I have been trying for a couple of weeks now to get cramfs to work on a
SA-1110 board. My development platform is running a 2.2 kernel, and the
SA1110 is running a 2.4.0 rmk2 kernel. My goal is to load the cramfs image
into memory on the StrongARM board and mount it as the root device as a
ramdisk. Originally, I kept getting the message "wrong magic," but then I
booted the kernel with the parameter "ramdisk_blocksize=4096", which in some
cases will give me the message "cannot find init", and much more commonly
will give the error:
VFS: Mounted root (cramfs filesystem).
Freeing init memory: 44K
attempt to access beyond end of device
01:00: rw=0, want 2950544, limit=4096
attempt to access beyond end of device
01:00: rw=0, want 2950548, limit=4096
attempt to access beyond end of device
01:00: rw=0, want 2950552, limit=4096
Error -3 while decompressing!
Is it possible that the mkcramfs that I have needs to be modified to make
images that will work on a SA1110 platform?
Any insight that anyone could give me into what might be going on with this
would be greatly appreciated! Please let me know if I have left out any
important details. Thanks very much for your help!
