MT29F8G08ABABA NAND support for AM335x ANDROID

Hello 

        I'm using MT29F8G08ABABA NAND device. IC characteristics are,

– Page size x8: 4,320 bytes (4,096 + 224 bytes)
– Block size: 128 pages (512K + 28K bytes)
– Plane size: 2 planes x 1,024 blocks per plane
– Device size: 8Gb: 2,048 blocks

My u-boot boot log is

NAND: HW ECC Hamming Code selected
nand_get_flash_type: unknown NAND device: Manufacturer ID: 0x2c, Chip ID: 0x38
No NAND device found!!!
0 MiB
MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1

          What are the changes i've to do in nand_ids.c , nand_base.c etc,,. make this chip work fine. 

Thanks in advance.

    Hi,

    You should add something like:

    {"NAND 1GiB 3,3V Micron 8-bit", 0x38, 0, 1024, 0, LP_OPTIONS},

    to nand_ids.c.

    Before adding anything, please check if CONFIG_SYS_NAND_ONFI_DETECTION is enabled?

    Check what does the nand_flash_detect_onfi() function return?

    The "No NAND device found!!!" print shows that nand_get_flash_type() function returns an error. Check why and what the error number is, then post it here.

    Best regards,
    Miroslav

    Hi Miroslav,

    I am using MT29F8G08ABABA flash with AM335x EVM. i have customized with our own with AM335x platform without cpld section.

    I tried to done some changes under u-boot for detecting the NAND, but it is not recognized and the below error got from log.

    U-Boot 2013.01.01 (Feb 03 2015 - 17:46:50)

    I2C:   ready

    DRAM:  512 MiB

    WARNING: Caches not enabled

    Incorrect magic number (0xffffffff) in EEPROM

    Could not get board ID #01

    NAND:  No NAND device found!!!

    0 MiB

    MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1

    *** Warning - readenv() failed, using default environment

    Using versions:

    SDK5 - u-Boot

    SDK5 - Linux 3.2

    Please suggest what are the changes required to modify under u-boot & kernel.

    Thanks
