Hi
I have a device with intell flash 32MB.
However as a research work I wanted to limit that to 2mb.
out of which 0x00140000 is used for kernel and ramdisk storage.
So I used
static struct mtd_partition shasta_partitions[] = {
{
name: "Bootloader/Kernel",
size: 1024*1280,
offset: 0,
mask_flags: MTD_WRITEABLE /* force read-only */
},{
name: "Filesystem",
size: (2*1024*1024 - 1024*1280),
offset: MTDPART_OFS_APPEND
},{
name: "Not Used Filesystem",
size: MTDPART_SIZ_FULL,
offset: MTDPART_OFS_APPEND,
mask_flags: MTD_WRITEABLE /* force read-only */
}
};
and I got following as my patitions in kernel boot up messages.
Creating 3 MTD partitions on "Shasta flash":
0x00000000-0x00140000 : "Bootloader/Kernel"
0x00140000-0x00200000 : "Filesystem"
0x00200000-0x02000000 : "Not Used Filesystem"
now I issued
mount /dev/mtdblock/1 /a -t jffs2 which was successful.
How ever I run df I got
# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/root 1787 736 949 44% /
/dev/mtdblock/1 768 768 0 100% /a
i.e there is no room left in this partition though I did not use it at
any time.
# cd /a
# ls -la
drwxr-xr-x 1 0 0 0 Jan 1 00:01 .
drwxr-xr-x 11 0 0 1024 Jan 1 00:01 ..
Where I have gone wrong?
Thanks
Sankalpa
