This section provides information on jumper settings and
connectors on the IBR115 in order to set up a workable system.
The topics covered are:
• M.2 card Installation
• Jumper and connector locations
• Jumper settings and information of connectors

IBR115 User’s Manual
2.1 M.2 Card Installation
To install the NGFF M.2 card, locate the slot on the board and perform the
following steps.
(This is illustrated by the example of M.2 Type 2280)
1. Align the key of the M.2 card to the interface, and insert the card
slantwise.
2. Push the M.2 card down, fix it onto the brass standoff with a screw.

2.2 Setting the Jumpers
Set up and configure your IBR115 by using jumpers for various settings and
features according to your needs and applications. Contact your supplier if
you have doubts about the best configuration for your use.
2.2.1 How to Set Jumpers
Jumpers are short-length conductors consisting of several metal pins with a
non-conductive base mounted on the circuit board. Jumper caps are used to
have the functions and features enabled or disabled. If a jumper has 3 pins,
you can connect either PIN1 to PIN2 or PIN2 to PIN3 by shorting.

When two pins of a jumper are encased in a jumper cap, this jumper is
closed, i.e. turned On.
When a jumper cap is removed from two jumper pins, this jumper is open,
i.e. turned Off.

IBR115 User’s Manual
3.1 Make a Recovery MicroSD Card
Note: This is for advanced users who has IBASE standard image file only.
Basically, IBR115 is preloaded with O.S (Android / Linux) into eMMC by
default. Connect the TFT-LCD with IBR115 (or HDMI), and 12V power
directly.
This chapter guides you to make a recovery boot-up microSD card. IBASE
optionally provides 7” /15” LVDS panel and HDMI display for you to prepare
the software application pre-development easily under Linux platform.
3.1.1 Preparing the Recovery MicroSD card to Install
Linux/ Android image into eMMC
Note: All data in the eMMC will be erased.
1. System requirements: ubuntu12.04 or over; microSD card: 4GB or
greater in size.
2. Login with root
3. Decompress ibr115_make_fs.tar.bz2.
tar jxvf ibr115_make_fs.tar.bz2
4. Enter ibr115_make_fs directories
cd ibr115_make_fs
5. Copy new firmware version (eg. 20150814-111827) into
ibr115_make_fs.
cp $(direction to release)/20150814-111827 . –rf
6. Confirm the name of the microSD card device used for the upgrade.
6-A. Check the partition of the current system.

3. It takes about 15 minutes. After 10 minutes, the screen goes into sleep.
When the upgrade is finished, the screen will automatically open. Do
not power off.

UPGRADE END Please power down and pull out microSD" indicates
the installation is successfully completed.
5. Power down and pull out microSD.
3.2 Display Parameter Setting in Kernel
IBR115 supports LVDS 15” output by default.
1. If you use HDMI to display, run the command
/home/root/display_config/config_displag_mode.sh 1
2. If you use LVDS 7” to display, run the command
/home/root/display_config/config_displag_mode.sh 2
3. If you use LVDS 15” to display, run the command
/home/root/display_config/config_displag_mode.sh 3

4.1 Building BSP Source
4.1.1 Preparation
The suggested Host platform is Ubuntu 12.04 and 14.04 in x86 and x64
versions.
1. Install necessary packages before building:
sudo apt-get install gawk wget Git-core diffstat unzip texinfo
sudo apt-get install gcc-multilib build-essential chrpath socat
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git
sudo apt-get install texinfo
2. Decompress the IBR115 source file ibr115.tar.xz into "/home/" folder.
4.1.2 Installing Toolchain
Decompress Toolchain poky.tar into directory "/opt".
4.1.3 Building U-Boot
cd /home/ibr115
cd
ibr115-x11/tmp/work/imx6dlsabresd-poky-linux-gnueabi/u-boot-imx/2016.03-r0/git
source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
make mx6dlsabresd_defconfig
make
4.1.4 Building Kernel
cd /home/ibr115
cd
ibr115-x11/tmp/work/imx6dlsabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/git
source
/opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
make imx_v7_defconfig
make zImage LOADADDR=0x10008000
make imx6dl-sabresd.dtb

IBR115 User’s Manual
4.1.5 Building RAMdisk Image (Optional)
1. Enter IBR115.
cd /home/ibr115
2. Running the script below.
./build.sh ibr115
3. See the image in the "release" directory.
ls release/ibr115-20170519-030011/
rootfs.tar.bz2 u-boot-imx6dlsabresd.imx zImage zImage-imx6dl-sabresd.dtb
4.1.6 Install Linux to MicroSD Card
1. Refer to the section 3.1 Make a Recovery MicroSD Card in chapter 3.
2. Run the make card script below.
./make_sd.sh /dev/sdd 20150814-111827
3. The appearance of the sentence "SD card for booting create done"
indicates the installation is successfully done.
4. Pull out the microSD card
4.1.7 Booting with Your MicroSD Card
Insert the microSD card to your board and insert special COM port dongle to
boot from microSD. Connect a debug cable to debug port with serial port
115200/N/8/1 setting on your PC’s serial port program, such as
hyperterminal/teraterm. Connect LVDS 15” display panel. Power on and you
will see U-Boot prompt.
If you want to change to another monitor (or display panel) type, refer to the
section 3.2 Display Parameter Setting in Kernel to set video output
command.

E. MicroSD Card Test
When IBR115 is booted from eMMC, microSD card is “/dev/mmcblk1” and
able to see by “ls /dev/mmcblk1*” command:
/dev/mmcblk1 /dev/mmcblk1p2 /dev/mmcblk1p4 /dev/mmcblk1p5
/dev/mmcblk1p6
When booting from microSD card, replace test pattern “/dev/mmcblk1” to
“/dev/mmcblk0”.
Note: This operation may damage the data stored the microSD card. Before
starting the test, make sure there is no critical data in the eMMC flash
being used.
• Read, write, and check
SD_DIR="/run/media/mmcblk1"
#create data file
dd if=/dev/urandom of=/var/data1 bs=1024k count=100
#write data to SD card
dd if=/var/data1 of=$ SD_DIR/data2 bs=1024k count=100
