Unboxing and Setup Cables - Iris

 
 

Attention: the Quickstart Guide for BSP 2.8, based on the Ångström distribution, is not being updated anymore. Depending on your SoM, you have different options:

Vybrid and Tegra: the information is provided as-is and still accurate, since newer Toradex BSPs are not ported to those SoMs. Just keep in mind that the Guides are not being maintained anymore, even if we find bugs or outdated instructions.

Apalis TK1 (all variants), Colibri iMX6ULL (all variants), Colibri iMX7S 256MB and Colibri iMX7D 512MB: these computer on modules are still regularly maintained in our BSPs and, to get started, you must check the software page Toradex BSP Layers and Reference Images for Yocto Project. Since Torizon is not supported, at the moment a Quickstart Guide is not available.

All other i.MX-based SoMs: you have two options to get started with embedded Linux: the first is to follow the Quickstart Guide for Torizon, which provides the greatest out-of-the-box experience, or if you choose to use Yocto, check the software page Toradex BSP Layers and Reference Images for Yocto Project.

Overview

In this first lesson you will go through the process of unboxing your computer on module and carrier board and assembling the hardware. The following GIF illustrates what you will end up with:

Prerequisites

The following table lists the items required:

List of items required
VGA display/monitor and DVI to VGA adapter
Accessory kit :
  - 12V 30W power supply
  - USB-Serial converter
  - IDC to DB9 adapter cable
  - Ethernet cable
USB keyboard

As an option to buying the IDC to DB9 adapter, you might assemble one by following the instructions provided here.

Note: The DVI video output is configured to provide an analog signal by default in the Colibri family. Please make sure that your DVI adapter has the analog pins available - see DVI-A or DVI-I for more details.

Step 1

Remove the Iris Carrier Board and the Colibri Computer on Module from the blisters. Insert the computer on module into the X1 connector of the Carrier Board as tight as possible, with the module inclined ~30 to 45 degree in relation to the carrier board.


  • Connecting the computer on module to the Iris Carrier Board

Warning: Make sure that the module is well connected to the carrier board. The image below has some checkpoints highlighted.

Step 2

Connect the DB9 to IDC adapter cable to the X13 connector on the Iris.

Note: The adapter is included in the Toradex Cable Kit, the standard we used is normally called DTK or Intel standard.

Step 4

  • Connect the VGA display/monitor to the X4 connector through the DVI to VGA adapter. Note: The DVI output only has the analog signal enabled by default. To use the digital interface please refer to the FAQ section in the end of this lesson.

  • Connect an Ethernet cable to X15. Note: Ethernet network must provide DHCP and Internet to the module.

  • Connect a USB keyboard to X11.

  • Connect a power supply to the barrel jack X8. Attention: Double check that your power supply is within the Iris Carrier Board limits (7-27V) and that the polarity is not inverted. Also, make sure that the current capability of the power supply is enough, or the system may shut down unexpectedly. For evaluation purposes, a 12V 2A power supply is recommended.
