Check the compiling method on the open document form NXP:
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 cpio python python3 \ python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm
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. Change the python version under \user\bin\python and insall the repo utility:
Change the shortcut to python 2.7 to python 3.8 or later
$ /user/bin/python/python 2.7 change to $ /user/bin/python/python 3.8 // or later version
Create the bin folder in the home directory:
$ mkdir ~/bin $ sudo apt --yes install curl $ 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-zeus -m imx-5.4.70-2.3.6.xml $ repo sync
Step 6. Unzip the Recipe for building Yocto Linux for PN8M-090T 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=dm421 source imx-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 += " \ expand-rootfs \ linux-firmware \ "
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 imx-image-full
The system will start to download and install source code, patch file, and compilation
Panel control
Control brightness of back-light
echo 0 > /sys/class/backlight/32e10000.mipi_dsi.0/brightness echo 50 > /sys/class/backlight/32e10000.mipi_dsi.0/brightness echo 100 > /sys/class/backlight/32e10000.mipi_dsi.0/brightness
Touch calibration
#calibrator.sh has been put under /usr/bin by #recipe
How to install the image file by UUU.
After implemented bitbake imx-image-full, it will generate an image file and be stored in the file under build-dmp/tmp/deploy/images/dm421.
In the build-dmp/tmp/deploy/images/dm421 file, we’ll need the file below for the image restoration.
1. imx-image-full-dm421-XXXXXXXXXXXXXX.rootfs.wic.bz2 2. imx-boot-dm421-sd.bin-flash_evk
Input command to get the image file - imx-image-full-dm421-XXXXXXXXXXXXXX.rootfs.wic
(In this file, there are packaged kernel and rootfs):
$ bzip2 -d imx-image-full-dm421-XXXXXXXXXXXXXX.rootfs.wic.bz2

SDP: boot -f imx-boot-dm421-sd.bin-flash_evk
- This command will be run when use SPL
SDPU: delay 1000 SDPU: write -f imx-boot-dm421-sd.bin-flash_evk -offset 0x57c00 SDPU: jump
- This command will be run when ROM support stream mode
SDPS: boot -f imx-boot-dm421-sd.bin-flash_evk
- These commands will be run when use SPL and will be skipped if no spl
- if (SPL support SDPV)
