## Building for different boards
If you need to build firmware for other boards, follow the instructions for building different boards at github.com/raspberrypi/pico-sdk

## Flashing firmware

The fastest method to load firmware onto a RP2040-based board for the first time is by mounting it as a USB Mass
Storage Device. Doing this allows you to drag a file onto the board to program the flash. Go ahead and connect the
Raspberry Pi Pico to your computer using a micro-USB cable, making sure that you hold down the BOOTSEL button as you do so, to force it into USB Mass Storage Mode. Drag the ei_rp2040_firmware.uf2 file from build folder to newly appeared USB Mass Storage device.
