The blocks do not have to&nbsp; follow each other, so a space between blocks is acceptable. It is required that the blocks do not intersect and that they are listed in ascending order in the array by their starting address. Yes , it can have a gap, you can have a try.</P><P></P><P>Have a nice day!</P><P></P><P>Regards</P><P>Daniel</P></BODY></HTML> Mon, 18 Jul 2016 06:31:14 GMT https://community.nxp.com/t5/MQX-Software-Solutions/Flashx-File-system/m-p/573584#M16562 danielchen 2016-07-18T06:31:14Z
