DE2 Booting from CFI

Hello everyone,

I have a DE2 Cyclone 2 kit. Now, I want to update program from the nand flash and run it on RAM. After a feel day, I consulted from altera documents and read threads on Altera forum. I have some questions:

1. I found that the Nios II create the .flash file. Is this file written to nand flash and also included the boot copier in it?
2. If I change the application code and write manually this file using alt_write_flash to the specific address (offset 0x00), will the new application be booted?

If someone have done this problem, please help me,

Thanks and best regards!
