When to improve kernel booting using hibernation [1], I found kernel initialized each component [2] took too much time. One solution is to remove unnecessary module to save time. Another approach is to delay those modules until user space up. Then it won’t lost some features just because hopes to gain benefit on booting speed. This is very useful since hibernation’s trigger point is at the late_initcall [3]. Kernel doesn't need do much module initialize since hibernate will restore those module status later. The detailed implementation is in the attached patch. [1]: hibernation is a technique to store system memory content to storage. Then the device can be shutdown and read the content back after power on. [2]: component means subsystem or driver. [3]: Consult kernel/power/hibernate.c, software_resume

ERR005723           PCIe: PCIe does not support L2 Power Down   Description: When PCIe works as Root Complex, it can exit L2 mode only through reset. Since PCIe doesn't have a dedicated reset control bit, it cannot exit L2 mode.   Projected Impact: PCIe does not support L2 Power Down   Workarounds: The PCIe can be put in PDDQ mode to save on PCIe PHY power and wakeup only by the OOB (Out of Band) wakeup signal (since wakeup by a beacon from link partner is not supported) driven from the link partner (End Point). This signal could be used as a GPIO interrupt to exit this mode. The limitation of this workaround is that the link partner cannot be put into L2.   Proposed Solution:                 No fix scheduled   Linux BSP Status:                 No software workaround available   SW workaround used to fix ERR005723 in Linux BSP Why the original workarounds can’t be implemented in Linux BSP * PCIe controller doesn’t have the reset mechanism that can be used when re-insmod the PCIe driver without power down/up PCIe module. * During the PCie driver rmmod/insmod operations, the PCIe CLKs would be turned off/on. IC can’t guarantee that the PCIe PHY can work well and re-establish the PCIe link properly. One SIMPLE SW workaround for this errata imx: pcie: toggle bit18 of grp1 fix pcie can't exit L2 issue.   Set bit18 of gpr1 before enter into supend, and clean it after resume, can fix the following errata. Errata ERR005723_PCIe PCIe does not support L2 Power Down. About the details, please refer to the attached patch. "0001-imx-pcie-toggle-bit18-of-grp1-fix-pcie-can-t-exit-L2.patch"   The conception of the other SW workaround (System warm-reset) The procedures of the original suspend/resume. Suspend User suspend command echo mem > /sys/power/state All driver call suspend function SRPG,  ARM save all state to memory Enter Stop mode and Power down ARM   Resume:   GPC receive IRQ Wake up system Power on ARM domain. ROM code running Jump to SRPG point Recovery ARM status from memory Call all devices resume function.   Because PCIe only reset by system reset, we need change above follow. Resume:   GPC receive IRQ Wake up system Power on ARM domain. ROM code running Jump to SRPG point Warm Reset system, memory context will be kept. But all peripheral status lost. ROM code running Jump to SRPG point again. Recovery ARM status from memory Call all devices resume function. Resume function call init to initialize it.  And recover to the status saved before.   Impact: Can’t support usb remote wake up, which required 4ms responsive Longer latency, warm reset need some ms.  The recovery of the device status needs some more ms.   Risk:   Current BSP have not tested above follow Device driver have not supported this follow yet. Need additional work to enable \debug\test it.     Modules enabled in this workaround now: * UART * ENET * PCIe   Tests procedure. HW: one i.MX6Q SD boards, and one INTEL pciex1 1000M CT network card.   SW(The images used by me are attached):   * Apply the attached patches(kernel and uboot) to the kernel/uboot source codes, re-build, get the images. Kernel is based on imx_3.0.35_4.0 release, uboot , is based on imx_v2009.08 # build out SD/MMC and USB driver to make DRAM hibernate work     # build pcie in.   *procedure of the suspend/resume tests;     # unload ep's driver --> suspend/resume --> reload ep's driver.   NOTE: Please make sure that the command line contains “no_console_suspend” The command used to enable the console input wake up after login the consol: echo enabled > /sys/devices/platform/imx-uart.0/tty/ttymxc0/power/wakeup   Log when the INTEL CT 1G network card is used: -------------------------------log--------------------------------------------   PM: Syncing filesystems ... done.                                             start suspend Freezing user space processes ...

Development environment: i.MX6Q SabreSD w/ L3.0.35_1.1.0_121218 release. Quoting from Wikipedia about exFAT (exFAT - Wikipedia, the free encyclopedia) as following: exFAT (Extended File Allocation Table) is a Microsoft file system optimized for flash drives. [3] It is proprietary and patent-pending. [1] It is supported in Windows XP and Windows Server 2003 with update KB955704, [2] Windows Embedded CE 6.0, Windows Vista with Service Pack 1, [4] Windows Server 2008, [5] Windows 7, Windows 8, Windows Server 2008 R2 (except Windows Server 2008 Server Core), Mac OS X Snow Leopard starting from 10.6.5, [6] Mac OS X Lion and OS X Mountain Lion. The history of support exFAT in Linux was since from 2.6.x, it involves several parts that will be described followingly. Part 1: Linux Kernel            Enable FUSE (Filesystem in userspace) feature in Kernel Config, then build a new uImage and module if set it to be "M"; Part 2: fuse-2.9.2.tar.gz            Download fuse-2.9.2.tar.gz from http://sourceforge.net/projects/fuse/files/fuse-2.X/, untar it, then build it with following commands: ./configure --prefix=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs/usr --host=`/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-gcc -dumpmachine` --enable-lib --enable-util --enable-example --exec-prefix=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs/usr make sudo make install Part 3: exfat-utils-1.0.1.tar.gz            Download exfat-utils-1.0.1.tar.gz from http://code.google.com/p/exfat/downloads/list, untar it, then build it with following command: sudo scons SYSROOT=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs DESTDIR=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs/sbin CC=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-gcc AR=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-ar RANLIB=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-ranlib STRIP=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-strip install Part 4: fuse-exfat.git git clone git://sources.progress-linux.org/git/releases/baureo-backports/packages/fuse-exfat.git  fuse-exfat.git cd fuse-exfat.git Replace the root SConstruct with the attached one, then execute command: sudo scons SYSROOT=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs DESTDIR=/home/alanz/i.MX6_L3.0.35_121218/ltib/rootfs/sbin CC=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-gcc AR=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-ar RANLIB=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-ranlib STRIP=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-strip install After all above steps done, you can check whether the necessary files under your rootfs like I did as following: http://en.wikipedia.org/wiki/ExFAT#cite_note-uspatent-2alanz@alanz-VirtualBox:~/i.MX6_L3.0.35_121218/ltib$ find ./rootfs/ -name *exfat*./rootfs/sbin/exfatlabel ./rootfs/sbin/mount.exfat ./rootfs/sbin/fsck.exfat ./rootfs/sbin/dumpexfat ./rootfs/sbin/exfatfsck ./rootfs/sbin/mount.exfat-fuse ./rootfs/sbin/mkexfatfs ./rootfs/sbin/mkfs.exfat alanz@alanz-VirtualBox:~/i.MX6_L3.0.35_121218/ltib$ find ./rootfs/ -name *fuse*./rootfs/usr/include/fuse ./rootfs/usr/include/fuse/fuse_common_compat.h ./rootfs/usr/include/fuse/fuse_compat.h ./rootfs/usr/include/fuse/fuse_lowlevel_compat.h ./rootfs/usr/include/fuse/fuse_opt.h ./rootfs/usr/include/fuse/fuse_lowlevel.h ./rootfs/usr/include/fuse/fuse.h ./rootfs/usr/include/fuse/fuse_common.h ./rootfs/usr/include/fuse.h ./rootfs/usr/src/linux/include/linux/fuse.h ./rootfs/usr/lib/libfuse.so ./rootfs/usr/lib/libfuse.a ./rootfs/usr/lib/libfuse.so.2.9.2 ./rootfs/usr/lib/libfuse.la ./rootfs/usr/lib/libfuse.so.2 ./rootfs/sbin/mount.exfat-fuse Check Steps can be referenced by the steps presented on internet.

Based on example code provided in AN4466 I've written a simple memory calibration script for ARM DS-5 that runs same steps and prints out results for DQS, read and write calibration. This script can be run on new boards in order to find optimum calibration settings for the memory controller. Prior to running this script it is necessary to run standard memory initialization script! When bringing up new board: obtain default memory initialization script for memory type you're using (for example from DDR stress tester package) and modify the memory controller settings according to memory device you are going to use. run DDR stress tester with the given configuration on target frequency you're going to use to make memory works with given settings (default values for calibration are  fine in most cases unless there's issues with PCB and/or routing). run memory init script and then the attached script to obtain calibrated values.

The refine to TV mode of R10.3.1 causes dual video function fail. The attached patch recovers dual video function. Attached dual_video.patch only work for RGB output (HDMI support). For legacy TVout (YUV output), the extra patch is necessary, see the attached "legacy_tvout.zip". Refer to Dual video with single UI on i.MX53 SMD with Android R10.4  for setup.

Issue: On i.MX 6Solo designs using LPDD2 memory, the correct settings for two important registries may be confusing to determine. Solution: 1) MMDCx_MDMISC register, LPDDR2_2CH Field: For the i.MX 6Solo processor, this field should always be set to '0'. Reason: Two channel mode is not possible on this processor. Only channel MMDC0 is connected to external pins. 2) IOMUXC_SW_PAD_CTL_PAD_DRAM_RESET register, DDR_SEL Field: For the i.MX 6Solo processor, this field should always be set to "00". Reason: A DRAM Warm Reset requires a response from MMDC1, which is not connected externally on the 6Solo processor, so a Warm Reset never complets. These two issues will be clarified in a subsequent revision of the MCIMX6SDL Reference Manual.

FAE Title Date i.MX Device BSP Description Leo Demo uImage for iMX257 does not support EXT3 filesystem 2/May2013 257 L2.6.31_09.12.00_SDK_images_MX25 For some reason the demo uImage does not support EXT3 filesystems (ext2 is not good for SD cards). kernel has to be recompile with this feature. Xisco start-weston command doesn't work when running from SD card. Only from NFS 3/may/2013 6 RC3.0.35.4.0.0 When compiling rootfs with LTIB, there is a problem that /tmp is tmpfs but keeps the size as 512k, far from common program running requirement, and it's full when system boots up.   When executing start-weston script it needs to write to /tmp and it fails. Only happens with LTIB built BSP.   $ mount -t tmpfs /tmp /tmp        Should be run before executing start-weston Xisco Porting OpenGL ES2 cpp apps for i.MX6 7/may/2013 6 RC3.0.35.4.0.0 When porting OpenGL ES2 cpp apps that were written for i.MX53, you will find an error saying that the function :   fbGetDisplay()   needs more arguments.   All that is needed to fix this error is to change the function to:   fbGetDisplayByIndex(0)   And you will be able to compile your app. Leo Stand-alone MFG and Android MFG are not the same Wed May 15 12:15:17 CDT 2013 6 JB4.2.2_1.1.0 In case you want to flash Android, use the MFG inside the source code tarball and not the stand-alone (the one found directly on the SW & Tools tab). Seems that it takes some time for both to be sync (the same) Leo gst-ffmpeg plugins is broken Thu May 16 13:31:44 CDT 2013 6 RC3.0.35.4.0.0 Attached patch should be applied to gst-ffmpeg code Original Attachment has been moved to: 0001-gstffmpegdemux.c-Remove-deprecated-flow-macros.patch.zip

Notes: First run the playback pipeline then the streaming pipeline. The above example streams H263 video and AMR audio data. Change codec format to your needs. In case where the iMX is the streaming machine, the audio encoder 'amrnbenc' must be installed before.
