It'll be worth it because you'll be able to have a nice one click menu and drop directly into a serial port terminal on Windows in the Windows Terminal Read this whole post, there's a lot initially but there's really just two or three small pieces. (even the tutorial is for arduinos, it should be similar for every 'COM device')įor those, who want to save 1$ for an USB-UART bridge, you can spend 10$ for an OrangePi Zero and use its spare UARTs to log into an other SBC.I hope that this blog post is found and helps someone.

Run devmgmt.msc and search for the serial device (in this case COM3) and connect to it via PuTTY (thanks to windows 10 ( q=find+arduino+port+windows+10&sourceid=opera&ie=UTF-8&oe=UTF-8): I assume if you use the same settings in something like putty on windows and you check which 'serial' device shows up in *where windows shows connected devices - I forgot it* you should be able to access it from windows (someone motivated may confirm this).

Several board (see list) for which official armbian images exist (or csc images can be built) have no HDMI display.

Normally you connect the USB-UART bridge to your host computer (and the SBC) and start picocom/putty before you power the board to ensure you get the full bootlog and not only parts of it. Should be similar to Linux whereas the naming differs a bit. COM11 is just an example and needs to be checked first, Speed (baud) needs to be changed when you deal with the few RK boards which need 1500000. Something like the picture in USB Gadget Mode part of the tutorial should show up)Īrmbians default settings are (expect some RK devices): In Device Manager, expandPorts (COM & LPT) and you should see a COM port which will be your Arduino as shown in the image below. Open the Device Manager window by right-clicking the Windows 10start button in the lower left of the screen and then selecting Device Manager on the menu that pops up. usb 3-2: ch341-uart converter now attached to ttyUSB0įor windows 10 ( q=find+arduino+port+windows+10&sourceid=opera&ie=UTF-8&oe=UTF-8) usbserial: USB Serial support registered for ch341-uart usbcore: registered new interface driver ch341 You've to check dmesg (linux) or run devmgmt.msc (windows) to know which device you use. Tinkerboard) and then connect: GND -> GND You've to figure out which pins on your SBC are debug UART (they've mostly a own 3 pin header, sometimes it's on the large pin header e.g. Most of these USB-UART bridges have jumpers for 5V and 3.3V, make sure that you use the 3.3V. The only thing which is needed is that the signal-level matches with your SBCs needs (this is mostly 3.3V expect some Odroids e.g HC1 which has only 1.8V!).
I prefer the (probably fake) FDTI on the right side, but the CH341 does also a good job: Normally it doesn't matter which one you use. There are various USB-UART bridges e.g FT232 (and fakes of them, cause FDTI is expensive ), CH340/1,PL2303 or CP2102 If you use Linux on your host system I prefer picocom (something like minicom will also do the job) which can be installed: We need an Terminal program to access the console. As a reminder an USB-UART bridge is always prefered over USB gadget mode whenever possible (UART get's initialized before the gadget driver and also before HDMI, means even if you don't get a proper output from HDMI or gadget mode console, it is possible that UART will give you the needed information). For some boards, armbian implements an USB gadget mode (a 'fake' serial console over microUSB) describen below. This short tutorial should give you an introduction how this works. When SSH/Display access isn't possible access to console via UART is the best way to get a clue where your SBC hangs. Access to a console can be mandatory when you SBC doesn't work as expected (e.g Network or HDMI output doesn't work).
