Hi All,
I have ported the yaffs2 file system to Threadx OS. The nand flash used is of size 256 mb.
I am able to mount, create the files, directories, file read, write,dump etc and unmount it.
After unmount, again able to mount it and it restores from checkpoint succesfully.In the second time if i try to create the files of size greater than the block size (i.e) exceeding the current block and moving to next block(seems
like checkpointed block).In that case it is skipping the checkpointed block and continue its writing in the next block with messages in the console
"Block was not erased, yaffs write require 2 attempts" and file created in flash.and after that unmount is done at last...
Third time,during mounting, some error messages are seen in the console and entire file system gets corrupted.
Checkpoint block count wrong dev 1 count 0
Erased block count wrong dev 975 count 976
Freechunks verification failure 63823 63887 -64
yaffs: restored from checkpoint
Freechunks verification failure 63823 63887 -64
Could anyone please help me out in solving this issue. Any suggestions are welcome.
Thanks,
Dhivya
