The Mayans were writing with knotted rope around 1900BCE, so I would very much say it wouldn't be beyond possibility. Most of the early use was for tracking the seasons for religious rites - a pressure for developing writing that would exist across most early cultures.
I wonder about the knotted rope. How much information could it contain? Not very much. It's hard to imagine it being very useful.
Not sure which technology OP is talking about, but quipu at least are can store information like census records and dates. Similar concept.
