Hi all

 

 

I want to know how to set the PLL_CTRL and CCGR register in i.MX7D.
I'm confuzing the setting because I can't understand the definition of Domain.

Q1.
There are a word "domain" in decription of SETTINGS field in CCM_PLL_CTRLn.
Does the word "domain" mean the CPU core number ?


Q2.
Which Core corresponds to each of Domains 0 to 3 is set by RDC_MDAn ?

Q3.
When I want to assaign A7 Core 0 and 1 to Domain0 and M4 assign to Domain1, do I set RDC_MDA0 to 0 and RDC_MDA1 to 1 ?

Q4.
I would like to do some processing independently from M4 from A7.
Do I assaign M4 to domain 1 when I use M4 only during A7 is Run or Wait?
