo includes the Device Update Agent from the beginning (no need to install it additionally)?

Thanks in advance.

Yes, it's a complete firmware based update, so anything within the firmware incl the Azure RTOS as well as your own device application logic can be updated.

@Liya Du
Thank you so much!

I learned that the Azure RTOS can be executed using the same procedure as firmware updates.

It was helpful.
