Upgrade sdram chip to 16MB for DE2 dev...

[Altera_Forum]

Hi hippo 

 My sdram memory is 8MB that not enough free memory to run some app program on uClinux,and i want to replace it .Recently ,I already find IS42S16800B sdram chip(16MB) that match all pins of IS42S16400 for DE2 board. I can know the pin 36 don't connect to FPGA chip from sdram PCB schematic . So, i only select 16MB for sdram chip, but I have not to buy it yet .  This is diference between the IS42S16400 chip and the IS42S16800B chip,as following:  IS42S16400 sdram chip(1Mx16x4bnaks): ==>8MB 1.Row addr input :A0~A11 (12 bit) 2.Column addr input: A0~A7 (8 bit)  IS42S16800B sdram chip(2Mx16x4banks): ==>16MB 1.Row addr input :A0~A11 (12 bit) 2.Column addr input: A0~A8 (9 bit)  Do you think that i can directly replace it ? or give me some advices .  Thx !

Yes, you can replace it. 

You need to update your sdram component in sopc builder.  Use the new uClinux-dist-test approach can save around 1-2MB , compared to old buildroot guide.
