Two different reads: root@OpenWrt:/# dd bs=1 skip=262148 count=6 if=/dev/mtd0 "u�������6+0 records in 6+0 records out root@OpenWrt:/# dd bs=1 skip=262148 count=6 if=/dev/mtd0 "u���6+0 records in 6+0 records out I don't think this is the bug in dd/kernel/uclibc - it would probably expose when writing to a file too. Maybe it's something with busybox. I'm not sure of cause.
