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...

 

 

Best Regards
