6713 Flash/SDRAM

Started by s0s0c September 22, 2004
Hello,

I am very new to DSP and the C6713, but I seem to be picking it up
pretty fast. I have a question regarding the connection of SDRAM
and a Flash chip to the C6713. The Spectrum Digital DSK board uses
an Altera PLD as the glue logic. I am designing a board that uses
similar RAM and Flash and I want to eliminate that chip. All of the
external peripherals do not need to go through
the CPLD to operate, so I would like to implement some type of
hardware design that will be able to use the flash to boot up and
the sdram for buffer space when the program is running.

I have bussed all the address and data lines and have run the clock
to the RAM. But I am unsure how to connect the /AWE/SDWE
and /AOE/SDRAS pins as each pin needs to go to both chips.

Can I just bus those lines and use the chip select?

Thanks for any help,
Mark

Yep, that's all there is to it.

Make sure you get the flash on the right CS if you want to boot from it
:-)
