This document provides the details for running the Linux Board Support Package (BSP) on the Ubuntu 12.04 64-bit Precise Pangolin Host on an Intel/AMD architecture computer. The 32-bit host is not covered in this document and does have different configuration steps than described here.   An Ubuntu Linux host is used to cross-compile the BSP creating ARM images. The BSP provides a build system named Linux Target Image Builder, (LTIB),  the GNU tool suite for compiling and debugging, U-Boot boot loader, Linux kernel, and a root file system. Resources i.M28EVK- i.MX28 Evaluation Kit Web Page MCIMX28EVKJ Product Summary Page- i.MX28 Download Collateral L2.6.36_MX28_SDK_10.12_Source- BSP Source Download Linux documentation - i.MX28EVK Documentation Ubuntu 12.04.1 LTS (Precise Pangolin)- Ubuntu 12.04 Release Download Ubuntu 12.04.01 A dedicated computer running Ubuntu or a Virtual Machine, (VMware or VirtualBox), can be used for running the Host Ubuntu software. The Ubuntu image is available for downloaded from the Ubuntu site: Ubuntu 12.04.1 LTS (Precise Pangolin).   This Ubuntu host ISO was used with the md5 checksum: ubuntu-12.04.1-desktop-amd64.iso  06472ddf11382c8da1f32e9487435c3d   One way to acquire the ISO is to use zsync to download: zsync http://releases.ubuntu.com/12.04/ubuntu-12.04.1-desktop-amd64.iso.zsync  Once downloaded, installing the ISO is user preference - either a dedicated Linux PC or in a Virtual Machine.   Download i.MX28EVK BSP and Documents The BSP download is from this site L2.6.36_MX28_SDK_10.12_Source and the documents from Linux documentation that requires a free registration to specify login credentials,   436e0b8e1c7976c657d530a45f9dbd0c L2.6.35_10.12.01_SDK_source_bundle.tar.gz de0274320a17c1e989d1ef5c088973e2 L2.6.35_10.12.01_SDK_docs.tar.gz   Ubuntu Host Setup Ubuntu login credentials of User: user Password: user are used for this documents. Host Package Update Once logged in to the Ubuntu host, the existing packages are brought up to date to the latest version before installing the BSP. The Ubuntu package manager used is apt-get. $ sudo apt-get update $ sudo apt-get upgrade  01. Check all installed packages for new revisions 02. all newer packages found are installed.   Addtional packages are required for the ltib build system. Ubuntu Configuration PDF evince is the default pdf reader, another option is zathura. $ sudo apt-get install zathura Sudo Priviledges LTIB requires super user priviledges for some operations. To enable a visudo entry is added to the sudo'ers file. For more information run 'man visudo'.   $ sudo visudo  The first word, user, is the login account 'user' This can be changed to whatever login you used, or if you have groups configured you can provide a group that developers are in - refer to the man page for sudo for details. Add this line:   user ALL =NOPASSWD: /usr/bin/rpm/ /opt/freescale/ltib/usr/bin/rpm   Default Shell Ubuntu uses the default shell 'dash'. This however causes failures on bash scripting which is part of the ltib system. Change the default shell from 'dash' to 'bash'   $ sudo update-alternatives --install /bin/sh sh /bin/bash 1  CCACHE ccache provides a fast C/C++ compiler cache which is supported in the ltib system. To configure once the ccache package has been installed: $ sudo apt-get install ccache $ ccache -M 50M $ ccache -c  02. Set the cache limit to 50 Meg 03. Clear the cache folder   Directory Layout The following directory structure is used: /home/user/freescale/imx28/ |-- archive |-- L2.6.35_10.12.01_ER_source |-- L2.6.35_10.12.01_SDK_docs |-- L2.6.35_10.12.01_SDK_scripts |-- ltib |-- ubuntu-imx28-ltib-patch   The archive directory is where the BSP and documents are stored; command to create the directory: $ mkdir -p ~/freescale/imx28/archive   Extract SDK and Documents The following instructions were used to extract the contents of the Software Development Kit:   $ cd ~/freescale/imx28/archive $ tar -zxf L2.6.35_10.12.01_SDK_source_bundle.tar.gz -C ..    01. Change into the directory containing the tar ball that is compressed. 02. Extract the contents into the directory above (-C ..) the current directory -z unzip -x extract -f L2.6.35_10.12.01_SDK_source_bundle.tar.gz   $ tar -zxf L2.6.35_10.12.01_SDK_docs.tar.gz  01. Extract the contents into the directory above (-C ..) the current directory     -z unzip     -x extract     -f L2.6.35_10.12.01_SDK_docs.tar.gz this file The contents of both tar files are now in the directory /home/user/freescale/imx28. Install BSP Sources After extracting the content from the L2.6.35_10.12.01_SDK_source_bundle.tar.gz the file L2.6.35_10.12.01_SDK.source.tar.gz contains all the sources and the build system. Extract the contents and install. This will create the ltib directory which is the build system. $ tar -zxf L2.6.35_10.12.01_SDK_source.tar.gz $ cd L2.6.35_10.12.01_ER_source $ ./install  Read the license information and accept by entering YES. An installation directory is then asked for, providing:  .. which is the parent directory. The installation script copies the packages and will inform you that 'Installation complete, your ltib installation has been placed in ../ltib, to complete the installation: cd .../ltib ./ltib  HOWEVER before doing this, there are packages and patches that need to be applied to run ltib on Ubuntu 12.04.01. Ubuntu Software Packages for LTIB The following packages are required. The script pkg-setup.sh attached below has these packages which can be downloaded and executed to install. $ sh pkg-setup.sh  sudo apt-get -y install gettext libgtk2.0-dev rpm bison m4 libfreetype6-dev sudo apt-get -y install libdbus-glib-1-dev liborbit2-dev intltool sudo apt-get -y install ccache zlib1g zlib1g-dev gcc g++ libtool sudo apt-get -y install uuid-dev liblzo2-dev tcl wget libncurses5-dev sudo apt-get -y install libncursesw5-dev lib32z1 libglib2.0-dev xsltproc sudo apt-get -y install ia32-libs libc6-dev-i386 The file pkg2-setup.sh contains optional packages for development. To install, download and execute: $ sh pkg2-setup.sh Please refer to the document ltib_build_host_setup.pdf for more information on host setup. Patching LTIB The location of files from the glibc-devel and zlib Ubuntu 12.04 packages has changed from 9.0.4 Ubuntu which the original ltib was released against. To update ltib operation the following patches are implemented from the directory ~/freescale/imx28/ltib 1. The file ltib is changed at line 2387 adding the '-v' option to the rpm call OLD:     system('rpm --force-debian 2>/dev/null') == 0? NEW:     system('rpm -v --force-debian 2>/dev/null') == 0? 2. The file bin/Ltibutils.pm is updated to support glibc-devel and zlib.   glibc-devel update: Line 563 add check for /usr/lib32/libm.so 'glibc-devel' => sub {-f 'usr/lib/libm.so' || -f '/usr/lib64/libz.so' || -f '/usr/lib32/libm.so'},   zlibc update: Line 584 add /lib/x86_64-linux-gnu/libz.so* zlib => sub{my @f = (glob('/usr/lib/libz.so*'),               glob('/lib/x86_64-linux-gnu/libz.so*'),               glob('/lib/libz.so*'),   The above patches are also in the attachment 0001-patches-for-12.04-ubuntu.patch.   LTIB packages also need adjustments to correctly build on Ubuntu. The tar file below, ubuntu-imx28-ltib-patch.tgz contains all the updates. Download and extract the contents at the same directory level as your ltib source directory. $ tar -zxf ubuntu-imx28-ltib-patch.tgz ├── ltib ├── ubuntu-imx28-ltib-patch └── ubuntu-imx28-ltib-patch.tgz Change directories to ubuntu-imx28-ltib-patch and then run the install-patches.sh script. $ cd ubuntu-imx28-ltib-patch $ ./install-patches.sh   The following packages are updated: lkc mtd-utils mux_server sparse Create SD Card Using Ubuntu Host The tar file L2.6.35_10.12.01_SDK_scripts.tar.gz contains scripts for writing the images from the ltib build to a SD card. Extract the content, copy the scripts to the ltib directory, and update the mk_mx28_sd script to work with the updated fdisk command.   $ tar -zxf L2.6.35_10.12.01_SDK_scripts.tar.gz $ cd L2.6.35_10.12.01_SDK_scripts $ cp mk_hdr.sh ~/freescale/imx28/ltib $ cp mk_mx28_sd ~/freescale/imx28/ltib $ cd ~/freescale/imx28/ltib  Edit mk_mx28_sd script and add the 'u' at line 177 then the o command after. This changes cylinders to sectors.   OLD: echo "o n   NEW: echo "u o n   Once updated to create the SD card which is at /dev/sdb: $ ./mk_mx28_sd /dev/sdb  NOTE: if mounted automatically, you need to unmount for the script to work $ sudo umount /dev/sdb*      Media Booting Selection The i.MX28EVK has a boot option to execute from the SD Card in Slot 0 which is located on the bottom of the EVK. On the top of the EVK there are switches that are read during the start up process to determine what boot media to use. The SD Card in slot 0 is used for this example which requires the settings: B3/DIP1 B2/DIP2 B1/DIP3 B0/DIP4 1 0 0 1 Refer to the user guide, i.MX28_Linux_BSP_UG.pdf section 3.2.1. Boot Modes for all options. The user guide is found in the Linux documentation bundle documentation.  Refer to the next section for a picture showing the boot switch location and the SD Card Slot 0 location. Cable Connections A computer serial port is connected to the i.MX28EVK serial port. The communication setting is 115200 baud, 8 data bits, No parity, and 1 stop bit. There is NO flow control set for this port. This is typically shown as 115200, 8N1. The power supply is connected  

Issue: During DDR3 Burst Write, the DQS strobe signal must be driven low for a minimum of 0.3 x cycle period on the last data clock cycle before it is released. This ensures sufficient time for the write to be strobed correctly. When measuring this timing parameter, it has often been found to be too short. This may be contributing to write errors on customer boards, depending on the signal layout used by the board. Root Cause: The internal DQS strobe enable signal is controlled by the MMDC, which is tied to the SDCLK clock signal. But the DQS strobe signal can be delayed in the MMDC to match different SDCLK trace lengths by using Write Leveling parameters to ensure the the DQS strobe edge reaches the DDR3 device at the same time the SDCLK edges reaches the device. If the write level delay is too long, the MMDC can crop the end of the DQS strobe signal too short, causing a violation of the Write Post Amble Delay timing specification and potentially leading to  write errors. How much delay in the Write Leveling parameter would cause this problem? The Reference Manual states that a delay around half a cycle may cause problems, but testing on some boards indicates that delays even as short as 1/4 a cycle could cause violations of the Write Post Amble Delay. Solution: The MMDC was designed with the ability to add extra time to the strobe enable period during write procedures. This parameter is referred to as Write Additional Latency. It is found in the MMDCx_MDMISC register and the field is labeled as WALAT. Incrementing the value of this register field by one adds a full clock cycle delay to the Write Post Amble period, and ensures enough time at the end of a burst write to guarantee a correct write. There is no maximum value to Write Post Amble Delay. Setting WALAT = 1 (or larger if WL parameters are larger) will cause a small hit in overall performance, but will add to the reliability of write operations, particularly on boards that require larger WL parameter settings.

Structures to be modified The main table that needs to be modified is in C:\WINCE600\PLATFORM\COMMON\SRC\SOC\COMMON_FSL_V2_PDK1_9\NAND\INC\NANDTYPES.h. Add the Nand specific information to the following structure. typedef struct _NandChipInfo { FlashInfo fi; //@<<info> FlashInfo structure BYTE NANDCode[NANDID_LENGTH];//@<<info> NAND full ID BYTE NumBlockCycles; //@<<info> flash erase address cycle BYTE ChipAddrCycleNum; //@<<info> flash access address cycle BYTE DataWidth; //@<<info> 8/16 bits data width BYTE BBMarkNum; //@<<info> MAX_MARK_NUM = 4 BYTE BBMarkPage[MAX_MARK_NUM];//@<<info> MAX_MARK_NUM = 4 BYTE StatusBusyBit; //@<<info> interleave mode support BYTE StatusErrorBit; //@<<info> interleave mode support WORD SpareDataLength; //@<<info> spare area size BYTE CmdReadStatus; //@<<command> read status BYTE CmdRead1; //@<<command> read first 256 bytes data BYTE CmdRead2; //@<<command> read last 256 bytes data BYTE CmdReadId; //@<<command> read device ID BYTE CmdReset; //@<<command> reset nand flash BYTE CmdWrite1; //@<<command> sequence data input BYTE CmdWrite2; //@<<command> page program BYTE CmdErase1; //@<<command> block erase BYTE CmdErase2; //@<<command> block erase NANDTiming timings; //@<<info> NAND timing parameters }NandChipInfo, *pNandChipInfo; All information from NANDCode to CmdErase2, can be obtained from the Nand Datasheet. The structure FlashInfo, is filled in with data obtained from the Nand Analysis sheet. Please check this link to see how to create this spreadsheet from Nand Datasheets. typedef struct _FlashInfo { FLASH_TYPE flashType; DWORD dwNumBlocks; DWORD dwBytesPerBlock; WORD wSectorsPerBlock; WORD wDataBytesPerSector; }FlashInfo, *PFlashInfo; In the similar way the Nand timings calculated from the spreadsheet are add into this structure. typedef struct _NANDTiming { BYTE DataSetup; BYTE DataHold; BYTE AddressSetup; BYTE DataSample; }NANDTiming, *PNANDTiming; Remember to do a clean sysgen and build.

On L4.1.15 BSP, PWM output clock may be not stable, for example, it may switch between 200KHz and 50KHz. PWM clock source is perclk, in running mode, perclk is 24MHz, while in low power idle mode, perclk is reduced to 6MHz, so PWM output clock is reduced to 1/4. To keep PWM output stable clock, we should let perclk stay in 24MHz in low power idle mode. Attached is the patch for 6UL and 6ULL.

Setting up the clocks for PCIe is a bit tricky, especially for bare-metal or if not using the Linux BSP. The ENET PLL (PLL6) 100 MHz (SATA) PFD output MUST be enabled in order to access the registers in the PCIe IP block. (To enable this clock, set CCM_ANALOG_PLL_ENET[ENABLE_100M (bit 20)].) This is not well documented in the RM, but follow these steps to insure reliable performance.

Descriptions on the issue: running “uuu uuu-android-mx8mq-evk-emmc.lst” No any problem, downloading images is OK. running “uuu_imx_android_flash.bat -f imx8mq -a -e” Below lines will be showed on windows console: flash the file of u-boot-imx8mq.imx to the partition of bootloader0 <waiting for any devices>             Then downloading operation stopped. ------------------------------------------------------------------------                 In order to help uses save development time, I tested above 2 commands for downloading images on windows 7 64bit and windows 10 64bit respectively.                 Below is detailed steps for the operation: Hardware Preparations (1) Switch SW802 on i.MX8MQ EMEK, set 1-4 off, 2-3 on i.MX8MQ is at usb serial download mode. (2) Connecting J1701 to PC USB by a USB OTG cable. (3) Connecting J901(usb type c) to PC USB by a USB 3.0 cable. (4) Plugging [email protected] adapter into Power Jack (J902) (5) Power on I.MX8MQ board via SW701 Switch Software Preparations (1) Related windows drivers for i.MX8MQ MEK                 Windows 7 64bit or windows 10 64bit will find new devices and begin to search and install corresponding drivers, like below:                 Probably windows 10 64bit can’t automatically install CP2105 driver from official website of manufacture: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers                 Then installed it manually. (2) Power off i.MX8MQ MEK (3) Installing winusb driver by zadig                 According to method described in uuu.pdf, download zadig tool from https://zadig.akeo.ie/, and install it to windows 7 64bit . [Note] windows 10 64bit doesn’t need to install winusb driver. Press “Install WCID Driver” Button (4) Downloading Android SDK Manager Download SDK Manager from : http://visualgdb.com/android/install_redir?item=SDK After downloading it, decompress it, and run SDK Manager application: Press OK. Then press “Close” Close SDK Manager Installation Guide . Find the directory of SDK Manager installation, and enter into “platform-tools”, like below: D:\i.MX8-Projects\IMX8MQ-MEK-windows-drivers\android-sdk_r24.4.1-windows\android-sdk-windows\platform-tools Copy items in blue rectangle to C:\windows\system Copy items in red rectangle to C:\windows\system32     Beginning to download android images to I.MX8MQ MEK via UUU Tool (1) Downloading android DEMO images for i.MX8MQ MEK https://www.nxp.com/support/developer-resources/software-development-tools/i.mx-developer-resources/evaluation-kit-for-the-i.mx-8m-applications-processor:MCIMX8M-EVK?tab=Design_Tools_Tab After downloading it, decompress it to a directory.  Like below: (2) Downloading UUU Tool https://github.com/NXPmicro/mfgtools/releases After downloading uuu.exe,  copy it to the directory of android 9.0 demo image , see above. (3) Run command “uuu_imx_android_flash.bat -f imx8mq -a -e” ----Power on i.MX8MQ MEK. ----open a command line window ---open Hyper terminal ( set it 115200 bps) ---run “uuu_imx_android_flash.bat -f imx8mq -a -e”           For windows 10 64bit, downloading images will be done without any errors.    But for windows 7 64bit, downloading images will stop at “ waiting for any devices”.    It means Android ADB driver will be needed. Follow the steps below to solve the problem. Right button, click “update driver” Close it.           Then downloading operations will be automatically continued. OK， done.
