5.3.4.4.3. Booting From EPCS/EPCQ Flash, Running From On-Chip Memory

This method is very similar to the previous method. The difference is the boot images are stored in EPCS/EPCQ flash, not CFI flash. In this method, set the Nios® II reset address to the base address of a boot ROM implemented as FPGA on-chip memory. Load the boot copier executable into the boot ROM when the FPGA is configured, after the hardware design is compiled in the Intel® Quartus® Prime software. The boot copier begins executing when the Nios® II processor is reset, copies the application code from EPCS/EPCQ flash memory to RAM, and then branches to the application entry point.
