Hi,
In TC3xx usermanual, it's said that all-0 and all-1 will be read with ECC errors. Does it mean a const array with 8 bytes consecutive 0xFF can't be read witout ECC error?
Best regards

Hi Jamber,
After erased Flash, you will get all-0, as a side effect, read will be with ECC errors.
If normal program Flash with all-1, it should be no ECC error.

No, the trick is in the word "over-programming" this means that if you have some data , and you over-program it with all-1's without erasing it first, this would cause an ECC error.

Hi, ugo_8a
Thank you, could you tell me what all-0 is?
And as usermanual said, by reading erased or over-programmed area causing ECC error is just an "side effect", so if reading a const array with 8 bytes consecutive 0xFF is not all-1 case, what's the really case of all-1, and all-0?
Best regards
