nios2 on cyclonev gx, software boot at power up

[GOMEZ_IT]

Good morning everyone.I created a system based on NIOS2 and FPGA, on a terasic cyclonev gx (terasic) dev board. The NIOS2 software uses both on chip memory and external SDRAM.By first loading the FPGA configuration (via JTAG) and then the NIOS2 software (again via JTAG) everything works correctly.I can't understand what the correct procedure is to create a .pof file to write to the epcq256 that contains both the configuration and the NIOS software. Is the procedure the same as the one where the external SDRAM is not used as NIOS memory?

Regards, Luca

Hi,

Instead of .pof you use a .jic.

You can check the Embedded Design Handbook on the EPCQ booting method on XIP (Execute in place) from EPCQ programming:

https://www.intel.com/content/www/us/en/docs/programmable/683689/current/programming-96050.html

Once you have programmed, you can power cycle your board and it will load your hardware and software file from the .jic in the EPCQ flash.
