    CX3, Accessing Un-allocated space in a SPI flash memory


      Hi sir,



      I am using a flash memory PN named ST M25P40, it has 512K Bytes size.


      a custom cypress cx3 firmware being used currently has around 200K Bytes size, so, the SPI memory should have 300K Bytes free space.


      • First question

                Is it OK recording some data into this "not used" 300K Bytes space?

      • Second question,

           How to program data into those un-used space?



      Thank you
