Contents
Introduction
This article provides an installation guide for Linux kernel and Debian root file system on the IOT-GATE-iMX7 Internet of Things Gateway and SBC-IOT-iMX7 Internet of Things Single Board Computer eMMC internal storage device.
Preparation steps
- Obtain a PC workstation with a USB port.
- Download the Linux package for IOT-GATE-iMX7 and SBC-IOT-iMX7 from CompuLab website. Use either IOT-GATE-iMX7 or SBC-IOT-iMX7 product web page for downloading. Unzip the package to a directory on your host workstation.
- All image files mentioned below can be found in the images subdirectory.
- Use the standard microUSB-to-USB cable to connect the host PC to the micro USB connector marked Console on IOT-GATE-iMX7 rear panel (connector P3 on SBC-IOT-iMX7).
- Make sure the new /dev/ttyUSBx device file is created by using the ls /dev/ttyUSB* command. x is the last number of the ttyUSB device.
Preparing installation media
- Obtain a micro SD card. Any commercially available micro SD card of 1GB (or larger) may be used.
- Create a first partition on it. The partition can be formatted either ext2/3/4 or FAT file system.
- Copy all files found in the directory images from the unzipped Linux package to the first partition on the installation media (micro SD card).
