Hi, Im trying to test virtio-mmio too but Im having no success to boot vexpress-a9. kernel: Linux 3.10-rc6 -> vexpress_defconfig qemu: 1.6.0-rc0 cmd line:
qemu-system-arm\ -m 512\ -M vexpress-a9\ -kernel arch/arm/boot/zImage\ -initrd boot-kernels/initrd-modified.img \ -append "root=/dev/mmcblk0p2 console=ttyAMA0 rootwait debug earlyprintk"\ -sd /exports/vexpress/vexpress-a9-nano.img\ -monitor unix:/dev/tty1,nowait,server\ -serial stdio\ -d in_asm,cpu -D /tmp/qemu.log -singlestep Here I get the 'total no output' error. I tried with vexpress-v2p-ca9.dtb and from 'remotes/linaro/v3.9/vexpress' but got the same. With, qemu-system-arm\ -m 512\ -M vexpress-a15\ -kernel arch/arm/boot/zImage\ -initrd boot-kernels/initrd-modified.img\ -append "root=/dev/mmcblk0p2 console=ttyAMA0 rootwait debug earlyprintk"\ -dtb arch/arm/boot/dts/vexpress-v2p-ca15_a7.dtb'\ -sd /exports/vexpress/vexpress-a9-nano.img\ -monitor unix:/dev/tty1,nowait,server\ -serial stdio The kernel boots, but it cant mount the SD: mmc0: host doesn't support card's voltages mmc0: error -22 whilst initialising SD card SD: Unknown CMD1 Am I missing something?? Kind Regards, Erlon
