3. Thermal Considerations
The main processor on the Z3-DM8148-MOD-2X generates a large amount of heat, and is cooled by a heat
sink. The heat sink may reach temperatures in excess of 75°C during operation. Please make sure that the
airflow for the heat sink is free and unimpeded at all times. Hot air must have a place to escape to allow
for room air to be used to cool the chip. Failure to do so may result in permanent damage to the processor.
The maximum continuous power consumption by the whole Z3-DM8148-MOD-2X system during normal
operation should be less than 18W, with up to 12W dissipated by the main processor. Please plan the
cooling strategy appropriately.

4. Untarring and Building the Sample Code
4.1 Preparing the Linux Environment
Prior to building the Z3 sample code, certain modules are required. In Ubuntu 10.x, the following
command can be used to get the required modules:
sudo apt-get install bison flex mtd-utils liblzo2-dev uuid-dev zlib1g-dev
libpcre3-dev autoconf autoconf-archive automake automake1.9 automake1.9-doc
libtool libtool-doc
In Fedora, the command would be:
sudo yum install bison flex mtd-utils mtd-utils-ubi lzo-devel libuuid-devel
pcre-devel automake automake17 automake14 autoconf libtool
If you are running a 64-bit OS, it may be necessary to install some 32-bit libraries for the cross-compiling
toolchain. You can determine whether your OS is 64-bit by using the “uname –p” command. A 64-bit OS
will return “x86_64,” while a 32-bit OS will return “i386”, “i586”, or “i686”.
For 64-bit Ubuntu, you can get the necessary libraries by typing:
# sudo apt-get install ia32-libs
For 64-bit Fedora, you can type:
# sudo yum install glibc.i686
4.2 Making the Directories and Running the Make Script
The software provided will allow you to re-create the pre-installed software of the DM8148-MC-RPS starting
from the included source code.
On a PC running Linux, create a directory where the released materials are going to be located:
# mkdir /home/z3/z3-dm814x
Copy the released tar archive to that directory:
# cp SW-5R1-00055-01_DM8148-MC-RPS-20130820.tar.bz2 /home/z3/z3-dm814x
Untar the archive:
# tar -xvjf SW-5R1-00055-01_DM8148-MC-RPS-20130820.tar.bz2
Note: Untarring could take 5 to 10 minutes.
Then go into the directory just created and run the build script:
# cd z3-centaurus-dm814x_MC-RPS-20130819
# ./makeall
Note: Building can take around 30-40 minutes. You will also need to type in the sudo password a few
times throughout the build.

The outcome of the build process should be newly created image files in the images directory. You can
confirm this by doing the following:
# cd images
# ls -alt
The result should be something like the following. Note that actual filenames, dates, and times will differ.

5. Code Overview
Once you have untarred the code, you will see the following top-level directories:
build-tools Config files and scripts for building the codebase
dvr-rdk A modified version of the TI RDK code
factory Factory testing scripts (the user can disregard these)
filesys The base filesystem for release
kernels Kernel code for release
sysapps Various supporting applications
toolchain The ARM toolchain for building the codebase
u-boot u-boot code for release
z3apps Z3 demo application code and scripts
The Z3 demo code that comes with the Z3-DM8148-MC-RPS is run from the run.sh script in dvr-
rdk/dvr_rdk/bin/ti814x. This code calls the z3_dvr_rdk_demo_mcfw_api.out binary, which initializes and
runs the encoder. This binary is built from the dvr-rdk directory. The code for the binary resides in
z3apps/rdk/rdk_demo. The z3apps/rdk directory is described in more detail in the next section.
5.1 The z3apps/rdk directory
There are 3 main subdirectories: rdk_demo, z3_mcfw_api, and z3
5.1.1 rdk_demo
This directory contains the code for the various modes that Z3’s boards are able to run in. The encoder
setup is done in demo_vcap_vdis.c. The decoder setup is done in demo_vdec_vdis.c. The passthrough
setup is done in demo_vcap_vdis.c.
The file demo_rtptx.c is responsible for setting the output mode of the encoder. Output to file, rtp, and
MPEG2-TS are handled here.
The file demo_mcsenc.c contains the implementation of the command line interface. This can be run
using the following command:
# source /opt/mcsenc/mcsenc.sh

5.1.2 z3_mcfw_api
This directory contains a modified version of the TI mcfw api (found in dvr-
rdk/dvr_rdk/mcfw/src_linux/mcfw_api) that is tailored to work with Z3’s hardware and use-cases. The
link setup code for Z3’s demos can be found in the usecases directory. The use-case code is called from
ti_vsys.c in the same directory.
5.1.3 z3
This directory contains the base code for rtp tx and rx, as well as the base code for audio capture and
output.
5.2 RDK documentation

(2) Connect the supplied 2.5mm serial cable and NULL modem adapter to your PC.
(3) Take the HDMI cable connected to the monitor and connect it to HDMI In 1 of the board.
(4) Connect the Ethernet
The next step is to set up a terminal to view the activity of the board …
6.3 Set up the Terminal Window
(5) If you are running from a Windows PC, run TeraTerm. Select “Setup – Serial Port” and set the
following:
Port: Whichever serial port the port is connected to
Baud Rate: 115200
Data: 8-bit
Parity: None
Stop: 1-bit
Flow Control: None
(6) If you are running from Linux, type:
# sudo minicom –s
And then configure by doing the following:
-Select “Serial Port Setup”
-Ensure the right Serial Device is specified (typically “/dev/ttyUSB0”)
-Set option E (“Bps/Par/Bits”) to 115200 8N1

6.4 Power on the board
(7) Connect the 12V power supply and turn on the switch. If all is configured properly, you should see the
board booting up within the terminal window. After about a minute, you will see the RPS Main Menu:
Note the local IP address and netmask (in this example, it is 192.168.81.48 and 255.255.0.0). This is the IP
address of the board. You will need this later to access the web interface.

6.5 Ensure your PC has a proper IP address
(8) To be able to communicate with the board, the PC that you are communicating from needs to have at
least the same first 2 parts of the IP address. For example, if the board has an IP address of
192.168.81.48, your PC would need to have an address of 192.168.x.y, where y is anything but 48 (and
not conflicting with whatever is on your current network, of course). Ensure that this is the case. If
necessary, use the “P” and “N” options in the RPS menu to modify the address / network mask of the
board to conform to your network. Note that the first 2 parts being the same are based on a netmask
of 255.255.0.0. If netmask were 255.255.255.0, then the first 3 parts of the IP address would have to
be the same.
After you are done, make note of the address you set your PC to. This will be important in the
streaming step.
6.6 Run the Web Interface to Configure CH1
