I am configuring an Ubuntu 20.04 on a RX1 board which is based on Rockchip RK3588 SoC
I have installed the image and fired the system with DHCP and was working, after that I changed the configuration to a static IP with this configuration:
---
network:
version: 2
renderer: networkd
ethernets:
eth0:
addresses:
- 10.0.20.21/24
routes:
- to: default
via: 10.0.20.1
dhcp4: false
dhcp6: false
nameservers:
addresses:
- 10.0.20.53
- 10.0.20.54
The IP is not accepted and I found an error in Syslog
ubuntu@ubuntu:~$ ip a s

If I configure the IP manually, everything is working correctly.
sudo ip link set eth0 up
sudo ip addr add 10.0.20.21/24 brd 10.0.20.255 dev eth0
sudo ip route add default via 10.0.20.1
ubuntu@ubuntu:~$ ip a s

What can I do to make netplan working ?
I have tried tu upgrade the system but with no success.
