Hi,
I'm using 4GB NAND Flash on my AT91RM9200 board, I can't mount yaffs2 partions \

Debugging into yaffs2 source code, I found the code which caused the Oops:
function yaffs_AddOrFindLevel0Tnode() In yaffs_guts.c:
} } else { /* top is level 0 */ if(passedTn) { \
memcpy(tn,passedTn,(dev->tnodeWidth * YAFFS_NTNODES_LEVEL0)/8); \
yaffs_FreeTnode(dev,passedTn); } }
tn is a NULL pointer when fStruct->topLevel == 0 , fStruct->top == 0 and passedTn != \
NULL:
/* Traverse down to level 0, adding anything we need */
l = fStruct->topLevel; tn = fStruct->top;
Then I tried to use no-checkpoint option after system reboot:

It seems that my yaffs filesystem can not work(be mounted) steadily, I don't know If \
it's a hardware or software problem.
Can somebody please help me.
Thank you very much!

Debugging into yaffs2 source code, I found the code which caused the Oops:<BR>
function yaffs_AddOrFindLevel0Tnode() In yaffs_guts.c:<BR>
<BR>
}<BR> } else {<BR> /* top is level 0 */<BR> if(passedTn) \

YAFFS_NTNODES_LEVEL0)/8);<BR> yaffs_FreeTnode(dev,passedTn);<BR> \
}<BR> }<BR> <BR>
tn is a NULL pointer when fStruct->topLevel == 0 , fStruct->top == 0 and \
passedTn != NULL:<BR> <BR>
/* Traverse down to level 0, adding anything we need */<BR>
l = fStruct->topLevel;<BR> tn = fStruct->top;<BR>
<BR>
Then I tried to use no-checkpoint option after system reboot:<BR>

It seems that my yaffs filesystem can not work(be mounted) steadily, I don't know If \
it's a hardware or software problem.<BR> <BR>
Can somebody please help me.<BR>
<BR>
<BR>
Thank you very much!<BR>
