As you can see in my previous mail, there are some minor changes too oob-layout selection. See patch against current yaffs-cvs. If you want to use the new functionality for mkyaffs too, set the ecc bytes in your image to 0xff and select the layout by ioctl (fd, MEMSETOOBSEL, &newsel). See patch. -- Thomas ________________________________________________________________________ linutronix - competence in embedded & realtime linux http://www.linutronix.de mail: tglx@linutronix.de
