Flash generated using sof2flash fails to configure fpga

Altera_Forum · ‎09-06-2010

Hi ,

I have Stratix IV development kit ,

I want to load Flash file converted using sof2flash utility.

when i use nios2-flash-programmer it works fine .

but it fails to configure FPGA from flash when i cycle power the board .

Anybody have idea ?

I don't know which EDS version you're using but there's at least a bug in version 9.1. Check these threads:

I've had the same problem and was able to get it working with EDS 9.1 SP2.

I skipped SP1.

Good luck, Ton

Thanks , but i am currently working with EDS 9.1 SP2 . Is there any PFL or optionbit issue ?

Altera_Forum · ‎09-06-2010

I used sof2flash with the following options:

sof2flash --input=stratix_iv.sof --output=stratix_iv.flash --offset=0xC20000 --pfl --optionbit=0x18000 --programmingmode=FPP

Success, Ton

Thanks Ton,

i successfully flashed .sof using that , actually i was using programmingmode=PS .

But you are flashing the sof using factory default CFI flash map.

when i tried to boot from software flash(elf2flash) it goes to Kernel Panic.

sof2flash -------- as u shown

nios2-flash-programmer --base=0x08000000 <yourfile>_hw.flash

Up to this it works fine , now i am converting linux image,

elf2flash --base=0x0a000000 --end=0x0bffffff --reset=0x0a820000

--input=<yourfile>_sw.elf --output=<yourfile>_sw.flash

--boot=path/boot_loader_cfi.srec

nios2-flash-programmer --base=0x0a000000 <yourfile>_sw.flash

now , i powercycle the board , it boots but comes kernel panic.

And if i want to load my custom sof and linux image without the factory default settings , is it possible ?

I can not understand ..why this happen ?

Hi Dipen,

Although I also used the Stratix IV development kit, I didn't use NIOS on it. My last NIOS experience is from some years ago, so I'm afraid I can't help you with the kernel panic problem. Well, at least you've set one step. Maybe for the next one, it's better to make a thread in a NIOS forum. I will follow it with interest.

Good luck, Ton

Thanks Ton . Its better idea to make thread on NIOS forum .
