Chapter 20

Supporting the i.MX53 Camera Sensor Interface CSI0

This chapter provides information about how to use the expansion connector to include support for a new

camera sensor on an i.MX53 reference board. It explains how to do the following:

• Configure the CSI unit in test mode (Section 20.3, “Configuring the CSI Unit in Test Mode”)

• Add support for a new CMOS sensor in the i.MX53 BSP (L2.6.31_10.07.11) (Section 20.4,

“Adding Support for a New CMOS Camera Sensor”)

• Set up and use the I

C interface to handle your camera bus (Section 20.5, “Using the I

C Interface)

• Load and test the camera module (Section 20.6, “Loading and Testing the Camera Module”)

It also provides reference information about the following:

• Required software and hardware

• i.MX53 reference CSI interfaces layout (Section 20.2, “i.MX53 CSI Interfaces Layout”)

• CMOS sensor interfaces (CSI) supported by the i.MX53 (IPU) (Section 20.7.1, “CMOS Interfaces

Supported by the i.MX53)

• i.MX53 EVK CSI parallel interface (Section 20.7.2, “i.MX53 CSI Parallel Interface”)

• i.MX53 CSI test mode (Section 20.7.3, “Timing Data Mode Protocols”)

20.1 Required Software

In Freescale BSPs, all capture devices are based on the V4L2 standard. Therefore, only the

CMOS-dependent layer needs to be modified to include a new CMOS sensor; all other layers have been

developed to work with V4L2.

Required development tools are as follows:

• Linux host with i.MX53 Linux L2.6.31_10.07.11 or newer

• Serial port terminal (such as Hyperterminal, TeraTerm, Minicom).
