Hi Mr.Daixiwen,

actually i am measuring all the clocks belongs to the Marvell 88E1111 IC. according to the datasheet they have given that RX_CLK, TX_Clk are 2.5 MHz, 25MHZ. but for the TX_CLK i am not getting either 2.5KHz nor 25 MHz. As i measured at the MDIO pins there i am getting pulses with 4KHz. and i measured the reset pin and got correct only for reset pin. as of i tested this board 1 week before that time i didn't get any problem, that time connection establishment happen and pinging also done. now only i am getting this problem that when i am connecting to the PC it is not showing connection. can u please help me out what is the main problem for this and how to rectify this one.

Thank You,

Mamta
