1. Which nios2 version do you use ?

Old version is very slow.

2. Boot from EPCS or CFI will not increase free memory, it is the same as nios2-download to sdram.

You may follow my latest uClinux-dist , it will increase free memory.

3. Please post your nios2_system.h , altera.c and boot message again.

You may look in /proc for the info of your mtdblock0.
