    Hi feng lin,

    Did you solve your recognition problem? How did you do? I have a similar problem with a same family's memory (MT29F2G08) than yours. I hope your answer!

    Thanks in advance

    Hi oscar，

    I had solve the problem. The default for OMAPL138 EVM  is to check nor or nand flash,

    in file arch/arm/mach-davinci/board-da850-evm.c, it will execute the function of da850_evm_setup_nor_nand().

    What you must to do is annotation the  function da850_evm_setup_nor_nand() ,and add the function for your nandflash init in da850_evm_init.

    Just like

    ...

    static inline int nand(void)
    {
        platform_add_devices(da850_evm_devices,
                                    ARRAY_SIZE(da850_evm_devices));
        return 0;
    }

    ...

    static __init void da850_evm_init(void)

    {

     ..........

    //da850_evm_setup_nor_nand();

    nand();

    }

    I

     

     

    Hope my solution can help you!
