Hi everyone,I'm using a DE1-SoC board. I'd like to transfer data from FPGA to HPS and I have to use the avalon interface but I never used this interface. Anyone can have some document or example? My project consist in acquire data from the FPGA pins and then send data in a SDRAM that is shared with the HPS and finally send to the PC throught the ethernet interface. Anyone can help me? Thank you Gianluca
