Linux/OMAP-L138: Linux/OMAP-L138: How to flash Linux kernel into NAND-Flash partition from Linux

Part Number:OMAP-L138

Tool/software: Linux

I have to update (write) a new Linux kernel into NAND-Flash partition from a running Linux system.

To write into partition 2 of NAND-Flash I use the program "nandwrite" with option "-p":

nandwrite /dev/mtd -p <Image>

But after that my board does not start up; the bootloader "u-boot" the bootloader complains about CRC error loading the kernel.

I'm using the "4 Bit HW ECC correction" for the NAND-Flash in the bootloader and in the Linux kernel.

For bootloader "u-boot" there are defined:

#undef CONFIG_SYS_NAND_HW_ECC
#define CONFIG_SYS_NAND_4BIT_HW_ECC_OOBFIRST
#define CONFIG_SYS_NAND_USE_FLASH_BBT

For Linux kernel (in board specific file) there are defined:

static struct davinci_aemif_timing gins_qmonixx_nand_timing = {
    // All timings in nanoseconds
    .wsetup = 10,
    .wstrobe = 20,
    .whold = 0,
    .rsetup = 10,
    .rstrobe = 20,
    .rhold = 20, // For reliable 16-bit NAND operations R_HOLD must be set to 1 to ensure 2 clock cycles for ECC calculation
    .ta = 60,
};

static struct davinci_nand_pdata gins_qmonixx_nand_pdata = {
    .parts = gins_qmonixx_nand_parts,
    .nr_parts = ARRAY_SIZE(gins_qmonixx_nand_parts),
    .options = NAND_BUSWIDTH_16,
    .timing = &gins_qmonixx_nand_timing,
    
    // Configuration for ECC
    // See also configuration for U-Boot: CONFIG_SYS_NAND_4BIT_HW_ECC_OOBFIRST, CONFIG_SYS_NAND_USE_FLASH_BBT
    .ecc_mode = NAND_ECC_HW,    // do not use NAND_ECC_HW_OOB_FIRST here!
    .ecc_bits = 4,
    .bbt_options = NAND_BBT_USE_FLASH,
};

What could be the problem?

Remark:
If I write the Linux kernel with help of the bootloader "u-boot" into the NAND flash, then the system is started successfully!

Thanks for your help in advance!
