[Qemu-discuss] qemu-system-arm error when emulatting firmware

[poxyran]

Hi all!,

I'm trying to emulate a firmware from a DLink IP camera using
qemu-system-arm but I'm facing some troubles.

I'm using the following command line:

address@hidden:~/QEMU/armel$ sudo qemu-system-arm -M versatilepb -kernel
vmlinuz-2.6.32-5-versatile -initrd
/home/fastix/dcs-942l/binary_blob.bin.swap_unpacked/initramfs.cpio -hda
debian_squeeze_armel_standard.qcow2 -serial stdio -append
"root=/dev/sda1 console=ttyAMA0 console=ttyS0 init=/bin/ash" -net nic
-net tap

Even though I get some errors related to devices that are not present,
the firmware seems to boot OK but at the end, I got the following error:

starting pid 11724, tty '': '/bin/sh < /dev/ttyS0 2>&1 > /dev/ttyS0'
/bin/sh: can't open /dev/ttyS0: no such file[: bad number

Is there any way to fix this?.

Thanks in advance,
