Hi,
i have a strange problem with the saveenv command, or maybe with my
config :)
After booting a fresh compiled u-boot with the default environment i
can save the env without any problems. U-boot unprotect, erase and
write the flash. but after add a new env-variable, e.g. bootargs,
saveenv will unprotect the flash, erase the flash but then u-boot will
not write the flash because the "Flash not Erased" error.
Is there a different in addressing the env during boot-time, or read
and write ?
#define CONFIG_ENV_IS_IN_FLASH 1
#define CONFIG_ENV_SIZE 0x2000 // a 8k sector at
the beginning of the flash
#define CONFIG_ENV_SECT_SIZE 0x2000
#define CONFIG_SYS_ENV_OFFSET 0x0000
#define CONFIG_ENV_ADDR
(CONFIG_SYS_FLASH_BASE+CONFIG_SYS_ENV_OFFSET)
TEXT_BASE = 0xFFC00000
CONFIG_SYS_FLASH_BASE = 0xFFC0000
Thanks
Georg
