Not supported at this point, neither the device itself, nor the SOC it is based on. While that doesn't make it totally impossible, the development would be all yours for the taking - and with the SOC-bringup, it would be a very, very steep learning curve and quite a few months++ of work.
I heard there is a way, but it’s difficult. You need to obtain the tools, SDK, and installation file from the source (FiberHome), or you need to build or fork the OS from scratch.
