Hello,
I am using the Altera Cyclone V GT Development Board (5CGTFD9E5F35C7N FPGA). I am successfully running uClinux (Linux version 3.1) on the board. In my Qsys design I added an Ethernet system with Triple Speed Ethernet (TSE), sgdma_bridge, sgdma_rx, sgdma_tx and descriptor memory. I have set the TSE Interface to RGMII, because the PHY-to-MAC interface of my board employs a RGMII interface. Does uClinux support RGMII? I made the kernel configuration according to http://www.alterawiki.com/wiki/ethernet [*]Altera Triple Speed Ethernet MAC support(SLS) [*]Drivers for Marvell PHYs After booting uClinux I can assign a MAC- and IP-address: > Ifcongfig eth0 eth0 Link encap: Ethernet HWaddr 00:07:ED:0A:03:39 inet addr: 192:168:1.123 Bcast: 192.168.1.255 Mask 255.255.255.0 RX packets:19 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Collisions:0 txqueuelen:1000 Base address:0x2800 However I cannot ping the board to and from the Host-PC. Can anyone help me? Is the RGMII the problem? Any advice is appreciated. DanielLink Copied
