ECC errors is a normal phenomena on OneNAND and they happen quite often. Flash-aware file-systems like JFFS2 or UBIFS are able to handle them gracefully.
since ECC errors are supposed to be handled by upper level SW, we do not really have to print these messages, and we may consider them as debugging prints.
I advise you to save important data every week. Everything can die. Sometimes a reflash could wake up again.
