Update Instructions

  1. Download the latest .uf2 firmware file to your computer.

  3. Connect a USB-C cable from Crossflow (next to the power jack) to your computer.
  4. Press and hold both the A and B buttons on Crossflow while you plug in the power cable. Continue holding A and B while the four LEDs between them light up one at a time, left to right. 
  5. After the fourth LED (next to B) lights up and turns off, you can stop holding the A and B buttons. You should see the A and B LEDs alternately turning on and off.
  6. You should see a new drive called “Crossflow” appear on your computer, as if you plugged in a flash/thumb drive. 
  7. Drag and drop the .uf2 firmware file onto the “Crossflow” drive. 
  8. You should see the PRESET, TRIGGER MODE, and TAP SYNC LEDs light up one at a time from left to right, indicating the progress of the update.
  9. When the update has successfully completed, the A and B LEDs along with the first three TRIGGER MODE LEDs will light up and stay lit.
  10. Remove the power cable from Crossflow and plug it back in.
