Here’s a tutorial on how to reset a Raspberry Pi Pico to factory default using a Windows machine:
Step 1: Prepare your Raspberry Pi Pico
First, make sure your Raspberry Pi Pico is connected to your Windows machine via USB. Ensure that your computer recognizes the Pico, and the Pico’s red LED should light up.
Step 2: Download and install the Pico Python SDK
To erase the firmware on your Raspberry Pi Pico, you will need to install the Pico Python SDK. The SDK contains a command-line tool called “rp2040.py,” which is used to interact with the Pico’s flash memory.
To download and install the Pico Python SDK, follow these steps:
- Go to the Raspberry Pi Pico website (https://www.raspberrypi.com/products/raspberry-pi-pico/)
- Click on the “Documentation” tab and select “Getting started with Raspberry Pi Pico.”
- Scroll down to “Getting started with MicroPython” and follow the instructions to install the Pico Python SDK.
Step 3: Open a Command Prompt
Once you have installed the Pico Python SDK, open a Command Prompt by pressing the Windows key + R, typing “cmd” and pressing Enter.
Step 4: Navigate to the directory where the Pico Python SDK is installed
In the Command Prompt, navigate to the directory where the Pico Python SDK is installed. This is typically “C:\Program Files (x86)\Raspberry Pi Pico.”
To navigate to the directory, type the following command and press Enter:
cd C:\Program Files (x86)\Raspberry Pi Pico\
Note: If you installed the Pico Python SDK to a different directory, replace the path above with the correct path.
Step 5: Connect to the Raspberry Pi Pico using rp2040.py
Once you are in the Pico Python SDK directory, you can connect to the Raspberry Pi Pico using the rp2040.py tool. To connect to the Pico, run the following command in the Command Prompt:
python.exe rp2040.py -p COM3
Note: The “-p” option specifies the serial port that the Pico is connected to. Replace “COM3” with the serial port on your computer where the Pico is connected.
Step 6: Erase the firmware
Now that you are connected to the Raspberry Pi Pico using rp2040.py, you can erase the firmware on the Pico’s flash memory. To do this, run the following command:
python.exe rp2040.py -p COM3 erase
This command will erase the entire contents of the Pico’s flash memory, effectively resetting it to factory default.
Step 7: Disconnect the Raspberry Pi Pico
Once the erase command has completed, you can disconnect the Raspberry Pi Pico from your computer. The Pico will now be in its factory default state, ready for you to program it with new firmware.
Resetting a Raspberry Pi Pico to factory default is a simple process that can be done using the rp2040.py tool included in the Pico Python SDK. By erasing the firmware stored on the Pico’s flash memory, you can start with a clean slate and program the Pico with new firmware.
