2.2 Flash Feature

The FLASH feature in ChorusOS 4.0 provides an interface to access memory devices through the Flite 1.2 BSP component. Two commands are available:

• format raw_device

  This command is new to ChorusOS 4.0 and performs a low-level format on the flash device. See the format(1M) man page for more information.

• flashdefrag raw_device [value]

  This command defragments flash memory and exists in ChorusOS 3.2 without the raw_device argument. See the flashdefrag(1M) man page for more information.

The mkdosflashfs and dosfsck commands, which create and check a DOS File system respectively, have been removed. Use the newfs_dos and fsck_dos commands instead. See the newfs_dos(1M) and fsck_dos(1M) man pages for more information.

For more information on the FLASH feature, see the FLASH(5FEA) man page. For more information on formatting a flash memory device, see "How to Format a Flash Memory Device" in ChorusOS 4.0 File System Administration Guide.
