[U-Boot-Users] Help: flash driver for CFI complient flash

[s.maiti at tcs.com]

Hi all,

I am using a flash of AMD make (Am29LV160B) in our custom board which is 
based on mpc8260ads board. This flash is CFI complient. So I want to use 
the cfi_flash.c as a driver for the flash. Can anyone tell me the 
procedure ie. what need to be done to use the driver?

Please help.

Thanks and regards,

Select it in your board confg file... Fell free to compare  with  the
configurationof other boards. grep is your friend.

[U-Boot-Users] Help: flash driver for CFI complient flash

[s.maiti at tcs.com]

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

Yes. You must use exactly one flash driver only.

> My questions are:

No.

>     Should I rename the flash.c?

No. Decide which driver to  use  (cfi_flash  recommended)  and  don;t
configure  the  oither  one  (i. e. edit board/<name>/Makefile not to
build board/<name>/flash.o if you don;t use it).

Ummm... is your board *really* a MPC8260ADS board?

If yes, why are you making  these  changes  -  the  board  should  be
working as is.

If not, why are you meddling with this file  then?  Create  your  own
board configuration, please!

[U-Boot-Users] Help: flash driver for CFI complient flash

[s.maiti at tcs.com]

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:

I have the same problem and the same output!

Is it right when I add this to my board.h:

*/
#define CFG_FLASH_WRITE_TOUT    500     /* Timeout for Flash Write (in ms)
