JFFS2 NAND support:
|
|
|
|
To enable, use the following #define in the board configuration file:
|
|
|
|
#define CONFIG_JFFS2_NAND 1
|
|
|
|
Configuration of partitions is similar to how this is done in U-Boot
|
|
for JFFS2 on top NOR flash. If a single partition is used, it can be
|
|
configured using the following #defines in the configuration file:
|
|
|
|
#define CONFIG_JFFS2_NAND_DEV 0 /* nand device jffs2 lives on */
|
|
#define CONFIG_JFFS2_NAND_OFF 0 /* start of jffs2 partition */
|
|
#define CONFIG_JFFS2_NAND_SIZE 2*1024*1024 /* size of jffs2 partition */
|
|
|
|
If more than a single partition is desired, the user can define a
|
|
CONFIG_SYS_JFFS_CUSTOM_PART macro and implement a
|
|
|
|
struct part_info* jffs2_part_info(int part_num)
|
|
|
|
function in a board-specific module. An example of such function is
|
|
available in common/cmd_jffs2.c
|
|
|
|
The default configuration for the DAVE board has a single JFFS2
|
|
partition of 2 MB size.
