Hi everyone , my aim is to implement a simple system who permits to send data to a PC only using the phisycal layer of the ethernet interface of the board de2/115. Following a tutorial I had built the sistem, but the related software for the nios II processor permits only a loop comunication between the ethernet interfaces of the board. Anyone can help me , for example suggesting a tutorial or posting a code who can works for this project ?Thank you
If you really want to implement a system at the PHY layer, you shouldnt be using a NIOS. You need to read this https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/xcvr_user_guide.pdfIt wont be simple. Have you read this for a TCP/IP stack? https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/tt/tt_nios2_tcpip.pdf
Thank you for your reply, I was reading your second link, there are some tutorial design, but they are not for my board, I`m using a cyclone IV.It is possible to migrate a design from cyclone III to cyclone IV ?
