HARMAN_STCT_IOG1_USER_GUIDE Rev. C1 Certification FCC CE FCC Statement This equipment has been tested and found to comply with the limits for a Class 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 equipment 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 communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ‐Reorient or relocate the receiving antenna. ‐Increase the separation between the equipment and receiver. ‐Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. ‐Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. (Example‐ use only shielded interface cables when connecting to computer or peripheral devices) FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled Environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This transmitter must not be co‐located or operating in conjunction with any other Antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co‐located or operating in conjunction with any other antenna or transmitter. This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Caution! The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user authority to operate the equipment. ... -

Page 9: Bringup Procedures
HARMAN_STCT_IOG1_USER_GUIDE Rev. C1 2 Bringup Procedures The board can be booted in 2 modes 1. USB boot mode 2. SPI boot mode Boot mode is selected by the headers H1 and H2. If user need usb boot mode he need to place jumpers on both H1 and H2 headers. If no jumpers are placed on H1 and H2 the board will be in SPI boot mode. -

Need to be run on command prompt root@imx6slevk:~#, ln –sf /bin/login /usr/bin/login chmod 777 –R zigbee/ 3.5 jffs2 Partition In SPI flash there are a 41MB jffs2 partition which can be used as storage for files. And file will be present there on every boot till then we delete those from jffs2 partition. - Page 18 HARMAN_STCT_IOG1_USER_GUIDE Rev. C1 gawk, wget, git-core, diffstat, unzip, texinfo, gcc-multilib, build-essential, chrpath, libsdl1.2-dev, apt-file 1. Go to source/yocto directory cd source/yocto/ 2. Give command MACHINE=imx6slzbha source ./setup-environment build This command sets the build environment and automatically you will be moved to build directory.
- Page 19 HARMAN_STCT_IOG1_USER_GUIDE Rev. C1 Steps are as follows 1.Go to directory tools 2. you create a directory called ramdisk in the directory tools. 3. untar the filesystem image to this ramdisk folder using the command sudo tar -xjf ../source/yocto/build/tmp/deploy/images/imx6slzbha/core-image-minimal- imx6slzbha.tar.bz2 -C ramdisk/ 4.Run command sh create_ramdisk.sh 5.
