Hi,
I'm trying to use YAFFS2 for my root file system.
I have flashed a NAND FLASH partition with YAFFS2 rootfs image and I could boot from this partition.
Here are commands:
flash_eraseall /dev/mtd2
nandwrite -a -o /dev/mtd2 ./rootfs.yaffs2
Now, after booting using YAFFS2, when I paly around, I get YAFFS BUG print on the console,
Especially when I try to execute,
- rm some_soft_link_file
- rm some_dir/ -rf
even though actually files are removed
,
YAFFS prints bug prints as:
==>> yaffs bug: fs/yaffs2/yaffs_guts.c 6836
==>> yaffs bug: fs/yaffs2/yaffs_guts.c 6763
==>> yaffs bug: fs/yaffs2/yaffs_guts.c 6763
-
rm a_simple_file
doesn't print any bug.
-----Here is the snippet of the code I'm using (latest one downloaded from yaffs website). The BUG locations are in BOLD ----
static void yaffs_AddObjectToDirectory(yaffs_Object * directory,
yaffs_Object * obj)
{
if (!directory) {
T(YAFFS_TRACE_ALWAYS,
(TSTR
("tragedy: Trying to add an object to a null pointer directory"
TENDSTR)));
YBUG();
}
if (directory->variantType != YAFFS_OBJECT_TYPE_DIRECTORY) {
T(YAFFS_TRACE_ALWAYS,
(TSTR
("tragedy: Trying to add an object to a non-directory"
TENDSTR)));
YBUG();
}
if (obj->siblings.prev == NULL) {
/* Not initialised */
YBUG();
} else if (ylist_empty(&obj->siblings)) {
YBUG();// line number 6836
}
yaffs_VerifyDirectory(directory);
yaffs_RemoveObjectFromDirectory(obj);
/* Now add it */
ylist_add(&obj->siblings, &directory->variant.directoryVariant.children);
obj->parent = directory;
if (directory == obj->myDev->unlinkedDir
|| directory == obj->myDev->deletedDir) {
obj->unlinked = 1;
obj->myDev->nUnlinkedFiles++;
obj->renameAllowed = 0;
}
yaffs_VerifyDirectory(directory);
yaffs_VerifyObjectInDirectory(obj);
}

static void yaffs_VerifyDirectory(yaffs_Object *directory)
{
struct ylist_head *lh;
yaffs_Object *listObj;
if(!directory)
YBUG();//line number 6763
if(yaffs_SkipFullVerification(directory->myDev))
return;
if(directory->variantType != YAFFS_OBJECT_TYPE_DIRECTORY){
T(YAFFS_TRACE_ALWAYS, (TSTR("Directory has wrong type: %d" TENDSTR),directory->variantType));
YBUG();
}
/* Iterate through the objects in each hash entry */
ylist_for_each(lh, &directory->variant.directoryVariant.children) {
if (lh) {
listObj = ylist_entry(lh, yaffs_Object, siblings);
if(listObj->parent != directory){
T(YAFFS_TRACE_ALWAYS, (TSTR("Object in directory list has wrong parent %p" TENDSTR),listObj->parent));
YBUG();
}
yaffs_VerifyObjectInDirectory(listObj);
}
}
}
How could this be solved. Waiting for your Help!!

Hari
