Hello there, I've just migrated from Xilinx to Altera. Using the NIOS IDE I've created a system with working SW. I would like to program the on-board EPCS flash so on power up the FPGA is pro...

Honored Contributor --- Quote Start --- The question in point is how to program a NIOS2 software image into the EPCS flash. The easiest and fastest way to do this is with the NIOS2 flash programmer. Because of the way NIOS boots from EPCS flash, the flash programmer must program both the FPGA image and software image at the same time. Actually, we use the nios2-flash-programmer in field/manufacturing environments all the time because of it's speed advantage over the JIC method. The nios2-flash-programmer can be run from the command line for advanced users just as the quartus programmer can.

I have ensured the jtag-module-reset output from the NiosII processor connected to the epcs flash controller reset input. can you give some help? Thank you very much! Sincerely Luke.
