Hi all,I am trying to integrate UDPIP IPCORE of CAST Inc with TSE MAC on StratixIII Dev Board in GMII interface but not succeeded. The board Led status are as follows. Link speed led- D8 is glowing Duplex led - D9 is glowing. RX led(D15) is blinking but TX led(D14) is not blinking. when i probe the signal coming from phy on signal tap nothing is coming(even rx_clk). I am connecting enet_gtx_clk(125Mhz) from FPGA to Phy and Tx_clk(125Mhz) from FPGA to PHY. When i swith 10/100 link ,ethernet link speed led switching accordingly so i think phy is behaving. but in GMII interface nothing is coming. please help me,i tried SR also but not resolved. with regards J S Hyanki
I do, but it's under NDA. Maybe Altera could help here?Anyway, do at least 16 bits timeout timer on reset signal and reset phy after power up. Keep reset active for a few miliseconds.
Hi socrates,As i gone through the TSE MAC document i did't find the how TSE MAC will initiate the MDI interface. I think by accessing the TSE MAC configuration, MDI interface works automatically or i have to make seprate logic for it. with regards J S Hyanki
--- Quote Start --- Hi socrates, there is RESET pin of PHY and MDI pin of PHY. so i think i should reset through reset pin only. with regards J s Hyanki --- Quote End --- Exactly. The reset through MDIO will be done in software later.
