This is a script to build a TP-Link MR3020 image for Cyber Spark.
You do this:
./build.sh
And then you install openwrt.bin as a firmware upgrade in the TP-Link web UI
at 192.168.0.1.
When it comes up it's going to be 192.168.1.1,
which is a different subnet than the TP-Link firmware uses.
OpenWRT has no root password by default, which means ssh won't work. Before doing anything else, telnet in to set a password:
telnet 192.168.1.1
