failed to build tensorflow on offline machine for imx8mp Scarthgap

greeran · ‎08-23-2025

Hi

I’m building the fsl-image-qt6 image for i.MX8MP with Scarthgap. I built it on an online machine and copied the downloads directory to the offline machine. I’ve successfully used this workflow many times before with other BSP releases (Kirkstone, Zeus, and others), so this isn’t my first offline BSP build.

However, when I try to build the same image on the offline machine, the build fails at tensorflow-lite-tools-native. It seems to attempt cloning extended third-party dependencies (protobuf, etc.), and the downloaded tar.gz files are not sufficient to satisfy it.

Has anyone come across this issue before? If so, what’s the recommended way to resolve it?

Thanks in advance

i delete all my build, download and sstate and rebuild from scratch. the build was long but successful. i then removed the build_xwayland directory (and kept the downloads and sstate path in the site.conf). i added this flags to the

BB_NO_NETWORK = "1"
BB_FETCH_PREMIRRORONLY = "1"

i removed the internet cable to simulate my offline computer. when running the bitbake fsl-image-qt6 it fails in the parsing

to fix it i need to connect to the internet and then run bitbake fsl-image-qt6 --runall=fetch and then offline build works. the problem that in the offline machine i will not be able to do the runall=fetch.

might you know what my error is and why i am not able to build offline

thanks

thanks for the response

i am sending the manifests from the repo and the error i get. i tried downloading the download twice and i still get the same error when running in offline (BB_NO_NETWORK = "1" and BB+GENERATE_MIRROR_TARBALLS = "1" )

this is the manifests from the repo

Hello,

You need to erase everything and restart to download yocto, since I can not reproduce the issue in my building. If you are working with none BSP from NXP, please contact your vendor for this issue.

Regards

hello

after a number of deletions and build i have found a workaround for the problem. it seems that the branch and has for the matter did not match between the downloads/github..matter.git to the bb file. i added to my site.conf

SRCBRANCH:pn-matter = "release/v1.4.

SRCREV:pn-matter = "9042e9281bf619ce0d06d043d5ac3c0c34c24bbe"

and that solved the parsing error. after that i have a fetch error that tried to get the thirdparty/nxp_matter_support that i did not find in my downloads (which successfully build an image with internet). so to workaround this problem i removed all the installs for "packagegroup-nxp-matter" and such.

This did not solve the problem but enabled me to build my image and because i do not need the application that use the matter it is a sufficient workaround

thanks

Hello,

If you download the complete bsp and build the full-image you should not have any issue, please tell us which BSP are you using to test.

Regards

greeran · ‎08-31-2025

i am deleted all the build and download and sstate. i am now building from scratch and hopefully tomorrow i will be able to test it with a clean build on a machine without internet
