Thanks for the reply. What I have done is included the following code in include/configs/MPC8260ADS.h

#define CFG_FLASH_CFI_DRIVER #define CFG_MAX_FLASH_SECT 35 /* Max # sects per bank */ #define CFG_MAX_FLASH_BANKS 1 /* Max # of flash banks */ #define CFG_FLASH_CFI It's showing some compilation error, saying multiple definition of flash erase, etc. I think it's clashing with the /board/mpc8260ads/flash.c

My questions are: 1) Should I copy the cfi_flash.c to board folder and rename it as flash.c?

or Should I rename the flash.c? Any help in this regard will be highly appreciated.

Thanks and regards, Souvik Maiti

Respected Sir,

Hope this time you won't get any html. Sorry for the inconvenience. Following things I want to make clear:

1. You was correct. Ours is a mpc8260 processor based custom board and we have made our board configuration. In this board, we are using two flash's i) Am29LV160B, each of 2MB size as code flash for storing the linux image. Total constituting a size of 4MB. The base address for code flash is 0xFE800000. ii) Two flash of ST make, total constituting 1MB as boot flash for storing the boot - loader. The base address for boot flash is 0xFE000000.

2. We need the flash driver for the code flash. Since the flash is CFI compliant, I have used the cfi_flash.c as the flash driver.

After defining :

#define CFG_FLASH_CFI_DRIVER #define CFG_MAX_FLASH_SECT 35 /* Max # sects per bank */ #define CFG_MAX_FLASH_BANKS 1 /* Max # of flash banks */ #define CFG_FLASH_CFI #define CFG_FLASH_BASE 0xFE000000 #define CFG_CODE_FLASH 0xFE800000

in board.h and

#ifndef CFG_FLASH_BANKS_LIST #define CFG_FLASH_BANKS_LIST { CFG_CODE_FLASH } #endif

in cfi_flash.c

We are getting the following output:

Stop adding this crap. If necessary, post from another address.

I will not repeat this.
