Hi Oaksys,


I do not understand your write and read operation sequences from your provided examples.

Would like to know if the data error only happened on a specific address only or there is an inconsistency in the write/read process?

For example, everytime you write something, does the written data valid after read?

Or there is data error on specific location whereby the data doesnot change after write which is the 0xF that you noticed?

Make sure to perform erased first before a write and see if any difference.


Thanks.

Regards,
