.elf file

Altera_Forum · ‎03-21-2006

We have received an .elf files from our suplliers and try to run it here on our board. We're encountring difficulty running this file. we don't seem to be able to download this file in the SDRAM in the correct format which enable us to run it properly. Please let us know if there are certain steps that need to be taken to be able to start running off of a .elf file.

Thanks,

Koorosh

Hi koorosh,

All you should have to do is open a shell window and execute:

$ nios2-download -g file.elf

You might also want to make sure the sections are mapped to meaningful

memory regions. You can use objdump for this:

$ nios2-elf-objdump -h file.elf

If everything looks good, but you're still having problems, you might want

to use nios2-console -- this will let you load, peek, poke, whatever.
