I am trying to run the Nios simple socket server reference design 16.0 in the Quartus version 16.0 (https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/nios-ii-simple-socket-server-ethernet-example-for-cvgt/) and followed the steps as mentioned in https://www.altera.com/en_US/pdfs/literature/tt/tt_nios2_tcpip.pdf . I am getting some software error(Screenshot uploaded).

 

16.0 errors without fixes.png

I have searched a solution in the Intel Forums where I came across https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd08112014_745.html .

I have made the changes as mentioned by replacing EXT_FLASH with ETH_STD_MAIN_SYSTEM_EXT_FLASH . (My qsys file name is eth_std_main_system.qsys) . But I got the errors as seen in the screenshot.16.0 errors after fixes.png

The above complete process is repeated for Quartus versions 15 and the errors persist.

Kindly help.
