Hi SwRa,

I think it is possible. but I have a question.

As the UI data is large, integrating the UI data into the image will make the image size larger than the MCU internal flash. For the OTA process, the current process is that store the image in the temporary area of the internal flash. Is there any example of OTA over QSPI Flash? I mean that OTA routine stores the image to QSPI first, and then moves the image(not including the UI data) to the internal flash.

Hi Jason,

Sorry for confusing you with my previous answer..

Since you need to update both the firmware as well as the UI data, the easiest way is to integrate the UI data into the image i.e., hardcode the data as static in the device firmware.. Could you check if it is possible to do this..?

Hi SwRa,

I was already able to update the FW via DFU OTA, but I have no idea on update the UI data because the UI data is not part of the FW, and it is stored in the external QSPI Flash.

Could you explain more details on "DFU followed by storing data"?

Hi Jason,

you could perform DFU followed by storing data. You could also take a look at this documentation for DFU : Add DFU support to your application
