Hi
    Your action is so quickly! I have recieved your mail yesterday, and try 
it, and have a same problem as you said. But I'm a new bie, maybe I can do 
nothing for you. I just be very happy to receive first mail from this mail 
list since 2 week ago.
    I will read the source code this weekend, I hope i can do something for 
us. Good Lucky!


    I have found some problem before:


********************************
    When i first put the yaffs in my uClinux-dist-20030909, I found something 
error in the defining of yaffsObjectHeader


typedef struct
{
yaffs_ObjectType type;

int parentObjectId;
__u16 sum__NoLongerUsed;
char name[YAFFS_MAX_NAME_LENGTH + 1];

__u32 st_mode;
...

    Because of byte align, a 2 bytes hole was inserted before st_mode when 
kernel make. but there are no problem in user application.
    I have change it in my code, add two bytes space after sum_NoLongerUsed.
and everything is ok.


*******************************
    Another problem is in yaffs tools, there are many problem when make image 
file, and I have change it.
    Are these really bugs? Did you found and how to handle them?
