Based on my understanding, you are requesting for reference design for Generic Serial Flash IP. You may refer to https://fpgacloud.intel.com/devstore/platform/18.0.0/Standard/generic-serial-flash-interface-intel-f... and migrate it to Arria 10 device.
Thank we are able print in nios II BTS, but in remote upgradation : sending .rpd file in the uart terminal is not happening. Can you give me some solution for how to flash the epcql1024 with uart terminal(without using Quartus tool I want flash the arria 10 device).
below i attached my project can give me solution.
May I know what is the issue that you are facing based on the UART interface? Have you tried SignalTap the internal signal to check if what is happening?
