Install the UF2 Bootloader

At Adafruit, we really like the UF2 bootloader for installing software like CircuitPython on microcontrollers.

UF2 allows you to drag-and-drop UF2 files and has a nice LED/NeoPixel indicator. No special

DFU/firmware-updater software is required and you can use any computer to program a UF2-bootloader

device.

But what do you do with a fresh chip, or if the UF2 bootloader on your device has become corrupted?

This guide will walk you through the steps of installing the UF2 bootloader using the ROM bootloader

built into all RT10xx chips using software called sdphost or sdphost.exe on your PC, Mac, or Raspberry Pi.

 You only have to perform this step once for fresh-from-the factory chips, or if somehow your

bootloader got corrupted. The 'USB in ROM' bootloader, thankfully, cannot be damaged, so you will

never need a JLink/OpenOCD hardware dongle to perform this task
