Nios V on External Memory

[JLee25]

Hi all,

   I am looking for support on Nios V executing on external memory.

This is a customer board with C10 GX.

The EMIF has been verified using the EMIF toolkit and the calibration report is fine.

I followed the steps to have the Nios V booting from GSFI, execute from onchip_ram and it's fine.

Now I change the settings of Linker Section Mapping to EMIF,

Then it's not working anymore.

Nios Vm connects to EMIF through an Avalon MM clock crossing bridge.

And the Quartus version is Pro. 24.1.0

Any suggestions or comments?

Thank you.

Hi

For booting from EMIF. It is a little bit different from OnChip Memory.

In the OnChip memory you will initialize the OnChip Memory with the application hex and the NiosV processor do not need to transfer the application from another location.

For booting in the EMIF you could use the steps listed here:

https://www.intel.com/content/www/us/en/docs/programmable/726952/22-1-21-2-0/processor-application-copied-from-boot.html

You just need to follow the instruction replacing the RAM with your EMIF.
