I provide you the firmware:
I search freelance (paid) support RTL9602C on this device. I need GPON, Wifi AP, IPv4 NAT, IPv6 route + DHCP prefix delegation client support.
If I understand correctly, you'd have to fund development/integration/upstreaming of
- a Lexra compile target support for modern GCC and friends
- a port of the current mainline Linux kernel to Lexra using that GCC
And only then will Openwrt devs accepts Pull requests for:
- generic SOC support for Lexra CPUs in Openwrt
How many Zeros does your budget have?
Yes, all will depand of the cost, but I have 200 ONU GPON to save. Then 3500USD for this group is well, maybe more with the next ONU group buy
