Hi uilka_b (http://www.alteraforum.com/forum/member.php?u=10640)!

Thank you very much for you reply!!!

In my project, the reset vector is define to a flash , and I can programe the flash through the nios flash programing. But I have to add CFI table for the SST flash. Can I say my flash was correctly used?

I have seen some people say that if the reset vector is to one flash, this flash can not be open in nios by alt_flash_open_dev. Is that true?

By the way, I can use the same code to open and control my epcs all correctly,(because I have not use the epcs as the boot loader flash?)

Can you give me some advice about how to open my boot loader flash? Because the epcs flash is to slow to erase and write.

Thanks again!
