WARNING : PHY[0.0] - Auto-Negotiation FAILED

[APaga1]

I have been trying to implement Nios II simple socket server from the reference design : https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/nios-ii-simple-socket-server-ethernet-example-for-cvgt/

I was able to setup everything and start downloading the Nios II software project to the board. But while doing so, I am facing this auto negotiation failed warning. i am unable to decide whether the connection to the board was established or not. I have disabled the DHCP and given the address 192.168.1.234 in the simple_socket_server.h file. I have been following the steps mentioned in the document  https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/tt/tt_nios2_tcpip.pdf

Previosly i have implemented CVGT Simple_Socket_Server from the document https://www.intel.com/content/dam/altera-www/global/en_US/uploads/9/97/CVGT_Simple_Socket_Server_Design_Example.pdf where I have used the static IP for TCP/IPv4 with the IP address 192.168.1.1 . It worked fine. Kindly help me with the Auto negotiation error. Even I wanted to do the timing analysis to see if there is any violation. But I'm unable to find the sdc file in the project. Kindly HELP!!

Hi Avinash,

Could you provide any possible screenshot of this while uploading the software into your fpga for better understanding? Besides, regarding the sdc file for timing I am still looking onto it internally cant guarantee but I will keep you updated.

Thanks,
