Can IPC mode load a separate application on the second MCU core if that R5f processor is operating in split mode?

Hi Dayo,

IPC-mode is a term used at the Linux kernel level. The remoteproc driver deems a remote processor to be in IPC-only if it is booted before the Linux kernel is up, either by U-Boot or by some other remote processor.

The Linux SDK currently operates MCU R5F in LockStep mode, and there is missing support to boot the MCU R5F Core1. It needs to be shutdown first in R5 SPL, before a new application can be loaded and booted by either U-Boot or Linux kernel.

Suman
