Uboot s32g2 run M7 and A53 core

[NP1]

I am currently working with an s32g2 board 

1. Can we able to run M7 core and A53 core separately ? How do we select /boot the respective core ? 

2. I have seen many places it specify about uboot . But I clearly didn't understood what is uboot and why it is required . Is there any document which I can refer to understand it's internal process? 

3. Is there any example project which shows IPC communication between M7 core and A53 core ? How do they communicate ?

Hello,

A1. Yes they can run separately

A2. you must read the internal documentation:

https://www.nxp.com/app-autopackagemgr/software-package-manager:AUTO-SW-PACKAGE-MANAGER

A3. they use rpsmsg

??? Maybe you are wrong? S32G2 use IPCF not rpmsg to A53 communicate with M7.
