To use JFFS2 define CONFIG_CMD_JFFS2. - -The module adds three new commands. -fsload - load binary file from a file system image -fsinfo - print information about file systems -ls - list files in a directory -chpart - change active partition - -If you do now need the commands, you can enable the filesystem separately -with CONFIG_FS_JFFS2 and call the jffs2 functions yourself. - -If you boot from a partition which is mounted writable, and you -update your boot environment by replacing single files on that -partition, you should also define CONFIG_SYS_JFFS2_SORT_FRAGMENTS. Scanning -the JFFS2 filesystem takes *much* longer with this feature, though. -Sorting is done while inserting into the fragment list, which is -more or less a bubble sort. That algorithm is known to be O(n^2), -thus you should really consider if you can avoid it! - ---- - -TODO. - - Remove the assumption that JFFS can dereference a pointer - into the disk. The current code do not work with memory holes - or hardware with a sliding window (PCMCIA). |
