emac1 speed

Hi ALL,

 

         We use TI's latest PSP(04-01-00-06) on our TI8148EVM,and we use emac1 when mounting rootfs ,the PHY device is RGMII interface.now the kernel could work with NFS,but it seems the speed of ethernet is only 10Mbps(the PHY device support 10/100/1000Mbps),below is part of the log:

PHY 0:00 not found

CPSW phy found : id is : 0x4dd074
Sending DHCP requests ...
PHY: 0:01 - Link is Up - 10/Full
., OK
IP-Config: Got DHCP answer from 0.0.0.0, my address is 192.168.0.101
IP-Config: Complete:
     device=eth0, addr=192.168.0.101, mask=255.255.255.0, gw=192.168.0.1,
     host=192.168.0.101, domain=domain, nis-domain=(none),
     bootserver=0.0.0.0, rootserver=192.168.0.162, rootpath=
VFS: Mounted root (nfs filesystem) on device 0:14.
devtmpfs: mounted
Freeing init memory: 196K

But that may be not fast enough for my video application,any idea about change the speed to 100/Full?

Thanks and Regards,

XiangW

    Try looking at the capability of either the switch or router that you are plugged into only supporting that speed. Not familiar with this board and how it might be setup, the PHY may be configured to only connect at this speed. Typically auto negotiated between the PHY and other end device.  As a means of verification try plugging a laptop into the port that the EVM is plugged into and see if you get the same speed.
