Hi ! I'm trying to understand how to implement power management in our custom OS (bare metal, no Linux) on i.MX boards (6, 6sx, 6ul, 7, ..)
My first goal would be to be able to put a core to sleep, or event to power it off completely. And then, to implement a mechanism to wake it up again (using a timer interrupt or a key press / uart interrupt maybe ?)
Is there some documentation (besides the board reference manual) which explains this kind of things, to help me understand the process (CCM/GPC/SRC configurations, ...) ?
