Fingers crossed ...

Searching for EcoNet in this forum should tell you that this SOC has no linux- or OpenWrt support so far.

So what ?

There's plenty of hw out there running Linux, but lacking support in the mainline Linux kernel.

What's the goal with your threads?
Name drop as many unsupported devices as possible?

Does EcoNet comply with the GPL? If so, you'd stand a chance.
