- For PN8M-C (WM8962): https://ftp.icop.com.tw/share/FYtqsTfk
Check the compiling method on the open document form NXP:
Suggest O/S:Ubuntu 20.04 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 rsync curl zstd lz4 libssl-dev
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 and dowlonad Freescale Community BSP
$ 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-kirkstone -m imx-5.15.71-2.2.0.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
or
at the recipe, copy and replace “Sources” folder to “imx-yocto-bsp” and bblayers.conf & local.conf to “/im-yocto-bsp/build-dmp/conf/”.
CORE_IMAGE_EXTRA_INSTALL += "chromium-ozone-wayland" IMAGE_INSTALL:append += " \ expand-rootfs \ linux-firmware \ Pulseaudio \ "
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
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-img-full-dm421-XXXXXXXXXXXXX.rootfs.wic.zst 2. imx-boot-dm421-sd.bin-flash_evk
Input command to get the image file - imx-image-full-dm395e.wic (In this file, there are packaged kernel and rootfs):
$ zstd -d imx-img-full-dm421-XXXXXXXXXXXXX.rootfs.wic.zst

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