Is there a way to combine sof and elf files ?

Actually my requirement is to combine the .elf with the .sof

And now i have made my .hex(NIOS exe) as a memory initialization file to a onchip rom..and set the reset address of nios to this memory

I followed the instructions given above , but could not succed

There wasn't any error, the onchip-memory(rom) was not getting initialized.

I solved the problem now.I had set that particular module which has the onchip-memory(rom) as DESIGN PARTITION then.so it was not compiling the newly added changes.

Now it is working obsolutely fine after i deselected the SET AS DESIGN PARTITION option for that module and the nios is executing from the onchip -ROM

Hi

I am trying to do the same thing by following the instructions of this post.

However, in my case, only the sof file works and the elf file is not working.

I'm wondering if I miss anything and hope someone could kindly help me.

I have a simple project which controls two leds.

After the sof file is downloaded, the second led is on.

If the elf file is working on the NiosII CPU, the first led blinks.

I cannot see the led blink after I download sof file which initializes the on-chip memory with the hex file converted from elf.

Here are some detailed steps:

1. The reset vector of NiosII CPU is already set in the on-chip memory.

(Please see my attached qsys file)

2. The "Enable non-default initialization file" option is checked. The initialization file is "my_nios2_mem" which locates in the root of my project.

3. The "my_nios2_mem.hex" is generated from elf file with the following command:

bash-3.1$ elf2hex --input=sof_elf_epcs_niosii.elf --output=my_nios2_mem.hex --base=0x00000000 --end=0x0003ffff --width=32

Hi Daixiwen

Thanks for your reply.

If the hex file cannot be found, there will be a critical warning as you remember.

I had this critical warning in the beginning and I have solved it already.

So I believe Quartus II can find the hex file.
