increase sdram size on nios dev kit

Hi nios experts,

I have an altera niosII 2s60 dev kit and those came with 16Mbytes of sdram (1 chip). Has anyone tried to swap this with a larger sdram chip? Anyone see a problem with just dropping in a larger chip, will there be any problem associated with the sdram controller?

please advise,

-Quan

    If you get a chip which is completely pin-compatible, then all you need to do is change the parameters in the SDRAM peripheral in your SOPC Builder system to match the new chip. Caveat engineer, though; if it doesn't work, you're on your own.

    Just an update.

    I installed a pin-4-pin compatible part for the sdram (MT48LC8M32B2TG) and all is good. I now have 32 MBytes of ram to play with instead of the default 16MBytes.. Had to do as Mike suggested, changing the sdram setting inside sopc builder and rebuilding the entire project.

    Process was relatively easy overall.
