Using MCUXpressoIDE how to generate OTA file

[vishnubeema]

Hello,

Using MCUXpressoIDE I am able to generate .bin and S reconrds.

Right click on .afx file -> Binary Utilities -> Create Binary.

But I am trying to understand on how to generate OTA file used for Over-The-Air upgrade.

Thanks & Regards

Hello Vishnu Beema,

It depends on which IDE you are compiling your code. On IAR, you need to define linker symbols to prepare the image to be OTA ready and with MCUXpresso, the linker file needs to be modified. Depending on the wireless stack, you can refer to the documentation for configuring an example as an OTA client. For example, for Thread, you can refer to Chapter 3 Software implementation of the Kinetis Thread Stack Over-the-Air (OTA) Firmware Update User's Guide.

A quick way to get started is to run an OTA client example application which will already have the appropriate setting for building the OTA binary.

Let me know if you have any question.

Best regards,

Gerardo
