ls1028ardb yocto-sdk build problems

mclifford — Wed, 01 Jul 2026 10:18:01 GMT

Hi,

I'm trying to follow the instructions here:

to build the OS and SDK images for the LS1028ARDB

It appears that walnascar is the default branch, but the build fails if i use the instructions at the link above.

mkdir yocto-sdk
cd yocto-sdk
repo init -u https://github.com/nxp-qoriq/yocto-sdk -b walnascar
repo sync --force-sync
. ./setup-env -m ls1028ardb
bitbake fsl-image-networking

this fails with 3 errors:
- sysvinit installation errors
- dtc-native compile errors
- util-linux-native compile errors

I've also tried the instructions from this document which fail in a different way even if you work around the incorrect instructions (the specified "ls-image-desktop" does not exist):

https://docs.nxp.com/bundle/UG10081_LLDP_L6.1.55_2.2.0/page/topics/how_to_download_flexbuild.html

I also found the flexbuild option, and followed the instructions here:

https://github.com/nxp/flexbuild

git clone https://github.com/NXP/flexbuild.git
cd flexbuild
make docker
make ls1028ardb_defconfig
make all

this also fails with the error:

W: binfmt_misc not found in /proc/mounts -- not mounted

What are the correct instructions for building the OS image and SDK?

Regards

Matt

after posting this, I discovered Debian Linux SDK User Guide which has some pre-requisites not listed in the flexbuild readme.md. This appears to allow me to generate a Debian based image for the LS1028ARDB.

What are the instructions for generating an SDK in a similar way to the Yocto environment? or do you recommend a standard cross-compiler?

Is the Debian solution now the recommended OS for this platform? Yocto feels more appropriate for an embedded system.

Hi,

Thanks for the input but the walnascar-lsdk branch fails with similar errors as the walnascar branch i described above.

This is the output for
bitbake -k fsl-image-networking-full

Hi,

Thanks for the reply, it turns out it was my fault, I was using the wrong version of ubuntu and stupidly ignored the warning in the yocto output.

I switched to using a 24.04 dev container and following the instructions in:

Layerscape Software Development Kit User Guide for Yocto: UG10374.pdf

to do the build and that worked fine.

Regards

Matt
