Many times I came across one issue while using Redlib in MXUXpresso IDE project. I like to provide some guidance here to match the proper solution that can help others. Problem Statement : printf or sprintf doesn't print anything or printing random characters while using Redlib library. Reason : When you are creating your project you may ask to choose the c/c++ library setting to select either of the c libray provided by IDE in Advanced project setting wizard. If you have not checked the option "Redlib: Use floating point version of printf" (which will use the floating-point variant of printf) have tried to print the floating point value, You will end up with the problem mentioned above. Solution : You need to enable the floating support by modifying some preprocessor directives in "Defined symbols (-D)" wizard of your project. Path :  Your Project > properties > C/C++ Build > Setiings > Tool Settings > MCU C Compiler > Preprocessor. These are: PRINTF_FLOAT_ENABLE - keep the directive value to "1" SCANF_FLOAT_ENABLE - keep the directive value to "1" CR_INTEGER_PRINTF - Undefine/Remove this directive Click on Apply and close. That is it. Now you will have your expected prints for floating point values in your debugger console.

This is a series of documents that intend to help you grasp he concept of the System Controller Unit (SCU) / System Controller Firmware (SCFW).    Getting started Power management service  Resource management service Pad configuration service Timer service Miscellaneous service   Other Useful resources: https://community.nxp.com/docs/DOC-344684 (2019) i.MX 8 System Controller Unit and System Controller Firmware Overview (2018) Clusters & Infotainment: Introduction to the i.MX 8 System Controller Unit (2017 Slightly outdated, for correct boot sequence go to Chapter 5 System Boot of the Reference Manual) System Controller Firmware command line utility for QNX and Linux You can get the latest System Controller Firmware Porting kit from the i.MX Software and development webpage: The porting kit contains documentation and allows you to build the SCFW from source and do modifications to the board dependent parts: The API documents explain the System Controller Firmware API syntax and it has a section for introduction and general overview of the system. The port document contains information on what each board component function does and the overall process of porting the SCFW.

This documents describes how to add the NFC support to i.MX8M mini evk running Android Pie. Hardware setup: The i.MX8M mini evk (see i.MX 8M Mini Evaluation Kit | NXP) featuring Raspberry Pi compliant connector, the OM5578/RPI PN7150 demo kit can be used to perform this porting (see NFC Development Kits for Arduino and more|NXP). However a small modification must be done because some of the signals required by PN7150 are not mapped to i.MX8M mini expansion connector pins. OM5578 IRQ signal must be mapped to Raspberry Pi connector pin #19 and OM5578 VEN signal must be mapped to Raspberry Pi connector pin #21. See below a picture of the modification: Then, the two boards can fit together as shown in the picture below: Quick start using demo image: The demo image including support for PN7150, is based on Android P9.0.0 Pie (P9.0.0_1.0.0, 4.14 kernel) i.MX software release (see i.MX Software | NXP). Related documentation can be downloaded from here: https://www.nxp.com/docs/en/supporting-information/android_p9.0.0_1.0.0-ga_docs.zip. Just flash the demo image (downloaded from here:https://www.nxp.com/lgfiles/updates/NFC/ANDROID_P9-0-0_PN7150_IMAGE_8MMEVK.zip) following guidelines from i.MX_Android_Quick_Start document (part of Android P9.0.0_1.0.0 Documentation package mentioned above). The NFC support is then included in the device settings, as shown in below screenshot of the device: Approaching the NFC tag, provided as reference in the OM5578 demo kit, to the NFC Antenna will trigger a sound notification: Unfortunately the Android demo image doesn't embed a web browser, so it won't be automatically open when the NFC tag content (an URL to the demo kit web page) is read. Otherwise (if a web browser is installed) you could see such page opening on the device: Adding PN7150 support to imx-android-pie release: If you wish to add PN7150 support to your imx-android-pie environment, just apply the patches (imx-p9.0.0_1.0.0-ga_pn7150_patches.tar.gz file attached) from the ${MY_ANDROID} source code root folder (refer to i.MX_Android_User_Guide document part of Android P9.0.0_1.0.0 Documentation package mentioned above).  $ patch -p1 -d device/fsl/ <device_fsl.patch  $ patch -p1 -d packages/apps/Nfc <packages_apps_Nfc.patch  $ patch -p1 -d hardware/nxp/nfc <hardware_nxp_nfc.patch  $ patch -p1 -d vendor/nxp <vendor_nxp.patch  $ patch -p1 -d vendor/nxp-opensource/kernel_imx/ <vendor_nxp-opensource_kernel_imx.patch When building, the PN7150 support will then be included to the android image, as shown in the demo image described above. Reference: This porting have been done (demo image and patches creation) following guidelines provided in AN11690_NXP-NCI_Android_Porting_Guidelines document.

The native Yocto not support chinese, so need to add chinese font . The first step should download Chinese font  files such as  MSYHMONO.ttf and DroidSansFallback.ttf.Then copy fonts files to /usr/share/fonts/truetype and run command  fc-cache .update font cache. use fc-list :lang=zh can see which Chinese fonts are installed:          /usr/share/fonts/truetype/MSYHMONO.ttf: Microsoft YaHei Mono:style=Regular          /usr/share/fonts/truetype/DroidSansFallbackFull.ttf: Droid Sans Fallback:style=Regular The secend step is to change default fonts. In weston-terminal.c we can see:           3119   weston_config_section_get_string(s, "font", &option_font, "mono");           3120   weston_config_section_get_int(s, "font-size", &option_font_size, 14);  weston-terminal default use mono font.Just to modify /etc/fonts/fonts.conf           <edit name="family" mode="assign" binding="same">                       <string>monospace</string> to   <string>Microsoft YaHei Mono</string> or <string>Droid Sans Fallback</string> could display Chinese character   But it have some problem such like as :   the left use Microsoft YaHei Mono font the Chinese character is overlapping ,the right use Droid Sans Fallback font is en-font could not display. If you have a better way to welcome a message！

This document describes the i.MX 8QXP MEK mini-SAS connectors features on Linux and Android use cases, covering the supported daughter cards, the process to change Device Tree (DTS) files or Boot images, and enable these different display options on the board.

For imx8QM, The manufacture mode is supported on SD2 which is powered by LDO2 of PMIC2 on MEK board. LDO2 of PMIC2 on MEK board is OFF by default. (LDO2 of PMIC1 is on by default) So manufacture mode is NOT working on the imx8QM MEK board. the solution would be: 1. schematic change Exchange the power supply(VCC_LDO_SD) and USDHC_VSELECT signal of SD2 and SD1. between PMIC2 (U23) and PMIC 1(U10). so that, the VCC_LDO_SD2) and USDHC2_VSELECT will be located on where VCC_LDO_SD1) and USDHC1_VSELECT are origonally.  and VCC_LDO_SD1 and USDHC1_VSELECT will be located on where VCC_LDO_SD2) and USDHC2_VSELECT are origonally.  SD1 will no longer be supported as the boot resource, instead SD2 will be. anyway you still can connect a WIFI to SD1 , becasue the power supply can be turned on after software booting up. 2. Modify the default fuse of PMIC, whcih is to enable LDO2 of PMIC2 by default.     please contact your local FAE and Sales for this.  we may add notification in the reference schematic and HW development guild in the future.

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

Basic Linear Algebra Subprograms (BLAS) is a specification that prescribes a set of low-level routines for performing common linear algebra operations such as vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication. OpenBLAS is an optimized BLAS library which is uesd for deep learning accelerator in Caffe/Caffe2. I enable it in Yocto (Rocko) by adding bb file. And I build on i.MX6QP, i.MX7ULP and i.MX8MQ and also run its test example successfully. You can find test example(openblas_utest) under folder image/opt/openblas/bin of OpenBLAS work directory. Currently, version 0.3.0 is supported in the bb file. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ update to v 0.3.6 and enable mutli-thread by set USE_OPENMP=1 and USE_THREAD=4 when compiling this library.

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
