Hi,

can someone please suggest a UART USB cable that works with the BananaPi F3 board? I have a future technology device international FTDI FT232RL USB UART TTL 3V3 cable and it doesnt seem to work at all(the cable gets recognized via lsusb, i get a ttyUSB0 but no output when running picocom -b 115200 -r -l /dev/ttyUSB0).

I use this one https://www.kubii.com/en/hub-cables-adapters/3650-usb-c-to-uart-adapter-3272496309890.html

Have you tried with with anything else than picocom ? I use screen

Hi Matthieu,

I tried out gnu screen but it doesn’t work either(no output).Thanks for your suggestion will purchase one to see if it works.

Something I had almost forgot : did you try putting TX on RX and RX on TX ? First time I tried TX on TX and RX on RX and got no output and was then told that sometimes, it has to be the inverse, depending on the board.

Hi Matthieu,

swapping the TX and RX solved the problem. Thanks again for your help! :slight_smile:
