Error accessing memory address

"...I make my own hardware image ..."

does the board work with a predefined hardware and software

sample from altera ? could you debug, program such a sample ?

I only know the cyclone board, but I think it should be the same,

to check if your problem is perhaps the sdram, try to run

- your program from sram,

- a small testprogram fron onchip ram

check the settings of your cpu in sopc builder.

- reset address: flash

- exception address: onchip memory (in my case)

in system library set program and date memory to

sram or onchipmemory.
