HDMI Input on i.MX6 SBC

[#1]

This is a demo of the Nitrogen6X with BD_HDMI_MIPI daughter board. The Nitrogen6X is an i.MX6-based Single Board Computer (SBC) designed for both development and production use.  The BD_HDMI_MIPI daughter board utilizes the Toshiba TC358743XBG HDMI to MIPI CSI part to convert the HDMI signals to MIPI. The BD_HDMI_MIPI can be used with our Nitrogen6X, BD-SL-i.MX6, Nitrogen6_MAX boards as well as the Nitrogen6X_Carrier.  The daughter board can be used for evaluation as well as software development.  Please contact Boundary Devices for custom version.

This demo shows the Nitrogen6X running Yocto based on 3.10.17 kernel and displaying the output of our Nitrogen6X_SOM on a 10.1" LG BD101LIC1 display.

Hi pejmankalkhoran

Could you tell me the input resolution and frame rate ?

Did you achieve 1080p60 input with iMX6's MIPI CSI-Rx ?
