Hello all,
I have been trying to learn how to use the NIOS II flash programmer recently. Essentially, what I want to be able to do is power up my board and have the FPGA properly configured and my C code running on the processor, right off the bat. I have a DE2 board with a Cyclone II FPGA, and I am using Quartus II version 9.1 and NIOS II IDE version 9.1. Here's the issue:
If I use JTAG programming in Quartus to download the FPGA configuration to the board, the flash programmer in NIOS II IDE works just fine; I can download my code to the flash and run it. This would seem to indicate that there is nothing wrong with my system.
If I use AS programming in Quartus instead, permanently storing the FPGA config. on the board, then when I try to use the flash programmer, I get the "There are no Nios II processors available which match the values specified" error. It doesn't matter whether I set up the system library to put the FPGA configuration data and the program data in the flash, or program data only; I get the same error.
Does anyone know how I can fix this and get my board and program to boot up properly when I push the power button?
