Issue with AM1808 + DP83848J PHY driver on linux

Gururaj P

Other Parts Discussed in Thread: AM1808, DP83848J, OMAP-L138, DA8XX, PMP

Hi,

We are working on AM1808 platform with linux kernel version 2.6.33. We are having below ethernet driver issues:

1. As Our custom board is having Ethernet DP83848j phy chip, as driver for DP83848j phy is not supported in linux kernel version. Could you please share the driver for DP83848J phy?

2. We have below set-up for debugging Ethernet inteface:

Once linux comes up on custom board, having Ethernet cable connection from board to laptop with static IP, we are not able to ping from board interface to laptop.

Could you please help on the above problem?

Hi Gururaj,

Once linux comes up on custom board, having Ethernet cable connection from board to laptop with static IP, we are not able to ping from board interface to laptop.

Could you please share your complete bootup log ?

Are you able to access the ethernet in u-boot like tftpboot etc., ?

Hi Titus S,

Appriciate your quick response.

We are able to access the ethernet in u-boot mode (using tftp).

Its is not working from once linux boots.

Please find the attached log below

Hi Gururaj,

Please don't text paste the logs in post but attach the logs.

Have you enabled "MDIO" support in linux ?

I'm not able to see any MDIO logs in your bootup log.

Ex:

davinci_nand davinci_nand.1: controller rev. 2.5
davinci_mdio davinci_mdio.0: davinci mdio revision 1.5
davinci_mdio davinci_mdio.0: detected phy mask ffffff7f
davinci_mdio.0: probed
davinci_mdio davinci_mdio.0: phy[7]: device davinci_mdio-0:07, driver SMSC LAN8710/LAN8720

Have you changed board file for MDIO and EMAC support with pinmuxing ?

Also please look into the below problem that EMAC PSC got power down due to not using the EMAC clocks.

Clocks: disable unused emac

We may need the below EMAC and MDIO configurations like below code snippet.
