Hi, MFM

I only modify the file EP1C20.h in include/configs/ directory to fit my Cyclone Board (the FPGA chip is EP1C6),

Then type the following commands

make EP1C20_config

make

then produce the u-boot elf image

and in nios sdk shell I download the system.sof then

nios2-download -g u-boot and it download to the address 0x1FC0000

my sdram address is begin at 0x0 (8M)

my flash addess is begin at 0x800000 (2M)

how to modify the address in which the u-boot image download to ?

warm regards.
