# Debugging
It is possible to debug AGL images on Raspberry Pi using 3.3V USB to serial cable, such as [Olimex USB-Serial-Cable-F](https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-Serial-Cable-F/), connected to the UART of the board. Follow the instructions below to connect a cable to the board (do it on your own risk, no warranty is provided):
* Connect the BLUE wire if you are using Olimex USB-Serial-Cable-F to pin 6 of Raspberry Pi,
* Connect the RX line of the cable (GREEN wire if you are using Olimex USB-Serial-Cable-F) to pin 8 (TX line) of Raspberry Pi,
* Connect the TX line of the cable (RED wire if you are using Olimex USB-Serial-Cable-F) to pin 10 (RX line) of Raspberry Pi.
* Plug the USB connector of the cable to your computer and use your favorite tool for serial communication, for example on Ubuntu and other Linux distributions you may use screen:
```
sudo screen /dev/ttyUSB0 115200
```
Pay attention that the colours of the cable may vary depending on the vendor. If you have USB console cable from Adafruit please have a look [here](https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/connect-the-lead).
