Hi!
 
I use = YAFFS via=20 direct interface.
 
When = YAFFS=20 encounters unrecoverable ECC error during file read it retires the block = but the=20 application gets no notification from the file system that the file data = is=20 corrupted (except for printed error message).
 
One = could pass such=20 notification via global variable from directly from = yaffs_ReadChunkFromNAND() to=20 application. I'd like to know how do you deal with this problem or think = it=20 should be dealt with.
 
Thanks.
