It is often not easy to use company network to flash application, due to network security (proxy, etc...). We will see in this tutorial, how to flash a Linux application in a SD card with ONLY a SD card reader and simple standard Linux commands. SD card Memory Map A Linux application is divided in 3 parts: the bootloader the Linux Kernel the Linux Rootfs We will flash sequentially these 3 parts Flashing U-boot With the SD card Reader, we will flash the yellow part. In the [...]/ltib/rootfs/boot/ folder $ sudo dd if=u-boot.bin of=/dev/sdb bs=512 skip=2 seek=2 && sudo sync Flashing Linux Kernel With the SD card reader, we will flash the green part. Keep in mind that 1MB=1048576B -> Kernel Offset. $ sudo dd if=uImage of=/dev/sdb bs=1048576 seek=1 && sudo sync Configure U-boot variables To launch the Kernel, you need to configure U-boot. Plug the serial cable on the EVK: 115kbps, 8 bits, 1 stop and no parity EVK switches must be configured as below: DS1 DS2 DS3 DS4 DS5 DS5 DS7 DS8 DS9 DS10 Boot from SD/MMC Card 0 0 0 0 0 0 1 1 0 0 Put the SD card in the EVK (bottom slot) and launch the app. In the hyperterminal type:   BBG U-Boot > printenv To print environnement variables Modify the bootcmd: BBG U-Boot > setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc read 0 ${loadaddr} 0x800 0x1800;bootm' "0x1800" is the size of the kernel. Must be bigger than uImage Kernel file (0x1800x512Byte=3MB) If you want to use the WVGA as display screen (kernel need to be configured with CLAA support), for LTIB1007 and after (before it was 'wvga' option): Script for LTIB1007's u-boot on i.MX51 EVK (copy/paste in the hyperterminal): setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc read 0 ${loadaddr} 800 1800 ; bootm' setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw  init=/init' setenv bootargs_base' setenv bootargs console=ttymxc0,115200 di1_primary console=tty1' setenv bootcmd 'run bootcmd_mmc' saveenv Script for LTIB1007's u-boot on i.MX53 EVK (copy/paste in the hyperterminal): setenv bootcmd_mmc 'run bootargs_base bootargs_mmc; mmc read 0 ${loadaddr} 800 1800 ; bootm' setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw  init=/init' setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 di0_primary console=tty1' setenv bootcmd 'run bootcmd_mmc' saveenv You must have the following printenv: BBG U-Boot > printenv bootdelay=3 baudrate=115200 loadaddr=0x90800000 netdev=eth0 ethprime=FEC0 uboot_addr=0xa0000000 uboot=u-boot.bin kernel=uImage bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serveri p}:${nfsroot},v3,tcp bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; boot m load_uboot=tftpboot ${loadaddr} ${uboot} ethact=FEC0 bootargs=console=ttymxc0,115200 di1_primary root=/dev/mmcblk0p1 rootwait rw init =/init bootcmd_mmc=run bootargs_base bootargs_mmc; mmc read 0 ${loadaddr} 800 1800 ; bo otm bootargs_mmc=setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait rw init=/i nit bootargs_base=setenv bootargs console=ttymxc0,115200 di1_primary bootcmd=run bootcmd_mmc stdin=serial stdout=serial stderr=serial</br> Environment size: 748/131068 bytes BBG U-Boot > Create ext3 partition With the SD card reader, create an ext3 partition. You can use gparted, a graphical partition manager tool. Launch gparted: $ sudo gparted Create a new ext3 partition, with 20MB of offset: Copying Linux To copy rootfs folder generated by LTIB, type in the shell: $ sudo cp -r /[…]/ltib/rootfs/* /media/FreescaleSD/ && sudo sync Test application Put the SD in the slot slot and launch the application. Password is root.

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

Q: Q&A: Where to find IBIS Models on the web? A: In the first figure (FSL driving 100 ohm), the processor is DC coupled to a transmission line and terminated at the far end with a 100-ohm resistor. The results look pretty normal for this. In the other figure, the processor is dc coupled to a transmission line, then ac coupled to another transmission line segment (0.1u) with 50-ohm resistors to ground, and then drives the inputs of an HCSL clock buffer. The results are pretty un remarkable. The top red signal in the trace is one of the IMX6 clock outputs, the first green signal is the other clock output, and the last green signal (from top to bottom that is) is the differential signal seen by the clock buffer. The customer is concerned about the asymmetrical drive of the processor. It looks like LVDS clock outputs do not like to be AC coupled. This simulation resembles the way the clock is handled in the Smart Device schematics where the clock is AC coupled to the reference clock inputs on the PCIE connector. The ibis files were downloaded from the web (21x21_imx6q, consumer variant). So a few updates: I had the customer download the latest duallite IBIS models. Previously they were apparently using the quad/dual models. They are going to update HyperLynx and are going to run a simulation and let me know if they still see the same issue. He said he's using "linesim". Meanwhile he noticed a different problem with the duallite/solo IBIS models. Although the datasheet says LVDDR3 (1.35V) is supported, there is no model for DDR3_L either as input or output. The same model existed in the quad/dual models. Do you know why this option is not in the duallite IBIS models? Thanks! A ctm of mine would like to get the IBIS model with LVDDR3 support on the i.MX6 DL. For mx6-duallite IBIS models for DDR3L memory (1.35V). It'd be great if the models matched the quad version. Please find the new updated IBIS file in website. http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6DL&nodeId=018rH3ZrDRB24A&fpsp=1&tab=Design_Tools_Tab

Description by Google:      Wi-Fi scan-only mode is a new platform optimization that lets users keep Wi-Fi scan on without connecting to a Wi-Fi network, to improve location accuracy while conserving battery. Apps that depend on Wi-Fi for location services can now ask users to enable scan-only mode from Wi-Fi advanced settings. Wi-Fi scan-only mode is not dependent on device hardware and is available as part of the Android 4.3 platform. Comments by Freescale:      In order to enable wifi scan mode, we should make sure wifi driver shouldn't be removed while switching off wifi from Setting. Additionally, android4.3 has introduced one CTS test to force us to change all loadable modules into kernel built in. The reason is loadable modules are often used by rootkits and other exploits. so there will be big risk in security. OK, now let's try to keep up with the pace of AOSP.      For AR6003, we are using compat-wireless driver which accommodates all linux kernel since 2.6.We are now using olca-3.4 wifi driver but our kernel version is 3.0.35.  It is not a simple change to be directly compiled into kernel since it is lack of the basic file structure for ath6kl driver. This has been double confirmed by support guy from Atheros. More terribly, Atheros has no plan to publish new version for AR6003 but just maintain it. Yeah, my pitiful baby. Say goodbye to scan mode.      This is why this document come into being. AR6003 is our default wifi module bounded to our imx6 serial board. So formal release will lose this important feature for this limitation. Here I will give out patches to enable this feature using another wifi module-----Realtek 8723as. Ok, now let's welcome this new star. Patches description:          Patch for kernel--------Change loadable driver modules to compiled into kernel, this will let wlan0 and p2p0 interfaces still can be operated although you have switched off wifi in Setting UI.      Patch for device/fsl--------Firstly, I delete one rfkill operation in init.rc which is obsolete for BT setting. If still keep it here, it will soft block wifi interface through mac80211 rfkill. Then I clean up some setting for wifi driver module.      Patch for hardware/libhardware_legacy-------Since wifi driver is already directly built in kernel, HAL will have no need to load driver now. Refactor it and optimize it. Test it manually:          If you have one sdio rtl8723as wifi module in hand, you can test it like the following to see wifi scan mode works: Firstly, disable wifi in Setting UI. then you can check netcfg result, you will see wlan0 and p2p0 are still there, only down state: Go "advanced" menu in wifi setting,Turning on the checkbox of "Scanning always available". Check netcfg result again, Oh Oh, wlan0 and p2p0 are up: Manually "scan" through "wpa_cli" tool, you will see it works:

Here is an example for i.MX28 EVK board to support SPI NOR boot in uboot, kernel and MFGTool.   Attached files are the patches to support SPI NOR flash on i.MX28 EVK bord based on L2.6.35 ER11.09.01 BSP. It was verified on Spansion s25fl256s SPI NOR. "ER11.09.01_uboot_imx28_spi_nor.patch" is the Uboot patch. "ER11.09.01_kernel_imx28_spi_nor.patch" is the kernel patch. "ucl.xml" is the updated MFGTool config file, please update it to "Mfgtools-Rel\Profiles\MX28 Linux Update\OS Firmware\ucl.xml".   The uboot boot paramters for SPI: setenv bootargs_base 'setenv bootargs console=ttyAM0,115200' setenv loadaddr 0x42000000 setenv bootargs_spi 'setenv bootargs ${bootargs} root=/dev/mtdblock2 rootfstype=jffs2 rootwait rw ip=none' setenv bootcmd_spi 'run bootargs_base bootargs_spi;sf probe 2:0; sf read ${loadaddr} 0x100000 0x300000;bootm' setenv bootcmd 'run bootcmd_spi' saveenv   To boot the board from SPI NOR s25fl256s, the 4KB page region of the NOR should be put to top, the last 128KB of the NOR address space. The uboot.sb is about 220KB, it can't be put to 4KB and 64KB combined region. The IMX28 boot ROM can only handle simple page size for boot. All 4KB page region or all 64KB page region are both OK for boot, but combined region can't boot.   For default, the s25fl256s NOR's 128KB 4KB page size region is at the bottom of the NOR, we should update the OTP to set this region to TOP, in Uboot, we run the followed command to burn the OTP: MX28 U-Boot -> sf probe 2:0 MX28 U-Boot -> sf set_config_reg 0x04   To boot the i.MX28 EVK board from SPI2 NOR flash, the BM3~0 should be 0010.   In this example, we only used the JFFS2 file system. To support the UBIFS, there is a known issue, that the UBIFS will use vmalloc to alloc memory, and if SPI driver used the DMA, kernel will halt with error "kernel BUG at arch/arm/mm/dma-mapping.c:409!".   For 11.09.01 BSP, the default MFGTool rootfs "initramfs.cpio.gz" will be bigger than 4MB, but in i.MX28 bootlets code, the BSP only set ramdisk to 4MB, so we need modify this limitation for MFGTool.   Use command "./ltib -p imx-bootlets -m prep" to get the bootlets code, modify "ltib/rpm/BUILD/imx-bootlets-src-11.09.01/linux_prep/core/setup.c", function setup_initrd_tag(), change from "params->u.initrd.size =  0x00400000;" to "params->u.initrd.size =  0x00500000;". Modify "ltib/rpm/BUILD/imx-bootlets-src-11.09.01/updater.bd" and "updater_ivt.bd", change from "load 0.b    > 0x40800000..0x40c00000;" to "load 0.b    > 0x40800000..0x40d00000;".   Now the MFGTool rootfs size can be 5MB.   2013-05-09: Updated hardware rework: On iMX28 EVK board, rework J89 as followed and mount R320,R321,R322 and C178. MX28 U49 Pin1 /CS <-> NOR Pin7 CS# MX28 U49 Pin2  D0 <-> NOR Pin8 SI/IO1 MX28 U49 Pin5 DIO <-> NOR Pin15 SI/IO0 MX28 U49 Pin6 CLK<-> NOR pin 16 SCK.

Hardware solution: when iMX28 was reboot, reset the SPI NOR too, the SPI NOR will work in 3 bytes address mode as default. Software solution: In kernel SPI NOR driver, always switch SPI NOR to 3 bytes address mode after each SPI NOR access, and switch to 4 bytes address mode before each access. There is no such issue if the SPI NOR size is less than 32MB.

Flashing Kernel and Root File System using RedBoot Creating an image A kernel image and a root file system can be created using All Boards LTIB or compiling the kernel and setting the correct set of files. Create a root file system image from a set of files converting the files to a jffs2 file system. For this, install the package mtd-tools. In Ubuntu type apt-get install mtd-tools For making an root file system for flash, use the jffs2 file system like: mkfs.jffs2 -r rootfs -e 0x20000 -s 0x800 –n -o rootfs.jffs2 Where rootfs/ is the original set of file for the file system and rootfs.jffs2 is the output image file. Flashing Some connections errors can be avoided by Configuring RedBoot. The process below uses TFTP to copy the files between host and target. See All Boards TFTP for detail in configurations. Copy the kernel image and the root file system image to the TFTP dir. For example, in LTIB dir, type sudo cp ./rootfs/boot/zImage /tftpboot sudo cp rootfs.jffs2 /tftpboot/ Where /tftpboot is the dir configured for TFTP The next steps are performed in a Minicom session, and happens on the board. Formatting the flash: Format the flash redboot> fis init -f Make a Bad Block Table redboot> nand scan Flashing kernel Load kernel image (zImage) using the command below. Remember to modify the host IP address: redboot> load -r -b 0x100000 /tftpboot/zImage -h 10.29.244.99 The address 0x100000 is used as a temporary location Create the kernel at the right address (0x100000, for IMX27PDK) redboot> fis create -f 0x100000 kernel Flashing root file system Load root file system image (rootfs.jffs2) to the temporary address. Remember to modify the host IP address: redboot> load -r -b 0x100000 /tftpboot/rootfs.jffs2 -h 10.29.244.99 Create the root file system in the right address (0x600000, for IMX27PDK) redboot> fis create -f 0x600000 root Testing This step can be omitted! You can now load your kernel in the flash by typing: fis load kernel To know if the root file system written in the flash was correctly saved, execute the NFS file system and mount the flash. For load the the root file system by NFS, type: exec -c "noinitrd console=ttymxc0,115200 root=nfs nfsroot=<server_ip>:<root_path_on_server> ip=dhcp" Wait the system go up, then mount the flash at /mnt. Reminde that the flash has a jffs2 file system. mount -t jffs2 /dev/mtdblock4 /mnt ls /mnt List the /mnt contents. The output must be the right file system. For testing root file system on NAND, type exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock4 rw rootfstype=jffs2 ip=dhcp" Modifying the initial script Reset the board and press CTRL-C. Type fc to modify the configurations and insert the initialization script. RedBoot> fc Run script at boot: true Boot script: Enter script, terminate with empty line >> fis load kernel >> exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock4 rw rootfstype=jffs2 ip=dhcp" >> Boot script timeout (1000ms resolution): 1 Use BOOTP for network configuration: false Gateway IP address: 10.29.241.254 Local IP address: 10.29.241.6 Local IP address mask: 255.255.254.0 Default server IP address: 10.29.244.99 Board specifics: 0 Console baud rate: 115200 Set eth0 network hardware address [MAC]: false GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false Update RedBoot non-volatile configuration - continue (y/n)? y ...
