uClinux Boot problem

Hi All,

Does nobody help me?

I read the start-up text and find that

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize[/b]

--- Quote End ---

Here, I do not know why use RAMDISK driver, I also can not find it during Kernel config.

Then, display

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

VFS: Mounted root (romfs filesystem) readonly.

Freeing unused kernel memory: 64k freed (0x99c000 - 0x9ab000)

expand: from=/ramfs.img to=/dev/ram0

expand: from=/ramfs.img to=/dev/ram1[/b]

--- Quote End ---

Here, I know romfs has been mounted. But, ramfs.img can not be expanded. So, the boot process can not continue anymore. I do not know why here can not be expanded.

Can help me?

Thank you,

LiangYi
