When running from EMMC we get the following stack dump, but when running from SD card the the startup trace is clean:

Otherwise, the system seems to be in working order after startup. Other than being disturbing to see during boot, this error appears to have no effect.

In any event, it would be nice to know the root cause of the error in order to eliminate it, just in case it is having some latent adverse impact on the system.

Thanks,

Weston

    Hi Weston,

    This is a custom board, right?
    Which SDK release are you using?

    Best Regards,
    Yordan

    Hi Yordan,


    Yes, this is a custom board. With respect to the SD card and eMMC circuits, It follows the TI reference design for the AM5728 EVM very closely.


    We are using the 2.00.02.11 SDK release for our kernel with an updated u-boot, which is newer than the 03.00.00.04 SDK release (TI-SDK remotes/origin/ti-u-boot-2016.05, SHA: b43cf45fec75961d196da4563bd32c0215d2fd58).

    Thanks,

    Weston

    Hi Weston,

    Apologies for the delay.
    Please provide the full bootlog. Also the dts for your custom board..

    Check for duplicated interrupts in dra7.dtsi.
    If not needed try removing the rtc nodes from your dts (I've seen this used a workaround in older sitara devices, so it could be worth trying).

    Best Regards,
    Yordan

    Hi Yordan,

    We do not explicitly add new interrupts in our board's DTS file, so I don't think we have created duplicate interrupts.

    We use an RTC in our design, so unfortunately removing the RTC nodes is not an option for us.

    Attached is a full boot log containing the stack trace.
