It's possible.

the unfinished code is at https://github.com/echoline/etherESP32
it would be cool to see an aijuboard with accelerated hardware devdraw
on the fpga if that's even possible, or other hardware like that

Supports ethernet, spi, usb otg, etc.  Thought about porting the
libstyx library from Inferno over to 
the STM32 platform. 

https://github.com/inferno-os/inferno-os/tree/master/tools/styxtest

Thin OS layer was provided by FreeRTOS.  STM32F4 specific HW was
accessed using libopencm3
https://libopencm3.org/

If interested...

I've recommended olimex.com in the past. They specialise in Open
Architecture Hardware. Their prices are very reasonable and product
range quite broad.
