Honored ContributorUpgrade sdram chip to 16MB for DE2 dev...
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 !22 Replies

Execute nios2-linux-uclibc-gcc 123.c -o 123 -elt2flt 2. cp 123 to ~/uClinux-dist-test/romfs/bin 3.make linux image But i can't run my app program under uClinux. How to compile my apps program under uClinux-dist-test that is correctlly ? Thx ! - Altera_Forum--- Quote Start --- originally posted by jay_1025@Jun 5 2006, 08:10 PM hi hippo

I think that I miss 2 steps with "make" and "make romfs". 1. Execute nios2-linux-uclibc-gcc 123.c -o 123 -elt2flt 2. cp 123 to ~/uClinux-dist-test/romfs/bin 3.make 4.make romfs 5.make linux image I can run my app program under linux and have some problems. But this app program can run under linux-2.6.16.1 that is ok .
