I have a VisionFive 2 RISC-V board, but according to another thread the both gigabit network interfaces are currently not supported. So my plan if nobody started with it, I want to create an driver for it. So my question because I never created a driver for FreeBSD before, is there a good starting point?
The reason is I want use the VisionFive 2 with FreeBSD as firewall for my home network. Therefore I need network support. And is also a good for the purpose of education.
EDIT:
I think it should be possible for me to create a driver. The DTS from the network interface source from Linux for the JH7110 SoC:
Is a Synopsis compatible network interface. Are there any existing drivers which use a Synopsis network IP?
EDIT:
Yes there is an driver sys/dev/dwc/if_dwc.c. But should be version 5.20 compatible from the IP core.
