Honored ContributorAltera TSE support (EXPERIMENTAL) + GMII ??
Hi all,
I was wondering which interface we must use between the TSE MAC and the PHY when the following option is selected in "make menuconfig" : [*] altera tripple speed ethernet support (experimental)When I check the driver files (atse.c and atse.h), I can't find an interface choice like in the other TSE MAC SLS driver... So which interface must be used : gmii
rgmii
mii I must tell that I strongly hope that the GMII will be the good choice :D Thanks for your help guys !! Papy

phy = marvell 88e1119 Ok guys today I can successfully boot uClinux with the TSE MAC (Experimental) selected : --------------------------------------------------------------------- eth0: atse.c: v1.1, June 3, 2008 by Joseph (Camel) Chen <[email protected]> eth0: atse.c: modified version by Eintisy Chuang <[email protected]> eth0: Altera Tripple Speed, ether hw addr 00:07:ed:0d:09:19, Marvell 88E1119 PHY --------------------------------------------------------------------- and make an ifconfig : --------------------------------------------------------------------- /> ifconfig eth0 192.168.1.122 ATSE: Waiting on PHY link ...... eth0 up, link speed 100, full duplex, eth hw addr 00:07:ed:0d:09:19 --------------------------------------------------------------------- but I still can't make a simple ping from or to the board... I think that my SOPC system or my Quartus assignements are wrong or maybe I choose the wrong interface between the PHY and the MAC so I post some screenshots : sopc system with tse and sgdma

I must tell that I'm a bit confused about how to solve this issue ! Thanks !! P.S : when I ping the board, I can see the RX and TX led blinking (I don't know if it is important to say it)

I think I'm using GMII. Can you get it to work with an example design on an evaluation board?

Actually, I'm not sure about this, ethtool disagrees:
Also it only seems to work when actually connected to a gigabit switch. I thought this was because of some debugging I was doing to try to get gigabit to work right, but I took that out and it's still broken.root:/> ethtool eth0 Settings for eth0: Supported ports: Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: external Auto-negotiation: on Current message level: 0x00000000 (0) Link detected: yes - Altera_Forum
hi,
do you have somebody some zimage, where ethernet work with cyclone iii system module dbm3c40 from company http://www.devboards.de ? i consider to use the board http://www.devboards.de/shop/artikeldet.php?proid=6437&bez=dbm3c40&sid=a8e41b8a36d55f0ed6ca93f42cd104b5&phpsessid=a8e41b8a36d55f0ed6ca93f42cd104b5 but without ethernet is for nothing. Thank you for answer. Jan Naceradsky, Czech Republic - Altera_Forum
you should confirm the interface mode,and make sure the corresponding work timing is correct, and you can test the timing when the ethernet is up by signal tap II! good luck!
