Fight for the bytes! Fun with Four Megabytes Flash
2018-12-28, 21:00–21:20, OIO lecture arena

The majority of Freifunk mesh routers only have 4mb flash and 32mb memory. The talk wants to start a discussion about possibilities and limits for future support of these devices.


Lot's of mesh communities and even OpenWrt want to drop support for 4mb flash / 32mb memory devices. Where is the size and memory increase coming from? Can we do it in a different way or do we have to accept defeat?

  • Forcing OpenWrt to diet: What knobs can we tweak? What gains and tradeoffs can we expect?
  • A short introduction to ubus over HTTP
  • Stupid ideas and experiments.
