Just a question... Do you really NEED 64 kB or even =20 128 kB environement size? In my experience, 16 kB is almost=20 always more than sufficient. Keep in mind that the=20 environment size can be smaller than the sector size which=20 stores the environment, and that a big enviroment size=20 adds to the boot delay, as the whole environment size needs=20 to be CRC32 checked.
I agree, even 4kb is sufficient for me but if I keep it less than a sector size it gives me bad CRC warning at boo= t up even though I do saveenv Hence I kept it equal to sector size This may be a bug...??
This is indeed a bug, then. To give you an example - in "include/configs/TQM5200.h" we have:
#define CONFIG_ENV_SIZE 0x4000 /* 16 k - keep small for fast booting */ ... #define CONFIG_ENV_SECT_SIZE 0x40000
This works fine - CRC computation covers only the 16 k as set in CONFIG_ENV_SIZE.
It seems you really have a bug there, which should be fixed.
Best regards,
Wolfgang Denk
