RE: Creating RAM disk on ARM9

[Fabrizio Grasso <f.grasso@xxxxxxxxx>]

Thanks.
I'm just using busybox ver 0.60.5 but it doesn't include any mke2fs command 
and it's not possible to include that.
Under /dev/rd path I found 16 directories (from "0" to "15") which probably 
correspond to memory areas.
I tried to mount as ramdisk one of that and I corrected obtained a /mnt/ 
path. Now I can read/write to that.

But...
where to specify the corrispondence from each /dev/ directory to memory area.
If I solve this.. probably I'll be able to mount the specified ram area as 
ramfs.

Thanks
