Hi,

I have been trying to achieve auto-neg by following the bootstrap configuration below.

RX_D2=High

RX_D0=Low

RX_ER_GPIO=LOW

RX_D4=Low

I am able to achieve 1000mbps by command but not auto-neg. Whenever the ethernet is connected, the auto-neg sets it to 10mbps.

How do I change the configuration so that I am able to achieve 1000mbps with auto-neg?

Thank you in advance!

Regards,

Jeevan

Hi Jeevan,

What do you mean by "I am able to achieve 1000mbps by command"

Please send me a register dump of registers 0x00-0x1F.

Thanks,

David

Hi David

/usr/sbin/ethtool -s eth0 speed 1000 duplex full autoneg on
Using the above command we were able to achieve 1000 mbps.
I have attached the  Schematic of the ethernet circuit used for more clarity.8750.Ethernet.pdf

Thankyou,

Jeevan

Hi Jeevan,

Please send me a register dump of registers 0x00-0x1F, 0x467, and 0468, before and after running that command.

Thanks,

David
