Hello Yaffs ers and Charles
=0D
I want to report an observation I had when testing Yaffs2 direct
interface. In yaffs2 we have the option of "useHeaderFileSize".
Now in yaffs_Scan() , after we scan all blocks, we check if "yaffs2"
option is enabled or not.
=0D
If yaffs2 is enabled we make dev->useHeaderFileSize =3D 1. Upon enabling
this, the expected result would be , that object=0D
would get the file size from object header, and not from scanned file
size.
=0D
Now when we do dumpDir(const char* path), my observation was that , it
shows all the files , but sizes are shown as 0.
=0D
At this point , I tried to make dev->useHeaderFileSize =3D 0. So now , we
directly assign the object's scanned file size=0D
to object's file size and VOILA!!! Everything seems to work fine. This
time dumpDir(const char* path) returns all the files=0D
with there respective sizes!!!
=0D
Please let me know if you have encountered any such issues!=0D
=0D
Thanks
