How to flash Nios II program (C code) permanently?

Hi,

1.Generation of memory initialization file and combining elf executable into hardware project sof.

and convert sof to pof based on configuration scheme

I want my program stick permanently into my NIOS processor

What non-volatile memory are you intending to use to store your program? The Nios core itself won't (necessarily) store anything.

Is this a development board or your own design?

Hi Alex,

Thank for your reply. I used my own design development board. Is it possible if i use OnChip Memory on IP Catalog? Or please give me advise for the best solution. I have plan to deploy my NIOS design to end user. So the customer only program the C code without to know anything about my processor design. i am beginner about this, really expect for you advice. Thank you

best regards

Hi Anand,

I have find the clue of your solution. I combine the elf file (converted to hex file) and sof file and then the chip worked successfully. But, i have a further question. Is it possible if we put the hex file to separate non-volatile memory? so i can freely change my C code without combining my sof file and the elf file? thank you

best regards

What device family are you using? MAX 10?

The 'generic nios ii booting methods user guide (https://www.altera.com/en_us/pdfs/literature/ug/niosii_generic_booting_methods.pdf)' covers all you need to know. Depending on your FPGA family you'll be booting from UFM (MAX 10) or OCRAM.

Also have a read through the 'nios ii processor booting from on-chip memory (ocram) (https://www.altera.com/documentation/iga1446487888057.html#nio1505517080158)' section of the 'Embedded Design Handbook'. This takes you through more specific design examples.

Cheers,

Alex
