Hi,
We'd like to run Linux on core0 of P2020 and some bare metal application
running without OS
on core1. Is it possible to start this application from Linux ? I've
seen example of running 2 copies
of Linux in AMP mode, in which case both are started from u-boot. I'd
like to leave core1 in
reset, start Linux on core0 from u-boot and load bare metal application
from Linux. If this
possible, where can I learn about the procedure ?
Thanks.
Felix.

There is no of the shelf support for this. It would be reasonable easy =
to create a driver to load up your application for Linux and kick the =
second cpu to start it.
