C64x RESET

Started by ksatyakrishnan September 17, 2003
Hi,

Currently I am working on the DSP (C64x) booting in our system. In
the c6000 periphral guide(SPRU190d), in HOST boot mode description
it was mentioned that.

"HOST boot : The CPU is held in reset while the remainder of the
device is released. During this period, an external host can
initialize the CPU's memory space as necessary through the host
interface, including internal configuration registers, such as those
that control the EMIF or other peripherals."

From the above exlanation my understanding is

" During the CPU RESET, HOST can configure the DSP's EMIF interface
and HOST can access the DSP's external SDRAM through the configured
EMIF interface. "

Could you please correct me if my understanding is not correct.

Regads,
Satya

yes - that is a correct understanding... the HOST can
access the whole memory space of the DSP...

good luck...
