how to use yaffs under rt-thread.
|
|
|
|
There are three steps.
|
|
1. get yaffs tarball from official repo.
|
|
the repo of official repo is here.
|
|
http://www.aleph1.co.uk/gitweb?p=yaffs2.git;a=summary
|
|
then you should find the 2011-6-28's snapshot, download the tarball
|
|
http://www.aleph1.co.uk/gitweb?p=yaffs2.git;a=snapshot;h=2df51cdb98e799c4d10b4cc7dd7e8858aa79e7d8;sf=tgz
|
|
|
|
decompress the yaffs.tar.gz to rt-thread\components\dfs\filesystems\yaffs2\yaffs
|
|
|
|
2. patch yaffs.diff
|
|
open an terminal.
|
|
(1) on windows
|
|
open cmd command prompt, then use [cd] command to come current path
|
|
for example
|
|
F:\Project\svn\rt-thread\components\dfs\filesystems\yaffs2>
|
|
then type command
|
|
patch -p1 < yaffs.diff
|
|
you will get some log information as followings
|
|
F:\Project\svn\rt-thread\components\dfs\filesystems\yaffs2>patch -p1 < yaffs.diff
|
|
patching file `dfs_yaffs2.c'
|
|
patching file `yaffs/direct/yaffs_list.h'
|
|
patching file `yaffs/direct/yaffs_nandif.c'
|
|
patching file `yaffs/direct/ydirectenv.h'
|
|
patching file `yaffs/direct/yportenv.h'
|
|
patching file `yaffs_nandcfg.c'
|
|
patching file `yaffs_osglue.c'
|
|
|
|
now you can delete yaffs.diff
|
|
|
|
(2) on linux
|
|
Help yourself. Since you have use linux as your os, I believe in you.
|
|
|
|
3.add nand driver and compile
|
|
In order to use yaffs, you should provide a nand driver which is needed
|
|
by yaffs. There is an example file in rt-thread\components\dfs\filesystems\uffs\nand.
|
|
you should modify yaffs_nandcfg.c according to your nand driver.
|
|
then you can use scons or IDE like MDK or IAR to compile.
|
|
|
|
enjoy !
