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