STM32MP257F-EV1

Hello,

I tried to understand what does A35-TD does better than M33-TD flavor and vice versa. But I don't find enough information. The information that confuses me is it says A35-TD Flavor has Hard real time on Arm Cortex-M33. What does it mean operation wise- what capabilities does it have extra compared to M33-TD Flavor? Could someone please help me understand this?

Thanking.

with regards

Amit

Thanks Oliver,
That page only helped in initial understanding but lacks deeper insight into the differences. However, I found some information from other sources.

Thanks
