DRA80XMEVM: what is the meaning of domain in the boot flow ?

There are two types of domains, MCU domain and Main domain.

I'm confused about why TI distinguishes between these two domains.

    Hi,

    As you may know, there are two big domains - MCU and Main, each with own processors and peripherals. Main reason to differentiate boot between MCU-only and Main domain boot is that first and second stage boot can be accomplished even if only MCU domain is active (powered). I.e.  Main domain may become unpowered for some reason.

    You can refer to TRM chapter 4. Initialization for more details regarding MCU-only boot.

    Regards,
