hi all:
My nios2 board use 16m sdram. but I check the free memory with command "free",I find the total memory = 8796. # free total used free shared buffers Mem: 8796 3072 5724 0 8 Why the user memory so small? How can I increase the user memory if I do not increase the SDRM capability? Can I modify kenerl source code or "menuconfig kernel" to increase the user meomory? Thank a lot!Link Copied

check the datasheet of your sdram maybe that is 16MBit.- Mark as New

Are you using busybox for shell and services? They will take up a lot of memory when the busybox gets bigger..
You may try the later uClinux-dist approach with SASH and standalone services.
