DM8168 Linux kernel bring up problem

Other Parts Discussed in Thread: PMP

Hi,

We are using dm8168 processor of 2GB DDR3 with UART0 configuration and 531 clock frequency.

We built linux kernel with CONFIG_REGULATOR_GPIO is not set and  CONFIG_REGULATOR=y.

Now we are facing a problem while linux bring up.

Here is a LOG:

Here after we are not getting any print messages on UART0.

Help is appreciated.

    I noticed that there is ecc issue in the log. Could you check that? try modifying the ecc alg, e.g.

    Also check if your kernel bootargs has correct setting for console=ttyO2

    Wang and Narayanan Thanx for the reply.

    That issue is solved now.

    We are using UART0,so we used ttyO0 and 0x81000000 as uImage loading address.

    And did SD configuration and PHY configuration for our new board.

    That ECC uncorrectable error is solved by erasing whole nand  chip.

    Now iam facing eth0 ping problem.

    2 phy's are used:phy 0:01 and phy 0:02

    etho is configured as phy 0:01

    eth1 is configured as phy 0:02

    eth1 is working properly,eth0 is not receiving packets.

    Do i need to configure anything else?What is the problem here?

    Help is appreciated.

    Here iam attaching the LOG:
