[Qemu-discuss] Guest host 2 ways serial communication not working

[FRNC RAMS]

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
