Peripheral MIPI[edit | edit source]

The MIPI interfaces available on iMX8M SoC are following described:

  • The Camera Serial Interface (CSI) is a specification of the Mobile Industry Processor Interface (MIPI) Alliance. It defines an interface between a camera and a host processor.
  • The Display Serial Interface (DSI) is a specification by the Mobile Industry Processor Interface (MIPI) Alliance aimed at reducing the cost of display controllers in a mobile device. It is commonly targeted at LCD and similar display technologies.

The two CSI interface on MITO 8M SOM:

  • CSI1 is avaiable on SODIMM connector pinout
  • CSI2 is avaiable on ONE PIECE expansion connector J5

The DSI interface is internally used on MITO 8M SOM to generate an LVDS output interface. More details on LVDS section.

Description[edit | edit source]

The MIPI CSI port supports the following standards and features:

  • Configurable interface logic to support most commonly available CMOS sensors.
  • Scalable data lane support, 1 to 4 Data Lanes
  • Support for CCIR656 video interface as well as traditional sensor interface.
  • 8-bit / 16-bit / 24-bit data port for YCbCr, YUV, or RGB data input.
  • 8-bit / 10-bit / 16-bit data port for Bayer data input.
  • Implements all three CSI-2 MIPI layers (Pixel to byte packing, low level protocol, Lane management)

Pin mapping[edit | edit source]

The Pin mapping is described in the Pinout table section
