CONFIG_JFFS2_FS_NAND: JFFS2 support for NAND flash

General informations

The Linux kernel configuration item CONFIG_JFFS2_FS_NAND has multiple definitions:

JFFS2 support for NAND flash found in fs/Kconfig

The configuration item CONFIG_JFFS2_FS_NAND:

• prompt: JFFS2 support for NAND flash
• type: bool
• depends on: CONFIG_JFFS2_FS
• defined in fs/Kconfig
• found in Linux kernels: 2.6.8–2.6.12

Help text

This enables the support for NAND flash in JFFS2. NAND is a newer type of flash chip design than the traditional NOR flash, with higher density but a handful of characteristics which make it more interesting for the file system to use.

Say 'N' unless you have NAND flash.

JFFS2 support for NAND flash (EXPERIMENTAL) found in fs/Kconfig

The configuration item CONFIG_JFFS2_FS_NAND:

• prompt: JFFS2 support for NAND flash (EXPERIMENTAL)
• type: bool
• depends on: CONFIG_JFFS2_FS && CONFIG_EXPERIMENTAL
• defined in fs/Kconfig
• found in Linux kernels: 2.5.45–2.5.75, 2.6.0–2.6.7

This enables the experimental support for NAND flash in JFFS2. NAND is a newer type of flash chip design than the traditional NOR flash, with higher density but a handful of characteristics which make it more interesting for the file system to use. Support for NAND flash is not yet complete and may corrupt data. For further information, including a link to the mailing list where details of the remaining work to be completed for NAND flash support can be found, see the JFFS2 web site at http://sources.redhat.com/jffs2.

Say 'N' unless you have NAND flash and you are willing to test and develop JFFS2 support for it.
