Using a DN2800MT (Marshalltown) Intel board, I'm testing the
meta-cedartrail using edison branch and noticed an issues with the
serial console.
The cedartrail.conf in the machine directory has the following statements:
SYSLINUX_OPTS = "serial 0 115200"
SERIAL_CONSOLE = "115200 ttyS0"
APPEND += "console=ttyS0,115200 console=tty0"
However, when the image booted, I had no serial console on ttyS0. I
checked /etc/inittab and noticed that the following line existed:
S:2345:respawn:/sbin/getty 115200 ttyS3
I changed the ttyS3 to ttyS0 and then I have a serial console on the
next reboot. So it appears the override in the .conf file is not
working. Also I only have the console from getty, and not the kernel
logging console.
Anyone have a solution??
If this is considered a bug I can put it on bugzilla.
Lets make sure your environment is what we expect. Please provide the
output of:
$ bitbake core-image-minimal -e | grep SERIAL_CONSOLE=
If it is not "115200 ttyS0" then it is getting overwritten somewhere
either in your config, or possibly by an inappropriate selection of an
assignment operator (=, ?=, etc.) in edison.
okay now I'm confused. while the cedartrail.conf file has the following:
SYSLINUX_OPTS = "serial 3 115200"
SERIAL_CONSOLE = "115200 ttyS3"
APPEND += "console=ttyS3,115200 console=tty3"
The output of the bitbake command you suggested above gives:
jim@ubuntu-x64:~/poky/build$ bitbake core-image-minimal -e | grep
SERIAL_CONSOLE=
# SERIAL_CONSOLE=115200 ttyS0
SERIAL_CONSOLE="115200 ttyS0"
jim@ubuntu-x64:~/poky/build$
So is the bitbake command showing the results before the cedartrail.conf
options take affect??
