Getting Started with the DEV-IOT6U

This page outlines a basic guide to getting starting using the DEV-IOT6U.

• DEV-IOT6U Hardware Main Page

General Information

What Comes with the Development Kit

• SoM-IMX6U-120R2 (528MHz iMX6UL 4GB eMMC, 128MB SoM, connected to Carrier Board)
• SoM-112ES-131R1 (Dlx Carrier with Wifi/BT & Audio)
• 5V 3A Wall Power Supply
• 10 Pin Com to DB9 Cable 12"
• RJ45 to RJ45 Ethernet Cable 7'
• USB2.0A Male to Micro-USB Male 6'
• 2.4 & 5GHz 100mm Wifi Antenna
• MikroBus ROTARY B click

NOTE

Do to a design flaw in the MikroBus Rotary B Click, the card does not allow another SPI device to be present on the SPI Bus. The SoM-IMX6U uses the SPI Bus and the presence of MikroBus Rotary B Card prohibits the SOM from booting. To alleviate this issue, the pin labeled “SDO” must be cut and jumpers JB5 and JB6 on the Dev Kit Carrier Board (SoM-112) must be set to 3P3 (see figures below)

Tools Required

• Desktop PC (Linux or Virtual Linux Machine)
  • Instructions for Downloading a Virtual Machine with EMAC OE SDK pre-installed

Setup

1. Install EMAC OE SDK on your computer.

• Installation options are linked HERE.

2. Make the following cable connections using the cables provided:

• Board Micro-USB to USB Desktop
• Board Ethernet to Ethernet Network
• 5V Wall Power Supply to Board Power (may be left unplugged from wall until Step 3)

3. Open Minicom and create a terminal session with the DEV-IOT6U

• After supplying power, boot messages will be displayed followed by a log in prompt.
  • somimx6ul login: root
  • password: emac_inc
• Use command "ifconfig" in the terminal session to find the device's IP address that can be used during the development process.

Note: USB Port B (JK5) is disabled by default. Jumper JB9 must be in position B followed by command "gpioset gpiochip2 2=0" to enable. This disables the USB Port C (JK7) device port. Reverse the process with JB9 in position A followed by command "gpioset gpiochip2 2=1"

Development

There are two options in development with this device:
1. Using the EMAC OE SDK on terminal. [ Getting Started with the EMAC OE SDK ]
- or
2. Using the EMAC OE SDK on Qt Creator. [ Getting Started With Qt Creator ]

MikroBus Rotary B Click

EMAC has provided a MikroBus Rotary B Card which provide a number of LEDs and a Rotary Switch to allow for easy demonstration and interaction of the Eval Kit. Demo/Example Software is provided that interacts with this Card. This Software can be modified by the user as an exercise in using the development tools.

NOTE: Do to a design flaw in the MikroBus Rotary B Card which does not allow another SPI device to be present on the SPI Bus. The SoM-IMX6U uses the SPI Bus and the presence of MikroBus Rotary B Card prohibits the SOM from booting. To alleviate this issue, the pin labeled “SDO” must be cut and jumpers JB5 and JB6 on the Dev Kit Carrier Board (SoM-112) must be set to 3P3 (see figures below).
