The Feather RP2040 DVI microcontroller ships running an 800x480 resolution demo over HDMI. Connect up a display to see a series of shapes, text and images on the display letting you know your board is working.
It's lovely, but you probably had other plans for the board. As you start working with your board, you may want to return to the original code to begin again, or you may find your board gets into a bad state. Either way, this page has you covered.
Step 1. Download the factory-reset.uf2 file
Save the following file wherever is convenient for you. You will need to access it to copy it to your board.
Step 2. Enter RP2040 bootloader mode
Entering the RP2040 bootloader is easy. Complete the following steps.
Before you start, make sure your microcontroller is plugged into USB port to your computer using a data/sync cable. Charge-only cables will not work!
To enter the bootloader:
- Press and hold the Boot button down. Don't let go of it yet!
- Press and release the Reset button. You should still have the Boot button pressed while you do this.
- Continue holding the Boot button until you see the RPI-RP2 drive appear.
- You can now release but Boot button.
The board will automatically reboot.
Connect a HDMI display at 800x480 resolution to the Feather to see a series of shapes, text and images on the display letting you know your board is working.
You've successfully returned your board to a factory reset state!
Flash Resetting UF2
If your board ever gets into a really weird state and doesn't even show up when loading code, try loading this 'nuke' UF2 which will do a 'deep clean' on your Flash Memory. You will lose all the files on the board, but at least you'll be able to revive it! Download the file below, and follow the instructions in Step 2 and Step 3 above to load this UF2. Then, start again at Step 1 to return your board to factory reset state.
