Verdin iMX8M Plus - Yocto build fails fetching uninative: 404 from Toradex Artifactory, server refused shutdown

Technical Support
1

Hi Team,

I’m working on building a Yocto image for the Verdin iMX8M Plus using the Toradex BSP 7.3.0+build.8 (scarthgap).

Setup Details:

Host Environment:

  • OS: Ubuntu 22.04.5 LTS (WSL2 on Windows 11)
  • Kernel: Linux 5.15.167.4-microsoft-standard-WSL2
  • Yocto packages: Installed as per Yocto 5.x system requirements

Target Board:

  • Target Board: Verdin-iMX8M Plus
  • BSP Version: scarthgap-7.x.y
  • Manifest: tdxref/default.xml

Initial Setup Command:

$ repo init -u git://git.toradex.com/toradex-manifest.git -b scarthgap-7.x.y -m tdxref/default.xml
$ repo sync
$ . export

Edited conf/local.conf:

MACHINE ?= “verdin-imx8mp”
DISTRO ?= “tdx-xwayland”

// NXP®/Freescale EULA
ACCEPT_FSL_EULA = “1”

Build Target: bitbake -k tdx-reference-multimedia-image

Problem: uninative Fetch Fails Mid-Build

The build proceeds to around 45–50%, then fails with 404 errors while fetching uninative components and then it fails with this error:

I have attached the full bitbake error log in the topic,

Questions:

  • Why is uninative failing to fetch from the Toradex Artifactory?
  • Is the URL deprecated or temporarily down?
  • Is there a way to override or mirror the uninative source?

Summary

  • Targeting Verdin iMX8M Plus with scarthgap-7.x.y BSP and tdx-reference-multimedia-image build.
  • Build consistently fails while fetching uninative due to 404 error from Toradex Artifactory.
  • Running build inside WSL2 (Ubuntu 22.04 on Windows 11).
  • conf/local.conf correctly set with machine, distro, and EULA acceptance.
  • Need guidance on:
    • Whether this is a known issue or temporary server problem.
    • How to manually override/unset uninative, if it’s optional.
    • If a mirror or alternate source can be configured.

Hi, I’m the Toradex AI Assistant.

I might make mistakes. Our support team will step in if needed. If I answered your question, please tick the “Solution” checkbox. For follow-up questions to me, please use @ToradexAI in your post.

Did you like my answer? :+1: :-1:

Hello! Thank you for the detailed information and clear questions regarding your build issue with uninative on the Verdin iMX8M Plus.

Let me address your points one by one:

1. Why is uninative failing to fetch from the Toradex Artifactory?

From the log, the 404 errors indicate that the requested uninative files are not available at the specified Toradex Artifactory URLs. This can happen if:

  • The files were not uploaded for this specific BSP release.
  • There was a change in the way uninative is managed for this BSP.
  • The URLs are deprecated or temporarily unavailable.

However, your build attempts to fall back to the standard Yocto Project downloads server and appears to download the required files successfully afterward:

http://downloads.yoctoproject.org/releases/uninative/4.7/x86_64-nativesdk-libc-4.7.tar.xz … 200 OK

So, the fallback mechanism is working as intended and should allow the build to continue.

Reference:
Build a Reference Image with Yocto Project/OpenEmbedded

2. Is the URL deprecated or temporarily down?

Given the persistent 404 response, it’s likely the specific artifacts for uninative are either:

  • Not provided in the Toradex Artifactory for this BSP (this is expected for some meta layers).
  • Or this is a temporary situation, but the fallback to Yocto’s official server is standard and safe.

This situation is not uncommon and typically does not indicate a hard failure as long as the fallback works.

3. Is there a way to override or mirror the uninative source?

Yes, you can manually override or add mirrors for uninative downloads.

Option 1: Allow the Yocto Mirror to Be Used (Default)

As in your log, Yocto will already try its own mirror after Toradex. If the download succeeds and you don’t want to see errors, you can suppress them, but this is generally not necessary.

Option 2: Override UNINATIVE_URL in local.conf

You can explicitly point UNINATIVE_MIRROR to Yocto’s site or another known good source. Add to conf/local.conf:

# Use Yocto's official download server as the first uninative mirror
UNINATIVE_MIRROR ?= "http://downloads.yoctoproject.org/releases/uninative/${UNINATIVE_VERSION}/"

Option 3: Provide Your Own Mirror

If you have a local mirror or want to use a different server, you can also set:

UNINATIVE_URL = "file:///path/to/uninative/${UNINATIVE_VERSION}/"

Where you host the necessary uninative tarballs.

4. Can Uninative Be Disabled?

Uninative is used to provide reproducible native builds across different build hosts. Disabling it is not recommended unless you are confident in your build environment and don’t need cross-host reproduction. If you want to proceed, set in conf/local.conf:

INHERIT_remove = "uninative"

However, this may break parts of the build or require additional native dependencies on your host.

Summary & Recommendations

  • The failed fetch from Toradex Artifactory is not uncommon and will not break your build if the Yocto fallback download works.
  • If you want to avoid the error or ensure reliability, set UNINATIVE_MIRROR in conf/local.conf as above.
  • Disabling uninative is possible but not recommended for reproducibility.
  • As long as your build fetches from a suitable fallback and continues, this is not typically a critical issue.

For more details, please see:
Build a Reference Image with Yocto Project/OpenEmbedded

If you encounter further build errors after the fallback fetch, please share those specifics.

Best regards, Toradex AI Assistant.

Hey, @Hariprabhu_13,

You are seeing the error coming from our URL because we append our artifactory to the premirrors here.

The unative actually comes from openembedded core, see this line from openembedded-core/meta/classes-global/uninative.bbclass:

UNINATIVE_TARBALL ?= "${BUILD_ARCH}-nativesdk-libc-${UNINATIVE_VERSION}.tar.xz"

From the logs you provided, it seems that the fetch actually succeeded after trying from the yocto project releases:

Did the build process actually fail? I believe it should continue as normal after fetching the file. If it did fail, the problem should be somewhere else, there were no other error messages?

Best regards,
