Secure firmware upgrade support - RT1172 MCUs

[Hariprasath_K]

Hi,

We are studying the i.MX RT1172 processor to see if this will be suitable for our product.

We have a product requirement to perform secure firmware upgrade with rollback support OTA via Wi-Fi on the end customer site.

I have gone through the secure boot documentations. But I couldn't find any reference to secure firmware upgrade support by i.MX RT 1170 processors. Does secure bootloader of this processor supports secure firmware upgrade with rollback mechanism? If not any recommended solution to be implemented by the application is available?

Note:
- We have decided to use MQX RTOS. This is to allow porting our existing product code to the newer version.
