[U-Boot-Users] help:error occured when 'saveenv'

[xbc_5419]

hi,

i have been trying to port the u-boot 1.2.0 to my board which based on the at91rm9200.

when running the 'saveenv' ,it promted out 

       "Saving Environment to Flash...
        Error: start address not on sector boundary"

my flash is MT-28F128J3, which has 128 128KB(x16bit) erase blocks,in the include/configs/myboard.h  i defined the 
       #define PHYS_FLASH_1   0x10000000
       #define PHYS_FLASH_SIZE   0x1000000  /* 16 megs main flash */
       #define CFG_FLASH_BASE   PHYS_FLASH_1
       #define CFG_MAX_FLASH_BANKS  1
       #define CFG_MAX_FLASH_SECT  128

       #define CFG_ENV_IS_IN_FLASH  1
       #ifdef CONFIG_SKIP_LOWLEVEL_INIT
       #define CFG_ENV_ADDR   (PHYS_FLASH_1 + 0x60000)  /* after u-boot.bin */
       #define CFG_ENV_SIZE   0x10000 /* sectors are 64K here */
       #else
       #define CFG_ENV_ADDR   (PHYS_FLASH_1 + 0xe000)  /* between boot.bin and u-boot.bin.gz */
       #define CFG_ENV_SIZE   0x2000  /* 0x8000 */
       #endif /* CONFIG_SKIP_LOWLEVEL_INIT */

what can i do to fix it ...??
Any help will be appreciated....thanks you...

  This seems ok, as the above address is on the sector boundary
  (multiple of 128k).

  This seems to be the problem area. Change the offset 0xe000
  so that the address is a multiple of 128k.

Hi Jack Xu,

When we want to write any data on to an address location of the flash
device,this address location should match with 
any sector starting address.

In your case,the flash address where you want the environment variables to
be copied,  does not seem to 
be the beginning address of any flash sector .

Verifying the address value where you want to write with the sector start
addresses  , might solve your problem.

Regards,
Verma.
