I have finally been able to get multi MSI (not MSI-X) working on the i.MX6 using the Linux kernel v4.1.15 release supported by Freescale/NXP. Attached are four patches which will need to be applied. This has been tested with two different end point FPGA devices with the i.MX6 running in root complex, I can confirm that multi MSI is now working.   Freescale/NXP: Please put these patches in your supported main line so others can have native multi MSI support.   You may have to contact your board manufacturer to find where within Yocto you will need to store these patches. If just building the kernel outside of Yocto then you can directly apply them.   The four kernel (v4.1.15) files which need to be patched are: <kernel source path>/include/linux/msi.h <kernel source path>/drivers/pci/msi.c <kernel source path>/drivers/pci/host/pcie-designware.h <kernel source path>/drivers/pci/host/pcie-designware.c   Once the above patches are applied and you create a new image/build you can start using the multi MSI APIs in your driver and pci_msi_vec_count() and pci_enable_msi_range() will work; this assumes your end point device on the PCIe link is working correctly.   Hopefully this is helpful to those who need multi MSI.   This document was generated from the following discussion: SOLVED: i.MX6 and Multi MSI Working

Host TFTP and NFS Configuration Now configure the Trivial File Transfer Protocol (TFTP) server and Networked File System (NFS) server. U-Boot will download the Linux kernel and dtb file using tftp and then the kernel will mount (via NFS) its root file system on the computer hard drive. 1. TFTP Setup   1.1.1 Prepare the TFTP Service   Get the required software if not already set up. On host for TFTP: Install TFTP on Host $ sudo apt-get install tftpd-hpa   (Note: There are a number of examples in various forums, etc, of how to automatically start the TFTP service - but not all are successful on all Linux distro's it seems! The following may work for you.)   Start the tftpd-hpa service automatically by adding a command to /etc/rc.local. $ vi /etc/rc.local   Now, just before the exit 0 line edit below command then Save and Exit. $ service tftpd-hpa start  Now, To control the TFTP service from the command line use: $ service tftpd-hpa restart    To check the status of the TFTP service from the command line use: $ service tftpd-hpa status   1.1.1 Setup the TFTP Directories Now, we have to create the directory which will contain the kernel image and the device tree blob file. $ mkdir -p /imx-boot/imx6q-sabre/tftp Then, copy the kernel image and the device tree blob file in this directory. $ cp {YOCTO_BUILD_DIR}/tmp/deploy/images/{TARGET}/zImage /imx-boot/imx6q-sabre/tftp $ cp {YOCTO_BUILD_DIR}/tmp/deploy/images/{TARGET}/<dtb file> /imx-boot/imx6q-sabre/tftp   OR we can use the default directory created by yocto {YOCTO_BUILD_DIR}/tmp/deploy/images/{TARGET}/ The tftpd-hpa service looks for requested files under /imx-boot/imx6q-sabre/tftp The default tftpd-hpa directory may vary with distribution/release, but it is specified in the configuration file: /etc/default/tfptd-hpa. We have to change this default directory with our directory   Edit default tftp directory $ vi /etc/default/tftpd-hpa   Now, change the directory defined as TFTP_DIRECTORY with your host system directory which contains kernel and device tree blob file. Using created directory TFTP_DIRECTORY=”/imx-boot/imx6q-sabre/tftp” OR Using Yocto directory path TFTP_DIRECTORY=”{YOCTO_BUILD_DIR}/tmp/deploy/images/{TARGET}” Restart the TFTP service if required $ service tftpd-hpa restart   1.2 NFS Setup 1.2.1 Prepare the NFS Service Get the required software if not already set up. On host for NFS: Install NFS on Host $ sudo apt-get install nfs-kernel-server The NFS service starts automatically. To control NFS services : $ service nfs-kernel-server restart To check the status of the NFS service from the command line : $ service nfs-kernel-server status 1.2.2 Setup the NFS Directories Now, we have to create the directory which will contain the root file system. $ mkdir -p /imx-boot/imx6q-sabre/nfs   Then, copy the rootfs in this directory. $ cp -R {YOCTO_BUILD_DIR}/tmp/work/{TARGET}-poky-linux-gnueabi/{IMAGE}/1.0-r0/rootfs/* /imx-boot/imx6q-sabre/nfs   OR we can use the default directory created by yocto. $ {YOCTO_BUILD_DIR}/tmp/work/{TARGET}-poky-linux-gnueabi/{IMAGE}/1.0-r0/rootfs 1.2.3 Update NFS Export File The NFS server requires /etc/exports to be configured correctly to access NFS filesystem directory to specific hosts. $ vi /etc/exports Then, edit below line into the opened file. <”YOUR NFS DIRECTORY”> <YOUR BOARD IP>(rw,sync,no_root_squash,no_subtree_check) Ex. If you created custom directory for NFS then, /imx-boot/imx6q-sabre/nfs <YOUR BOARD IP>(rw,sync,no_root_squash,no_subtree_check) Ex: /imx-boot/imx6q-sabre/nfs 192.168.*.*(rw,sync,no_root_squash,no_subtree_check) OR /{YOCTO_BUILD_DIR}/tmp/work/{TARGET}-poky-linux-gnueabi/{IMAGE}/1.0-r0/rootfs <YOUR BOARD IP>(rw,sync,no_root_squash,no_subtree_check)   Now, we need to restart the NFS service. $ service nfs-kernel-server restart   2 Target Setup   We need to set up the network IP address of our target. Power On the board and hit a key to stop the U-Boot from continuing. Set the below parameters, setenv serverip 192.168.0.206       //This must be your Host IP address The path where the rootfs is placed in our host has to be indicated in the U-Boot, Ex. // if you choose default folder created by YOCTO setenv nfsroot /{YOCTO_BUILD_DIR}/tmp/work/{TARGET}-poky-linux-gnueabi/{IMAGE}/1.0-r0/rootfs   OR // if you create custom directory for NFS setenv nfsroot /imx-boot/imx6q-sabre/nfs Now, we have to set kernel image name and device tree blob file name in the u-boot, setenv image < zImage name > setenv fdt_file <dtb file name on host> Now, set the bootargs for the kernel boot, setenv netargs 'setenv bootargs console=${console},${baudrate} ${smp} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp' Use printenv command and check loadaddr and fdt_addr environment variables variables for I.MX6Q SABRE, loadaddr=0x12000000 fdt_addr=0x18000000   Also, check netboot environment variable. It should be like below, netboot=echo Booting from net ...; run netargs; if test ${ip_dyn} = yes; then setenv get_cmd dhcp; else setenv get_cmd tftp; fi; ${get_cmd} ${image}; if test ${boot_fdt} = yes || test ${boot_fdt} = try; then if ${get_cmd} ${fdt_addr} ${fdt_file}; then bootz ${loadaddr} - ${fdt_addr}; else if test ${boot_fdt} = try; then bootz; else echo WARN: Cannot load the DT; fi; fi; else bootz; fi; Now, set environment variable bootcmd to boot every time from the network, setenv bootcmd run netboot Now finally save those variable in u-boot: saveenv Reset your board; it should now boot from the network: U-Boot 2016.03-imx_v2016.03_4.1.15_2.0.0_ga+ga57b13b (Apr 17 2018 - 17:13:43 +0530)  (..)

As of this writing, April 2015, the default sdcard image created from a Yocto Project build has all the software images nicely aligned to create a SDCARD. 10/7/2020: Update - SDCARD image names have been updated to images ending with .wic as the default from Yocto Project.  The process is the same for both .sdcard and .wic files.   There are two partitions within the image: A W95 FAT32 (LBA) partition that contains the Linux zImage, and various device tree binary (dtb) files A Linux root file system. Each partition can be mounted from your Linux host computer, then you can read or write the partition contents. Here are the steps based on the core-image-base recipe for the imx6sxsabresd machine using Yocto Project release L3.14.28_1.0.0_GA.   The name of the image: core-image-base-imx6sxsabresd.sdcard Run the fdisk command to view the contents of the image: $ fdisk -l core-image-base-imx6sxsabresd.sdcard Disk core-image-base-imx6sxsabresd.sdcard: 100 MB, 100663296 bytes 4 heads, 32 sectors/track, 1536 cylinders, total 196608 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00074663 Device Boot Start End Blocks Id System core-image-base-imx6sxsabresd.sdcard1 8192 24575 8192 c W95 FAT32 (LBA) core-image-base-imx6sxsabresd.sdcard2 24576 188415 81920 83 Linux   Determine the byte offset into the sdcard image of where each partition starts:  core-image-base-imx6sxsabresd.sdcard1 starts at sector 8192. One sector unit is 512 bytes.                8192 * 512 = 4194304 core-image-base-imx6sxsabresd.sdcard2 starts at sector 24576. 24576 * 512 = 12582912   Mount Partitions First create mount points: $ sudo mkdir /mnt/{mp1,mp2}    sdcard1 partition $ sudo mount -o loop,offset=4194304 core-image-base-imx6sxsabresd.sdcard /mnt/mp1 NOTE: An alternate method for determining the offset, see below: $ sudo mount -o loop,offset=$((512 * 8192)) core-image-base-imx6sxsabresd.sdcard /mnt/mp1 sdcard2 partition $ sudo mount -o loop,offset=12582912 core-image-base-imx6sxsabresd.sdcard /mnt/mp2 View the contents of each mounted partition $ ls /mnt/mp1 imx6sx-sdb.dtb imx6sx-sdb-lcdif1.dtb imx6sx-sdb-reva.dtb imx6sx-sdb-sai.dtb imx6sx-sdb-emmc.dtb imx6sx-sdb-m4.dtb imx6sx-sdb-reva-ldo.dtb zImage $ ls /mnt/mp2 bin boot dev etc home lib lost+found media mnt proc run sbin sys tmp usr var   When done release the mount points and remove them from /mnt $ sudo umount /mnt/{mp1,mp2} $ sudo rm /mnt/{mp1,mp2}  

About this document This document describe the setup detail for Interfacing, Installing, programming (basis) and testing depth cameras with MX6QDL based boards using Ubuntu as rootfs on i.MX6 processors boards. Supported NXP HW boards: i.MX 6QuadPlus SABRE-SD Board and Platform i.MX 6Quad SABRE-SD Board and Platform i.MX 6DualLite SABRE-SD Board i.MX 6Quad SABRE-AI Board i.MX 6DualLite SABRE-AI Board Depth sensors tested: Microsoft Kinect, ASUS Xtion. Prime Sense Carmine Software:   Gcc, Ubuntu 14.04v,  Openni, Python, ROS. 1. Depth Sensor Depth sensors are 3D vision sensors, mainly used in 3D vision application and motion gaming and robotics. For this paper we are going to use Kinect sensor and Asus Xtion connection to i.MX6 Processor boards and will get 3D images that are converted to finer points called point cloud. a) Microsoft Kinect Kinect mainly has an IR camera, IR projector and RGB camera, the IR and projector generates the 3D point cloud of the surroundings. It also has a mic array and motorized tilt for moving up and down. Kinect reveal that both the video and depth sensor cameras have a 640 x 480-pixel resolution and run at 30 FPS (frames per second). The RGB camera capture 2D color images, whereas the depth camera captures monochrome depth images. Kinect has a depth sensing range from 0.8mts to 3.5 mts b) Asus Xtion: Another alternative to kinect is Asus Xtion Pro.  Is a 3D sensor designed for motion sensing applications, this sensor is only for 3D sensing and it doesn’t have sound sensing. It has an infrared projector and a monochrome CMOS sensor to capture the infrared data. Xtion can be powered from USB itself and can calculate a sense depth from 0.8mts to 3.5 mts from the sensor. c) Prime Sense Carmine: The Prime Sense team (apple bought this company in November 2013) developed the Microsoft Kinect 3D vision, later develop their own 3D vision sensor Carmine. It also works with IR projector, RGB CMOS sensor and a depth CMOS sensor. All sensor are interfaced in System On Chip and is powered trough USB. Carmine capture 640x480 at 30 FPS and can sense from 0.35 mts to 3 mts. Developers can program the device using OpenNI and its wrapper libraries. All these sensors (Kinect, Carmine and Xtion) support the same software, so there is no special need for programming or general usage. Can be interface to i.MX processor using USB 2.0 interface and programmed using OPENNI and OPENCV. 2.

1  Introduction   This document explains how to configure a cross compiler running in iMX6Q. The target is the Kinetis L family.  For the iMX6Q, Yocto is used to generate the iMX6Q image. 2 Requirements   Basic knowledge of Yocto and Linux is required. The steps explained were performed for the iMX6Q SABRE-SD and the Freedom KL25.  Installation of Yocto in your host system is needed too. 3 Procedure   The chosen method to configure the cross compiler for the Kinetis L, needs a native compiler that will run in the iMX6Q. Below are the general steps:   Generate native compiler for the iMX6Q and adding the needed packages for the configuration. Get and extract the source packages of the compiler. Configure, build and install the packages Test the generated cross compiler   3.1 Generating packages and native compiler for the iMX6Q   The iMX6Q image needs certain packages in order to configure and generate correctly the cross-compiler. After setting up the environment and chose the MACHINE the below lines added in the local.conf file to install those packages in our rootfs:   IMAGE_INSTALL_append = " gcc g++ binutils libgcc libgcc-dev libstdc++ libstdc++-dev libstdc++-staticdev gawk gzip perl autoconf automake libtool gettext gperf tcl guile gmp mpfr make m4 texinfo flex bison git"   The image to generate is the core-image-minimal:   bitbake core-image-minimal   Once the building is finished, a native compiler for the iMX6 and other packages needed to configure the Kinetis Compiler should be added to the Yocto image. 3.2 Getting and Extracting the Kinetis L compiler   The arm cross compiler version was gotten from CodeSourcery. arm-2011.03-42-arm-none-eabi is used in this document. You can get the source code by:   wget https://sourcery.mentor.com/sgpp/lite/arm/portal/package8736/public/arm-none-eabi/arm-2011.03-42-arm-none-eabi.src.tar.bz2   Once the image was built, boot the imx6 board with this image. Copy the source code (arm-2011.03-42-arm-none-eabi.src.tar.bz) in your target that is running Linux and extract the files.   For example, a new folder was created in /home/root directory:   $ mkdir gcc_test $ cd gcc_test   And extract the files in this folder:   $ tar –jxvf  arm-2011.03-42-arm-none-eabi.src.tar.bz2 $ cd arm-2011.03-42-arm-none-eabi   Create a source and a build folder:   $ mkdir source build   Move all the files to the source folder:   $ mv *.tar.bz2 source/   Create a new folder in /opt where the kinetis cross compiler will be installed   $ cd /opt              $ mkdir arm-none-eabi   3.3 Configure, Build and Install Kinetis Compiler on the iMX6   To configure, build and install the compiler these general steps are followed for certain packages:   Extract the package Configure the package Build and Install the package   Create an environment variable that will specify where the cross compiler will be installed:   $ export INSTALL_PREFIX=/opt/arm-none-eabi   3.3.1 GMP Package   Extract the gmp files: $ cd ~/gcc_test/arm-2011.03-42-arm-none-eabi/source $ tar –jxvf gmp-2011.03-42.tar.bz2   Create a new folder in build directory.

i.MX28 LCD driver 8080 bus interface mechanism please read readme.txt and it will teach you how to use it

         This document will describe how to add open JDK to i.MX yocto BSP. It will take two versions of Linux BSP as an example, one is the lower version of L4.1.15-2.0.0, the other is the latest version of L4.19.35-1.1.0. Adding openjdk-8 to L4.1.15-2.0.0(Ubuntu 16.04 LTS platform) Before adding an open JDK, you must download L4.1.15-2.0.0 BSP according to the i.MX_Yocto_Project_User's_Guide.pdf, and ensure that it can pass the compilation normally, that is to say, there is no error in the compilation. In this example, BSP is compiled using the following command. # DISTRO=fsl-imx-wayland MACHINE=imx6sxsabresd source fsl-setup-release.sh -b build-wayland # bitbake fsl-image-qt5          Then follow the steps below to add openjdk to the yocto layer:   Fetching openjdk-8 from Yocto website # cd ~/imx-release-bsp # cd sources # git clone git://git.yoctoproject.org/meta-java # cd meta-java # git checkout -b krogoth origin/krogoth  [Comment]    Yocto’s version is described in i.MX_Yocto_Project_User's_Guide.pdf 2. Modifying related configurations (1) build-wayland/conf/local.conf Add following lines to the file: # Possible provider: cacao-initial-native and jamvm-initial-native PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native" # Possible provider: cacao-native and jamvm-native PREFERRED_PROVIDER_virtual/java-native = "cacao-native" # Optional since there is only one provider for now PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native" IMAGE_INSTALL_append = " openjdk-8" Save it and exit (2)build-wayland/conf/bblayers.conf Add java layer to the file, like below: BBLAYERS = " \   ${BSPDIR}/sources/poky/meta \   ${BSPDIR}/sources/poky/meta-poky \   \   ${BSPDIR}/sources/meta-openembedded/meta-oe \   ${BSPDIR}/sources/meta-openembedded/meta-multimedia \   \   ${BSPDIR}/sources/meta-fsl-arm \   ${BSPDIR}/sources/meta-fsl-arm-extra \   ${BSPDIR}/sources/meta-fsl-demos \   ${BSPDIR}/sources/meta-java \ "…… Save it and exit. 3. Build openjdk-8 # cd ~/imx-release-bsp # source setup-environment build-wayland #bitbake openjdk-8 -c fetchall          Fetch all packages related to openjdk-8. [error handling]          During downloading packages, you may encounter errors like the following. (1)Fetch fastjar-0.98.tar.gz errors          The error is caused by invalid web address, we can download it from another link, see below: http://savannah.c3sl.ufpr.br/fastjar/fastjar-0.98.tar.gz copy the link to firefox in Ubuntu platform, and it will be downloaded into ~/Downloads # cd ~/imx-release-bsp/downloads # cp ~/Downloads/ fastjar-0.98.tar.gz ./ # touch fastjar-0.98.tar.gz.done   (2)Fetch “classpath-0.93.tar.gz” error          Download it from : http://mirror.nbtelecom.com.br/gnu/classpath/classpath-0.93.tar.gz And copy it to ~/imx-release-bsp/downloads, and create a file named classpath-0.93.tar.gz.done in the directory. # cd ~/imx-release-bsp/downloads # cp ~/Downloads/ classpath-0.93.tar.gz ./ # touch classpath-0.93.tar.gz.done (3) 8 files with tar.bz2 (hotspot-Java jvm)          These similar errors are very likely to be encountered.          These errors are caused by the bad network environment. You can download these packages manually.

Users can also add openjdk-8 before BSP compilation, and then compile it with BSP          According to steps in i.MX_Yocto_Project_User's_Guide.pdf, After running the following two commands, users can modify bblayers.conf and local.conf directly.          For example, steps below have been validated: … … # repo sync # cd ~/fsl-release-bsp # DISTRO=fsl-imx-x11 MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11 # gedit ./conf/bblayers.conf          Add the same contents as above. # gedit ./conf/local.conf          Add the same contents as above. # bitbake fsl-image-gui          During compilation, users may encounter some errors, which can be handled by referring to the methods described above Adding openjdk-8 to L4.19.35-1.1.0(Ubuntu 18.04 LTS Platform) In fact, the steps to add openjdk-8 to l4.19.35 are the same as those described above, and the following steps have been verified. Before adding openjdk-8, i.mx8qxp full image has been compiled with 2 commands below, so we only need to add openjdk-8 here. # DISTRO=fsl-imx-xwayland MACHINE=imx8qxpmek source fsl-setup-release.sh -b build-xwayland # bitbake imx-image-full # cd sources # git clone git://git.yoctoproject.org/meta-java # cd meta-java # git checkout -b warrior origin/warrior          Release L4.19.35_1.1.0 is released for Yocto Project 2.7 (Warrior). # cd ~/imx-release-bsp-l4.19.35 # source setup-environment build-xwayland-imx8qxpmek # gedit ./conf/bblayers.conf          Add meta-java to it.          ……            ${BSPDIR}/sources/meta-java \          ……          Save and exit. # gedit ./conf/local.conf          Add these lines to it.          # Possible provider: cacao-initial-native and jamvm-initial-native PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native" # Possible provider: cacao-native and jamvm-native PREFERRED_PROVIDER_virtual/java-native = "cacao-native" # Optional since there is only one provider for now PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native" IMAGE_INSTALL_append = " openjdk-8" Save and exit.   # cd ~/imx-release-bsp-l4.19.35/build-xwayland-imx8qxpmek # bitbake openjdk-8 -c fetch # bitbake openjdk-8 -c compile [Errors] [Solution] # gedit ./ tmp/work/x86_64-linux/openjdk-8-native/172b11-r0/jdk8u-33d274a7dda0/hotspot/make/linux/Makefile Comment the following lines: ----------------------------------------- check_os_version: #ifeq ($(DISABLE_HOTSPOT_OS_VERSION_CHECK)$(EMPTY_IF_NOT_SUPPORTED),) #       $(QUIETLY) >&2 echo "*** This OS is not supported:" `uname -a`; exit 1; #endif -----------------------------------------          Then continue # cd ~/imx-release-bsp-l4.19.35/build-xwayland-imx8qxpmek # bitbake openjdk-8 -c compile [comment]          Probably similar errors will be encountered during compiling other packages, we can use the same way like above to solve it, see bellow, please!

Some i.MX25 customers reported an issue for the GPT timer, when using 120MHz (240MHz UPLL divided 2) clock source as the GPT per_clk, the timer will not be increased all the time in free-run mode. If using 66.5MHz IPG clock and 133MHz PER clock as the clock source, there are no such issue. There are 4 test cases in the attached test code. Case 0: in CCM_MCR, set bit 5 as 0 for 133MHz HCLK as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b001 ipg_clk (66.5MHz). There is no issue, the GPT counter is fixed at 4 between old_cnt and new_cnt. Case 1: in CCM_MCR, set bit 5 as 0 for 133MHz HCLK as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b010 ipg_clk_highfreq (133MHz). There is no issue, the GPT counter is fixed at 8 between old_cnt and new_cnt. Case 2: in CCM_MCR, set bit 5 as 1 for 240MHz UPLL divided by 2 as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b001 ipg_clk (60MHz). There is no issue, the GPT counter is fixed at 4 between old_cnt and new_cnt. Case 3: in CCM_MCR, set bit 5 as 0 for 240MHz UPLL divided by 2 as the gpt_per_clk source;  in GPT_CR bit[8:6], set 0b010 ipg_clk_highfreq (120MHz). There is issue, the GPT counter is not a fixed value between old_cnt and new_cnt, and sometimes it will be negative. Count 9874: 4 old_cnt: 0x188849dc new_cnt: 0x188849e0 Count 9877: 12 old_cnt: 0x18918400 new_cnt: 0x1891840c Count 9915: 4 old_cnt: 0x189aea90 new_cnt: 0x189aea94 Count 9937: -12 old_cnt: 0x18a42458 new_cnt: 0x18a4244c Count 9967: 4 old_cnt: 0x18adb17c new_cnt: 0x18adb180 In fact, it is not an issue, when using UPLL as the GPT clock source, the maxim frequency should be 60MHz. That's why all other three test case is OK and it only failed on this case.

Some customer need to know how to add support RS485 mode half duplex? Here give some recommends. About i.MX6 UART to RS485 applications 1. Using RS485 mode of UART directly. On hardware, you should use UART_CTS_B to control RX & TX. On software, The link for you reference: Does UART in RS485 mode support only 9 Bit mode for i.MX6 ?  2. Sensing IO direction Automatically via hardware, don't need to tune software. For i.MX8QXP As the linux BSP for i.MX8QXP do not support RS 485 mode, so for the RS 485 using you can use the Sensing IO direction Automatically via hardware, don't need to tune software. As the above i.MX6 design.

Hello all. This document shows how to play the puzzle game “2048” on the RIoTboard running Ubuntu. The RIoTboard is an open source platform featuring the powerful i.MX 6Solo, a multimedia application processor with ARM Cortex-A9 core at 1 GHz.For complete information regarding RIoTboard characteristics and its user manual, you could refer to the following links: RIoTboard wepage: http://riotboard.org/ User Manual: http://www.element14.com/community/servlet/JiveServlet/previewBody/65502-102-2-288206/RIOT_Board_User_Manual_v1.1.pdf Flashing the Ubuntu image to RioTboard. First, we need to get the Ubuntu image and Mfg Tool from the following page: http://www.element14.com/community/docs/DOC-68442/l/riotboard-bsp-images-and-tools-download--android-and-linux Once getting the software, it is required to configure the Boot Configuration Select switches (SW1) for Serial Downloader Mode as shown below: After completing the download of the software, it is requiered to configure the switches for booting from eMMC, as shown below: For additional details regarding Boot modes, you could refer to chapter 4 of the RioTboard User Manual. How to connect EVBUSB2SER to RIoT board for debug terminal. By default, the Debug serial port of the RioTboard is routed to the J18 header (labeled as “Debug”), so, if you have a EVBUSB2SER board, you could use it to access to this serial port by USB. In order to avoid damages between boards, please ensure of the following (on the EVBUSB2SER board): Switch SW1 is in the 3.3V position. Jumper J3 (which enables the level-shifter IC) is removed, as it won’t be requiered. Finally, the connections between EVBUSB2SER and RioTboard should be as follows: Pin Number on EVBUSB2SER header P1 Pin Number on RIoTboard header J18 7 (RXD) <-----> 1 (UART2_TXD) 8 (TXD) <-----> 2 (UART2_RXD) 9 (GND) <-----> 3 (GND) The following image shows both board connected as mentioned: How to change the HDMI display resolution using bootargs. With the serial console connected, you could see the boot log, and stop the boot process for enter to U-Boot for changing the HDMI display resolution (enviroment variable “bootargs”). If you want to know the default vales, you could call the following command:    printenv bootargs So, for changing the resolution to 1920x1080 and then booting, you should do the following: setenv bootargs console=ttymxc1,115200 nosmp video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off saveenv boot Getting the source code of 2048 game and compiling it. On the following webpage you could find the source code of a working 2048 game on a single C file: https://github.com/mevdschee/2048.c On the same page are included the instructions for downloading and compiling it, which are the shown below (using either Serial Debug console or a Terminal window). The Ubuntu image should already include the gcc compiler: wget https://raw.githubusercontent.com/mevdschee/2048.c/master/2048.c gcc -o 2048 2048.c If you want to visualize the source code you could try: cat 2048.c Play! Either using Serial Debug console or a Terminal window (or both) you could now launch the 2048 game my simply launching the compiled executable:    ./2048 Below you can find screen captures of the game running on both scenarios: Hope this will be useful and funny for you. Best regards! /Carlos

After upgrading Ubuntu 11.04 to 11.10, I encountered several building failures such as the following: error:"_FORTIFY_SOURCE" redefined [-Werror] To fix this building issue: 1. Following guides in Initializing a Build Environment | Android Open Source, to get build env ready for Ubuntu 11.10; 2. Edit build/core/combo/HOST_linux-x86.mk and replace:     "HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0"     with     "HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0" Based on further Internet research, I found a Google Groups that summarizes all modifications to fix the building failure encountering in Ubuntu 11.10.
