Linking nios_soft.elf fails:region onchip_memory is full

Hi

In my design, I want the NIOS II code to be run from SDRAM

and I want to use the onchip memory for data

I created the design in SOPC, disconnected the onchip memory from the instruction master under nios II processor ..

yet, whenever i build my project in NIOS II IDE i keep getting this message (i understand it is trying to load the program on onchip still and that it doesn't fit ) .. what is going wrong?

how can i instruct the system to use sdram as nios instruction memory .. and onchip as data memory?
