Linux/BEAGLEBK: Beaglebone Black Yocto build warning

Part Number: BEAGLEBK

Tool/software: Linux

Hi,

I had a warning when building images for BBB using am335x-evm machine on Yocto build system:

$bitbake core-image-minimal

...

WARNING: core-image-minimal-1.0-r0 do_rootfs: [log_check] core-image-minimal: found 1 warning message in the logfile:
[log_check] warning: %post(sysvinit-inittab-2.88dsf-r10.am335x_evm) scriptlet failed, exit status 1
...

NOTE: Tasks Summary: Attempted 2297 tasks of which 2250 didn't need to be rerun and all succeeded.

Summary: There was 1 WARNING message shown.

Although this does not really affect my build results. I wonder if anyone has seen the same warning. Question: What this is and if there is a way to get rid of the warning?

Thank you.

    Hello Matt,

    This warning is caused by your custom service. Please, check your custom service files for typos and discrepancies.

    Best regards,

    Hi Kemal,

    Sorry about the late reply, I am not sure if I understand you correctly... Do you mean the warning is caused by one of my scripts /etc/init.d? Or you mean other files? Please explain.

    In this case, I built core-image-minimal using the recipes from Poky and meta-ti. My customized Yocto layers and other scripts are not added. So I just want to be sure what are the exact files I should look.

    Thank you.

    Yes, I mean your scripts in /etc/init.d/. Can you share your exact configs for Poky and meta-ti? I cannot reproduce this warning with the Processor SDK OE layer configs.

    Hello Matt,

    Please, try to build from scratch or on another host computer. I've just built with the exact configurations as yours and no such warning appeared.

    Best regards,

    Hi Kemal,

    Thank you for the message.

    I built from scratch and also tried a different build machine (CentOS rather than Ubuntu). They both have the same warning. However, after digging a bit more, it looks like the warning is caused by the pkg_postinst_${PN} of sysvinit-inittab-2.88dsf.bb. This seems to be addressed in Yocto 2.5: www.yoctoproject.org/.../ref-manual.html
    4.13.6. Miscellaneous Changes
    ...
    "* Using exit 1 to explicitly defer a postinstall script until first boot is now deprecated..."

    So I will just treat it as a warning that can be ignore. Please let me know if you have insights about this.

    Thank you for you help!
