Compiler/AM5718: CPSW Ethernet issue

ALWALA MOUNIKA
Intellectual 280 points
Part Number: AM5718
Other Parts Discussed in Thread: PMP, TMP102

Tool/software: TI C/C++ Compiler

Hi Sir,

We have developed a custom board for am5718 using ti-processor-sdk-linux-am57xx-evm-05.02.00.10. We are able to completely boot upto root  but we are facing the ethernet problem and the phy is not getting detected and the link is not up as mentioned below and we have also mentioned the configurations we have done inorder to enable the ethernet but it didn't work out. So kindly have a glance at the dts configuration mentioned below and also through the boot log related to the ethernet and suggest how to move further.

    Hi,

    Thank you for posting the requested checklist information. I agree with your assessment that the link is not coming up. These are the 3 lines that matter the most here at the moment, the first one error is causing the following two lines that are listed.

    [    1.815792] davinci_mdio: probe of 48485000.mdio failed with error -5     <--- This is an IO error

    [   12.655508] net eth0: phy "48485000.mdio:09" not found on slave 0, err -19    <---- This is due to the mdio failure above

    Link detected: no     <----- This due to the previous two failures. Without a link the interface will not send packets.

    Are you setting the pin muxes DTS values in u-boot or Linux? They should be set in u-boot. Depending on if your board is based closely on one of the  AM57x boards  you could reference that for your DTS entries. Did you base your board of a TI board? One debug step might be that there is a clock coming out at all on the MDIO bus. 

    Best Regards,

    Schuyler

    Hi Sir,

    We are not able to get the mdio clk signal and that too when we scope that signal it remains continuous high. So what modifications should we do to get the clock.

    Thanks and Regards,

    Hi, 

    With no clock that could be a pin mux issue. Could you attach the full boot log and the section of the schematic showing the connection to between the MAC and the PHY?

    Thank you,

    Hi,

    We are getting the Mdio_clk but phy is not detected and the Mdio_data is continuous high. Please find the schematic related to phy in the above mail and find the boot log below. Kindly help on this to resolve the issue.

    Hi,

    Thank you for posting the requested info. Concerning the schematic snippet only has the data lines connecting to the PHY, I need to see the MDIO lines too, could you please re-post the picture showing the connection between the MDIO pins of the TI device and the PHY?

    I will be out of the office until the week of the 12th.

    Best Regards,

    Schuyler

    Hi,

    The phy got detected and the Ethernet is working file, there was problem with CONFIG_IODELAY_RECALIBRATION in board.c file. when we make below changes it's working.

    board.c :-

    #ifdef CONFIG_IODELAY_RECALIBRATION
    void recalibrate_iodelay(void)
    {
        const struct pad_conf_entry *pconf;
        const struct iodelay_cfg_entry *iod, *delta_iod;
        int pconf_sz, iod_sz, delta_iod_sz = 0;
        int ret;

            pconf = core_padconf_array_essential_am571x_idk;
            pconf_sz = ARRAY_SIZE(core_padconf_array_essential_am571x_idk);
            iod = iodelay_cfg_array_am571x_idk;

            iod_sz = ARRAY_SIZE(iodelay_cfg_array_am571x_idk);

        /* Setup I/O isolation */
        ret = __recalibrate_iodelay_start();
        if (ret)
            goto err;

        /* Do the muxing here */
