Just a question... Do you really NEED 64 kB or even 128 kB environement size? In my experience, 16 kB is almost always more than sufficient. Keep in mind that the environment
size can
be smaller than the sector size which stores the environment, and that a big enviroment size adds to the boot delay, as the whole environment size needs 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 boot up even though I do saveenv Hence I kept it equal to sector size This may be a bug...??
Hi Wolfgang This was really a bug in my spi driver, I fixed it, now it's working for any size (even 4k) Thanks for pointing this issue, I am using CONFIG_ENV_SIZE = 4k now
