Re: [Qemu-devel] Using virtio-mmio

[Erlon Cruz]

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
