EMIF configuration in DSP BIOS

Started by Meenakshi Matai ●October 6, 2005
Hello,

I am trying to use an already existing DSP BIOS project built for C67xx
and migrate it to be usable in C64xx. In the C67xx project there is
SDRAM configuration present under the EMIF settings. In case of C64xx
there is EMIFA and EMIFB. I want to be able to delete the SDRAM
configuration from under EMIF settings and add new configurations under
EMIFA and EMIFB for C64xx. Unfortunately, this is "greyed" out in CCS
v2.2 and I can not delete it. I can definitely add new ones, but not
delete the existing ones. It has a dependency with the EMIF Resource
Manager, but that is greyed out too.
I tried to build this project in CCS v3.1 and then I am able to delete
it and make changes as I want. The project builds successfully.

My question is how do I do something like this in CCS v2.2? How can I
make changes to the EMIF configurations if they are already existing and
are greyed out.

Thanks,
Meenakshi.

Did you change your processor type to c64x??

Yes, I did change the processor type to C64xx, both in the BIOS system
settings and in project build options.
