How measure NAND consumption by kernel

Hi,


I am trying to find out how much NAND space kernel and my application
consumes.
Does anyone know how can check that?
I tried "cat mtd" but it displays only block sizes.

thank you.

Mount the NAND based filesystem and simply run the "df" command.

But for flash filesystems the number you get is very inexact, because these
kind of filesystems are using compression to store the data into the flash
memory. At the end it means you can handle a 20 MiB root filesystem in your
16 MiB NAND flash device (just for example, compression vary with the data
you store)

Thanks Juergen.
