Introduction EMV stands for Europay, MasterCard and VISA, and is a global standard for inter-operation of integrated circuit cards (ICC) and ICC reader terminals (like point of sale (POS) terminals, automated teller machines (ATMs)) for authenticating credit and debit payment cards transactions. Any IC card reader must be certified to be EMV compliant. The EMV standard defines the interaction at the physical, electrical, data and application levels between the IC cards and IC card terminal. For the contact smartcards it is based on standard ISO/IEC 7816. Some of the i.MX embeds a Subscriber Identification Module (SIM) which was designed to facilitate the communication to a mobile phone SIM card. It could be used to communicate indirectly with a banking smartcard due to the listed limitations in regards to the EMV requirements. Electrical Limitations The POS terminal must support 1.8V, 3.3V, and 5V smartcards. Depending on the i.MX, 1.8V or 3.3V could be supported but not both, and 5V is definitely out of the range of the I/O supplies. => a level adapter component is required between the i.MX and the smartcard. Protocol Limitations The communication between the IC card and the reader is asynchronous (almost a UART), but based on a common clock for synchronous operation. The ISO7816 standard defines the following: 1 ETU = F / D * 1 / f ETU is Elementary Time Unit, which is somehow the nominal time to transmit a bit (0 or 1). F or Fi is the clock rate conversion integer. D or Di is the baud rate adjustment integer. f is the frequency of the communication clock used between the controller and the smartcard. Below is a partial list of what the controller must support to pass the EMV certification, and the known limitations of the SIM controller: - baud rate at x1 (Fi/Di=372/1) => default speed for all smart cards =>  supported. - baud rate at x2 (Fi/Di=372/2 = 186/1) => a higher speed for some smart cards => not supported. - baud rate at x4 (Fi/Di=372/4 93/1) => a higher speed for some smart cards => not supported. - message length of 12ETU => specified for T=0 type smart card => supported. - error of -0.2ETU on message length of 12ETU => 11.8ETU smart card => not supported. - message length of 11ETU => specified for T=1 type smart card => supported. - error of -0.2ETU on message length of 11ETU => 10.8ETU smart card => not supported. Conclusion For these reasons, the i.MX SIM controller does not allow to pass the EMV certification without the usage of an external controller that must care of all these missing features. The SIM can still be used to communicate with that external controller such Atmel AT83C26, NXP TDA8023, Terridian, or On Semi. Freescale does not have driver neither reference design to support that configuration. This company has the expertise to work with EMV certification for the i.MX258 + a companion smartcard controller: http://www.alcineo.com

This example is useful  if you have your device connected to a host machine using a USB cable, and you want your host machine to be able to update your device using a protocol ready to go. Information you need prior to using this example Fastboot is a protocol used to update firmware in Android devices from a host over USB; Freescale implements fastboot as a uboot driver for the device and the implementation is available from patches applied to uboot source code; By default, fastboot is only enabled when building uboot to use with an Android BSP; To run fastboot at the device in default implementation you need to call it from uboot command line (using the debug serial port of the slave device, for example); The host fastboot application is available as source code from Google. You can build your own fastboot(.exe) binary (which is not in the scope of this howto), or you can find a binary ready for you to go searching the web; You are required to be familiar with Linux BSP and have i.MX53 BSP version 11.05 installed. With this information in mind, what do you get from this example? Patch for uboot to enable fastboot driver for iMX53 Quick Start Board with a new spec file; A command line application that set a flag in iMX53 to automatically start fastboot after a reset, either if it is a SOFT or a HARD reset. How to prepare the example Copy uboot patch file (attached) to /opt/freescale/pkgs; Replace your uboot spec file (u-boot.spec.in attached) in <bsp_root>/ltib/config/platform/imx/; Build a system image for iMX53 Quick Start Board with the packages you need; Build the command line application (setbootmode.c attached) using ltib shell; Prepare an SD card copy the command line application /usr/sbin in your SD card system partition. See attachment to this page. How to test the example Boot the Quick Start Board with the SD card you prepared; Login as root using a serial cable and a terminal application; Run setbootmode application as follows: $ setbootmode 1 Reboot the system: $ reboot After rebooting, the device will automatically run fastboot from uboot and will wait for a connection from the host machine. You can test the connection using a fastboot binary at the host machine (not provided here). Even if you HARD reset your hardware, your device will keep running fastboot at startup. If you want to go back to a regular boot operation, you need to cut power supply to your board. How does the magic happen? The setbootmode application sets the LSB in the Low Power General Register (LPGR) of the Secure Real Time Clock (SRTC) module to true. The patched version o uboot tests for this bit as a flag to run fastboot or not. The magic is that the LPGR is persistent, even during reset. Additional tips You can run setbootmode with no arguments to see its options; You need to set the boot mode to 0 after a successful update to avoid entering fastboot mode again after a new reboot; Partitioning of the device seen by fastboot is not implemented; Besides using setbootmode, you can read/set LPGR using either md.l / nm.l in uboot or devmem2 at command line: uboot-> md.l 0x53fa401c 1 - displays LPGR; uboot-> nm.l 0x53fa401c - presents a prompt for you to change LPGR; linux shell-> devmem2 0x53fa401c w - displays LPGR; linux shell-> devmem2 0x53fa401c w <value> - changes LPGR; devmem2 has issues that you need to fix so that you can use it to change LPGR: include "volatile" in all writing instruction; uncomment 'w' write instruction.

Graphics are a big topic in the Android platform, containing java/jni graphic framework and 2d/3d graphic engines (skia, OpenGL-ES, renderscript). This document describes the general Android graphic stack and UI features on Freescale devices. 1. Android Graphic Stacks All Android 3D apps and games have the following graphic stack: Android system UI and all Apps UI follow 2D graphic stack as below, the hardware render will accelerate Android 2D UI with GPU HW OpenGL-ES 2.0 to improve the whole UI performance. Hardware acceleration can be disabled on i.mx6 in device/fsl/imx6/soc/imx6dq.mk USE_OPENGL_RENDERER := false Then rebuild frameworks/base/core/jni, and replace libandroid_runtime.so Surfaceflinger is responsible of all surface layers composition, and  then generate the framebuffer pixmap for display devices. these graphic surface layers are from 2D/3D apps. Hwcomposer is the alternative module of Surfaceflinger with OpenGL-ES. Hwcomposer is used to combine the specific surface layers supported by specific vendor devices. Freescale i.MX6 devices use GPU 2D to combine most surface layers, and the system power can be reduced with GPU 2D instead of GPU 3D. The typical power saving case is video playback. Hwcomposer with GPU 2D can offload GPU 3D task when running game and benchmarks, it is proved to improve the overall system performance about 20%. 2. Performance measurment Show FPS for Android system performance For NFS boot you can set “debug.sf.showfps” to 1 in init.freescale.rc (“setprop debug.sf.showfps 1”) and then reboot the system. For SD or EMMC boot, you can issue command “setprop debug.sf.showfps 1” in console, then find system_server thread by top and kill it to reset the system. Graphic benchmarks for 3D capability measurement Quadrant Full test benchmark cover CPU, Memory, IO, 2D and 3D GLBenchmark http://www.glbenchmark.com/ NenaMark2 https://market.android.com/details?id=se.nena.nenamark2 An3DBench http://www.androidzoom.com/android_applications/tools/an3dbench_hnog.html AnTutu http://www.antutu.com/software.html 3DMark http://www.futuremark.com/benchmarks/3dmark06/introduction/ Browser benchmarks http://www.webkit.org/perf/sunspider/sunspider.html http://v8.googlecode.com/svn/data/benchmarks/current/run.html http://www.craftymind.com/guimark2/ http://www.craftymind.com/factory/guimark/GUIMark_HTML4.html http://themaninblue.com/writing/perspective/2010/03/22/ 3.  Android UI features Dual display with same content This feature is supported in the default image in Android i.MX 6 release package. In this feature, LVDS panel and HDMI output can be supported simultaneously. It is only enabled when the HDMI TV has been connected with the board. Overscan for TV devices Some TVs may miss display the contents in overscan area. To avoid the contents in overscan area being lost, the common implement is by underscanning with an adjustable black border and letitng the viewer adjust the width of the black border. The downscan operation is done by surfaceflinger when it does surface composition through HW OpenGL ES. There is no performance impact since all the work is done by GPU HW. Overscan can be configured in display setting in visual mode: 32 bits color depth 32bpp UI can be supported by adding “bpp=32” in uboot as below: setenv bootargs ‘… video=mxcdi1fb:RGB666,XGA,bpp=32 …’, also can configure it in display setting. Enable 32bpp frame buffer and application surface buffer will be allocate to RGBA8888 format instead of default RGB565 format, that means more system memory is allocated. After enabling 32bpp, if some applications still don't have better UI quality, check to see if  there is hard code to request RGB565 format surface (should request RGBA8888 format to get better quality). Sample code is attached to test for 32bpp (left is on 16bpp, right is on 32bpp) Display Visual Setting The display setting is the add-on feature in FSL Android release, it is very convenient for end-users to change display property, mostly for the following features: Dual display enablement Display color depth setting(16bpp, 32bpp) Overscan adjustment in horizontal and vertical orientation 4. Issue Diagnosis Application Compatibility Some Android applications may not run correctly on some Android releases. It may cause application compatibility, so check the application in other platforms. For example Neocore and Asphalt 5 can run on Eclair, Froyo, and Gingerbread, but will not correctly run on Honeycomb. GPU Compatibility Some game UIs may not correctly display on our Android release. When encountering this kind of issue, the customer can check whether it is caused by the game using an OpenGL extension which our GPU does not support. They can download another data package (for example not extension data package) to have a check. Others Enlarge GPU memory if you encounter UI abnormally displaying after running an application for a while. Some applications need Wifi connections, so monitor the console log to see whether there are any error reports.

Overview The purpose of this doument is to introduce how to enable PCIe WiFi into i.MX6 Android release. Environment Setup Hardware: i.MX6 SABRE-SD board Software: Android Jelly Bean 4.2 Software Configurations The source codes of Intel PCIe WiFi have been integrated for i.MX6 SABRE-SD board into i.MX6 Android release. However it's disabled by default. To enable it for i.MX6 SABRE-SD board, you can do the following: Change BOARD_WLAN_VENDOR to INTEL in device/fsl board configuration files.

** If you cannot access the www.youtube.com you may watch the Wi-Fi Display Sink Demo in here: ** ********      http://v.youku.com/v_show/id_XNzczMzQ2MTc2.html             ******** We already have the strong i.MX 6 to support the Android kitkat now. So we also develop the WiFi Display Sink in it. With Wi-FI Display technology we can cast the screen and audio to another one via Wi-Fi P2p. It's also named the Miracast. Freescale extends Android by offering a Wi-Fi Display Sink feature. The Wi-Fi hardware module used for this feature are the Realtek RTL8821AS , RTL8723AS and AR6233 SDIO Cards. But the design of this feature allows porting to any Wi-Fi hardware module. Using the Freescale Wi-Fi Display Sink API and the demonstration application, users can easily develop their own Sink Application. This feature has been verified using several of the most popular Android phones and tablets. Our Wi-Fi Display has the following highlight feature: Low latency Support UIBC (When Source device uses Freescale Android maddev_kk4.4.3-2.0.0) Rapid recovery from network congestion Compatibility to different vendor Wi-Fi chips and Wi-Fi Display devices From the demo video we can cast the stopwatch and measure the latency by it. Here are the high quality video shots and we can calculate the real latency which less than 200ms!      For the WiFi Display Spec the orange ones in below figure were achieved in our WiFi Display.

Some processor’s GPIO settings on the i.MX Pins Tool version 7 may not show allow to select direction and just show an option “Input/Output” as shown. This will be fixed, but the settings can be changed on the local processor data as a workaround. For more information and documentation for the Pins Tool for i.MX please visit its home page on the link below: https://www.nxp.com/design/designs/pins-tool-for-i-mx-application-processors:PINS-TOOL-IMX   First, find where the Pins Tool data package is stored. To do this open the Pins Tool and click Help > About. On the About screen click the Details button. Take also note of the name of the package that needs to be fixed.   Go to the location where the data package is stored and find the processor data. The file that would need to be updated is signal_configuration.xml    Find the GPIO pin data and change the directions from the string ““inOut”to the string “in out”. Then save this file.    Close and reopen the Pins Tool. The direction on the updated package should now show the options Input and Output.

You already know. Your source code is one week old now, so please, update it (or should I say 'sync' it?)! Get used to update your BSP layers. Recipe Is the name of file that determinates how a package should act. For example, the version, where it is the mainstream repo, how to build, install, link. etc. Kernel For meta-fsl-arm the kernel recipes are under meta-fsl-arm/recipes-kernel/linux (take a look here meta-fsl-arm - Layer containing Freescale ARM hardware support metadata) For meta-fsl-arm, there are 3 kernel recipes: linux-fslc_3.8.bb  --> kernel mainline (from kernel.org) linux-imx_2.6.35.3.bb  --> kernel from FSL, for imx5x and imx28 linux-imx_3.0.35.bb --> kernel from FSL for imx6 Take the linux-imx for imx6 as an example meta-fsl-arm - Layer containing Freescale ARM hardware support metadata The recipe determinates: what´s the compatible machine for this linux version (mx6) what´s the commit ID for the head of this code (SRCREV) (MX6DL and MX6SL have different source code) what´s the patches for the mx6 boards (SRC_URI). In order to see where the source code is cloned from, you need to go to .inc file meta-fsl-arm - Layer containing Freescale ARM hardware support metadata SRC_URI = "git://git.freescale.com/imx/linux-2.6-imx.git \            file://defconfig \ " it´s from git.freescale.com. In addition, there is a defconfig file added on SRC_URI. There is a defconfig file for every board, on every Linux revision. Some defconfigs are shared for more than one board (for example, every mx6 board), and some Linux version are not compatible for some boards (for example, imx53 is only compatible with 2.6.35). During a bitbake linux-imx, a temp folder will be created under build/tmp/armv7-imx6....../linux-imx, with code from git, patches and defconfig. Then bitbake takes that defconfig and configure the kernel, built it, and deploy it. So, in order to change the kernel configuration (make menuconfig) you must replace your defconfig file from meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6 How to change kernel configuration Create the new defconfig Copy it to meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6 (or the right folder for your board/kernel) $ bitbake -c cleansstate linux-imx $ bitbake linux-imx (if you want only the kernel image) $ bitbake fsl-image-gui (if you want to generate a complete image using the new kernel) How to make menuconfig with yocto $ bitbake -c menuconfig linux-imx will generate a config file on tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.0.35-r33.10/git/.config The complete step by step to change the kernel configuration $ bitbake -c menuconfig linux-imx (change anything) $ cp tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.0.35-r33.10/git/.config ../sources/meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6/defconfig $ bitbake -c cleansstate linux-imx $ bitbake fsl-image-gui The uImage will be under tmp/deploy/image In order to replace only uImage binary into one ready sdcard: $sudo cp tmp/deploy/image/uImage-imx6-XXX.bin /media/user/Boot imx6/uImage Kernel Mainline - kernel.org In order to use kernel mainline instead of linux-imx. Please add the following code to your conf/local.conf PREFERRED_PROVIDER_virtual/kernel = "linux-fslc" Make sure the desired board is supported by kernel.org. In order to take and build kernel mainline manually, please see https://community.freescale.com/docs/DOC-95017 Final points It´s not a simple task, I know. Yocto is not the best tool for use to develop and customize kernel during development stage. It is easier to use an external toolchain (bitbake meta-toolchain). Once the kernel development, or customization, is done, the changes can be integrated in the Yocto so it is managed for production use. I like to have a copy of kernel source code cloned on my machine directly from git.freescale.com, then I can re-configure it, rebuild it, apply some patches, make changes, and build it manually - any way I want it. So, I only change kernel using yocto when I know the bug and I know how to fix it, and I have the patch. (and this is the way I like to work) Although this is how to configure (and even patch) kernel (if you want to patch kernel, follow the example in the recipes) If you face any error, please, let me know. I tested the steps and it worked, but I´m using an Ubuntu machine, not a virtual machine (and I´m not sure how -c menuconfig will act in a virtual machine). Go to Yocto Training - HOME Go to Task #4 - Deploy and test

1. To setup the Yocto environment, from the BASE folder run fsl-community-bsp $ . setup-environment build 2. Build the toolchain build $ bitbake meta-toolchain # Other toolchains: # Qt Embedded toolchain build: bitbake meta-toolchain-qte # Qt X11 toolchain build: bitbake meta-toolchain-qt 3. Install it on your PC build $ sudo sh \   tmp/deploy/sdk/poky-eglibc-x86_64-arm-toolchain-<version>.sh 4. Setup the toolchain environment build $ source \   /opt/poky/<version>/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi 5. Get the Linux Kernel's source code. $ git clone git://git.freescale.com/imx/linux-2.6-imx.git linux-imx $ cd linux-imx 6. Create a local branch linux-imx $ BRANCH=imx_3.0.35_4.0.0 # Change to any branch you want,   # Use 'git branch -a' to list all linux-imx $ git checkout -b ${BRANCH} origin/${BRANCH} 7. Export ARCH and CROSS_COMPILE linux-imx $ export ARCH=arm  linux-imx $ export CROSS_COMPILE=arm-poky-linux-gnueabi- linux-imx $ unset LDFLAGS 8. Choose configuration and compile linux-imx $ make imx6_defconfig  linux-imx $ make uImage  9. To Test your changes, copy the `uImage` into your SD Card linux-imx $ sudo cp arch/arm/boot/uImage /media/boot 10. If case you want your changes to be reflected on your Yocto Framework, create the patches following the document i.MX Yocto Project: How can I patch the kernel?

Introduction The Intel® Neural Compute Stick 2 (Intel® NCS 2) is Intel’s newest deep learning inference development kit. Packed in an affordable USB-stick form factor, the Intel® NCS 2 is powered by latest VPU (vision processing unit) – the Intel® Movidius™ Myriad X, which includes an on-chip neural network accelerator called the Neural Compute Engine. With 16 SHAVE cores and a dedicated hardware neural network accelerator, the NCS 2 offers up to 8x performance improvement+ over the previous generation. Ref: https://software.intel.com/en-us/articles/run-intel-openvino-models-on-intel-neural-compute-stick-2   The NCS 2 officially supported hardware platform is x86 PC and Raspberry Pi. In this guide, we will introduce how to implement in i.MX8MQ. Please see attached guide for more details.

The attched package includes mbedTLS and DCP/RNGB driver based on SDK2.2, you can apply it on Windows Installer: MCUXpresso SDK2.2 for i.MX 6ULL 1. fsl_dcp.c/fsl_dcp.h and fsl_rngb.c/fsl_rngb.h under devices\MCIMX6Y2\drivers is dcp ang rngb driver. 2. Some files under middleware\mbedtls-2.4.0\port\sdk are porting code for mbedTLS 3. Example codes are under folder boards\evkmcimx6ull which have driver example and mbedTLS example. 4, The patch package only support IAR toolchain. 5, Due to SDK don't support allocation of non-cachable memory dynamically, so some static non-cachable bufferes in sdk_mbedtls.c is used for shared memory with hareware. So mbedTLS don't be used for multi-thread concurrently.
