Hi team,
my customer found DP83640 auto MDIX issue, when their board connect to computer, it can work good. when two board connected by switch, it can also work good, but if this two board connect directly(TD to TD, RD to RD), it can not works, but customer found auto MDIX function is already enable by defult, so could you help to share some more comments why this happens?
Thanks very much.
Regards, Sunny
