Triple Speed Ethernet - uClinux

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.  

 

 

Daniel
