Quote from another post of how this issue is solved:

Configuring kernel before building - #27 by TE999

Here is the steps I did:

  1. add “deb http://apt.radxa.com/stretch/ stretch main” to /etc/apt/sources.list
  2. get the repository key: “wget -O - apt.radxa.com/stretch/public.key | sudo apt-key add -”
  3. update your apps: “sudo apt-get update && sudo apt-get upgrade”
  4. install rockchip-overlay etc:
    sudo apt-get install rockchip-overlay
    sudo apt-get install rockchip-fstab
    sudo apt-get install rockpi4-dtbo
  5. edit /etc/hw_intfc.config, turn on uart2, uart4, and the overlay disables the console.
  6. update kernel:
    apt-get install linux-4.4-lastest
  7. update u-boot:
    sudo su
    apt-get install rockpi4b-rk-u-boot-lastest
    cd /usr/local/sbin/
    ./rockpi4b_upgrade_bootloader.sh
  8. reboot, type “who” in xterm, should shows you as the only user, nobody on ttyFIQ0
  9. In Z-Way server or Home Assistant, change the default uart setting from ttyAMA0 to ttyS2.
  10. reboot. who says you don’t need to reboot Linux often? :-/
