Ethernet without using the Nios II

[mac23]

Is there an ethernet example that does not go through the Nios II processor and send and receives packets from a host computer? My assumption is that if Nios II is used then this means a C program has to be created to access registers, which I am trying to avoid. I am hoping to create the ethernet communication all through Verilog. Could I find some resources or help with this?

Hi mac23,

Thanks for submitting the issue. Allow me have some time look into the issue and I will get back to you with findings.

Hi mac23,

You may find the ethernet example design from the web page below https://www.rocketboards.org/foswiki/Main/WebHome

It seems that the projects listed in the rocketboards.org only support Linux project. Sadly, I am not able to access Linux.

Thank you for the help! Please do let me know if you could find other projects that aren't in accessed through Linux environment.

Hi mac23,

You also can find the design in the FPGA design store. For more projects, please do refer link below https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/design-store.html?q=window&s=Relevancy

Could you please refer me to an ethernet design that doesn't use the Nios 2 in the FPGA design store?

Thank you for your help!

Hi,
as far as I'm aware of, there's no support from Intel for hardware TCPIP stack. Neither rocketboard is a suitable source because it's dedicated to FPGA with harware processor system (HPS).

You can find a few hint in this recent same topic thread Re: Hardware TCP/IP stack - Intel Community

Hi mac23,

You can use TSE MAC ethernet IP without using the NIOS II soft core. AN647 TSE IP example design also did not use Nios II.

AN647 Application note and its example designs are available at below:

Hi mac23,

I wish to follow up.

Do you still have any question about this case?

Thanks for mentioning AN647. Related to the original intention to create ethernet communication all in HDL, it shows at least a direction. But as previously guessed, there's apparently no hardware TCP or UDP stack example.

Hi,

Since no hear any feedback from you, I am now close the case. If you have any question after the case closed, please do feel free to submit another issue.
