S32K3xx OTA BootLoader

[Alicetian]

Hello:

I learned that the S32K3xx has OTA capabilities，When the OTA feature is enabled,Supports A/B swap and OTA Roll back.

Traditional firmware updates are via BootLoader，As shown in the following figure.

If I want to use the S32K3xx OTA function,Do I still need a separate BootLoader? Or integrate BootLoader flashing into App Firmware.

If a separate BootLoader is required,How the BootLoader memory region is divided.

Looking forward to your reply,Thanks!

Hi @Alicetian 

There is an OTA demo for S32K3 that you can find at S32K3 Reference Software -> Automotive SW - S32K3 Reference Software,

If you are not able to access it, please get in touch with your NXP representative for access.

Also, take a look at Automotive Security and Over-the-Air (OTA) solution with S32K3 MCU.
