Firmware and Configuration Files
How to Update or Change Firmware
- Power down your Apple, and remove the A2 VidGA from the Apple.
- Hold down the “BOOTSEL” button on the board.
- Plug the A2 VidGA into a computer with a MicroUSB data cable. (Be sure it’s a data cable!)
- Let go of the button.
- You should see the unit mount to the Desktop or My Computer (or similar) of your computer as a USB flash drive. It should be named “RPI-RP2”
- Copy the .uf2 file from your computer to this flash drive.
- Wait ten seconds. The flash drive should automatically dismount/disappear.
- Unplug and reinstall into your Apple.
Self-Install VGA Cable
Want to make your own VGA cable? It’s easy!
- Install a 10-pin header on both sides of the cut line on the board.
- Score the board on both sides along the cut line, and snap off the VGA port.
- Connect a 10-pin ribbon cable between the board and the VGA port.
- Use standard hex bolts to attach the VGA port to the rear of your Apple!
