thanks ,and i found it's short of a header file called "sys/alt_flash_dev()".firstly i think we should initialize the device, in my nios program, there's an initializing sentence (javascript:showjdsw('jd_t','j_'))-"alt_sys_init()", if i did not include the header file-sys/alt_flash_dev(), there is a warning. and the device(epcs & ext_flash) can not be opend. i don't know why.
