====== Firmware Update ======

This document will walk through how to load new firmware onto a device.

We have a number of products so the first thing you'll need to do is determine if the reset button is accessible without opening the case.

----

===== External Reset =====

For these products you just need a paperclip to press the reset button.
  * S1D Digital Controller
  * S1A Analog Controller
  * 8K2 Controller

There will be a small hole close to the center of the unit through which you can place the straightened end of a paperclip through to press the reset button. (A SIM card ejector pin also works well.)

===== Internal Reset =====

For the following products you will need to remove the bottom cover of the device to access the reset button.
  * The Big Button
  * The Button
  * The Dual Button
  * B3 Three Button Controller
  * Footswitch
  * Dual Footswitch
  * MIDI Controller LC
  * MK1 Controller

The PCB will be wrapped in blue tape, with a black dot indicating where the reset button is. Pressing down on the black dot will press the reset button. Press it and you should recognize the feel of a button being pressed and hear a slight "click" sound.

You will need to **press and hold the reset button** down //while plugging the device into your computer//.

Doing this will cause the device to go into **USB Storage Mode** and will mount on your computer like an external drive.

You should see a new drive appear on your computer. It will be named **RPI-RP2**.

----

The drive will contain two files. Ignore the files, **do not delete or attempt to edit them**.

----

Copy the new **UF2** file to the **RPI-RP2** drive. It will disconnect/dismount from your computer and the update should be complete.

Test it out. If the update did not seem to work try it again.

===== Where do I get a UF2 file? =====

Typically we will provide you one via email after discussing how you want the device programmed.
