Hi Chris,
1.The rootfs is fedora12 which is for arm I download from offical
website.
2.I used serial port on my PC to connect my board(freescale imx5)
and I boot my board through NFS Server.
3.I am using Fedora13 on my PC.
4.I am using "minicom" to communicate.
And now,I want to use "minicom" to communicate my board,like using
some commands in shell,but I cannot login the shell on my PC,I cannot
input the count and password,I can only login by my board.
Thanks!
Login over serial is controlled by files in /etc/events.d
If your serial connection is defined as the primary console (usually
through a console= argument on the kernel boot line),
then /etc/events.d/serial should detect this and offer a login on that
line. Otherwise, copy one of the existing ttyX scripts and modify it:
cp /etc/events.d/tty1 /etc/events.d/ttyS0 # or whatever the port is
Then change the mingetty to an agetty command, with appropriate
arguments for serial port speed and so forth, perhaps something like:
/sbin/agetty -L 115200 ttyS0
or
/sbin/agetty-L 9600 ttyS1
...depending on the particular port you're using.
I'm unclear from your e-mail -- if the problem is that you're seeing the
login prompt but can't type anything, check to make sure that hardware
flow control is disabled in minicom.
