You already know. Your source code is one week old now, so please, update it (or should I say 'sync' it?)! Get used to update your BSP layers. Recipe Is the name of file that determinates how a package should act. For example, the version, where it is the mainstream repo, how to build, install, link. etc. Kernel For meta-fsl-arm the kernel recipes are under meta-fsl-arm/recipes-kernel/linux (take a look here meta-fsl-arm - Layer containing Freescale ARM hardware support metadata) For meta-fsl-arm, there are 3 kernel recipes: linux-fslc_3.8.bb  --> kernel mainline (from kernel.org) linux-imx_2.6.35.3.bb  --> kernel from FSL, for imx5x and imx28 linux-imx_3.0.35.bb --> kernel from FSL for imx6 Take the linux-imx for imx6 as an example meta-fsl-arm - Layer containing Freescale ARM hardware support metadata The recipe determinates: what´s the compatible machine for this linux version (mx6) what´s the commit ID for the head of this code (SRCREV) (MX6DL and MX6SL have different source code) what´s the patches for the mx6 boards (SRC_URI). In order to see where the source code is cloned from, you need to go to .inc file meta-fsl-arm - Layer containing Freescale ARM hardware support metadata SRC_URI = "git://git.freescale.com/imx/linux-2.6-imx.git \            file://defconfig \ " it´s from git.freescale.com. In addition, there is a defconfig file added on SRC_URI. There is a defconfig file for every board, on every Linux revision. Some defconfigs are shared for more than one board (for example, every mx6 board), and some Linux version are not compatible for some boards (for example, imx53 is only compatible with 2.6.35). During a bitbake linux-imx, a temp folder will be created under build/tmp/armv7-imx6....../linux-imx, with code from git, patches and defconfig. Then bitbake takes that defconfig and configure the kernel, built it, and deploy it. So, in order to change the kernel configuration (make menuconfig) you must replace your defconfig file from meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6 How to change kernel configuration Create the new defconfig Copy it to meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6 (or the right folder for your board/kernel) $ bitbake -c cleansstate linux-imx $ bitbake linux-imx (if you want only the kernel image) $ bitbake fsl-image-gui (if you want to generate a complete image using the new kernel) How to make menuconfig with yocto $ bitbake -c menuconfig linux-imx will generate a config file on tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.0.35-r33.10/git/.config The complete step by step to change the kernel configuration $ bitbake -c menuconfig linux-imx (change anything) $ cp tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.0.35-r33.10/git/.config ../sources/meta-fsl-arm/recipes-kernel/linux/linux-imx-3.0.35/mx6/defconfig $ bitbake -c cleansstate linux-imx $ bitbake fsl-image-gui The uImage will be under tmp/deploy/image In order to replace only uImage binary into one ready sdcard: $sudo cp tmp/deploy/image/uImage-imx6-XXX.bin /media/user/Boot imx6/uImage Kernel Mainline - kernel.org In order to use kernel mainline instead of linux-imx. Please add the following code to your conf/local.conf PREFERRED_PROVIDER_virtual/kernel = "linux-fslc" Make sure the desired board is supported by kernel.org. In order to take and build kernel mainline manually, please see https://community.freescale.com/docs/DOC-95017 Final points It´s not a simple task, I know. Yocto is not the best tool for use to develop and customize kernel during development stage. It is easier to use an external toolchain (bitbake meta-toolchain). Once the kernel development, or customization, is done, the changes can be integrated in the Yocto so it is managed for production use. I like to have a copy of kernel source code cloned on my machine directly from git.freescale.com, then I can re-configure it, rebuild it, apply some patches, make changes, and build it manually - any way I want it. So, I only change kernel using yocto when I know the bug and I know how to fix it, and I have the patch. (and this is the way I like to work) Although this is how to configure (and even patch) kernel (if you want to patch kernel, follow the example in the recipes) If you face any error, please, let me know. I tested the steps and it worked, but I´m using an Ubuntu machine, not a virtual machine (and I´m not sure how -c menuconfig will act in a virtual machine). Go to Yocto Training - HOME Go to Task #4 - Deploy and test

1. To setup the Yocto environment, from the BASE folder run fsl-community-bsp $ . setup-environment build 2. Build the toolchain build $ bitbake meta-toolchain # Other toolchains: # Qt Embedded toolchain build: bitbake meta-toolchain-qte # Qt X11 toolchain build: bitbake meta-toolchain-qt 3. Install it on your PC build $ sudo sh \   tmp/deploy/sdk/poky-eglibc-x86_64-arm-toolchain-<version>.sh 4. Setup the toolchain environment build $ source \   /opt/poky/<version>/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi 5. Get the Linux Kernel's source code. $ git clone git://git.freescale.com/imx/linux-2.6-imx.git linux-imx $ cd linux-imx 6. Create a local branch linux-imx $ BRANCH=imx_3.0.35_4.0.0 # Change to any branch you want,   # Use 'git branch -a' to list all linux-imx $ git checkout -b ${BRANCH} origin/${BRANCH} 7. Export ARCH and CROSS_COMPILE linux-imx $ export ARCH=arm  linux-imx $ export CROSS_COMPILE=arm-poky-linux-gnueabi- linux-imx $ unset LDFLAGS 8. Choose configuration and compile linux-imx $ make imx6_defconfig  linux-imx $ make uImage  9. To Test your changes, copy the `uImage` into your SD Card linux-imx $ sudo cp arch/arm/boot/uImage /media/boot 10. If case you want your changes to be reflected on your Yocto Framework, create the patches following the document i.MX Yocto Project: How can I patch the kernel?

Introduction The Intel® Neural Compute Stick 2 (Intel® NCS 2) is Intel’s newest deep learning inference development kit. Packed in an affordable USB-stick form factor, the Intel® NCS 2 is powered by latest VPU (vision processing unit) – the Intel® Movidius™ Myriad X, which includes an on-chip neural network accelerator called the Neural Compute Engine. With 16 SHAVE cores and a dedicated hardware neural network accelerator, the NCS 2 offers up to 8x performance improvement+ over the previous generation. Ref: https://software.intel.com/en-us/articles/run-intel-openvino-models-on-intel-neural-compute-stick-2   The NCS 2 officially supported hardware platform is x86 PC and Raspberry Pi. In this guide, we will introduce how to implement in i.MX8MQ. Please see attached guide for more details.

The attched package includes mbedTLS and DCP/RNGB driver based on SDK2.2, you can apply it on Windows Installer: MCUXpresso SDK2.2 for i.MX 6ULL 1. fsl_dcp.c/fsl_dcp.h and fsl_rngb.c/fsl_rngb.h under devices\MCIMX6Y2\drivers is dcp ang rngb driver. 2. Some files under middleware\mbedtls-2.4.0\port\sdk are porting code for mbedTLS 3. Example codes are under folder boards\evkmcimx6ull which have driver example and mbedTLS example. 4, The patch package only support IAR toolchain. 5, Due to SDK don't support allocation of non-cachable memory dynamically, so some static non-cachable bufferes in sdk_mbedtls.c is used for shared memory with hareware. So mbedTLS don't be used for multi-thread concurrently.

Check new updated version for with Morty here Step 1 : Get iMX Yocto AVS setup environment Review the steps under Chapter 3 of the i.MX_Yocto_Project_User'sGuide.pdf on the L4.X LINUX_DOCS to prepare your host machine. Including at least the following essential Yocto packages $ sudo apt-get install gawk wget git-core diffstat unzip texinfo \   gcc-multilib build-essential chrpath socat libsdl1.2-dev u-boot-tools Install the i.MX NXP AVS repo Create/Move to a directory where you want to install the AVS yocto build enviroment. Let's call this as <yocto_dir> $ cd <yocto_dir> $ repo init -u https://source.codeaurora.org/external/imxsupport/meta-avs-demos -b master -m imx7d-pico-avs-sdk_4.1.15-1.0.0.xml Download the AVS BSP build environment: $ repo sync Step 2: Setup yocto for Alexa_SDK image with AVS-SETUP-DEMO script: Run the avs-setup-demo script as follows to setup your environment for the imx7d-pico board: $ MACHINE=imx7d-pico DISTRO=fsl-imx-x11 source avs-setup-demo.sh -b <build_sdk> Where <build_sdk> is the name you will give to your build folder. After acepting the EULA the script will prompt if you want to enable: Sound Card selection The following Sound Cards are supported on the build: SGTL (In-board Audio Codec for PicoPi) 2-Mic Conexant The script will prompt if you are going to use the Conexant Card. If not then SGTL will be assumed as your selection Are you going to use Conexant Sound Card [Y/N]? Install Alexa SDK Next option is to select if you want to pre-install the AVS SDK software on the image. Do you want to build/include the AVS_SDK package on this image(Y/N)? If you select YES, then your image will contain the AVS SDK ready to use (after authentication). Note this AVS_SDK will not have WakeWord detection support, but it can be added on runtime. If your selection was NO, then you can always manually fetch and build the AVS_SDK on runtime. All the packages dependencies will be already there, so only fetching the AVS_SDK source code and building it is required. Finish avs-image configuration At the end you will see a text according with the configuration you select for your image build. Next is an example for a Preinstalled AVS_SDK with Conxant Sound Card support and WiFi/BT not enabled. ==========================================================   AVS configuration is now ready at conf/local.conf             - Sound Card = Conexant                                     - AVS_SDK pre-installed                                       You are ready to bitbake your AVS demo image now:               bitbake avs-image                                        ========================================================== Step 3: Build the AVS image Go to your <build_sdk> directory and start the build of the avs-image There are 2 options Regular Build: $ cd <yocto_dir>/<build_sdk> $ bitbake avs-image With QT5 support included: $ cd <yocto_dir>/<build_sdk> $ bitbake avs-image-qt5 The image with QT5 is useful if you want to add some GUI for example to render DisplayCards. Step 4 : Deploying the built images to SD/MMC card to boot on target board. After a build has succesfully completed, the created image resides at <build_sdk>/tmp/deploy/images/imx7d-pico/ In this directory, you will find the imx7d-pico-avs.sdcard image or imx7d-pico-avs-qt5.sdcard, depending on the build you chose on Step3. To Flash the .sdcard image into the eMMC device of your PicoPi board follow the next steps: Download the bootbomb flasher Follow the instruction on Section 4. Board Reflashing of the Quick Start Guide for AVS kit to setup your board on flashing mode. Copy the built SDCARD file $ sudo dd if=imx7d-pico-avs.sdcard of=/dev/sd bs=1M && sync $ sync Properly eject the pico-imx7d board: $ sudo eject /dev/sd NXP Documentation Refer to the Quick Start Quide for AVS SDK to fully setup your PicoPi board with Synaptics 2Mic and PicoPi i.mx7D For a more comprehensive understanding of Yocto, its features and setup; more image build and deployment options and customization, please take a look at the i.MX_Yocto_Project_User's_Guide.pdf document from the Linux documents bundle mentioned at the beginning of this document.

iMX8QXP/iMX8QM have hardware JPEG decoder: The JPEG-D-X core. This is the example code to use this hw decoder in M4 SDK to decode JPEG files. M4_JPEG_DECODER_SDK_2.5.1.7z The attached "rear_view_camera_jpegdec.tar.bz2" is the updated source code for "SDK\boards\mekmimx8qx\demo_apps\rear_view_camera". It is based on SDK 2.5.1 for iMX8QXP MEK. The "rear_view_camera_jpegdec.patch" is the modified code, it hasn't included the added "fsl_jpeg_dec.c" and "fsl_jpeg_dec.h".   The testing used two 256*256 JPEG files, they are RGB color space. We used followed commands to build them into flash.bin: ./mkimage_imx8 -soc QX -rev B0 -append ahab-container.img -c -scfw scfw_tcm.bin -m4 m4_rear_view_camera.bin 0 0x34FE0000 --data demo_rgb.jpg 0x84000000 --data demo_rgb2.jpg 0x84008000 -out flash.bin   If customer need change the JPEG resoluion, they can change them in file "fsl_jpeg_dec.h", APP_JPEG_SIZE_OF_KB is the JPEG file length in memory, aligned in KB.   #define APP_JPEG_WIDTH (256) #define APP_JPEG_HEIGHT (256) #define APP_JPEG_SIZE_OF_KB (32) #define APP_JPEG_FORMAT JPEG_RGB #define APP_JPEG_BUFFER (0x84000000)   To created RGB format JPEG file from RGB data, the customer can use linux unit test application "/unit_tests/JPEG/encoder_test.out". M4_JPEG_DECODER_WINDOW_MODE_SDK_2.5.1.7z Based on JEPG decoder, added DPU CSC support and render JEPG decoded video in overlay window. The architecture is followed: NXP logo is put in FetchLayer0 with RGB565 format, after LayerBlend0, it will be the prim layer for LayberBlend1 (FetchLayer0 can't be used as prim layer for LayerBlend), the JPEG decoder output is put to FetchDecoder0. RGB888 format, and it will be resize to 640*480, and put to x=100, y=100 of the display. (Only the sec layer of LayerBlend can be window mode). Some limitation for layer selection in LayerBlend:

For IMX8QM and iMX8QXP, the DDR config is in SCFW porting kit with DDR script. After boot, for iMX8QM, the LPDDR4 clock is set to 1.6GHz, and for iMX8QXP, after boot, the LPDDR4 clock is set to 1.2GHz. Their clock source is a HPPLL (High Performance PLL) , the HPPLL work frequency range is 1.25GHz to 2.5GHz. But for some product, due to some EMC signal test requirement, sometimes we need adjust the DDR clock a little, the attached patches can be used as reference to do such test. iMX8QM:    HPPLL = 1600MHz, DRC clock = 800MHz, DDR clock = 1600MHz. iMX8QXP:    HPPLL = 2400MHz, DRC clock = 600MHz, DDR clock = 1200MHz. After applied attached two reference patches in SCFW porting kit, they will be: iMX8QM:    HPPLL = 1584MHz, DRC clock = 792MHz, DDR clock = 1584MHz. iMX8QXP:    HPPLL = 2388MHz, DRC clock = 597MHz, DDR clock = 1194MHz. If you want to try set other clock frequency for iMX8QM, you can change the followed lines: ......  uint32_t rate2 = SC_792MHZ;  /* DRC clock */ ......  DSC_AIRegisterWrite(0x12,0,4,0x00000084);  /* DRC_0: (24M*0x84/2) = 1584M, valid dividder: 0x68~0xD0 */  //This is the HPPLL frequency ......  DSC_AIRegisterWrite(0x28,0,4,0x00000084);  /* DRC_1: (24M*0x84/2) = 1584M, valid dividder: 0x68~0xD0 */  //This is the HPPLL frequency ...... If you want to try set other clock frequency for iMX8QXP, you can change the followed lines: ......  uint32_t rate2 = 597000000U;  /* DRC clock */ ......  DSC_AIRegisterWrite(0x24,0,4,0x000000C7);  /* DRC_0: (24M*0xC7/2) = 2388M, valid dividder: 0x68~0xD0 */  //This is the HPPLL frequency ......

In defaut Linux BSP, NXP implemented LVDS to HDMI(it6263) and MIPI-DSI to HDMI(adv7535) bridge chip drivers. And these drivers need read the EDID from display, then apply the timing parameters to DRM driver. But for the use case that bridge chip -> Serializer -> Deserializer -> LCD Panel use case, there is no EDID. The attached are reference patches for such use case, it combined the bridge chip to panel directly, and no EDID is needed. The patches are tested on iMX8QXP MEK with bridge chip + panel mode, both of them can see the fb0 device under /sys/class/graphics/ folder, also can see card under  /sys/class/drm/. Display works fine with DTS selected 720P panel mode. [2020-06-24]: Add patches for L4.14.98 kernel: Android_Auto_P9.0.0_GA2.1.0_Kernel_No_EDID_IT6263.patch L4.14.98-iMX8QXP-MEK-ADV7535-MIPI-DSI-to-HDMI-bridge-chip-com.patch
