[HELP] External Flash: Nios program + Permanent data

Hello im a beginner in FPGA stuff, 

 

After dwelling with sdcard, i gave up on the sdcard and now i am back to the flash chip on my de2-70 board to store permanent data.... 

 

Currently, i can store my program externally in that flash using flash programmer but now i want to modify the program to store permanent data in the flash for future usage.... 

 

My question is where should i change in my project plus in the software.... 

 

also when i tried to program using hal.... the program stuck at the line where the write operation takes place.... 

 

Hence i suspect that the offset im using is not right.... how can i know which offset to use when writing to flash.... 

 

Cut short... 

 

i have my program which is flashed to cfi flash device... then i want to write my data below this program memoty address..hence i think i need the safe offset to write my data.... 

 

how can i do this? 

 

ps: sorry if this is a repost since i really dont understand the jargons used before this...
