Subject: | [Qemu-discuss] Guest host 2 ways serial communication not working |
Date: | Sun, 2 Jun 2013 21:56:02 -0400 |
Hi,
I posted not long ago an issue about getting Input/output
error while trying to use ttyS0 in the guest.
The purpose of this is to establish a communication
serial link between guest and host. I did some reading on some af the discution
already on and tryed something new:
sudo qemu-system-arm -M beaglexm -m 1024 -sd ./test.img -clock unix -serial
stdio -device usb-mouse -device usb-kbd -chardev pty,id=mypty -device
omap_uart,chardev=mypty,baudrate=9600
when
qemu launches I get this message:
char
device redirected to /dev/pts/1 (label mypty)
What I read about is that -chardev pty,id=mypty should be my host
side In point to the guest and that -device
omap_uart,chardev=mypty,baudrate=9600
should be my Inpoint to the host. basicly the serial communication should
be easely done by opening /dev/pts/1 on the host side and /dev/ttyO0 on the
guest side to begin the
communication. (Im using minicom on the host side and picocom on the guest
side).
Well, any of this is working and Im strting to lose faith in this project
to work.
Thank in advance for anyone who can help me
