Re: Loading Cpio (gz) image as rootfs

[Benoit RAT <benoit@xxxxxxxxxxxxx>]

Sorry to bother again but I found the solution. maybe it can help someone:

initrd need start and size parameters. 

As, size can be bigger then real size of image.cpio.gz, I set it to 32M like the addpart command.

bootargs="$bootargs initrd=0x72000000,33554432"

Hy everybody,

I was wondering if it was possible to load a cpio.gz image as rootfs! (I think it is the kernel that load it so it should not be a problem)

however I don't know how to pass the arguments.

Here you can find the commands, that i am using:

addpart /dev/mem  8M@0x71000000(kernel);

tftp zImage /dev/mem.kernel

addpart /dev/mem  32M@0x72000000(fs)

tftp image.cpio.gz /dev/mem.fs 

bootargs="$bootargs root=/dev/ram0 initrd=0x72000000"

bootz /dev/mem.kernel

Regards,
