Turbine Posted July 8, 2019 Share 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 Link to comment Share on other sites More sharing options...
Igor Posted July 8, 2019 Share Posted July 8, 2019 You set speed to 153200. Ofc it can't work. Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

None of the SOC guides I followed mentioned which pins to link. 1 Link to comment Share on other sites More sharing options...
