Hello,

If we don't use RTC and we use the arago-base-tisdk-image-am335x-evm filesystem
How to clear the following hwclock error message


....

irectory
bootlogd.

    Hi Justin,

    I assume this is called from one of the init scripts located in /etc/init.d (hwclock.sh). You can remove it from the runtime control with:

    sudo update-rc.d -f hwclock.sh remove

    Please let me know if this fixes your problem.

    Best regards,
    Miroslav

    Hello Miroslav,

    I delete the link S20hwclock.sh in /etc/rc5.d,then i make the ramdisk.gz

    it still show following message

    Justin,

    I found another init script that is calling hwclock.sh:

    /etc/rcS.d/S55bootmisc.sh

    # Set the system clock from hardware clock
    # If the timestamp is more recent than the current time,
    # use the timestamp instead.
    test -x /etc/init.d/hwclock.sh && /etc/init.d/hwclock.sh start
    if test -e /etc/timestamp
    then
        SYSTEMDATE=`date -u +%4Y%2m%2d%2H%2M`
        read TIMESTAMP < /etc/timestamp
        if [ ${TIMESTAMP} -gt $SYSTEMDATE ]; then
            date -u ${TIMESTAMP#????}${TIMESTAMP%????????}
            test -x /etc/init.d/hwclock.sh && /etc/init.d/hwclock.sh stop
        fi
    fi

    I think this is it, because the error messages appear before you enter runlevel 5.

    Best regards,
    Miroslav
