I am trying to implement NIOS II Simple Socket Server on Cyclone V GT device (https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/nios-ii-simple-socket-server-ethernet-... ). But when giving the run, I am facing the errors related to mismatch in the timestamp. There are two sopcinfo files for ethernet_standard_main_system in the downloaded project directory and only one sof file in the master_image. Which sof file should I choose to program the board and which sopc file should I use to create the project in NIOS SBT? I am attaching the related pics.
The .sopc for eth_std_main_system is the top level file. You only need to program one file, ie the .sof.
You may need to re-compile the reference design example and re-generate the programming file .sof again.
