Suggest O/S:Ubuntu 18.04 or later.

Please comment out content to the local.conf to avoid the error during building the SDL.

#PACKAGECONFIG_append_pn-qemu-native = " sdl"
#PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

Storage: Please make sure the capacity of your storage has 300GB or bigger space.

RAM: Please make sure the physical memory + swap has 16GB or bigger capacity.

Procedure

Step 1. Install Host packages:

Essential Yocto Project host packages:

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \ 
build-essential chrpath socat libsdl1.2-dev

i.MX layers host packages for a Ubuntu 12.04 or 14.04 host setup are:

$ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html \
docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils \ 
libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidoc

Step 2. Insalling the repo utility:

Create the bin folder in the home directory:

$ mkdir ~/bin (this step may not be needed if the bin folder already exists)
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo 
$ chmod a+x ~/bin/repo

Step 3. Add the following line to the .bashrc file to make sure the ~/bin folder is in the PATH.

export PATH=~/bin:$PATH

Step 4. Ensure the git is properly set up by commands below:

$ git config --global user.name "Your Name" 
$ git config --global user.email "Your Email" 
$ git config --list

Step 5. Download the i.MX Yocto Project Community BSP recipe layers:

$ mkdir imx-yocto-bsp 
$ cd imx-yocto-bsp 
$ repo init -u https://github.com/nxp-imx/imx-manifest -b \
imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml
$ repo sync

Step 6. Unzip the Recipe for building Yocto Linux for NX8MM-35 to the file ‘imx-yocto-bsp”

Step 7. Create the setup environment by command below (You could change the file name as you want)

$ DISTRO=fsl-imx-xwayland MACHINE=dm446 source fsl-setup-release.sh -b \ 
build-dmp

Please input “y” when the EULA confirmation pop out.

Step 8. Edit conf/local.conf file and add the content below at the bottom:

CORE_IMAGE_EXTRA_INSTALL += "chromium-ozone-wayland"

IMAGE_INSTALL_append += " \
    openssh-sftp-server \
    ppp \
    rng-tools \
    glibc-gconv-utf-16 \
    expand-rootfs \
    opkg \
    cifs-utils \
    gdbserver \
"

Step 9. Edit conf/bblayers.conf file and add the content below at the bottom:

BBLAYERS += " ${BSPDIR}/sources/meta-custom-dmp "

Step 10. Run the command below.

$ bitbake fsl-image-qt5-validation-imx

The system will start to download and install source code, patch file, and compilation

If there is a imx-gpu-sdk compiling error:

Copy /imx-yocto-bsp/build-dmp/tmp/work/dm446-poky-linux/devil/1.8.0-r0/package/usr/lib/*

to imx-yocto-bsp/build-dmp/tmp/work/aarch64-mx8mm-poky-linux/imx-gpu-sdk/5.3.0-r0/recipe-sysroot/lib64

How to install the image file by UUU.

After implemented bitbake fsl-image-qt5-validation-imx, it will generate an image file and be stored in the file under build-dmp/tmp/deploy/images/dm446.

In the build-dmp/tmp/deploy/images/dm446 file, we’ll need the file below for the image restoration.

1. fsl-mage-qt5-validation-imx-dm446.sdcard.bz2
2. imx-boot-dm446-sd.bin-flash_evk

↵Input command to get the image file - fsl-mage-qt5-validation-imx-dm446.sdcard (In this file, there are packaged kernel and rootfs):

$ bzip2 -d fsl-mage-qt5-validation-imx-dm446.sdcard.bz2 

Download the UUU.auto sample:https://ftp.icop.com.tw/share/RJ3PjTI8

If you have requirement to change the file name, please follow the steps below to change your file name (You could choose not changing the file name.)

SDP: boot -f XXX.bin-flash_evk
SDPU: write -f XXX.bin-flash_evk -offset 0x57c00
SDPS: boot -f XXX.bin-flash_evk
SDPV write -f XXX.bin-flash_evk -skipspl
FB: flash bootloader XXX.bin-flash_evk 
XXX.bin-flash_evk = imx-boot-dm446-sd.bin-flash_evk  

FB: flash -raw2sparse all XXX.image  
XXX.image = fsl-mage-qt5-validation-imx-dm446.sdcard 

After you have set your own file name, you could input the command below to install the Yocto Linux
