I.mx233 Nand boot failure

[kpoo...@gmail.com]

Hi All,
We need to bring up 1GB NAND on our custom imx233 board based on WINCE 6.0.
But we are getting ROM error code 0x80501003 ( The file signature or file version is incorrect)

Please can anyone help to solve this issue ...

Following is our NAND configuration:

1 Page = 4K +224 bytes
pages per block = 128
No of blocks = 2048
No of planes = 2

Code chages done for this NAND:

1. Modified Nandtypes.h to include new NAND geometry

2. \soc\mx233_fsl_v2_pdk1_8\inc\mx233_nandlayout.h

#define CHIP_BCB_SECTOR_STRIDE (64)
#define CHIP_BCB_BLOCK_LIMIT (2)

3. iMX233-EVK-PDK1_8\SRC\BOOTLOADER\COMMON\nand.c

NandWriteNCB()
{
m_u32DataPageSize = 4096; //(1 GB change)
m_u32TotalPageSize = 4096 + 224;
m_u32SectorsPerBlock = 2 * pFlashInfo->fi.wSectorsPerBlock; // as per imx233 reference manual

m_u32SectorInPageMask =2;
m_u32SectorToPageShift =1;
m_u32TotalInternalDie = 1;
m_u32InternalPlanesPerDie = 2;
NCB.NCB_Block2.m_u32ECCType = BCH_Ecc_6bit;
NCB.NCB_Block2.m_u32EccBlock0EccLevel = BCH_Ecc_6bit;
NCB.NCB_Block2.m_u32EccBlock0Size = 0; //!< Number of bytes for Block0 - BCH
NCB.NCB_Block2.m_u32EccBlockNSize = 512; //!< Block size in bytes for all blocks other than Block0 - BCH
NCB.NCB_Block2.m_u32NumEccBlocksPerPage = 8;
}

4. No of row address is 3 cycles and column address is 2 cycles

Are these changes correct?

Attached NAND datasheet for reference
