ls1028ardb yocto-sdk build problems

[mclifford]

Hi,

I'm trying to follow the instructions here:

https://github.com/nxp-qoriq/yocto-sdk

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.

Regards

You also could use Debian flexbuilder Linux SDK to use Debian Linux OS.
