This structure describes an individual flash region. An array of these structures make up the flash region table located in the flash layout sector.

Syntax


typedef struct _FlashRegion {
  REGION_TYPE regionType;
  DWORD dwStartPhysBlock;
  DWORD dwNumPhysBlocks;
  DWORD dwNumLogicalBlocks;
  DWORD dwSectorsPerBlock;
  DWORD dwBytesPerBlock;
  DWORD dwCompactBlocks;
} FlashRegion, *PFlashRegion;

Members

regionType: Type of region, which must be one of the following: XIP, READONLY_FILESYS, or FILESYS.

dwStartPhysBlock: Starting physical block of the region. Set to zero (0) if not used.

dwNumPhysBlocks: Number of physical blocks in the region. Set to zero (0) if not used.

dwNumLogicalBlocks: Number of logical blocks in the region. Set to zero (0) if not used. Set to -1 to indicate that the region extends to the end of flash memory.

dwSectorsPerBlock: Number of sectors in a flash block.

dwBytesPerBlock: Number of bytes in a flash block.

dwCompactBlocks: Number of blocks reserved for compaction by the FAL.

Remarks

Either the dwStartPhysBlock and dwNumPhysBlocks members or the dwNumLogicalBlocks member must be specified.
