Honored ContributorAre you sure you can't use the NIOS? It's really pretty darn simple to get ethernet running with it. Are you saying you don't have space in the FPGA for the NIOS or you don't have enough RAM space for the NIOS code?
I use the NIOS running the InterNiche TCP/IP stack without an OS. Here are some things to consider... 1 - You're going to have to define some kind of packet protocol to carry your information. You're going to have to do this regardless of whether you use a soft TCP/IP stack or a hard TCP/IP stack. The only difference is it's going to be much harder if you do it in gateware vs. C code. 2 - If you've already gotten the simple socket server running, then you've already overcome 95% of the work involved in getting a TCP/IP stack running in your FPGA. How far along are you in implementing a TCP/IP stack in firmware? The only reason to move the TCP/IP stack into gateware in my opinion is speed. It doesn't sound to me like you need the speed for what you are doing so why go through the pain. BTW. The place to change the static IP address in the simple socket server is found in the "simple_socket_server.h" header file. Look for the following: --- Quote Start --- # define IPADDR0 192 # define IPADDR1 168 # define IPADDR2 1 # define IPADDR3 234 --- Quote End ---
