As the addr is not a pointer adding a size of the buffer in words calculates a wrong offset in flash (+8 instead of +32). This eventually leads to the loop overstepping the boundary of the sysparam area and include the beginning of the esp system parameters sector - the last read from 0x003fafe8 to 0x003fb007 with a 4M flash. The latter is not empty, so the sysparam area checker would always see the sysparam area as not empty.
