Please use the MYNT EYE TOOL to upgrade the firmware

You can download the firmware and MYNT EYE TOOL installation package in the Firmwares folder of MYNTEYE_BOX . The file structure is as follows:

├─...
└─setup.zip                    # MYNTEYE TOOL zip

• Open device manager, locate WestBridge_driver device, and right click Update Driver,select [application directory]WestBridge_driver\[corresponding system folders](If it is more than win7, choose wlh)\[system bits] .
• For example,if it is the win10 64 bit system computer,and the application is installed under the default path,you should select C:\Program Files (x86)\slightech\MYNT EYE Camera Tool\wlh\x64.
• After the installation driver is successful, you can find the Cypress USB BootLoader device in the device manager.
• Then plug in the camera and open the application again to update.

Warning

During the first time you open the MYNT® EYE camera after a firmware update, please hold the camera steadily for 3 seconds, for a zero drift compensation process. You can also call the API RunOptionAction(Option::ZERO_DRIFT_CALIBRATION) for zero drift correction.
