wdenk998eaae2004-04-18 19:43:36 +00009configured using the following #defines in the configuration file:
10
11#define CONFIG_JFFS2_NAND_DEV 0 /* nand device jffs2 lives on */
12#define CONFIG_JFFS2_NAND_OFF 0 /* start of jffs2 partition */
13#define CONFIG_JFFS2_NAND_SIZE 2*1024*1024 /* size of jffs2 partition */

15If more than a single partition is desired, the user can define a

20function in a board-specific module. An example of such function is

23The default configuration for the DAVE board has a single JFFS2
24partition of 2 MB size.
