Simple Guide For Setting Up OTG On The Raspberry Pi

What is OTG?

OTG (On-The-Go) is a feature that allows USB devices to act as either a host or a peripheral device. When used as a host, a Raspberry Pi can connect to other USB devices like mice, keyboards, and USB flash drives. When used as a peripheral device, a Raspberry Pi can be connected to a computer or a smartphone.

Enabling OTG (On-The-Go) on a Raspberry Pi can be a useful feature for various projects, as it allows the Raspberry Pi to act as a USB device, such as a mouse or keyboard, when connected to another device. Here is a step-by-step tutorial on how to enable OTG in Raspberry Pi:

Step 1: Update the Raspberry Pi
Before enabling OTG, make sure that your Raspberry Pi is up-to-date. Open the terminal and run the following command:

sudo apt-get update && sudo apt-get upgrade

This command will update the Raspberry Pi to the latest version.

Step 2: Modify the boot configuration file
To enable OTG, we need to modify the boot configuration file. To open the configuration file, enter the following command:

sudo nano /boot/config.txt

This will open the configuration file in the nano text editor.

Step 3: Add the OTG configuration
Add the following line to the bottom of the file:

dtoverlay=dwc2

This line enables the OTG driver on the Raspberry Pi.

Step 4: Save and exit
To save the changes and exit the nano text editor, press Ctrl + X, then Y, and finally Enter.

Step 5: Modify the cmdline.txt file
Next, we need to modify the cmdline.txt file. To open this file, enter the following command:

sudo nano /boot/cmdline.txt

Step 6: Add the OTG configuration
Add the following text to the end of the line:

modules-load=dwc2,g_ether

This line loads the required modules for OTG.

Step 7: Save and exit
To save the changes and exit the nano text editor, press Ctrl + X, then Y, and finally Enter.

Step 8: Reboot the Raspberry Pi
Finally, reboot the Raspberry Pi by entering the following command:

sudo reboot

Step 9: Connect the Raspberry Pi
Once the Raspberry Pi has rebooted, connect it to another device via a USB cable.

Congratulations! Your Raspberry Pi is now ready to act as a USB device using the OTG configuration.

NOTE: All Raspberry Pi models have a USB port that can be used as OTG (On-The-Go) with the right configuration. However, some models may require additional hardware, such as a USB OTG cable or an OTG adapter, to use the USB port as a client device.
