FLASH_REGION_INFO_FLAGS (Windows Embedded CE 6.0)

1/6/2010

This enumeration defines flags that describe the features supported by a flash part.

Syntax

enum FLASH_REGION_INFO_FLAGS {
  FLASH_FLAG_NAND                     = 0x00000001,
  FLASH_FLAG_NOR                      = 0x00000002,
  FLASH_FLAG_REQUIRE_SEQ_PAGE_PROGRAM = 0x00000004,
  FLASH_FLAG_SUPPORTS_COPY            = 0x00000008,
  FLASH_FLAG_SUPPORTS_XIP             = 0x00000010,
  FLASH_FLAG_SUPPORTS_LOCKING         = 0x00000020,
};

Elements

• FLASH_FLAG_NAND
  Indicates that the flash part is NAND.

• FLASH_FLAG_NOR
  Indicates that the flash part is NOR.

• FLASH_FLAG_REQUIRE_SEQ_PAGE_PROGRAM
  Indicates that a region requires sequential page programming and does not allow out-of-order sector writes within a block. For example, multi-level cell (MLC) NAND.

• FLASH_FLAG_SUPPORTS_COPY
  Indicates that the flash media driver platform-dependent driver (PDD) implements IOCTL_FLASH_PDD_COPY_PHYSICAL_SECTORS.

• FLASH_FLAG_SUPORTS_XIP
  Indicates that the flash part supports XIP. The PDD must implement IOCTL_FLASH_PDD_GET_PHYSICAL_SECTOR_ADDRESS for XIP support.

• FLASH_FLAG_SUPPORTS_LOCKING
  Indicates that the flash part supports block level locking and unlocking. The PDD must implement IOCTL_FLASH_PDD_LOCK_BLOCKS for block locking and unlocking support.
