Hi,

 

we have custom board based on T1024RDB with serdes configuration 0x95. There are two 1G Ethernet interface and one 10G optical interface. 10G optical interface is not coming up in this board.

=> mdio list
FSL_MDIO0:
0 - Marvell 88E1510 <--> FM1@DTSEC4
1 - Marvell 88E1510 <--> FM1@DTSEC3
FM_TGEC_MDIO:
2 - Generic 10G PHY <--> FM1@TGEC1

=> mii device
MII devices: 'FSL_MDIO0' 'FM_TGEC_MDIO'
Current device: 'FSL_MDIO0'

=> mii info
PHY 0x00: OUI = 0x5043, Model = 0x1D, Rev = 0x01, 1000baseT, FDX
PHY 0x01: OUI = 0x5043, Model = 0x1D, Rev = 0x01, 10baseT, HDX

=> mii device FM_TGEC_MDIO
=> mii device
MII devices: 'FSL_MDIO0' 'FM_TGEC_MDIO'
Current device: 'FM_TGEC_MDIO'

=> mii info

When I run "mii info" command for  FM_TGEC_MDIO bus, there is no output. My XFP module is present in the board,it should show phy address. Can you please help me to debug this issue? EMI2_MDIO and EMI2_MDC signals are going to WPCS4227C chipset. Please see here attached schematic for H/W connections and signals.

 

Thanks & Regards,
