Hi, help me!

I have some problems building the system 4.19.35 for imx6ull when I using the instructions i.MX_Yocto_Project_User's_Guide. 

I'm using ubuntu 18.04.
I follow these steps:
1. Installed 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

2. I'm setting up a repo package:

mkdir ~/bin

curl > ~/bin/repo

chmod a+x ~/bin/repo

sudo apt-get install repo

3. I'm setting up a Yocto project

git config --global "Your Name"
git config --global "Your Email"
git config –list
mkdir imx-yocto-bsp
cd imx-yocto-bsp
repo init -u -b imx-linux-warrior -m imx-4.19.35-1.1.0.xml
repo sync

4.After that, I set up a build configuration

MACHINE=imx6ull14x14evk DISTRO=fsl-imx-fb source -b build_ull

5. Started build

bitbake imx-image-multimedia

Thus, I got a tree of devices and a system image that are in the folder tmp/deploy/images/imx6ull14x14evk

6. After which I change the device tree, for the test I changed lsd in the file:




7. I start build again

bitbake imx-image-multimedia

8. Checking files in


but they have not changed and in the terminal I see the following:

NOTE: Tasks Summary: Attempted 5720 tasks of which 5720 didn't need to be rerun and all succeeded.


What am I doing wrong?


I also tried using commands:

bitbake imx-image-multimedia -с fetch

bitbake imx-image-multimedia -с deploy

bitbake imx-image-multimedia -c compile -f


but it did not bring the desired result.
