Would be nice to give that you give the actual command line to try to use. I am using the stable-0.12 branch (plus some backporting patches for the MMU) to do development on sh4. HEAD still works correctly here. I am using the following command line: ~/git/qemu/sh4-softmmu/qemu-system-sh4 -M r2d -kernel zImage -drive file=sh4.img -serial null -serial stdio -usb -append "root=/dev/sda1 console=tty0 console=ttySC0,115200 noiotrap" -usbdevice keyboard -usbdevice mouse -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
