EMIF 16 bit NOR Flash booting

Hi

We have designed a board with C6678 which is connected to EMIF 16 bit 128MB Nor flash and used I2c EEPROM ( eeprom is same as EVM kit)

We Flashed IBL into EEPROM .We wrote a driver for our nor flash and we could able to access nor flash successfully from 6678.We Flashed Linux
BBLOB Image into the NOR FLASH.  Tested DDR and it is working fine.

We put some debug messages in ibl in norboot/norboot.c to compare whether flash data contents is equal to the content of branch address 0x80000000 and whether entry address is 0x80000000

After poweron the board, IBL is up, comparision of data also ok and entry address is 0x80000000.But, Linux Image is not up. We even tested with simple application flashed into nor.That is also not getting executed.

Can you Please shed some light on this issue why the code is not executed form 0x80000000 after copied from EMIF nor flash?


Thanks
