This document shows the steps for the creation of Archlinux and kernel 4.18.5 on the UDOO board. Required material: UDOO board, Ubuntu 16.04 and SD card. Firts we need u-boot (universal bootloader), for that reason we need update the host. $ sudo apt-get update Then we need the file *.img and SPL for the file system $ wget http://os.archlinuxarm.org/os/imx6/boot/udoo/SPL $ wget http://os.archlinuxarm.org/os/imx6/boot/udoo/u-boot.img Kernel 4.18.5 and file system: $ sudo mkdir archlinux $ wget http://os.archlinuxarm.org/os/ArchLinuxARM-armv7-latest.tar.gz $ sudo tar -xzvf  ArchLinuxARM-armv7-latest.tar.gz $ sudo rm -rf *.tar.gz You must have the following files Now  We are going to burn the memory, we need a 16Gb of space: We need to make sure it is empty Then partitions: $ sudo fdisk /dev/sdc O, P, N, P, 1 space, 8192 default, W At the end the sdc is partition, then create the filesystem partition $ sudo mkfs.ext4 /dev/sdc1 The working directory $ sudo mkdir mnt mount the partition 1 $ sudo mount /devsdc1 mtn/ Now we where the kernel and filesystem are and copy all the file in mnt: $ sudo cp -vr * ~/mnt/ Once it finish we execute $ sync then unmount the partition of sdc1: $ sudo umount mnt/ Now is moment to load the SPL and u-boot: and $ sync we retire the sd and turn on the board. Now you are on ArchLinux. user: alarm                  root: Root Pass: alarm                 pass: root Now the firts thing we must do it is upgrade the keys: $ pacman -key --init $ pacman -key --populate archlinuxarm $ pacman -Syyuu We can add another user: $ useradd - m -g user  -s /bin/bash user_name $ passwd user_name $ paman -S sudo $ visudo Root ALL= (ALL) ALL user_name ALL=(ALL) ALL $ exit For the graphic we are going to install the xorg: $ sudo pacman -S xorg-server $ sudo pacman -S xorg-apps Now we can execute startx and observe the windows of xorg $ startx To have a windows gestor: $ sudo pacman -S sddm $ sudo pacman -S plasma kde-applications $ sudo systemctl enable sddm Reboot and you are ArchLinux graphics windows

meta-avs-demos Yocto layer meta-avs-demos is a Yocto meta layer (complementary to the NXP BSP release for i.MX) published on CodeAurora that includes the additional required packages to support  Amazon's Alexa Voice Services SDK (AVS_SDK) applications. The build procedure is the described on the README.md of the corresponding branch. We have 2 fuctional branches now: imx-alexa-sdk: Support for Morty based i.mx releases imx7d-pico-avs-sdk_4.1.15-1.0.0: legacy support for Jethro releases The master branch is only used to collect manifest files, that used with repo init/sync commands will fetch the whole environment for the 2 special supported boards: i.MX7D Pico Pi and i.MX8M EVK. However the meta-avs-demos can be used with any i.MX board either. Recipes to include Amazon's Alexa Voice Services in your applications. The meta-avs-demos provides the required recipes to build an i.MX image with the support for running Alexa SDK. The imx-alexa-sdk branch is based on Morty and kernel 4.9.X and it supports the next builds: i.MX7D Pico Pi i.MX8M EVK Generic i.MX board For the i.MX7D Pico Pi and i.MX8M EVK there is an extended support for additional (external) Sound Cards like: TechNexion VoiceHat: 2Mic Array board with DSPConcepts SW support Synaptics Card: 2 Mic with Sensory WakeWord support The Generic i.MX is for any other regular i.MX board supported on the official NXP BSP releases. Only the default soundcard (embedded) on the board is supported. Sensory wakeword is currently only enabled for those with ARMV7 architecture. To support any external board like the VoiceHat or Synaptics is up to the user to include the additional patches/changes required. Build Instructions Follow the corresponding README file to follow the steps to build an image with Alexa SDK support README-IMX7D-PICOPI.md README-IMX8M-EVK.md README-IMX-GENERIC.md

NOTE: Always de-power the target board and the aggregator when plugging or unplugging smart sensors from the aggregator. The aggregator portion of the i.MX Power Profiling System sits between the "smart" current sensor boards and the host computer. It provides power and signal connections to each connected sensor board. The communication is done over I2C, where three I2C bus extenders (PCA9518) effectively provide a dedicated bus to each I2C device, to better allow for cabling.  More information will follow... A photo, layout images and schematic attached below.   MBED source for the FRDM-KL25Z is available here: 30848-KL25Z-AGGREGATOR    Smart Sensor Connections At each smart sensor header JP0-JP13, these are the connections provided: 5V: powers the 3.3V regulator on each sensor board 12V: all the gates of all the switching FETs are pulled pulled up to 12V GND: ground connection SCL/TX0: I2C clock line  SDA/RX0: I2C data line  SWD_CLK:  global line for triggering smart sensors to make measurements RESET_B:  global line for resetting all smart sensor boards SWD_IO_n: individual select line for each smart sensor I2C Bus Connection Three I2C bus extenders (PCA9518) provide buffered connections between the FRDM board and all the connected smart sensors. The bus extenders were added to allow for longer cables between the aggregator and the smart sensor boards. Each bus extender has five ports and along with connections that allow extending the bus to more bus extenders. Gate Supply The aggregator contains a boost regulator that boost the 5V input from the FRDM board to 12V. The boosted voltage is fed to each of the smart sensor headers. It's used by the smart sensor board to pull up the gates of the switching FETs above any of the rails under test by at least 4.5V in order to benefit from a lower Rds(on). Caution must be exercised with some older FRDM boards since the 5V from the USB connection passes through diodes with a maximum current of 200mA.  The boost regulator and the load presented by the smart sensor boards may exceed the diode's limit and damage it. (Yes, it's happened... two older FRDM-KL25Z boards were used during development. One of them failed with the diode shorted (~0.05 Ohms), so everything kept working. The other failed with a  short of ~45 Ohms, so it kind of worked but not really...) Application Code for Aggregator  To date, application code has only been developed for the FRDM-KL25Z board. The latest application code resides at: https://os.mbed.com/users/r14793/code/30848-KL25Z-AGGREGATOR/, with the latest binary attached below. SWD Programming of Smart Sensors  Connectors J5 and JP15 are provided as an adapter for programming the smart sensor boards via SWD. JP15 provides power to the smart sensor board, since they have no direct 3.3V input for the KL05Z. An SWD programmer (or suitably modified FRDM-KL05Z board) connects to J5. Both connections use 10-pin 0.05"-spaced ribbon cables. Additionally, when a smart sensor is connected to JP15, J6 provides access to the UART pins of the smart sensor (the I2C pins on the smart sensor also mux out the UART of the KL05Z). No hardware changes are necessary at all; changing the code running on the smart sensor is all that's required. In fact, during the initial prototyping of the smart sensors, the serial UART connection was used instead of I2C. Modify Aggregator To Use SWD Dongle To Program Smart Sensor:  Add a wire as shown on the bottom side of the aggregator board as shown below. This ties 3.3V on the aggregator to the debug header, enabling the voltage level translators on the dongle to communicate with the KL05Z on the smart sensor board.  

NOTE: Always de-power the target board and the aggregator when plugging or unplugging smart sensors from the aggregator. NOTE: See this link to instrument a board with a Smart Sensor. Overview The i.MX Power Profiler system consists of one to fourteen "smart" current sensors, an aggregator shield, and a Kinetis FRDM board (the FRDM-KL25 has been used in prototyping but the FRDM-K64F and FRDM-K66F should also be fully compatible). One of the biggest improvements of this system over its preceeding dual-range measurement system is that the microcontroller on each sensor board allows near-simultaneous measurement of all instrumented rails on a board. The dual range profiler has only a single MCU for all sensors, so only one measurement can be made at a time.  It is intended to be used to instrument one to fourteen rails of a target i.MX appliation board. Ideally, the target board will have been designed with a matching/mating power sense footprint for each rail to be measured.  Each smart sensor can sense current in three ranges with three current sense amplifiers. They are "smart" because each sensor board has a Kinetis KL05Z on it to control the switching FETs and to digitize the analog signals (the sense amplifier outputs and the target's power supply rail voltage). A 1% voltage regulator on each smart sensor provides a good voltage reference right next to the KL05Z to ensure better ADC accuracy. Each smart sensor board communicates via I2C. The aggregator shield has three I2C bus extenders (PCA9518) which essentially provide a dedicated I2C bus for each of the connected smart sensors. The FRDM board's I2C is also connected to one of the bus extenders ports. Individual GPIO lines are routed to each smart sensor's connected along with a ganged reset and trigger line for all of the connected smart sensors. A boost regulator generates almost 12V from the FRDM board's 5V supply, which is used for all the switching FETs on the smart sensor boards. The FRDM board's 5V rail is also routed to each smart sensor, which is regulated down to 3.3V locally on each connected smart sensor. Here is a photo of the very first prototypes after moving to 10-pin 0.05" spaced headers and ribbon cables instead of FFC: The smart sensor is intended to mate with through-hole current sense tap points on the target i.MX application board. Three holes spaced at 0.05" each. When not instrumented with sensor, a short needs to be placed across the outer two pins so that the board will function normally. The through hole connections provide physical protection to the target board, keeping traces from getting ripped off. The ground connection in the center provides a reference for meauring the rail voltage on the target board. A partial layout example of the implementation of the current sense footprint is below, where two 0805 shorting resistors in parallel are placed on each side of the holes. The top trace connects to the regulator output and the bottom to the load, usually an i.MX power supply rail. To include the current sense footprint into a board during the design phase, it should be configured as in the following partial schematic:  Every effort should be made to place the feedback on the i.MX side of the sense points so that the regulator compensates for the additional series resistance of the smart sensor, which effectively eliminates the additional series resistance the smart sensor adds. The Feedback should be before the smart sensor if the switching supply won't tolerate the additional series resistance (i.e., output becomes unstable).

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)  (..)

From iMX 3.1x kernel, all kernel debug messages will be print to debug serial port after UART driver loaded, so if the kernel hang up before tty console driver ready, there will be no kernel boot up messages.   The attached patch can be used to enable the iMX serial debug console in early time, then kernel will not buffer the debug messages.   Note: the default patch is for UART1 (tty0) as the debug port, if you need use other debug port, please modify the code "early_console_setup()" with correct UART port base address.   L3.10.53-Add-early-console-for-debug-message.patch This patch is based on L3.10.53_GA1.1.0 release, it can support iMX6S/DL/D/Q.   L3.14.52-Add-early-console-for-debug-message.patch This patch is based on L3.14.52_GA1.1.0 release, it can support iMX6S/DL/D/Q, iMX6SL, iMX6SX, iMX6UL and iMX7.  

  IMX6 SL boot process is described in Chapter 8 (System Boot) of the Reference Manual. Shortly, the loading boot data from boot SD card is performed in two stages : first read IVT, DCD, then read executable code, using the Boot Data Structure.    At first, boot ROM copies 4K byte (containing IVT and DCD ) from sector 0 of the boot SD card to internal buffer in OCRAM, located in reserved area (0x00900000 - 0x00907000). This area must not be used by user application.   Then, “after checking the Image Vector Table header value (0xD1) from Program Image, the ROM code performs a DCD check. After successful DCD extraction, the ROM code extracts from Boot Data Structure the destination pointer and length of image to be copied to RAM device from where code execution occurs”.   The IVT contains field entry - absolute address of the first instruction to execute from the image.   Note : according to Figure 8-3 (Internal ROM and RAM memory map), only OCRAM Free Area (68KB) from 0x00907000 till 0x00918000 may be used by user’s application.   The attachment contains SD-bootable example.

1. Description     These patches are used to support MPU 8080 LCD on L3.14.52_1.1.0_GA BSP.     They are based on ELCDIF hardware module, iMX6UL and iMX7D is the reference platform.   2. File List -- 0001-Add-ST7789S-MPU-LCD-support-for-iMX6UL-board.patch    Patch to support MPU display for iMX6UL, ST7789S 240*320 panel is the example.   -- 0002-Add-ST7735R-MPU-LCD-support-for-iMX7D-board.patch    Patch to support MPU display for iMX7D, ST7735R 128*128 panel is the example.   -- readme.txt    this file, please refer to it before use the patches   3. Requirement - iMX6UL EVK board or iMX7D SabreSD board. - L3.14.52_1.1.0_GA kernel.   4. How to use -- Copy the patch files to kernel folder.     $ cd ~/L3.14.52_GA1.1.0/build-imx7dsabresd-X11/tmp/work/imx7dsabresd-poky-linux-gnueabi/linux-imx/3.14.52-r0/git     $ git apply ./0001-Add-ST7789S-MPU-LCD-support-for-iMX6UL-board.patch     $ git apply ./0002-Add-ST7735R-MPU-LCD-support-for-iMX7D-board.patch   -- Build the new kernel image:     $ cd ~/L3.14.52_GA1.1.0/build-imx7dsabresd-X11/tmp/work/imx7dsabresd-poky-linux-gnueabi/linux-imx/3.14.52-r0/git     $ export CROSS_COMPILE=~/L3.14.52_GA1.1.0/build-imx7dsabresd-X11/tmp/sysroots/x86_64-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-     $ export ARCH=arm     $ make imx_v7_defconfig     $ make zImage     $ make dtbs   5. How to add a new MPU panel     1) in dts file, such as imx6ul-14x14-evk-i80lcd.dts, update the panel name "lcd_panel",        update the PINs in "pinctrl_lcdif_dat" and "pinctrl_lcdif_ctrl" for the new panel,        the reset and rs PINs can be from GPIO pin, lcd_reset_gpio and lcd_rs_gpio. &lcdif { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_lcdif_dat        &pinctrl_lcdif_ctrl>; display = <&display0>; status = "okay"; display0: display {   mpu-mode;   lcd_reset_gpio = <&gpio3 14 0>;   lcd_panel = "ST7789S-QVGA"; }; };       2) Reference to "mxsfb_st7789s_qvga.c", add a new panel driver code.       3) Add the new panel support in Makefile and Kconfig under "drivers/video/mxc/"       4) Add the new panel support in file "mxsfb.c" and "mxsfb.h"       5) Add the new panel support in default kernel config file "imx_v7_defconfig"   Note: mpu_lcd_fb_test.tar.gz is the test application, for 8080 display, it is not sync display, so software need call ioctl to refresh the LCD.     2016-08-02: Add the uboot reference patch for iMX7D. File: L3.14.52_Uboot_mpu_display.patch  

Some Chinese customers using i.MX series SoC maybe encounter some issues when they download android , u-boot & kernel source code by 'git' command, the following steps will show customer how to get them: 1. Getting repo --No.1 methord # cd ~ # mkdir myandroid # mkdir bin # cd bin # git clone git://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/ <if git failed, use : git clone https://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/> # cd git-repo # cp ./repo ../ --No.2 methord # cd ~ # mkdir bin # curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo # chmod a+x ~/bin/repo [Note]Customers can select one of above to get "repo" 2. Modifying repo File Open ~/bin/repo file with 'gedit' and Change google address From        REPO_URL = 'https://gerrit.googlesource.com/git-repo' To        REPO_URL = 'git://aosp.tuna.tsinghua.edu.cn/android/git-repo'        like following: ## repo default configuration ## REPO_URL = 'git://aosp.tuna.tsinghua.edu.cn/android/git-repo' REPO_REV = 'stable' 3、Setting email address # cd ~/myandroid # git config --global user.email "weidong.sun@nxp.com" # git config --global user.name "weidong.sun" [ Email & Name should be yours] 4、Getting manifest # ~/bin/repo init -u https://aosp.tuna.tsinghua.edu.cn/android/platform/manifest -b android-5.1.1_r1 # cd ~/myandroid/.repo # gedit manifest.xml        Then change the value of fetch to " git://aosp.tuna.tsinghua.edu.cn/android/ ", like following: <manifest>   <remote name="aosp"            fetch="git://aosp.tuna.tsinghua.edu.cn/android/" />   <default revision="refs/tags/android-5.1.1_r1" ...... [Note] android-5.1.1_r1 is version of branch,customer can change it to another. 5、# ~/bin/repo sync          [Note] During runing repo sync, maybe errors will occur like the following: ...... * [new tag]         studio-1.4 -> studio-1.4 error: Exited sync due to fetch errors          Then 'repo sync' exits. But don't worry about it, continue to run the command please ! " ~/bin/repo sync", downloading source code will be continous. 6、Getting Cross Compiler # cd ~/myandroid/prebuilts/gcc/linux-x86/arm # git clone https://aosp.tuna.tsinghua.edu.cn/android/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 # cd arm-eabi-4.6 # git checkout android-4.4.3_r1 7、Getting linux kernel source code        Probably, customer can't normally get linux kernel by using "git clone" command, she can download it directly from the following weblink:        http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/        At first, create a temperary directory, then download kernel into the directory. see following steps: # cd ~ /Downloads # mkdir linux-kernel   Atfer downloading l5.1.1_2.1.0-ga.tar.gz, use 'tar zxvf l5.1.1_2.1.0-ga.tar.gz' command to decompress it.        Then you can find a subdirectory name " l5.1.1_2.1.0-ga" is created, linux source code is in the directory, we should copy all files in the directory to ~/myandroid/kernel_imx/ # cd ~/myandroid # mkdir kernel_imx # cd kernel_imx # cp -a ~ /Downloads/linux-kernel/l5.1.1_2.1.0-ga ./ 8、Getting uboot source code               Probably, customer can't normally get linux kernel by using "git clone" command, she can download it directly from the following weblink:       http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/        We can use similar way to that of linux kernel to get u-boot source code: # cd ~ /Downloads # mkdir u-boot        Download l5.1.1_2.1.0-ga.tar.gz file, and save it in ~ /Downloads/ u-boot, then decompress it, then u-boot source code will be in ~ /Downloads/ u-boot / l5.1.1_2.1.0-ga/, we should copy all file in the path to ~/myandroid/bootable/bootloader/uboot-imx/ # cd ~/myandroid/bootable/bootloader # mkdir uboot-imx # cd uboot-imx # cp -a ~ /Downloads/u-boot/l5.1.1_2.1.0-ga/* ./ 9、Patch android BSP source code        android_L5.1.1_2.1.0_consolidated-ga_core_source.gz is the name of patch. Run following command to patch android. # copy android_L5.1.1_2.1.0_consolidated-ga_core_source.gz /opt/ # tar zxvf android_L5.1.1_2.1.0_consolidated-ga_core_source.gz # cd /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/ # tar zxvf L5.1.1_2.1.0_consolidated-ga.tar.gz # cd ~/myandroid # source /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/ L5.1.1_2.1.0_consolidated-ga/ and_patch.sh # help # c_patch /opt/ android_L5.1.1_2.1.0_consolidated-ga_core_source/code/ L5.1.1_2.1.0_consolidated-ga/ imx_L5.1.1_2.1.0-ga        If everything is OK, the following logs will display on console:               **************************************************************        Success: Now you can build the Android code for FSL i.MX platform               ************************************************************** 10、Patch Freescale extended feathures code        Please refer to chapter 3.3 of Android_User's_Guide.pdf to patch another 2 files:        (1) android_L5.1.1_2.1.0_consolidated-ga_omxplayer_source.gz        (2) android_L5.1.1_2.1.0_consolidated-ga_wfdsink_source.gz [Note]       As for other steps, such as compiling etc, please refer to Android_User's_Guide.pdf that released by NXP. TICS team Weidong Sun 04/01/2016

                                                                                         Watch the Freescale i.MX team boot up Android 5.0 Lollipop in i.mx6 application processors—在线播放—优酷网，视频高清在线观看 The Freescale i.MX Android team has booted up Android 5.0 Lollipop in the SABRE platform for i.mx6 series. Google pushed all of the latest source for its Android release to AOSP on Nov. 5, and the Freescale Android Team started their work. With the previous 6 days to boot Android Lollipop up, the Freescale i.MX Android team enabled the basic features like connectivity, audio/video playback, sensors, inputs and display on day 7! You can see the some changes in the demo video at the beginning of the post. The Freescale i.MX Android team has closely followed almost every version of Android since it is released by AOSP and has good experience on it. Below are some snapshots and pictures for the Android Lollipop.

We have validated Toshiba Smart NAND in our i.MX6SX platform, and boot successfully. The results are as below: 1. chip part number: THGBR2G5D1JTA00,  page_size: 16k+64  pages_per_block: 256 2. test platform: i.MX6SX Some information to take care of: 1. The pin assignment of smart nand is different from common raw nand, that is, Nand pin1 must connect to Vcc, pin2 connects to Vss, pin23 connects to VssQ, pin24 connects to VccQ, pin38 connects to VccQ 2. The ECC layout of FCB page itself must be set according to the i.MX6SX RM, otherwise FCB can't be read correctly. 3. EccBlock0EccType and EccBlockNEccType in FCB must be set as 0, and raw data can be put in DBBT and firmware without any ECC check codes.
