[Qemu-devel] MIPSEL emulation is broken in svn

[Qemu-devel] MIPSEL emulation is broken in svn

Hi everyone,

I check out the current qemu code in svn(version 6311 )  and compiled it using gcc 3.4 in ubuntu 8.04 for mipsel emulation. I follow the steps in http://www.aurel32.net/info/debian_mips_qemu.php.

1. ./configure --target-list=mipsel-softmmu
2. cd mipsel-softmmu
3. ../qemu-img create -f qcow hda.img 10G 
4. $ wget http://ftp.de.debian.org/debian/dists/etch/main/installer-mipsel/current/images/qemu/netboot/vmlinux-2.6.18-6-qemu 
    $ wget http://ftp.de.debian.org/debian/dists/etch/main/installer-mipsel/current/images/qemu/netboot/initrd.gz 

5. ./qemu-system-mipsel -kernel vmlinux-2.6.18-6-qemu -initrd initrd.gz -hda hda.img -append "root=/dev/ram console=ttyS0" -nographic


But there is no serial put on console. 

I try it on qemu 0.91 and it works.

I wonder whether the mipsel emulation of current svn version of qemu is broken?


Thanks & Regards

No, it is not, it's just that the default emulated machine has changed.
Try adding '-M mips' to the arguments.
