Note

Stay connected during the update process and use the correct Device and Interface.

For more detailed information, select the method you want to use below:

MSD

Prepare for setup

• At least one device.

• A binary file to update.

Step-by-step instructions on how to update via MSD

1. Use a USB-C Data Cable to connect the USB-C Data Port 2 of devices to the PC.

2. Once connected, the LEAPS MSD drive will appear on your PC. Open the LEAPS MSD drive.

For example, on Windows:

3. Download the LEAPS-UWBS-Firmware-v0.16.3.zip file to your PC. Use a program like WinZip or 7-Zip to extract the contents of the downloaded file.

4. Locate the binary file at LEAPS-UWBS-Firmware-v0.16.3/LEAPS-UWBS-Firmware-OpenOCD/udk1-leaps-uwbs-v0.16.3.bin. Copy this file to the LEAPS MSD drive.

For example, on Windows:

1. Wait for the copying and flashing process, until the copying is successful. The board will automatically reset as part of the process, the RGB LEDs will light up and the hardware will beep to indicate a successful update.

The device successfully updated the firmware. Enjoy the latest features and improvements.
