HDMI Input for i.MX8 boards via MIPI-CSI

Published on April 27, 2020

We are pleased to announce support for the BD_HDMI_MIPI on our i.MX8 based Nitrogen boards. Although the i.MX8M and i.MX8M Mini processors do not natively support HDMI input, the Toshiba TC358743XBG HDMI to MIPI-CSI bridge enables this feature. You can find the specs on the daughter board for Nitrogen8M here and Nitrogen8M Mini here. Find below a video demo of the board in action. The specs of the setup in the video are as follows:

Board Specs:

Nitrogen8M running Yocto 3.0 Zeus + 10" Display Kernel Revision: 4.14.x_2.0.0_ga

HDMI Input Source:

Nitrogen6x MAX running Ubuntu Bionic 18.04 xfce 1080p Kernel Revision: 4.14.x_2.0.0_ga

Video Summary:

The 1080p output of the Nitrogen6 MAX feeds into the BD_HDMI_MIPI_8M which then connects to the DB_CSI_8M that is connected to the Nitrogen8M. Then, the HDMI video source shows up as an input video device on the Yocto OS GStreamer application:
