Subject: the Usage of ROM and RAM of Cortex-M3 on OMAP4
Date: Tue, 21 May 2013 18:04:24 +0800	[thread overview]
Message-ID: <CAGsJ_4x+TC04ajK5DYV8CSvRk6xvnmATuj35ruetWjMgLAYcbQ@mail.gmail.com> (raw)

Hi All,
typically on OMAP4, Cortex-A9 will load the Cortex-M3 firmware and let
M3 run from the firmware. for example, on Android, Linux kernel will
use remoteproc module to load ducati-m3-core0.xem3 of Ducati.
but after reading the datasheet of OMAP4, there are internal 16KB ROM
and 64KB RAM for Cortex-M3. And the ROM is bootable. I'd like to know
who is using the embedded ROM and RAM and how they use. and can the
Cortex-M3 boot from ROM directly by itself?

Thanks
barry
