Co-processor?

[Jeremy97469]

I am fairly new to the Pine ecosystem and hope this is a good place to ask my question. Dose the PinePhone have a secondary processor that handles the real-time processing needs of a phone? I am seeing that the PinePhone has trouble receiving calls sometimes; is this a possible solution?

There is a small management core in the CPU itself that handles real-time stuff as well as power management. See https://linux-sunxi.org/AR100 for more information about the core. Many distros use crust (https://github.com/crust-firmware/crust) as the firmware on the core.
