How to make jffs2

[mgrunt]

Hi all, i install to my mini2440 (128MB NAND) u-boot, and kernel. Both works OK. Now i must make root filesystem. It's possible make from file directory structure (/bin, /usr etc.) JFFS2 file? Probebly yes, with make.jffs2 program. But program have several parameters, and i don't know, which values i must set for NAND 128MB. Can you enybody help me?

Thank you

Hi Michal,

Try to use buildroot. It is an extremely useful stuff.
Untar it and execute 'make menuconfig'. Change next parameters:

Code: Select all

Target Architecture
    [*] arm

Target Architecture Variant
    [*] arm920t

Target ABI: 
    [*] EABI

Toolchain
    [*] Enable RPC // need for NFS support in busybox
    [*] Use software floating point // need for for busybox 
    [*] Build/install c++ compiler and libstdc++? // need for QT compiling

Package Selection for the target 
    [*] <choose software you want to use in your system>

Target filesystem options
    [ ] ext2
    [*] jffs2

        Flash Type
            (x) NAND flash with 2kB Page and 128 kB erasesize

Save these settings and execute 'make'. You'll find ready to flash rootfs.arm.jffs2 rootfs image in ./binaries/uclibc/ folder. Buildroot will download and build all necessary packages (toolchain, binutils, uclibc, busybox etc.)
Enjoy.
