          Hi ,

           

          1. The new CYPD4226-40LQXI is pre-programmed with I2C bootloader only.

          2. May I know whether you have grade Tools for CYPD4226-40LQXI of Mainboard of Lenovo yoga 920 or not? If you are customer of Lenovo yoga 920, strongly recommend you contact Lenovo for technical support.

          3. Could you please kindly figure out the driver you have been pointed out? Since the CYPD4226-40LQXI is connect to EC via I2C +INT, Is meaning of the I2C driver is failed to install on?

          4. Is the firmware of CYPD4226 comes from Lenovo or not?

           

          Best Regards,

          Lisa
