At the moment ECC reads and writes are still being handled by the low level core of libflash. ECC should be none of libflashes concern, it is primarily a hardware access backend. It makes sense for blocklevel to take care of ECC but currently it has no way of knowing. With some simple modifications (which are rudimentary at the moment and will need a performance improvement) blocklevel can handle ECC, and with a little more effort this can be extended to provide read and write protection in blocklevel.
