This post is about adding cellular modem support on the Boundary Devices i.MX6 boards under Ubuntu.  Many customers have requested cellular modem support on our i.MX6 boards (BD-SL-i.MX6, Nitrogen6X, Nitrogen6_Lite and Nitrogen6_MAX).  Since most cell modems are USB or PCIe devices, configuration is a software task, and mostly done in userspace. The steps are also different for Android, embedded Linux and desktop distributions.  In other words, its complicated. In this post, we’ll walk through all of the steps needed to configure a specific set of modems under Ubuntu as a reference. If you’re using another modem or another userspace, the details may be different, but the fundamentals will be the same. We used the Huawei E3131 USB dongle , and Huawei MU609 Mini-PCIe during this process, and will be adding them to our default kernels going forward. As you can see in this patch, we did have to add some USB device ids and make minor updates to the kernel as provided by the vendor. In the process, we should now also support the following Huawei models for various regions and carriers: MC323   CDMA: Downlink:153.6 kbps, Uplink: 153.6 kbps MU509   WDCMA: Downlink:3.6 Mbps, Uplink: 384 kbps MC509   EVDO: Downlink:3.1 Mbps, Uplink: 1.8 Mbps MU609   HSPA+: Downlink:14.4 Mbps, Uplink: 5.76 Mbps MU709   HSPA+: Downlink:21.6 Mbps, Uplink: 5.76 Mbps ME906   LTE: Downlink:100 Mbps, Uplink: 50 Mbps ME909   LTE: Downlink:100 Mbps, Uplink: 50 Mbps ME936   LTE: Downlink:100 Mbps, Uplink: 50 Mbps For more details including links to images as well as detailed descriptions on how to implement, please visit this blog post:  http://boundarydevices.com/cellular-modems-on-i-mx6-boards/

Now we are debugging audio quality with sgtl5000 on i.mx6DL platform. The test audio curve is attached, what we need now is to get 8dB more gain at 90Hz and 15dB more at 5KHz. Can anyone help on setting regs in sgtl5000 codec?How? Thanks in advance.

Introduction Currently there is not an easy procedure to build Qt 5.1 with hardware acceleration support for Freescale i.MX6 platform. This document describes the steps necessary to download all the prerequisite oftware, build Qt 5.1 code and examples, and verify the hardware acceleration support status. Required Software 1.     To start building, we need some development tools. This build is verified on LTIB (L3.0.35_4.0.0_130424_source.tar.gz downloaded from FreeScale website) and cross-compiled on a Ubuntu 12.04 64-bit PC. Verify that gpu-viv-bin-mx6q option is enabled in the LTIB configuration.                    $ mkdir -p ~/BSP                    $ cd ~/BSP                    $ tar -xzvf L3.0.35_4.0.0_130424_source.tar.gz   2.     Download Qt 5.1.1 source code from the Qt-project website. Create a build directory and extract the content in it.                    $ mkdir -p ~/Qt5                    $ cd ~/Qt5                    $ tar -xJvf qtbase-opensource-src-5.1.1.tar.xz Build procedure: 1.     Enter the Qt5 build directory and create a configuration script as follows:                   $ cd ~/Qt5/qt-everywhere-opensource-src-5.1.1/qtbase                   $ vi config.imx6                   #!/bin/sh                   ./configure -opensource -confirm-license -make libs -device imx6 \                   -device-option CROSS_COMPILE=\                   /opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- \                  -no-pch -no-opengl -no-icu                  -no-c++11 \                  -opengl es2 \                  -eglfs \                  -compile-examples \   2.     Edit the device configuration to specify the root file system of the BSP. Make sure the config file contains lines that match with what lists below                    $ cd ~/Qt5/qt-everywhere-opensource-src-5.1.1/qtbase/mkspecs/devices/linux-imx6-g++                    $ vi qmake.conf                    ROOTFS=/home/trainee/BSP/L3.0.35_4.0.0_130424_source/ltib/rootfs                    QMAKE_INCDIR           += $$ROOTFS/usr/include                    QMAKE_LIBDIR           += $$ROOTFS/usr/lib                    QMAKE_LFLAGS           += -Wl,-rpath-link,$$ROOTFS/usr/lib   3.     Run the configuration script and make sure that Qt5 has openGL ES 2.0 support when it is complete. Note that you must run 'make confclean' to remove the previous configuration when any hanges are made to the script.                 $ ./config.imx6                           This is the Qt Open Source Edition.                           You are licensed to use this software under the terms of  the Lesser GNU General Public License (LGPL) versions 2.1.                           You have already accepted the terms of the  license.                           Creating qmake...                            ….                            ….                            Support enabled for:                            Accessibility  .......... yes                            ….                            OpenGL .................. yes (OpenGL ES 2.x)                             ….                            Qt is now configured for building. Just run 'make'.             Once everything is built, you must run 'make install'.             Qt will be installed into             /home/trainee/BSP/L3.0.35_4.0.0_130424_source/ltib/rootfs/usr/local/Qt5.1.1             Prior to reconfiguration, make sure you remove any leftovers from             the previous build.   4.     Do a build. Note that all the libraries are copied to the appropriate directories in the root file system.                    $ make all -j8                    $INSTALL_ROOT=/home/trainee/BSP/L3.0.35_4.0.0_130424_source/ltib/rootfs/ sudo                    make install        5.     Build the examples                $ cd examples                $ make   6.     Copy an example (hellogl_es2) used to demonstrate openGL ES to the root file system.                $ sudo cp opengl/hellogl_es2/hellogl_es2                /home/trainee/BSP/L3.0.35_4.0.0_130424_source/ltib/rootfs/    Verify h/w acceleration support: 1.     Boot the board and verify that the galcore module is installed               $ cat /proc/devices | grep galcore               $ ls /dev/galcore   2.     Set up the required Qt environment               $ export QT_PLUGIN_PATH=/usr/local/Qt-5.1.1/plugins/        3.     Run the example. You shall see a rotating Qt logo on the display.               $ cd /               $ ./hellogl_es       4.     Run top command and it shows the application running with a very low (0 – 1 %) cpu usage.               $ top                 PID PPID USER     STAT   VSZ %VSZ CPU       %CPU COMMAND                                      2820 2809  root         S         188m 21.5   0              0.7       ./hellogl_es2 About Adeneo Embedded Adeneo Embedded provides system integration, design, support and training services to companies seeking world-class expertise in embedded solutions using high-performance architectures.

iWave has been one of the early adopters of i.MX6. As a result of this, iWave dived into the design and manufacture of one of the early i.MX6 Qseven System on Modules to keep up the commitment to clients. As recently Freescale has rolled out the Power Management Companion Chip for i.MX6, iWave has come up with the improved i.MX6 Qseven SOM integrated with PMIC to adhere to our corporate policy of constant improvement of design to meet customers’ needs. iWave is now happy to announce the launch of the new improved feature-rich i.MX6 Quad/Dual/Dual Lite/Solo Qseven SOM module with enhanced performance. Basically, the predecessor SOM is based on Qseven R1.2 specifications whereas the new SOM is compliant to Qseven R2.0 specifications. Freescale’s latest PMIC is integrated to the SOM for better power management. This feature enables various power management options to the customers including the dynamic voltage frequency scaling (DVFS) supported by the i.MX6 CPU. The new SOM is compliance to the latest R2.0 Qseven specification. The SOM supports 8 GPIOs on the LPC interface and additional UART port proposed in the latest R2.0 Qseven specification. These new SOMs will be supported with Linux, Android and Windows Embedded Compact 7 BSP. The SOMs will be software compatible with existing non-PMIC based i.MX6 Qseven SOMs with additional BSP patches. These new PMIC based SOMs and their associated heat spreader part samples are available for customer evaluation. For further information or inquiries please write to mktg@iwavesystems.com
