B digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This device generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communication. However, there is no guarantee
that interference will not occur in a particular in a particular installation. If this
device does cause harmful interference to radio or television reception, which
can be determined by turning the device off and on, the user is encouraged to try
to correct the interference by one or more of following measures:
Reorient or relocate the receiving antenna
Increase the separation between the device and receiver
Connect the device into an outlet on a circuit different from that to which
receiver is connected
Consult the dealer or an experienced radio/TV technician for help

Software User Guide
This chapter details the Linux operation on ICM-2010.

3. Software User Guide
3.1. Introduction
This chapter details the Linux operation on ICM-2010 platform. This platform is an
embedded system with Linux kernel 3.0.35. It contains all system-required shell
commands and drivers ready. You can evaluate and develop under Ubuntu 12.04 LTS
environment.
There are three major boot components for Linux, “u-boot.bin”, “uImage” and “root
file system”. The “u-boot.bin” is for initializing peripheral hardware parameters; the
“uIm- age” is the Linux kernel image and the “File System” is for Linux O.S. used.
It will not be able to boot into Linux environment successfully if one of above three
files is missing from booting media (in ICM-2010, we use SD/MMC card)
3.2. Create SD/MMC Card using Linux Host
3.2.1. Requirements
An SD/MMC card reader, like a USB card reader, is required. It will be used to
transfer the boot loader and kernel images to initialize the partition table and copy
the root file system. To simplify the instructions, it is assumed that a 4GB SD/MMC
card is used.
Any Linux distribution can be used for the following procedure. It is recommended to
use a Linux distribution that LTIB has been tested against such as Ubuntu 9.04.
The Linux kernel running on the Linux host will assign a device node to the SD/MMC
card reader. The kernel might decide the device node name or udev rules might be
used. In the following instructions, it is assumed that udev is not used.
To identify the device node assigned to the SD/MMC card, enter the command:
$ cat /proc/partitions
major minor #blocks name
8 0 175825944 sda
8 1 254976 sda
8 2 1 sda
8 5 175567872 sda
8 0 7761920 sdb
8 0 2048000 sdb
In this example, the device node assigned is /dev/sdb (a block is 512B large).

19
Download the u-boot & Kernel Images for ICM-2010 SD card image: go to
https://github.com/embux/ , and choose the right image for your platform (in this case: ICM-
2010-images.tar.gz). Extract the file for preparing the SD/MMC images download.
3.2.2. SD/MMC Partitions
The layout of the MMC/SD/TF card for Android system is shown below:
Model: Generic- SD/MMC (scsi)
Disk /dev/sdc: 7884MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
No. Name Size Type File-System
1 rootfs 7.3G primary ext4
2 recovery 32MB primary ext4
3 1K extended
5 1KB logical
6 1MB logical
7 1MB logical
8 1MB logical
9 storage 500MB logical fat16
10 env 90MB logical fat16
In order to create the SD card, the partition table must be created. If a partition
already exists and it is big enough for the file system you want to deploy, then you
can skip this step.
Below is a partition example for partition 1 (rootfs).
To create a partition, at offset 32768 (in sectors of 512 bytes) enter the following
command:
$ sudo fdisk /dev/sdb
Note: On most Linux host operating systems, SD card will be mounted automatically
upon insertion. Therefore, before running fdisk, please make sure that SD card is
unmounted (via 'sudo umount /dev/sdb').
Type the following parameters (each followed by <ENTER>):

20
u [switch the unit to sectors instead of cylinders]
d [repeat this until no partition is reported by the ‘p’ command ]
n [create a new partition]
p [create a primary partition]
1 [the firs partition]
32768 [start at offset sector #32768, i.e. 16MB, which leaves enough space for the
kernel, the boot loader and its configuration data]
<enter> [using the default value will create a partition that spans to the last sector
of the medium]
w [this writes the partition table to the medium and fdisk exits]
Use the commands above to create rest 9 partitions to complete the partition table.
3.2.3. Copying the Boot loader Image
Once the partition table is ready, enter the following command to copy the U-Boot
image to the SD/MMC card:
$ sudo dd if=u-boot.imx of=/dev/sdb bs=1k seek=1 conv=fsync
3.2.4. Copying the Kernel Image and Device Tree Files
The following command will copy the kernel image and device tree files to the
SD/MMC card:
$ sudo mount –t vfat /dev/sdb10 /home/user/mountpoint
$ cp uImage /home/user/mountpoint
$ cp boot-env /home/user/mountpoint
$ cp imx6dl-embux-icm2010.dtb /home/user/mountpoint
$ sync
$ sudo umount /home/user/mountpoint
3.2.5. Copying the Root File System (rootfs)
The file system format ext3 or ext4 is a good option for removable media due to the
built- in journaling. Run the following command to format the partition:
$ sudo mkfs.ext3 /dev/sdb1
Or
$ sudo mkfs.ext4 /dev/sdb1
Copy the target file system to the partition:
