Hi,
I'm trying to get a 64 MByte nand flash to be partitioned in a 32MB cramfs
and 32MB jffs2 partition. In case anyone's curious, I would like the
cramfs to be root as it would be a faster mount and its read-only feature.
I tried to do this in the kernel by
static struct mtd_partition partition_info[] = {
[0] = {
.name = "CRAM",
.offset = 0,
.size = 32 * 1024 * 1024,
.mask_flags = MTD_WRITEABLE, /* force read-only */
},
[1] = {
.name = "JFFS2",
.offset = 32 * 1024 * 1024,
.size = MTDPART_SIZ_FULL,
}
};
but when I cat/proc/mtd, I get
/ # cat /proc/mtd
dev: size erasesize name
mtd0: 04000000 00004000 "rootfs"
so I realise that this is affected by the bootargs passed by u-bootloader
which is
"bootargs=console=ttyS0 mtdparts=a9m9750:0x4000000@0(rootfs)
root=mtdblock/0 rootfstype=jffs2"
How should I passed the bootargs?
Thanks in advance,
Terence.
