Good day dear All. I've installed latest yaffs and latest mtd from CVS and receive some (not some, a lot of) next error messages: **>>ecc error unfixed on chunk 32:0 **>>ecc error unfixed on chunk1 32:1 for a lot of chunks. These errors I've received just at the mount procedure, or when I'm trying to do, for example, ls. I have no such problems with previous yaffs and mtd versions. Also I have a short look on sources, and this error messages comes from yaffs_ReadChunkFromNAND function (yaffs_tagscompat.c) else if(nspare.eccres2<0) { T(YAFFS_TRACE_ERROR,(TSTR("**>>ecc error unfixed on chunk1 %d:1\n"),chunkInNAND)); } at error case both nspare.eccres2 and nspare.eccres1 equivalent to -1. I try to compared with previous versions, and nspare.eccres2==nspare.eccres1==0 for chunk 32. Please, can you help and explain me, where is this problem could be? Thank you.
