This guide will walk you through the process of flashing the latest firmware onto your OMI device.

Downloading the Firmware​

  1. Go to the OMI GitHub repository and navigate to the " OMI > firmware" section.
  2. Find the latest firmware release and bootloader, then download the corresponding .uf2 files.

Or download these files

Putting OMI into DFU Mode​

  1. Locate the DFU Button: Find the small pin-sized button on the OMI device's circuit board (refer to the image below if needed).

  2. Prepare a Pin: Use a small pin or similar thin tool to press the tiny button.

  3. Press the DFU Button Twice: Using the pin, quickly press the DFU button twice in succession.

  4. Check for Recognition: After pressing the button twice, your computer should recognize a new drive.

  5. Verify the Drive Name: Look for a drive named /Volumes/XIAO-SENSE on your computer. This indicates that the OMI device has successfully entered DFU mode.

Flashing the Firmware​

  1. Locate the .uf2 files you downloaded earlier.
  2. Drag and drop the bootloader .uf2 file onto the /Volumes/XIAO-SENSE drive:
  3. The device will automatically eject itself once the bootloader flashing process is complete.
  4. After the device forcibly ejects, set the OMI device back into DFU mode by double-tapping the reset button.
  5. Drag and drop the OMI firmware file onto the /Volumes/XIAO-SENSE drive:

Congratulations!​

You have successfully flashed the latest firmware onto your OMI device. You can now download the OMI companion app to fully utilize your device:
