Hi,
I have built the freescale linux image (for my custom board using
iMX6Q) fsl_L.3.14.28-1.0.0_ga. While building I added few more
packages like rpm, opkg, e2fsprogs, etc.
The startup scripts do not show std output on the serial console
(ttymxc0). The output is likely redirected to /dev/null. They only sow
errors. Which setting (file) has to be modified to get the output on
the serial console?
Any inputs will be of help.
Regards, Pj

Take a look in the difference between file imx6sabresd-common.inc and
imx6sabreauto-common.inc
Maybe it can help you

Thanks Daiane for your inputs!
The link you pasted indicates that correct serial port must be specified.
I have ensured that correct serial port is set (/etc/inittab) . I can
see the errors but I cannot see the stdout.
I think there is a setting for verbosity, which is set to quiet. I'm
not sure though.
FYI: I also have installed procps package.
I modified the file /etc/init.d/bootmisc.sh:
original line: eval /sbin/sysctl -p "${SYSCTL_CONF}" $VERBOSE_REDIR
edited line: eval /sbin/sysctl -p "${SYSCTL_CONF}"
(VERBOSE_REDIR is set to "1>/dev/null")
After the above modification, I can see script stdout while system
reboot or shutdown, but I cannot see the same during system startup.
Any idea what am I missing?

I have built the yocto image again (fsl_L.3.14.28-1.0.0_ga) (framebuffer)
I verified the file:
fsl-L3.14.28-1.0.0_ga/fsl-release-bsp/sources/meta-fsl-arm/conf/machine/include/imx6sabresd-common.inc
correct console device and baud rate is selected (ttymxc0).
I have installed extra packages by adding the following line to conf/local.conf:
CORE_IMAGE_EXTRA_INSTALL += " rpm opkg freetype createrepo
libsocketcan ntp parted cairo curl python-pycurl expat harfbuzz htop
pixman tslib e2fsprogs fontconfig pango glib-2.0 opkg-utils sqlite3
python-pysqlite libcurl bzip2 dropbear python-smartpm tzdata
python-debugger python-difflib python-sqlite3 connman connman-client
e2fsprogs-tune2fs lsof msmtp iptables "
I do not see the init scripts log on the serial console (during
startup). There is no issue with console configuration as the init
scripts show log during shutdown/reboot.
If I run "ps eax", I see the following (partial output shown here):
1424 ? Ss 0:00 /lib/udev/udevd -d CONSOLE=/dev/null
display_lvds0= display_lvds1= SHELL=/bin/sh TERM=linux prevlevel=N

I edit the file: /etc/init.d/rc and exported CONSOLE=/dev/ttymxc0.
When I reboot the system and re-run "ps eax" I can see the CONSOLE env
getting correctly updated. But still no output on the serial log.
Any inputs what may be going wrong?
I'm kind of stuck here. Any information might be of help to me.

I forgot to add one important point: I'm still using old linux kernel 3.0.35+.
But I'm hoping that should not create this problem.

What is your boot command line?
# cat /proc/cmdline
It should be something that contains 'console=ttymxc0'

Are you really running the console at 57600 baud? The default
is normally 115200. What's in your /etc/inittab? e.g. send
the output from this command:
# grep mxc0 /etc/inittab
mxc0:12345:respawn:/sbin/getty -L 115200 ttymxc0

Yes, I'm using baud rate of 57600.
/etc/inittab is also updated.
I think I may have found the problem. I'm not sure though.
udev is not creating /dev/stdout & /dev/stderr links.
It creates /dev/stdin link file.
I don't know how to fix this. I manually created the links but it does
not solve the problem.
Any ideas?
