Recipe for building Yocto Linux for EBOX-IMX8MMINI

• For EBOX-IMX8MMINI (F version): https://ftp.icop.com.tw/share/83BXyu0v

Check the compiling method on the open document form NXP:

• https://ftp.icop.com.tw/share/0vEvaxHe

Suggest O/S:Ubuntu 20.04 or later.

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 install gawk wget git diffstat unzip texinfo gcc build-essential
chrpath socat cpio python3 python3-pip python3-pexpect xz-utils debianutils
iputils-ping python3-git python3-jinja2 python3-subunit zstd liblz4-tool file
locales libacl1

Step 2. Change the python version under \user\bin\python and Insall the repo utility:

Change the shortcut under /usr/bin to python 3.8. or later

$ sudo ln -sf /usr/bin/python3.8 /usr/bin/python

Use 
$ ls -l python
to check the python status: Python -> python3.8

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-scarthgap -m imx-6.6.36-2.1.0.xml
$ repo sync

Step 6. Create the setup environment by command below

DISTRO=fsl-imx-xwayland MACHINE=dm395 source imx-setup-release.sh -b build-dmp

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

Step 7. Unzip the Recipe for building Yocto Linux for EBOX-IMX8MMINI to the file ‘imx-yocto-bsp”

(Merge and replaced the same file in the source and build-dmp folder)

Step 8. 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/dm395e

In the build-dmp/tmp/deploy/images/dm395e file, we’ll need the file below for the image restoration.

1. imx-boot-dm395.bin-flash_evk
2. imx-image-full-dm395-xxxxxxxx.wic.zst

Input command to get the image file - imx-image-full-dm395e.wic (In this file, there are packaged kernel and rootfs):

$ zstd -d imx-image-full-dm395-xxxxxxxx.wic.zst

Download the UUU.auto sample:https://ftp.icop.com.tw/share/6oK-EhMl UUU application under Linux:https://github.com/nxp-imx/mfgtools/releases

1. dm395-241121.bin
2. dm395-241121.wic

If we name the file in the image file like above, we could make a auto file like below:

uuu_version 1.0.1
SDP: boot -f dm395-241121.bin
SDPU: delay 1000
SDPU: write -f dm395-241121.bin -offset 0x57c00
SDPU: jump
SDPS: boot -f dm395-241121.bin
SDPV: delay 1000
SDPV: write -f dm395-241121.bin -skipspl
SDPV: jump
FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev 2
FB: ucmd mmc dev 2 0
FB: flash -raw2sparse all dm395-241121.wic
FB: flash bootloader dm395-241121.bin
FB: ucmd if env exists emmc_ack; then ; else setenv emmc_ack 0; fi;
FB: ucmd mmc partconf 2 ${emmc_ack} 1 0
FB: done

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

uuu uuu.auto
