when EDMA transferring data between L2 and external memory, how to set the EMIF register?

Started by Unknown May 8, 2008
Hi everyone,
The dsp in my project is dm642. When i use DAT_copy transferring data
between SRAM on chip and 2 32bits SDRAM external(64bits sdram), the
data was wrong during transferring. I have found that if i set the
external memory as asynchronous through EMIF register it will get the
right data. But other part in the project will have some problem,
because the external memory is 64bit asynchronous. So the problem is
that how can i set my EMIF registers to ensure both of them are runing
right?
Or the problem was caused by other part of system but EMIF registers
setting?

Maybe you can try to post the message to http://www.dsprelated.com/groups/c6x/1.php

The user group there has more focused discussion about each specific
DSP chip.

That may be true, but why is that important? I would think the more important factor is the number of C6x users that attend the forum. In that respect it makes more sense to me to utilize comp.dsp because it is historically the place people have come for DSP information. Sites lsuch as dsprelated tend to dilute the information and attendants (in addition to other disadvantages due to the privately-owned nature of the site). In other words, having one central, public repository of DSP information and attendants (comp.dsp) makes more sense to me than diluting that information and those attendants across several sources such as sites like dsprelated. For one thing, it saves time having to search all those other sites. What happens tomorrow when Joe B, C, D, ..., want to run their own dsp sites in addition to Joe A's dsprelated site? This has already begun to happen to some extent re: ad's here recently for other such sites. -- % Randy Yates % "She has an IQ of 1001, she has a jumpsuit %% Fuquay-Varina, NC % on, and she's also a telephone." %%% 919-577-9882 % %%%% <yates@ieee.org> % 'Yours Truly, 2095', *Time*, ELO http://www.digitalsignallabs.com
