Putting the R PRO-1 in boot mode

This will cover how to put the R PRO-1 into boot mode.

This is needed to force the device into boot mode to reflash the firmware.

Method 1: Boot button only

You'll open the case, then hold the boot button while you plug in the USB-C cable.

1. Unplug your R PRO-1 from power and remove the back.

5. Continue with uploading the firmware document.

Method 2: Boot and reset buttons

You'll open the case, plug the board into your computer, then hold the boot button down while you press and release the reset button.

5. Plug your R PRO-1 into your computer, then put it in boot mode. Use both buttons, in this order:

  • Press and hold the boot button (the right button, shown in step 3). Keep holding it.
  • While you're still holding boot, press and release the reset button (the left button, shown in step 4).
  • Let go of boot.

Keep holding boot the whole time

Pressing reset by itself only restarts the R PRO-1. It goes into boot mode only when boot is held down while you press and release reset.

6. Continue with uploading the firmware document.
