Describe the bug
It seems that there is implicit padding being added by the compiler in FM_MonitorReportEntry_t & FM_ChildQueueEntry_t.

Code snips

FM/fsw/inc/fm_msg.h

Lines 512 to 518 in e7afedc

	typedef struct
	{
	uint8 ReportType;
	char Name[OS_MAX_PATH_LEN]; /**< \brief File system name */
	uint64 Blocks; /**< \brief Block count from last check/poll, 0 if unknown */
	uint64 Bytes; /**< \brief Byte count from last check/poll, 0 if unknown */
	} FM_MonitorReportEntry_t;

FM/fsw/inc/fm_msg.h

Lines 656 to 669 in e7afedc

	typedef struct
	{
	CFE_MSG_FcnCode_t CommandCode; /**< \brief Command code - identifies the command */
	uint32 DirListOffset; /**< \brief Starting entry for dir list commands */
	uint32 FileInfoState; /**< \brief File info state */
	uint32 FileInfoSize; /**< \brief File info size */
	uint32 FileInfoTime; /**< \brief File info time */
	uint32 FileInfoCRC; /**< \brief File info CRC method */
	char Source1[OS_MAX_PATH_LEN]; /**< \brief First source file or directory name command argument */
	char Source2[OS_MAX_PATH_LEN]; /**< \brief Second source filename command argument */
	char Target[OS_MAX_PATH_LEN]; /**< \brief Target filename command argument */
	uint8 GetSizeTimeMode; /**< \brief Whether to invoke stat call for size and time (CPU intensive) */
	uint32 Mode; /**< \brief File Mode */
	} FM_ChildQueueEntry_t;

Expected behavior
Make implicit padding explicit.
