  1. JFFS

    Hi,
    I have a linux-based device with JFFS2, and I need to know as to configure
    the system.
    Some time the system employs much time in order to boot and I don't have
    idea of because.
    This is an extract of my log file.

    NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
    fatfs: bogus cluster size
    split old frag 0x22000-0x47000 -->hole
    split old frag 0x0000-0xeb000 -->hole
    split old frag 0x0000-0x32000 -->hole
    split old frag 0x0000-0x5b000 -->hole
    split old frag 0x37000-0x5b000 -->hole
    split old frag 0x0000-0x36000 -->hole
    split old frag 0x3f000-0x5b000 -->hole
    split old frag 0x37000-0x3c000 -->hole

    It is possible to force the reorder manually?
    Thanks in advance.

    Stefano.

    Hi Stefano,
    which system ?
    When this happen ?
    Could you post a more detailed log ?

    Please consider that the first time a JFFS2 partition boot on a Linux
    system may take many time to scan sectors. Starting from te seconf time
    it will boot faster.

    Ciao

    Kernel's version is 2.4.4
    It succeeded more often at the boot of the system.
    What log do you need?
    Thanks.
