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.

TFTP     TFTP service will be used to transfer the kernel image from host to target every time the system reboots. Select the Linux distribution: All Boards TFTP Fedora All Boards TFTP on OpenSuse All Boards TFTP on Ubuntu

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.

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.

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.

The i.MX21ADS board needs a flash programmer software called iMX21ADS_TOOLKIT or just HAB. This programmer evolved to current ATK. You can download iMX21ADS_TOOLKIT here.  

1. INTRODUCTION:      This document explains the general and basic steps to customize U-Boot for your own board. The board used in this document it is a working and stable board, the UDOO board (http://udoo.org). 2. REQUIREMENTS:     Install Yocto Project. See the Freescale Yocto Project User's Guide.     Generate and install the meta-toolchain. Follow this great training to do so  Yocto Training - HOME     Generate core-image-minimal of L3.14.28 of FSL BSP obtained from https://www.freescale.com/webapp/Download?colCode=L3.14.28_1.0.0_iMX6QDLS_BUNDLE&appType=license&location=null&Parent_no…   3. ADDING i.MX6 CUSTOM BOARD SUPPORT FOR U-BOOT.     This section follows the steps found in Chapter 1 of the i.MX6 BSP Porting Guide of the Yocto documentation (L3.14.28) https://www.freescale.com/webapp/Download?colCode=L3.14.28_1.0.0_LINUX_DOCS&location=null&fpsp=1&WT_TYPE=Supporting%20In… . Obtain U-Boot Source Code. After having installed Yocto project and generate a valid imx6 image, the U-Boot code should be located at <build directory>/tmp/work/<machine>-poky-linuxgnueabi/u-boot-imx/<version>/git. Prepare the Code. Choose a board as reference, this board should be as similar as possible to your custom board. Copy the board directory :                $ cp -R board/freescale/mx6sabresd/ board/freescale/mx6_udoo Copy the existing mx6sabresd.h configuration file as mx6_udoo.h                $ cp include/configs/mx6sabresd.h include/configs/mx6_udoo.h Create one entry in boards.cfg. Add a configuration entry in the boards.cfg file. Active  arm  armv7  mx6  freescale  mx6_udoo mx6_udoo mx6_udoo:IMX_CONFIG=board/freescale/mx6_udoo/mx6dl_4x_mt41j128.cfg,MX6Q,DEFAULT_FDT_FILE="imx6q-udoo.dtb",DDR_MB=1024 Rename <board>.c file. Rename board/freescale/mx6sabresd/mx6sabresd.c   to   board/freescale/mx6_udoo/mx6_udoo.c Modify Makefile. Change the line of COBJS to your custom board at  board/freescale/mx6_udoo/:      obj-y  := mx6sabresd.o Create a Shell script. Create a script to compile your new configuration. The script for this example is shown below and its name is build_u-boot.sh: #!/bin/bash export ARCH=arm export CROSS_COMPILE=/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- make distclean; make mx6_udoo_config make Run the script to verify if the new configuration is correct.      $./build_u-boot.sh 4. CUSTOMIZING BOARD CODE      The fist part to customize is the DCD table. The DCD table contains configuration data for the DDR controller and memory. The DCD is read by the BootROM code in the iMX family and executed before copying the Uboot image to DDR. The DCD is built in the .cfg file pointed in the new entry we just added in the boards.cfg file (mx6dl_4x_mt41j128.cfg). Below you can find an example of the data that can be found in this file: /* * Device Configuration Data (DCD) * * Each entry must have the format: * Addr-type           Address        Value * * where: *      Addr-type register length (1,2 or 4 bytes) *      Address   absolute address of the register *      value     value to be stored in the register */ DATA 4, 0x020e0774, 0x000C0000 DATA 4, 0x020e0754, 0x00000000 DATA 4, 0x020e04ac, 0x00000030 DATA 4, 0x020e04b0, 0x00000030 DATA 4, 0x020e0464, 0x00000030 DATA 4, 0x020e0490, 0x00000030 DATA 4, 0x020e074c, 0x00000030 DATA 4, 0x020e0494, 0x00000030 DATA 4, 0x020e04a0, 0x00000000 The .cfg files used in this example were taken from an old U-Boot version (2009) non dtb capable. The used files are found in the attached .zip file. The specific initialization code for each board is found in mx6<customer board>.c in board/freescale/mx6<customer board>.c  in this case board/freescale/mx6_udoo/mx6_udoo.c file. Below it is explained the needed changes to route the serial console to the correct UART module, disable an external watchdog, configure and initialize the Ethernet PHY, change the lvds clock and configure the correct USDHC module.        U-Boot calls already defined functions from a function pointer array that takes care of the board initialization at different stages. For example the board_early_init_f() is called at an        early phase where we can disable the wdog and initialize the uart pins; board_init() and board_late_init() are called after board_early_init_f(). The UDOO board features an external watchdog that needs to be disabled with a GPIO, otherwise U-Boot resets after a few seconds:          The WDOG pins need to be configured and in the mx6_udoo.c file a global struct configuration for those pins is declared, as well as macros for each pin #define WDT_EN  IMX_GPIO_NR(5, 4) #define WDT_TRG IMX_GPIO_NR(3, 19) iomux_v3_cfg_t const wdog_pads[] = {         MX6_PAD_EIM_A24__GPIO5_IO04 | MUX_PAD_CTRL(NO_PAD_CTRL),         MX6_PAD_EIM_D19__GPIO3_IO19, }; static void setup_iomux_wdog(void) {         imx_iomux_v3_setup_multiple_pads(wdog_pads, ARRAY_SIZE(wdog_pads));         gpio_direction_output(WDT_TRG, 0);         gpio_direction_output(WDT_EN, 1);         gpio_direction_input(WDT_TRG); } This configuration needs to be called at some point of the board_early_init_f() int board_early_init_f(void) {         setup_iomux_wdog();         This way the board_early_init_f() calls the iomux for the external wdog and disables it. The UART console is routed to UART2, EIM_D26/UART2_TXD and EIM_D27/UART2_RXD. A different structure is defined with the pin configuration for the UART2.      iomux_v3_cfg_t const uart2_pads[] = {         MX6_PAD_EIM_D26__UART2_TX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),         MX6_PAD_EIM_D27__UART2_RX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL), }; This configuration should be called at early stage too. static void setup_iomux_uart(void) {         imx_iomux_v3_setup_multiple_pads(uart2_pads, ARRAY_SIZE(uart2_pads)); } int board_early_init_f(void) {         setup_iomux_wdog();         setup_iomux_uart(); Also the UART BASE register has to be defined as well as the console device. This is defined in the include/configs/mx6_udoo.h file. #define CONFIG_MXC_UART_BASE   UART2_BASE #define CONFIG_CONSOLE_DEV      "ttymxc1" The UDOO board features only one micro SD slot to boot and U-Boot environment storage. It uses only 4 bits and it has to be configured too. In the include/configs/mx6_udoo.h file the USDHC module has to be defined and the MMC environment device. #define CONFIG_SYS_FSL_USDHC_NUM   3 #define CONFIG_SYS_MMC_ENV_DEV       0     /* SDHC3 */          The USDHC3 pin configuration has to be defined:      iomux_v3_cfg_t const usdhc3_pads[] = {         MX6_PAD_SD3_CLK__SD3_CLK   | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_SD3_CMD__SD3_CMD   | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_SD3_DAT0__SD3_DATA0 | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_SD3_DAT1__SD3_DATA1 | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_SD3_DAT2__SD3_DATA2 | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_SD3_DAT3__SD3_DATA3 | MUX_PAD_CTRL(USDHC_PAD_CTRL),         MX6_PAD_NANDF_D0__GPIO2_IO00    | MUX_PAD_CTRL(NO_PAD_CTRL), /* CD */ }; struct fsl_esdhc_cfg usdhc_cfg[1] = {         {USDHC3_BASE_ADDR, 0, 4}, }; This must be called and configured from the board_mmc_init() function: int board_mmc_init(bd_t *bis) {         s32 status = 0;         imx_iomux_v3_setup_multiple_pads(         usdhc3_pads, ARRAY_SIZE(usdhc3_pads));         usdhc_cfg[0].sdhc_clk = mxc_get_clock(MXC_ESDHC3_CLK);                 status |= fsl_esdhc_initialize(bis, &usdhc_cfg[0]);         return status; } The Ethernet PHY is configured in the board_eth_init() function. This function should initialize the pins for the external ethernet phy, mdio and phy configuration.  Just a piece of code is shown below: iomux_v3_cfg_t const enet_pads1[] = {         MX6_PAD_ENET_MDIO__ENET_MDIO            | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_ENET_MDC__ENET_MDC              | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TXC__RGMII_TXC       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TD0__RGMII_TD0       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TD1__RGMII_TD1       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TD2__RGMII_TD2       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TD3__RGMII_TD3       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_TX_CTL__RGMII_TX_CTL      | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_ENET_REF_CLK__ENET_TX_CLK       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_RXC__RGMII_RXC       | MUX_PAD_CTRL(ENET_PAD_CTRL),         /* RGMII reset */         MX6_PAD_EIM_D23__GPIO3_IO23              | MUX_PAD_CTRL(NO_PAD_CTRL),         /* alimentazione ethernet*/         MX6_PAD_EIM_EB3__GPIO2_IO31              | MUX_PAD_CTRL(NO_PAD_CTRL),         /* pin 32 - 1 - (MODE0) all */         MX6_PAD_RGMII_RD0__GPIO6_IO25            | MUX_PAD_CTRL(NO_PAD_CTRL),         /* pin 31 - 1 - (MODE1) all */         MX6_PAD_RGMII_RD1__GPIO6_IO27            | MUX_PAD_CTRL(NO_PAD_CTRL),         /* pin 28 - 1 - (MODE2) all */         MX6_PAD_RGMII_RD2__GPIO6_IO28            | MUX_PAD_CTRL(NO_PAD_CTRL),         /* pin 27 - 1 - (MODE3) all */         MX6_PAD_RGMII_RD3__GPIO6_IO29            | MUX_PAD_CTRL(NO_PAD_CTRL),         /* pin 33 - 1 - (CLK125_EN) 125Mhz clockout enabled */         MX6_PAD_RGMII_RX_CTL__GPIO6_IO24         | MUX_PAD_CTRL(NO_PAD_CTRL), }; static iomux_v3_cfg_t const enet_pads2[] = {         MX6_PAD_RGMII_RD0__RGMII_RD0       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_RD1__RGMII_RD1       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_RD2__RGMII_RD2       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_RD3__RGMII_RD3       | MUX_PAD_CTRL(ENET_PAD_CTRL),         MX6_PAD_RGMII_RX_CTL__RGMII_RX_CTL      | MUX_PAD_CTRL(ENET_PAD_CTRL), }; static void setup_iomux_enet(void) {         imx_iomux_v3_setup_multiple_pads(enet_pads1, ARRAY_SIZE(enet_pads1));         udelay(20);         gpio_direction_output(IMX_GPIO_NR(2, 31), 1); /* Power on enet */         gpio_direction_output(IMX_GPIO_NR(3, 23), 0); /* assert PHY rst */         gpio_direction_output(IMX_GPIO_NR(6, 24), 1);         gpio_direction_output(IMX_GPIO_NR(6, 25), 1);         gpio_direction_output(IMX_GPIO_NR(6, 27), 1);         gpio_direction_output(IMX_GPIO_NR(6, 28), 1);         gpio_direction_output(IMX_GPIO_NR(6, 29), 1);         udelay(1000);         gpio_set_value(IMX_GPIO_NR(3, 23), 1); /* deassert PHY rst */         /* Need delay 100ms to exit from reset. */         udelay(1000 * 100);         gpio_free(IMX_GPIO_NR(6, 24));         gpio_free(IMX_GPIO_NR(6, 25));         gpio_free(IMX_GPIO_NR(6, 27));         gpio_free(IMX_GPIO_NR(6, 28));         gpio_free(IMX_GPIO_NR(6, 29));         imx_iomux_v3_setup_multiple_pads(enet_pads2, ARRAY_SIZE(enet_pads2)); }           Let's notice that the external PHY is not the same as the SABRESD AR8031. The UDOO features the MICREL KSZ9031 PHY. The latter needs to be defined and the former undefined in the include/configs/mx6_udoo.h file. #undef  CONFIG_PHY_ATHEROS #define CONFIG_PHY_MICREL #define CONFIG_PHY_MICREL_KSZ9031 Besides the PHY address has to be changed. #define CONFIG_FEC_MXC_PHYADDR  6 At this point, the serial console, SD card saving arguments and ethernet should be working. The last point is to configure the LVDS display. The LVDS display of the UDOO board is connected in the same port as the SABRE-SD board, but the operation frequency is different and it has to be modified to work at ~ 33.26MHz for the 7 inches LVDS display.      The mx6_udoo.c file contains a setup_display function that configures the LDB module. This functions is called in the board_early_init_f(). With the current clock configuration is not possible to get  the 33.2MHz for the LVDS and a different clock source for the LDB module must be chosen. The backlight and lvds power signals must be on.           The current configuration uses the mmdc_ch1 clock and to get closer to 33.26MHz the PLL2_PFD0 is chosen.        gpio_direction_output(IMX_GPIO_NR(1, 2), 1); /* LVDS power On */         gpio_direction_output(IMX_GPIO_NR(1, 4), 1); /* LVDS backlight On */         imx_iomux_v3_setup_multiple_pads(di0_pads, ARRAY_SIZE(di0_pads));         enable_ipu_clock();         imx_setup_hdmi();         /* Turn on4LDB0, LDB1, IPU,IPU DI0 clocks */         reg = readl(&mxc_ccm->CCGR3);         reg |=  MXC_CCM_CCGR3_LDB_DI0_MASK | MXC_CCM_CCGR3_LDB_DI1_MASK;         writel(reg, &mxc_ccm->CCGR3);         /* set LDB0, LDB1 clk select to 011/011 */         reg = readl(&mxc_ccm->cs2cdr);         reg &= ~(MXC_CCM_CS2CDR_LDB_DI0_CLK_SEL_MASK                  | MXC_CCM_CS2CDR_LDB_DI1_CLK_SEL_MASK);         reg |= (1 << MXC_CCM_CS2CDR_LDB_DI0_CLK_SEL_OFFSET)               | (1 << MXC_CCM_CS2CDR_LDB_DI1_CLK_SEL_OFFSET);         writel(reg, &mxc_ccm->cs2cdr); With this changes you can compile the new U-Boot image with ./build_u-boot.sh and then just copy the uboot.imx file to your sd: # sudo cp if=uboot.imx of=/dev/sdX bs=512 seek= 2 && sync 5. TESTING YOUR CHANGES Inser the sd with the U-Boot image to micro sd slot and power up the board. You should get the U-Boot serial console like shown below. In the console you can test the ethernet and phy configuration with the PING command: I hope you find these basic steps useful for different boards.

In order to create this Ogg Theora encoder example you need to add libogg, libvorbis and libtheora to your system. Download these libs from http://www.theora.org/downloads/ : libogg-1.1.3, libvorbis-1.2.0 and libtheora-1.0.tar.bz2 Copy them to /opt/ltib/pkgs Create the directories ltib/dist/lfs-5.1/libogg, ltib/dist/lfs-5.1/libvorbis, ltib/dist-5.1/lfs/libtheora. Copy these spec files to its respective directories: File:Libogg.gz File:Libvorbis.gz File:Libtheora.gz Execute this sequence to compile and install these libs: $ ./ltib -p libogg.spec -m prep $ ./ltib -p libogg.spec -m scbuild $ ./ltib -p libogg.spec -m scdeploy $ ./ltib -p libvorbis.spec -m prep $ ./ltib -p libvorbis.spec -m scbuild $ ./ltib -p libvorbis.spec -m scdeploy $ ./ltib -p libtheora.spec -m prep $ ./ltib -p libtheora.spec -m scbuild $ ./ltib -p libtheora.spec -m scdeploy Now download and compile yuv2theora.c encoder example: File:Yuv2theora.gz $ ./ltib -m shell LTIB> gcc yuv2theora.c -o yuv2theora `pkg-config --libs --cflags theora` In this example we used a video sample (YUV420) on CIF format: http://140.116.72.80/~jhlin5/ns2/yuv_to_avi/paris_cif.yuv Update: All these libraries were added on LTIB Savannah CVS, then you just need to use them and compile the above code.

These days I supported a customer to enable LVDS in function. The data format between external LVDS in chip and i.MX6 CSI is RGB565, with HSYNC and VSYNC signals available. So we take gated mode configuration for i.MX6 CSI. Customer environment:  i.MX6 D  + Linux LTIB 4.0.0 BSP By default,  RGB565 gated mode is not supported by Linux LTIB 4.0.0 V4L2 capture driver, here is a summary for what we need to change for the driver to support RGB565 gated mode. Please apply the attached patch "0001-ENGR00262270-IPU3-Basic-16-bit-generic-data-support.patch". By this patch, IPU_PIX_FMT_GENERIC_16 can be supported by ipu3 driver. For V4L2 capture setup, file linux-3.0.35/drivers/media/video/mxc/capture/mxc_v4l2_capture.c,  function mxc_v4l2_s_fmt(), add code segment like this:                  switch(f->fmt.pix.pixelformat) {                  ............................................................................                  case V4L2_PIX_FMT_SGRBG8:                           size = f->fmt.pix.width * f->fmt.pix.height * 2;                           bytesperline = f->fmt.pix.width * 2;                           break;                  default:                           break;                  }                  Also for file linux-3.0.35/drivers/media/video/mxc/capture/ipu_csi_enc.c,  function csi_enc_setup(), please add code segment:                  else if (cam->v2f.fmt.pix.pixelformat == V4L2_PIX_FMT_SGRBG8)                            pixel_fmt = IPU_PIX_FMT_GENERIC_16;           By the modifications above, IPU_PIX_FMT_GENERIC_16 can be set for the CSI IDMAC channel. For sensor driver, please set pixel format to IPU_PIX_FMT_GENERIC_16 Don't forget to set GATED MODE and data with to 16 bits for CSI param in file linux-3.0.35/drivers/media/video/capture/mxc_v4l2_capture.c, function mxc_v4l2_s_param                 csi_param.clk_mode = IPU_CSI_CLK_MODE_GATED_CLK;                 csi_param.data_width = IPU_CSI_DATA_WIDTH_16; Please ensure CSI->MEM IDMAC channel should be choosed      The key point is that for CSI RGB565 gated mode support, the pixel format for IDMAC channel should be set to GENERIC 16, and for CSI port configuration, the pixel format is BAYER mode.
