Introduction– 4

1 Introduction

The SBC (Single Board Computer) kits from PHYTEC represent an ideal basis for testing and the first design steps

with phyCAM camera modules. The kit forms the starting point for your development project. The kit can be used to

develop and test application software before your own adapted hardware is available. It is also an optimal platform

for testing special hardware extensions before you create a complex application board.

This optional step secures your design while at the same time provides software developers with an opportunity to

adapt newly added hardware components. Extensions can be easily connected via the extension interfaces of the

baseboards included in the kit. In the simplest case, a freely wired hole grid structure is sufficient.

For certain combinations of controller modules, camera modules, and lenses, we offer ready-made kits. If the

combination you require is not available, we recommend that you first put a similarly-equipped kit into operation

and then connect the camera you require to the kit.

We will be happy to advise you on the best way to carry out your project.

2 SBC Kit Start-Up

Before you try out the camera and image processing functions, we recommend that you first familiarize yourself

with the basic functions of the kit and the associated development environment. Each kit contains a Quick Start

Guide that guides you through installing the software on your development PC and configuring the hardware.

2.1 Before You Start

The following components are required for the camera setup:

PHYTEC SBC-Kit with power supply and serial connection (RS232 or USB)

Camera module with camera cable, lens holder, and lens

Network cable

HDMI monitor with an HDMI cable (not included in the kit)

If you have ordered the corresponding kit as an Embedded Imaging Kit, all hardware components required for

installation are already included.

As a rule, both the extension of an existing kit by one camera and the extension of an existing video kit by additional

cameras is possible without problems with an existing phyCAM interface.

Before connecting and starting up the camera, carry out the first steps of the "Quick Start Instructions" of the

respective kit. To start the scripts on the module, follow the steps to establish a serial connection with the module.

You can use the terminal program suggested in the manual or your own terminal program.

To transfer saved image files to a PC (host) via Ethernet, follow the steps to establish an FTP connection. You can

use the FTP server suggested in the manual or your own FTP server.

3 Connecting and Starting the Camera

When you purchase an SBC kit, you will receive the PHYTEC guarantee. If you encounter any difficulties during

installation, PHYTEC support will help you!

3.1 Overview

The i.MX 8M Plus Microcontroller supports two MIPI CSI-2 camera interfaces:

On the phyCORE-i.MX 8M Plus, the CSI1/CAM1 and CSI2/CM2 camera paths go out as CSI-2 MIPI signal:

CAM_1 (CSI1) and CAM_2 (CSI2) Present on Connector X1

Note

Depending on the kernel version, the software installation may differ in some details from the described

procedure.

Connecting and Starting the Camera– 7

On PHYTEC or customer carrier boards, the interfaces are led out as phyCAM-M. For more information on phyCAM-

M, see the phyCAM-Manuals on our website1.

On the phyBOARD-Pollux baseboard, the camera interfaces are led out as phyCAM-M (MIPI CSI-2) interfaces. Here

you can connect different phyCAM-M camera modules:

phyCAM-M Camera Interfaces of phyCORE-i.MX 8M Plus (Quad) and the output on the phyBOARD-Pollux-i.MX 8M

Plus

The BSP shipped with the Kit includes the software drivers for the supported phyCAM-M camera modules. The

drivers are compatible with v4l2. GStreamer scripts are also included for the evaluation of the camera modules. If

you need the camera interface to connect to your own camera module, an adapter to phyCAM-M is necessary.

4 Camera Connectors on the Pollux - Carrier Boards

The development kits for the i.MX 8M Plus phyBOARD-Pollux contains:

one carrier board (phyBOARD-Pollux)

one phyCORE-i.MX 8M Plus module SOM (phyCORE-i.MX 8M Plus)

The phyCORE-i.MX 8M Plus is plugged into the carrier board.

On the phyBOARD-Pollux baseboard (PBA-C-17), we convert the MIPI CSI-2 interfaces into a phyCAM-M standard.

phyCAM-M camera interface 2 (support on connector X12)

4.1 Connecting the phyCAM-M Camera

A type-A FFC cable (stripped and reinforced on the same side) is supplied with the kit. This ensures the correct

signal assignment between the camera and the baseboard in the kit.

The position of the camera socket on the baseboard can be found in the hardware manual2of the kit. Parallel to the

connector designation (e.g. X100), some basic boards also have "CAM" printed on the board. The phyCAM-M

interface is a 30-pin FFC socket, which can be installed standing or lying on the board.

The FFC cable is plugged in exactly the same way as the cable is plugged into the camera FFC socket.

Note

If you use the phyCAM-M interface, use an FFC cable that is especially suitable for FH41 connectors (e.g.

PHYTEC WF271). Standard FFC cables can cause a short circuit.



Note

In the vertical version of the FFC socket, the contacts are also on the side opposite the bracket.

Open the lock of the 30-pin FFC connector on the camera by lifting the lock upwards.

phyCAM-M Flip Lock – FCC Socket Camera Connection

Plug the 30-pin FFC cable into the FFC socket with the contact surfaces facing downwards until you feel the

stop. The reinforcement of the FFC cable (usually highlighted in color) points to the bracket of the socket.

Lock the FFC socket by carefully pressing it down on the bracket.
