I tried using the method in the link, by copying the boot_loader_cfi.srec file to my Nios II software directory and running alt-file-convert.exe through the Nios command line. This is the error I received. It seems suspiciously similar to the old error. Unfortunately, the output of the executable is ambiguous as to which file it could not find, the .ELF or the bootloader, although I suspect that it is the bootloader. I tried omitting the --boot option from the executable arguments, and got a different error - "must be str, not NoneType".

If I can't convert my .ELF file to a hex, I'm kind of dead in the water with my design. Can someone else please weigh in on this?

Hi Devin,

I tried the link and generate the hex file successfully.

But for unknown reason, my Nios 2 does not boot after programming.

I noticed minor difference between your setting and mine.

Anyway, i attached my command below for your reference,

FYI!

BRs,
