Hello Sir/Madam,

   Recently I do the research on i.MX8 family (8X and 8) for automotive application (digital cluster and infotainment).

   I want to know the design purpose of ARM cortex-M4 core from your side, for real-time application or power consumption purpose?

 

   Is it possible to run separate OS in A core and M core? e.g. AUTOSAR in M core and POSIX OS in A core. In this case, how about the power domain separation? I'm thinking this scenario that A core and GPU are shutdown, only M core and some peripherals e.g. CAN controller working in a very low energy mode to save power consumption, could you give me some advice on that?
