I've read address 0x90080006, but the value is 0.
I halted the CCS and I change the value to 0x00000003, then I run the CCS again.
But I don't know whether it works or not, How do I know if it works or not ?

Regards,
Artiko Wibowo.

That

That

add
0x90080006.

Perform
a
byte
read
of
address
0x90080006,
or
the
value
that
you
read
with
3,
and
write
it
back.
The
three
will
enable
the
McBSP
ports
to
go
to
the
daughtercard.
Performing
the
read
will
keep

modifying
the

[I
don't

what
the

do
and
this
is

to
do
it.

The
6713
DSK
was
designed
and
manufactured
by
a
company
named
Spectrum
Digital.
They
created
the
CCS
drivers
that
connect
to
the
DSK
via
USB
and
usually
have
the
latest
versions
of
the
drivers
on
their
web
site.
