ml605 ethernet how to switch to 1000Mb/s mode

Jump to solution

I'm using V6 ml605 board tesing  the ethernet connection with pc, under EDK14.3, I tested xilinx lwip(xa1026) example, the 10Mb and 100Mb works well sending and receiving, the auto negotiated link speed showed 100, 

How should I set to 1000Mb/s mode? I tried to change BSP settings in lwip140, but then the board is not responding to pc after applied the settings, I've added the hard emac in xps for 1Gb/s ethernet, so are there other settings caused my error?

Is your PC an old one ?.

 

1) The 1000 mbps mode is not supported by many old machines . Normally before two devices finalise on the a mode 

    10/100/1000 they advertise thier capabilities.

2) Another possibility is the clock provided as the source clock to this module needs to be a specific speed (check data

   sheet) for it to support 1000 mbps.

 

Hope this helps.

thanks, yes the problem is as you said, I tested on other platform and sucessed in gigabit mode,

my ethernet card on pc was 100Mb so it's limited.
