Hi,

 

We are working on I.MX8mmini Ethernet IC DP83848 and ethernet is not getting detected

 

We have enabled the TI DP83848 Driver  as below

Menuconfig location

Symbol: DP83848_PHY [=y] 
Type  : tristate
Prompt: Driver for Texas Instruments DP83848 PHY  
Location:     -> Device Drivers      
                  -> Network device support (NETDEVICES [=y])
                  -> PHY Device support and infrastructure (PHYLIB [=y])  
Defined at drivers/net/phy/Kconfig:144  
Depends on: NETDEVICES [=y] && PHYLIB [=y]


Log, driver source code  and Schematic of Ethernet Section is attached for your reference

We had used the i.mx8mmini EVK configuration and now enabled the above drive,
but we are not see the driver getting loaded in the trace. We are trying to configure
the Ethernet Phy for MII mode dDo let me know how to setup the MII mode and how to
enable and test the Ethernet driver

Regards 
Santhosh
