U-boot expects uImage format for the kernel image. In order for LTIB to generate a uImage file: $ export SYSCFG_KTARG=uImage $ ./ltib -p kernel Setup in U-Boot the kernel bootargs: u-boot> setenv bootargs noinitrd console=ttymxc0,115200 init=/linuxrc root=/dev/nfs nfsroot=10.29.244.27:/tftpboot/rootfs ip=dhcp Change 10.29.244.27 to your host IP. The procedure above is needed when default bootloader used by ltib was redboot. In some ltib releases (before 2010) default bootloader is u-boot. In this case, ltib will create uImage by default

There are two ways: 1. BitBake. Append the package into the IMAGE_INSTALL variable. But In case you want the package in every image,  add a line to your conf/local.conf file IMAGE_INSTALL_append = " package"           Make sure to include the space BEFORE the package name. You can add other packages, just place spaces in-between. In case you want the package in a particular image, e.g. fsl-image-gui,, add it on meta-fsl-demos/recipes-fsl/images/fsl-image-gui.bb IMAGE_INSTALL += " \     ${SOC_IMAGE_INSTALL} \     cpufrequtils \     nano \     packagegroup-fsl-gstreamer \     packagegroup-fsl-tools-testapps \     packagegroup-fsl-tools-benchmark \     packagegroup-qt-in-use-demos \     qt4-plugin-phonon-backend-gstreamer \     qt4-demos \     qt4-examples \     fsl-gui-extrafiles \     package \     " 2. Hob. Due to its graphical nature, adding more packages to a base image is easier than the bitbake way. Run the hob app under the build folder, select your machine and image, then edit the later (click on the Edit image button) In case the package is not available, you need to create it. As a starting point take a look at this example. In case you consider is good enough to be present on the mainstream repos, send the patch to the meta-freescale mailing list.

Changing Freescale's BSP U-boot using LTIB This quick recipe demonstrates how to compile U-boot using Freescale BSP. 0. After installing i.MX51 BSP: 1. Extract u-boot source: ./ltib -m prep -p u-boot 2. (optional) If you wish to apply changes to the code, the source is located at: <ltib path>/rpm/BUILD/u-boot-2009.08 3. Compile u-boot for the i.MX51 EVK ./ltib -m scbuilb -p u-boot 4. Copy the compiled file to a SD card on your host machine, insert the SD card and: $ sudo dd if=rpm/BUILD/u-boot-2009.08/u-boot.bin of=/dev/mmcblk0 bs=512 /dev/mmcblk0 should replaced according to your host, use "dmesg" after inserting the SD to find out where is the SD on your host. Unmount it before issuing the dd command.   5. Insert the SD on the i.MX 51 EVK, set the switches for SD Card boot and power on the board.

Q: To minimize i.MX6DL power consumption at stop mode, but needs i.MX6DL to wake-up by USB resume signal from Host PC. Can LDO_2P5(VDDHIGH_CAP) be powered off at stop mode in order to resume i.MX6DL by a USB resume signal that Host PC sends to i.MX6DL USBOTG(us as device mode only)? In other words, can USB OTG detect resume signal from Host PC and generate wakeup interrupt during stop mode with following LDO condition? -          LDO_USB is enabled and powered by USB_OTG_VBUS. -          LDO_2P5 is disabled during stop mode. -          LDO_1P1 is enabled during stop mode. The system uses LPDDR2, hence LDO_2P5 can be powered off at stop mode(I know this is not allowed for DDR3 as DDR IO need 2P5 as pre-driver). Actually tested on SDP, the system can not be resumed without LDO_2P5 as DDR IO need 2P5 for DDR3. A: Please note that disabling the LDO_2P5 supply, you are also disabling the DRAM, as the DRAM pre-drivers are powered by this supply(!). SDCKE is pulled down on the board, and it ensures that the DRAM is in proper state during DSM without LDO_2P5 power. we recommend to keep LDO_2P5 on at any mode(include DSM mode). ldo_2p5 is also one of power for USB phy.   4.3.2.2 LDO_2P5 The LDO_2P5 module implements a programmable linear-regulator function from VDD_HIGH_IN. The LDO_2P5 supplies the SATA Phy, USB Phy, LVDS Phy,   Actually I have tested on SDP, but we cannot resume the system without LDO_2P5 as DDR IO need 2P5 for DDR3.

Introduction The "smart" package management system is available in  Yocto Project for managing  packages on a target machine. A host is configured as a server for the packages and on the target the "package-management" feature is enabled for working with the packages. The steps for setup and usage are described below. Resources The Yocto Project package management system will work with many hosts and targets. The following were used for creating this document: Host: Ubuntu 14.04 64-bit Target: MCIMX6Q-SDP Freescale Yocto Project Release Documentation: Linux 3.14.38_6ul BSP & Multimedia Codecs Documentation (fsl-yocto-L3.14.38_6ul-ga.tar.gz) Host You have successfully installed a Freescale Yocto Project release. (Refer to Freescale Yocto Project Release Documentation). There are two steps for adding package management and then building: 1. Modify conf/local.conf EXTRA_IMAGE_FEATURES = "debug-tweaks package-management" ‍ 2. Build the image: bitbake core-image-minimal ‍ The core-image-minimal recipe provides an image enabling the target board to boot and support a serial console. 3. Create SDCARD: $ cd <build>/tmp/deploy/images/imx6qsabresd $ sudo dd if=core-image-minimal-imx6qsabresd.sdcard of=/dev/sdb bs=4M && sync ‍‍ Note - verify location of SDCARD on your host, /dev/sdb in this example. Examine 'cat /proc/partitions' 4. Setup web server and add link to rpm packages A web server, lighttpd, is installed. $ sudo apt-get install lighttpd ‍ Provide user write capability in /var/www $ sudo chmod 777 /var/www ‍ Create a soft link in the default web server directory to the rpm directory from the build. Note: Please update $HOME/<build> to your actual location: $ ln -s $HOME/<build>/tmp/deploy/rpm /var/www/imx6qsd ‍‍‍ Target Insert the SDCARD created from step 3 above, connect power and console cable  and power on the MCIMX6Q-SDP. Login using the "root" id, no password required. The /usr/bin/smart application is now used to setup the channels and perform package commands. For all smart options: smart --help ‍ 1. Add channels To add the packages from the host to your target, the smart  channel --add is used: Please enter the IP adress of your server, replacing SERVERIP below: smart channel --add all type=rpm-md name=all baseurl= http://SERVERIP/imx6qsd/all smart channel --add cortexa9hf_vfp_neon type=rpm-md name=cortexa9hf_vfp_neon baseurl= http://SERVERIP/imx6qsd/cortexa9hf_vfp_neon smart channel --add imx6qsabresd type=rpm-md name=imx6qsabresd baseurl= http://SERVERIP/imx6qsd/imx6qsabresd ‍‍‍‍‍‍‍‍‍ Check  the added channels: root@imx6qsabresd:~# smart channel --list all imx6qsabresd rpmsys cortexa9hf_vfp_neon ‍‍‍‍‍ 2. Update  local package cache Once the chanels have been added, the local package cache is updated. Note  SERVERIP below will be the host IP address in your network. root@imx6qsabresd:~# smart update Loading cache...

ro.hwui.disable_scissor_opt For Vivante GPU, the scissor should be enabled. The default value is enabled, So, keep the default value. ro.hwui.texture_cache_size ro.hwui.layer_cache_size ro.hwui.r_buffer_cache_size ro.hwui.path_cache_size ro.hwui.drop_shadow_cache_size These parameters depend on display resolution. The default value is calculated according to 720P resolution which near 1024x768 resolution on our platform. ro.hwui.text_small_cache_width ro.hwui.text_small_cache_height ro.hwui.text_large_cache_width ro.hwui.text_large_cache_height These variables depends on screen resolution, density(similar to ppi) and language used. On a larger resolution screen, there might be more characters painted on it. Better to have larger font cache size. On a larger density config, it tends to use larger fonts. If the language has more different characters (symbols), it may need larger texture size to cache the fonts. For example, English may only have 52 characters, but Chinese have more than 10K and each will occupy more memory cache than English character. If cache size is too small, performance may drop because the font renderer will flush existed cache and upload new ones. If cache size is too large, it just wastes memory. It's OK to flush existed cache sometimes. But it's better to have only one (or no) flush for rendering a single screen. The default value is optimum on out platform with 1024x768 display resolution. BTW, texture size limitation on current Vivante GPU are 8192 x 8192.

This is a HW design checklist for customer's reference. Please read and fill it in carefully before requesting a schematic review.

The Linux Kernel is just another recipe for Yocto, so learning to patch it you learn to patch any other package. In the other hand, Yocto **should not** be used for package development, but in those rare cases follow the below steps. It is assumed that you have already build the package you want to patch. 1. Create the patch or patches. In this example we are patching the Linux kernel for [wandboard-dual](http://www.wandboard.org/) machine; in other words, the value of MACHINE on the `build/conf/local.conf` is `MACHINE ??= 'wandboard-dual'`. In case you already have the patches, make sure these can be nicely applied with the commands `git apply --check <PATCH_NAME>`, and jump this step build $ cd tmp/work/wandboard_dual-poky-linux-gnueabi/linux-wandboard/3.0.35-r0/git build $ # Edit any files you want to change build $ git add <modified file 1> <modified file 2> .. # Select the files you want to commit build $ git commit -s -m '<your commit's title>' # Create the commit build $ git format-patch -1 # Create the patch 2. Create a new layer (see document i.MX Yocto Proyect: How can I create a new Layer?) 3. On the new layer (e.g `meta-fsl-custom`) , create the corresponding subfolders and the `.bbfile` sources $ mkdir -p meta-fsl-custom/recipes-kernel/linux/linux-wandboard-3.0.35/ sources $ cat > meta-fsl-custom/recipes-kernel/linux/linux-wandboard_3.0.35.bbappend FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:" SRC_URI += "file://0001-calibrate-Add-printk-example.patch" PRINC := "${@int(PRINC) + 1}" # SEE NOTE BELLOW ^d (The PRINC variable is not needed starting at Yocto 1.6 ([RFC] base.bbclass: Deprecate the PRINC logic - Patchwork)) 4. Move the patch to the new layer sources $ cp \ ../build/tmp/work/wandboard_dual-poky-linux-gnueabi/linux-wandboard/3.0.35-r0/git/0001-calibrate-Add-printk-example.patch \ meta-fsl-custom/recipes-kernel/linux/linux-wandboard-3.0.35 5. Setup the enviroment and clean previous package's build data (sstate) fsl-community-bsp $ . setup-environment build build $ bitbake -c cleansstate linux-wandboard 6. Compile and Deploy build $ bitbake -f -c compile linux-wandboard build $ bitbake -c deploy linux-wandboard 7. Insert the SD into your Host and copy the `uImage` into the first partition. Do not forget to unmount the partition before removing the card! build $ sudo cp tmp/deploy/images/uImage /media/Boot\ wandbo/ 8. Insert the SD into your board and test your change.

This document describes the i.MX 8MM EVK mini-SAS connectors features on Linux and Android use cases, covering the supported daughter cards, the process to change Device Tree (DTS) files or Boot images, and enable these different display options on the board.

It's the demo for hibernation for Android. Restore Android and UI can operate about 6 sec.

Hi all, I'm trying to port Android JB to a custom board based on imx6q. I'm not able to get the launcher. And even the display is shifting to right. The kernel i've tested with linux where the display is proper. Below is log. In the log Marked are the issues I'm facing. Any advice is helpful. I'm in very critical stage. Please help me to resolve this. I'm the source from android_jb4.2.2_1.0.0-ga_source bundle package. Uncompressing Linux... done, booting the kernel.

I'll update with the images(screenshots) soon. This document was generated from the following discussion: help in porting Android Jb to imx6q custom board

When using Gigabit Ethernet on boards i.MX running Windows 10 IoT Core users may experience network unstability and low latency using build W1809_1_1_0_imx-iotcore. This was fixed by increasing the size of Rx/Tx buffer in ethernet driver. Fix will be part of the next release of BSP, to apply fix to current version a patch was created. To apply patch, copy content of zip archive to appropriate location in folder structure and rebuild BSP.

Recipes to include Amazon's Alexa Voice Services in your applications. Step 1 : Get iMX Yocto AVS setup environment Review the steps under Chapter 3 of the i.MX_Yocto_Project_User'sGuide.pdf on the L4.X LINUX_DOCS to prepare your host machine. Including at least the following essential Yocto packages $ sudo apt-get install gawk wget git-core diffstat unzip texinfo \ gcc-multilib build-essential chrpath socat libsdl1.2-dev u-boot-tools Install the i.MX NXP AVS repo Create/Move to a directory where you want to install the AVS yocto build enviroment. Let's call this as <yocto_dir> $ cd <yocto_dir> $ repo init -u https://source.codeaurora.org/external/imxsupport/meta-avs-demos -b master -m imx-alexa-sdk-4.9.51-8mq_ga.xml Download the AVS BSP build environment: $ repo sync Step 2: Setup yocto for Alexa_SDK image with AVS-SETUP-DEMO script: Run the avs-setup-demo script as follows to setup your environment for the imx8mqevk board: $ MACHINE=imx8mqevk DISTRO=fsl-imx-xwayland source avs-setup-demo.sh -b <build_sdk_8M> Where <build_sdk> is the name you will give to your build folder. After acepting the EULA the script will prompt if you want to enable: Sound Card selection The following Sound Cards are supported on the build: 2-Mic Synaptics/Conexant 2-Mic TechNexion Voice Hat (with DSPConcepts SW) The script will prompt to select the soundcard you will be using: Which Sound Card are you going to use? Synaptics/Conexant .................... 1 VoiceHat (for DSPConcepts SW) ......... 2 Type the number of your selection and press Enter... Install Alexa SDK Next option is to select if you want to pre-install the AVS SDK software on the image. Do you want to build/include the AVS_SDK package on this image(Y/N)? If you select YES, then your image will contain the AVS SDK ready to use (after authentication). Note this AVS_SDK will not have WakeWord detection support, but it can be added on runtime. If your selection was NO, then you can always manually fetch and build the AVS_SDK on runtime. All the packages dependencies will be already there, so only fetching the AVS_SDK source code and building it is required. Finish avs-image configuration At the end you will see a text according with the configuration you select for your image build. Next is an example for a Preinstalled AVS_SDK with Synaptics Sound Card support ============================================================ AVS configuration is now ready at conf/local.conf - Sound Card = Synaptics - Alexa SDK 1.7 pre-installed - Wifi supported You are ready to bitbake your AVS demo image now:   bitbake avs-image If you want to use QT5DisplayCards, use then:   bitbake avs-image-qt5 ============================================================ Step 3: Build the AVS image Go to your <build_sdk> directory and start the build of the avs-image There are 2 options Regular Build: $ cd  <yocto_dir>/<build_sdk>   $ bitbake avs-image With QT5 support included: $ cd  <yocto_dir>/<build_sdk>   $ bitbake avs-image-qt5 The image with QT5 is useful if you want to add some GUI for example to render DisplayCards. Step 4 : Deploying the built images to SD/MMC card to boot on target board. After a build has succesfully completed, the created image resides at <build_sdk>/tmp/deploy/images/imx8mqevk/ In this directory, you will find imx8mqevk-avs--.sdcard image or imx8mqevk-avs-qt5--.sdcard, depending on the build you chose on Step3. To Flash the .sdcard image into an SD Card follow the next steps: Extract and copy the .sdcard file to your SD Card $ cd <build_sdk>/tmp/deploy/images/imx8mqevk/ $ cp -v imx8mqevk-avs-synaptics-1.7.sdcard.bz2 <workdir> $ cd <workdir> $ sudo bzip2 -d imx8mqevk-avs-synaptics-1.7.sdcard.bz2 $ sudo dd if=imx8mqevk-avs-synaptics-1.7.sdcard.bz2 of=/dev/sd<part> bs=1M && sync $ sync Properly eject the SD Card: $ sudo eject /dev/sd<part> Insert the flashed SD Card on the 8M EVK and boot. Follow the instructions at startup to setup your AVS and run the SampleApp. NXP Documentation For a more comprehensive understanding of Yocto, its features and setup; more image build and deployment options and customization, please take a look at the i.MX_Yocto_Project_User's_Guide.pdf document from the Linux documents bundle mentioned at the beginning of this document.
