When the Linux is loaded after couple of minutes I see this message.

[  268.626084] omap-mailbox 48840000.mailbox: Try increasing MBOX_TX_QUEUE_LEN
[  268.633088] omap-rproc 58820000.ipu: PM mbox_send_message failed: -105

What can be a reason and how to resolve it?

This is my boot_log:

  • Hi Oleg,

    Couple of questions:

    1) Is this a custom IPU firmware that you are using?
    2) Any specific changes that you have done on custom am5749 board w.r.t IPU device tree?
    3) Does this come by default SDK boot up for you?

    Best Regards,

    Hi Keerthy,

    I use ti-processor-sdk-linux-am57xx-evm- on am5749(custom board).

    1.I didn't use  custom IPU firmware.

    2.I didn't make any changes in device tree pertaining to IPU. I only change TLK105L on DP83822IF and add couple of drivers sata in kernel (just change m on Y).

    3.I am using default sdk. Actually I am not sure when it is started ...bord was turned on for 2 hours aproximatly.

    Best Regards,

    Hi Oleg,

    Are you running any application involving remote cores?

    If so, please let us know the application details.

    If the behavior is with default SDK, please share steps to reproduce the behavior.

    Thanks & Regards,
