Hi @ching-julo 

Please check the permission and for the ,zip file, and if zip file and uuu.auto are at the same directory.  more details about how to flash and tool, you can refer to Release 1.4.232 · NXPmicro/mfgtools · GitHub

Best regards

Hi @sml310511029 

Can you check on your side which node not found? 

and Did you flash boot image that is from our prebuilt image? 

Best regards

Hi! @Harvey021 

I'm new to this board and the system. Could you teach me how to check which node that is no found?

All I have done so far was to follow the i.MX Yocto Project User's Guide:

$ 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 pzstd lz4c lz4

$ 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

export PATH=~/bin:$PATH

$ mkdir imx-yocto-bsp

$ cd imx-yocto-bsp

$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest-b imx-linux-honister -m imx-5.15.5-1.0.0.xml

$ repo sync

DISTRO=fsl-imx-xwayland MACHINE=imx8mp-lpddr4-evk source imx-setup-release.sh -b build

bitbake -k imx-image-full

Hi @sml310511029 

Be aware of you are building image by Yocto. 

several awareness for you,

Assumedly Git set up that you have completed as in the user guide.

$ git config --global user.name "Your Name"

$ git config --global user.email "Your Email"

$ git config --list

About "bitbake -k imx-image-full" that you performed. I'd recommend you don't use the parameter with "k", except that you have your own consideration of reasons. And what about you try to build relatively smaller image, those also listed in user guide.

Best regards

Harvey
