SRAM vs SDRAM

Hi, I am about to design a system with uClinux, and I was wondering if the performances would be correct if I only used an SDRAM. SRAM is a bit expensive if I want to have enough memory to run...

> Do you still have an idea whether the SRAM is used or not ?

I don't believe it's used in the kernel version I'm using. It might

be mapped in mtd ... I never checked ... and I didn't see it mapped

into a region in the startup either.

No, the SRAM is not necessary -- you can run linux just fine without

it.
