Hi everyone,
I want to use ramdisk to boot my filesystem, as I can't use NFS and harddisk.
I have load the ramdisk into the ram memory (start address :0x4000000)
and in the boot options I specified : root =dev/ram0 initrd=0x4000000
but the kernel said it can not find any file system on it.
Here is the information I can supply :
U-Boot 1.2.0 (Aug 31 2007 - 20:54:55)

Who can give me some hints ? or point me some direction to handle this.
I appreciate this very much.

Looking at the information below, did the program which loaded the
filesystem into RAM decompress it? It noted that it was compressed so I
would assume so, but I am unfamiliar with ARM tools, so I ask the
question. Also, should the boot device be "/dev/ram0" rather than
"dev/ram0" or is that correct for your system?

thanks for the reply.
no , it is not decompressed. isn' t the kernel supposed to do that? As
we have tried to load this filesystem on the pc, it turns out the the
kernel can recognize it.
concerning the root=/dev/ram0,
as the default value is root=/dev/nfs, so I just modify the nfs to
ram0. is this might be a problem?

Hopefully someone who works with this regularly can provide some
answers, the only time I used booting into a RAM-only system the tools
which I had "just worked" and I followed the steps outlined without
fully understanding the details. However, I just tried loop mounting a
compressed filesystem and that didn't work, while decompressing into a
ramdisk and mounting worked fine. That's why I asked if your tool was
just copying to RAM without decompression, since I have no ides what
tool you use.
As for the name, your original post used "dev" without a leading "/" and
while I assumed it was a typo, I thought it was worth mentioning since
you were looking for suggestions. I would expect /dev/ram0 to be correct.
I would try the decompressed image next, and I have no other ideas at
the moment.

Since you don't know what the default directory is, perhaps
root should be /dev/ram0. Also, make sure you actually create
those device nodes in /dev

Hi Dick,
Thanks for the reply.
then how to create these device nodes in /dev? from the information i
got from the cosole(unknown block(1,0) ), it seems that I didn't
create the device? I thought the kernel should do this work right? if
not how to create it?
thanks,

Do this in the file-system you create for the RAM Disk.

Hey Dick,
where exactly (on which file system) is Xu supposed to create the device
nodes? ;-)
Xu's problem is, he can't mount his _root_ filesystem in the first place.
Therefore I doubt it'd help to have some device nodes somewhere ...
Xu,
all answers to your posting commented on your kernel command line. The command
line you quoted contains "root =dev/ram0".
You probably meant to write "root=/dev/ram0". To not waste our time, please
clarify if this was a typo before asking further questions.
regards,
Uli

Hi Uli,
yes, it is my mistake. actually in the boot option line It was
root=/dev/ram0 . sorry for the misleading.

then is there any new hint about that?
I didn't do the memory patition , would this cause the problem?

Hi Xu,
As far we have worked on it, the parameter to be passed is
"root=/dev/ram" and not "root=/dev/ram0". Atleast I used it to boot
the kernel on a U-Boot boot loader.
I guess I can help you out. But I will need more details. But I
would like you to try "root=/dev/ram" first and let me know if its
working.
Midhun.
