This makes sense as one should *not* copy from one sector in a flash to the same sector in a flash. Flash is erased in sectors, usually 128K and should be treated as a complete sector.
The cp command is usually used to copy from RAM to FLASH or from FLASH to RAM. What you are doing seems illogical.
