Turbine Posted July 8, 2019 Posted July 8, 2019 (edited) Armbianmonitor: http://ix.io/1NZH Hi, I'm new to the Armbian/Alt PI scene, coming from a RPI Zero W. I'm needing to interact with my PI using a CH340G (is it compatible) USB to TTL dongle. I've also trjed a CH351A device, put it into UART mode. Unfortunately, I get nothing from the PI. Despite using the primary RX/TX pins. I've also tried enabling all of the UART pins using armbian-config, and using another set of pins - to no avail. Please view my setup below. I've run out of ideas of where I'm going wrong. I've tried these images: Armbian_5.90_Nanopineo2_Debian_buster_next_4.19.57 Armbian_5.90_Orangepione_Ubuntu_bionic_next_4.19.57 Reference: http://linux-sunxi.org/File:Orange_Pi_One_UART.jpg Edited July 8, 2019 by Turbine

Ofc it can't work. @Turbine set the speed inside puTTY also to 115200 like in the hardware-properties of windows for the usb-dongle AND you did make a small beginners failure You have connected RX to RX (Orange <-> Orange) and TX to TX (Green <-> Green). Normally you have to connect crossover: RX to TX and TX to RX but GND <-> GND

None of the SOC guides I followed mentioned which pins to link. 1
