NIOS II Booting methods for MAX10 FPGA

Hi, Mahalakshmi

Option 4 allows you to execute your application on external flash and data on external RAM.

And Option 5 allows you to copy your application and data from external flash to external RAM, and then run both from the external RAM.

Thanks.

Hi Eric,

Thanks for your reply,

It is not a QSPI, we need to boot from external parallel flash, Can we still use option 4 or 5?

Please confirm.

Thanks,

Mahalakshmi

Hi, Mahalakshi

Yes, you can boot MAX10 from external parallel flash using Intel CFI IP in your Nios design.

Do you still have any questions ?

Thanks.

Hi Eric,

we are using Quartus 15.0, and TRI STATE CONTROLLER IP to interface external parallel flash.

I did not find CFI IP in Quartus 15.0

Can we proceed with TRI STATE CONTROLLER IP itself and boot nios from this external parallel flash?

Thanks,

Mahalakshmi

Hi, Mahalakshmi

You can boot Nios II with MAX10 FPGA from an external parallel flash.

You may try 19.2 or later.

You may refer to below for the implementation:

By the way, can we close it if you have no more inquiry ?
