2.2. Jumper
2.2.1. Jumper Description
Cards can configured by setting jumpers. A jumper is a metal bridge used to close
an electric circuit. It consists of two metal pins and a small metal clip (often
protected by a plastic cover) that slides over the pins to connect them. To close a
jumper, you connect the pins with the clip. To open a jumper, you remove the clip.
Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you
would connect either pins 1 and 2 or 2 and 3.
The jumper settings are schematically depicted in this manual as follows.
A pair of needle-nose pliers may be helpful when working with jumpers. If you
have any doubts about the best hardware configuration for your application,
contact your local distributor or sales representative before you make any
changes.
Generally, you simply need a standard cable to make most connections.
Warning!
To avoid damaging the computer, always turn off the power supply
before setting jumpers.

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. Setup Build Environment
This section explains how to set up the build environment, install and build, and set
up the host environment.
Note: If you need, more detailed instructions can be found at
L3.0.35_4.1.0_LINUX_DOCS in the file Setting_Up_LTIB_Host.pdf
(https://cache.freescale.com/secured/32bit/doc/support_info/L3.0.35_4.1.0_docs.tar.
gz?__gda__=1428423300_12712125f6c749dde454e0f5d9b338d5&fileExt=.gz)
3.2.1. Installing and build
Follow the steps below to preparing the build environment. Entering the command
without “$”.
# 0.1 pre-install
$ sudo apt-get install git u-boot-tools lzop
# 0.2 Cross Compiler As a result of the first two points, we now recommend these
simple steps to install a cross-compiler:
$ sudo apt-get install gcc-arm-linux-gnueabihf

20
# check gcc version
$ arm-linux-gnueabihf-gcc -v
# 0.3 add export to .bashrc
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
3.2.2. Download source code and checkout the latest version
# 1.1 u-boot source (u-boot-2009)
git clone https://github.com/embux/u-boot-imx.git u-boot-imx_2009
cd u-boot-imx_2009
git checkout imx_2009_ebx
# 1.2 Kernel source (imx_3.0.35)
$ git clone https://github.com/embux/linux-imx6.git
$ cd linux-imx6.git
$ git checkout imx_3.0.35_1.0.0_ebx
3.2.3. Build and Flashing the SD card
- u-boot
$make distclean
$make mx6dl_sabresd_config
$make
$ sudo dd if=u-boot.bin of=/dev/sdb bs=512 seek=2 skip=2 conv=fsync
- Kernel build and flash to SD Card (sdb, mounted /mnt)
$make clean
$make imx6_defconfig
$make -j4 uImage
