How can I create my own defined MTD device through kernel command line on ARM system?

Question

At first, I didn't add any kernel parameter and then got MTD device

/proc/mtd:
dev:    size   erasesize  name
mtd0: 01000000 00010000 "spi1.0"

then, I added setenv mtdids "mtdids=spi1.0", and setenv mtdparts "mtdparts=spi1.0:2m(U-Boot)ro,-(RootFS)ro" to kernel command line, at the meantime, I turned on

"Command line partition table parsing",
"ARM Firmware Suite partition parsing"

of Device Drivers ---> Memory Technology Device (MTD) support through Kconfig. Finally, I got,

 dev:    size   erasesize  name
 mtd0: 00100000 00010000 "u-boot"
 mtd1: 00400000 00010000 "kernel"
 mtd2: 00a00000 00010000 "rootfs"

But this is still not what I want. Do I have something missing? Thanks for help,

Answer 1

you can work with it but after creating the partitions you must create an ubifs file system for the each partitions, then only the board will work with the MTD.
