    Hi LPD,
    I need a bit information about the flash chip used by you in LH79520 Card Engine. I'm trying to use jffs2 and I need to know which driver (if already done) is available. Anyone tried to use jffs2 before in this hardware ?
    Any help will be welcome,
    thanks in advanced.

    Miguel,

    You're going to want to reference the LH79520 card engine BOM for specific information for card engine flash. Once you have the manufacturer and a part number you'll be able to get datasheets and user's guide for the flash that is specific to your card engine. The BOM for the LH79520 can be found at the following link:

    Hello all

    I added to "linux/arch/arm/config.in"

    define_bool CONFIG_MTD y
    define_bool CONFIG_MTD_PARTITIONS y
    define_bool CONFIG_MTD_CHAR y
    define_bool CONFIG_MTD_BLOCK y
    define_bool CONFIG_MTD_CFI y
    define_bool CONFIG_MTD_CFI_INTELEXT y

    and rebuild kernel
    when I download and boot vmlinux,I can't find any info about MTD
    but on the target, cat /proc/devices,I can find device
    90 mtd
    31 mtdblock
    *************************
    Is it neccssary to add some other paras to it?
    and there are many files under /maps that define the partitions, I'm still not sure which one is being used?
