Hi Rajath,

It looks like you have modified the proper section to support reading the nandflash's chip ID. A few questions.

Is the NAND still on chip select 0?
Is the bus size the same as the reference design?
Can you verify the manufacturer id and chip id?
Finally can you send the modification you made to bsp_cfg?

Regards,

Thanks for the reply,

Is the NAND still on chip select 0 - Yes.

Is the bus size the same as the reference design - 8 bit

Can you verify the manufacturer id and chip id - as mentioned in the datasheet.

changes made to bspcfg.c

for 8GB,

               0x98,  //manufacturerId 2C
               0xDE,  //deviceId CA
               4124,//number of blocks
               256, //Sectors/pages per block
               8192, //page size, (8224 - redundant bytes = 8192), multiple of 1024 taken
               4  //Word data

changes made in bsp_def.h

#define M_NAND_GPMC_CONFIG1 0x00000800  
#define M_NAND_GPMC_CONFIG2 0x00040400
#define M_NAND_GPMC_CONFIG3 0x00040301
#define M_NAND_GPMC_CONFIG4 0x03010501
#define M_NAND_GPMC_CONFIG5 0x00050707
#define M_NAND_GPMC_CONFIG6 0x16000f80
#define M_NAND_GPMC_CONFIG7 0x00000008

Hope i get a reply ASAP.

1) Do i need to make changes in bsp_def.h config registers

Hi Rajath,

The 2.30 BSP NAND driver currently does not support 8-bit access.  You will need to update the driver to switch the access from 16-bit to 8-bit.  Please see the following thread for more details.

Thanks for the reply,

The thread to which you pointed is pretty much helpful but still even Andreas is at the same page where i am.

Could you be more lucid so that i can get this problem resolved.

I am newbie to this,kindly help me out in fixing this issue.
