Не работает Orange Pi3 Lts + Skr 1.4 UART

Помогите решить проблему, Прошил пишку клипером, настроил подключение по UART (GND, RX, TX пишки (отдельные 3 контакта на плате serial0 в настройках) подключал к GND, RX, TX слота TFT skr 1.4 GND к GND RX к TX и TX к RX ). Прошил skr 1.4, но при запуске веб интерфейса пишет вот это. 

Printer is not ready

The klippy host software is attempting to connect. Please
