NFS After LTIB installation, follow the instructions below to configure and build Linux Image and Root File System. TIP: Type: $./ltib --help to get more information on ltib In the folder where LTIB were installed, execute the file: $./ltib It should take some minutes to complete the installation. Configure the ltib to select the options and packages to be defined and installed in Linux Image and Root File System. $./ltib -c     or     $./ltib -m config The menu configuration should appear: To configure for use the system with NFS, go to: Target Image Generation -> Target Image -> NFS Only For basic compilation, exit LTIB. It will compile and add some pre-built packages to make the target file system.

    Attached is the SDHC DMA read supported patch, it is based on WCE600_MX51_ER_1104, it was verified on iMX51 EVK board. The SDHC DMA read can reduce the NK copy time, in this way it can speed up the WinCE boot.

Video Unit Test The BSP provides a package that allows testing of several i.MX 31 peripherals on the PDK. The name of this package is 'imx-test'.   The name of the package may vary according to SDK release, at the time of the writing SDK 1.4 was used, on SDK 1.2 the name of a similar package was 'mxc-misc'   For more information on the imx-test package refer to the SDK 1.4 manual, imx31_Linux_RM.pdf, chapter 49 - Unit Tests. This file is available on BSP tarball Testing To test the image sensor and the display on the PDK follow the steps below: Enable imx-test and util-linux packages: $ ./ltib -c Once "ltib" finishes boot the system.

One of the important features that differentiates Xenomai from other real-time Linux extensions is its ability to offer hard real-time support to user-space applications. Ease of use of the user-space programming model should outweigh any gain one could expect from running the application directly from kernel space. User-space applications are memory protected from other processes, thus cannot crash the kernel should something goes wrong. Xenomai also provides generic building blocks for building different RTOS interfaces called skins, These skins imitates the different RTOS APIs thus allowing easy porting of existing applications to Xenomai. Required software 1. The current BSP version for iMX6 from Freescale is 3.0.35 does not fully work with the latest version Xenomai because the accompanying I-pipe patch does not support SMP. To use the latest I-pipe patch, a newer Linux kernel is need. Grab the latest stable kernel:   $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git   $ cd ~/linux-stable   $ git branch -a   $ git checkout remotes/origin/linux-3.8.y -b linux-3.8.y   $ git checkout v3.8.1 -v v3.8.1 2. Configure the kernel. Make sure the kernel is built without any errors before patching it with Xenomai.   $ export ARCH=arm   $ export CROSS-COMPILE=arm-fsl-linux-gnueabi- $ make imx_v6_v7_defconfig $ make -j16 uImage 3. Note that this is a device-tree enabled kernel. You'll also need to generate the flattened device tree that U-Boot will pass to the kernel.   $ make imx6q-sabrelite.dtb 4. This step is not needed if your U-Boot supports device-tree kernel. Grab the latest U-Boot: $ git clone git://git.denx.de/u-boot.git $ cd u-boot/ $ make mx6qsabrelite_config $ make -j16 5. The boot script will need to updated to load the device-tree into memory and pass it to the bootm command.   U-Boot > setenv bootcmd 'fatload mmc 1 0x22000000 uImage; fatload mmc   1 0x11000000       imx6q-sabrelite.dtb; bo otm 0x22000000 – 0x11000000' 6. Grab the latest I-pipe patch from Adeos    $ wget http://download.gna.org/adeos/patches/v3.x/arm/ipipe-core-3.8-   arm-1.patch 7. Grab the latest Xenomai    $ wget http://www.xenomai.org/index.php/Xenomai:News#2013-10-           05_Xenomai_2.6.3   $ tar -xvjf xenomai-2.6.3.tar.bz2 Patching the kernel 1. Prepare the target kernel. This is to assume that the Linux kernel and I-pipe patch are located relatively to Xenomai.   $ cd xenomai-2.6.3   $ ./scripts/prepare-kernel.sh --linux=../linux-stable/ --adeos=../linux-stable/ipipe-core-3.8-arm-1.patch –arch=ARM   $ ./configure CFLAGS="-march=armv7-a -mfpu=vfp3" LDFLAGS="-march=armv7-a -mfpu=vfp3" --host=arm-fsl-linux-gnueabi 2. Build and installation   $ make -j8   $ sudo root   $ export PATH=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/:$PATH   $ make DESTDIR=~/BSP/ltib/rootfs install    Testing the installation 1. Verifying the kernel. If everything works, the kernel boot logs should messages like:    I-pipe: head domain Xenomai registered.   Xenomai: hal/arm started.   Xenomai: scheduling class idle registered.   Xenomai: scheduling class rt registered.   Xenomai: real-time nucleus v2.6.2.1 (Day At The Beach) loaded.   Xenomai: debug mode enabled.   Xenomai: starting native API services.   Xenomai: starting POSIX services.   Xenomai: starting RTDM services. 2. Comparison of Xenomai and unpatched Linux kernel real-time performance. We ran a couple benchmarks on a Freescale I.MX6q Sabrelite board to do the comparison. The tests used default configurations and fully stressed the system in order to measure scheduling jitter.                               Linux   Kernel     Zero load     100% loaded     Average latency   (us)     Worst-case   latency (us)     Average latency   (us)     Worst-case   latency (us)     Standard     4.625       41.311     5.120     1849.91   Patched with   Xenomai     4.825       15.568     6.654     16.655 The tests measure the jitter relative to expected time on a periodic task running every 1 millisecond. Data show the Xenomai implementations stand out for having by far the smallest difference between light and full load in the worst case. Stock Linux fare much worse as the timers miss a lot wake ups.

This is the procedure and patch to set up Ubuntu 13.10 64bit Linux Host PC and building i.MX6x L3.0.35_4.1.0.

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.
