Procedure

Notes and Troubleshooting

Ensure you are not using VCP driver version 1.2.3.0. This

driver, which is known to have trouble with Xloader, may

already be installed on your computer if you have used the

Arduino Uno Board for another purpose. If version 1.2.3.0 is

already installed, go to your computer's Device Manager to

change the driver to version 1.2.2.0, which was downloaded

in Step 1.a:

a. Find the device in Device Manager and right click on it.

b. Select "Update driver software".

c. Choose "Browse my computer for driver software" and

provide the path to the VCP driver contained in the

software download in Step 1.a. The default path is C:\

Program Files (x86)\Honeywell\SensorEvaluationKit\

VirtualCOM. This will change the VCP driver to version

1.2.2.0, which you can then verify in the driver tab of the

device settings.

COM port

Ensure the COM port is set to the COM port identified in Step

3. The port settings may have been set for a different baud

rate when you installed your VCP driver. Use your computer's

Device Manager to verify the port settings and to change the

baud rate to 115200, if needed.

Baud rate

Ensure the baud rate in Figure 4 matches the baud rate

selected in the Device Manager port settings.

Bytes

The number of bytes given in Figure 4 is an example only. The

actual number may vary according to the specific Arduino

Firmware SEK002 version you downloaded. This byte count

may change as this file is updated.
