Re: [Qemu-devel] HDD problem with Xilinx virtex-ml507 board

[Lê Đức Tài]

Hi,

I have a new question about QEMU for virtex-ml507.
Can QEMU display X11 on this board?

Because I don't see any VGA output when remove "-nographic" option.
QEMU just display "monitor console" and "serial console".

Chủ đề: [Qemu-devel] HDD problem with Xilinx virtex-ml507 board

Hi,
I have a problem when emulating virtex-ml507.
Loop device can not be mounted as hda, no partitions are listed.

My environment is as following:

1. Qemu 0.14.1 build with libfdt support.

2. Kernel download from Xilinx Git server.
    config is customized from 44x/virtex_defconfig with enable some option to make kernel can automount filesystem:
    Under device drivers--->block devices:
    CONFIG_BLK_DEV_LOOP
    CONFIG_BLK_DEV_RAM
    CONFIG_BLK_DEV_NBD
    Under device drivers--->ATA/ATAPI/MFM/RLL support
    CONFIG_IDE_GD
    CONFIG_IDE_GD_ATA
    CONFIG_BLK_DEV_GENERIC
    CONFIG_BLK_DEV_PIIX
    Under file systems:
    CONFIG_AUTOFS_FS
    CONFIG_AUTOFS4_FS
    Also the ext2, ext3  file systems are supported

3. RFS is busybox

Run Qemu:
$ qemu-system-ppc -M virtex-ml507 -kernel vmlinux -m 256 -hda rootfs_ppc.ext2 -append "console=ttyS0 root=/dev/hda" -nographic
Output:
[    0.755969] NET: Registered protocol family 17
[    0.760477] hd: no drives specified - use hd=cyl,head,sectors on kernel command line
[    0.782726] Root-NFS: no NFS server address
[    0.782932] VFS: Unable to mount root fs via NFS, trying floppy.
[    0.790541] VFS: Cannot open root device "hda" or unknown-block(2,0)
[    0.792438] Please append a correct "root=" boot option; here are the available partitions:
[    0.795265] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

Can you help me for this problem?
Thank.
