Subject: Serial consoles

Message-ID: <4F14AF2F.9040003@gmail.com> (raw)
I'm using a Marshalltown Cedarview board and it's serial ports are
standard PC com1 and com2 so I put the following in my
conf/machine/mycdv.conf file, where mycdv is the name of my machine/bsp,
i.e. meta-mycdv.
SERIAL_CONSOLE = "115200 ttyS0"
SYSLINUX_OPTS = "serial 0 115200"
APPEND = "console=ttyS0,115200 console=tty0"
When the system booted, I have the kernel console on com1 and I also got
a login prompt on com1. However, the syslinux output was only displayed
on the VGA monitor.
Anyone know why? Maybe SYSLINUX_OPTS goes somewhere else?
I noticed in the n450 release notes that they accomplish this with the
following in the local.conf file:
# Serial Port Setup for Intel Embedded Development Board 1-N40\
SYSLINUX_OPTS_atom-pc = "serial 0 115200"
SERIAL_CONSOLE_atom-pc = "115200 ttyS0"
APPEND_atom-pc = "console=ttyS0,115200 console=tty0"
This does work for the N450, but the cedartrail bsp is not under
standard/common-pc/atom-pc. It's under standard/cedartrail. If I have
to put SYSLINUX_OPTS in local.conf, what is the suffix and why???
