Yocto Build for IMX8 EVK

I want to build a full image and then SDK for the IMX8 QUAD EVK so I can build gstreamer plugins.

 

I have tried these repo init/sync combos:

            imx-linux-honister imx-5.15.5-1.0.0 

            imx-linux-hardknott imx-5.10.72-2.2.0 

            imx-linux-hardknott imx-5.10.35-2.0.0 

            imx-linux-zeus imx-5.4.24-2.1.0

            imx-linux-rocko  imx-4.9.88-2.0.0

           

$ MACHINE=imx8mqevk DISTRO=fsl-imx-xwayland source imx-setup-release.sh -b bld-imx8mqevk-xwayland

$ bitbake imx-image-full

 

Unfortunately none of these run to completion.  They all seem to have broken links.

 

Can you recommend a newer build that is still complete?

 

Thanks

Hi @genekinaraai , I am facing the same issue as yours, have you got any breakthrough, please share your observation.

Thanks in advance.

Hi,

I wish I had the ultimate answer to share.  Perhaps my observations might trigger an idea that helps.  My main observation is that yocto builds seem to work better with higher performance systems.  Packets are transferred over TCP/IP, so each packet is retried until successful.  That should lead to every yocto build being identical, just slower on some machines, but my experience shows a difference. 

Instead, as I build on larger machines, my builds apparently produced fewer errors.  The last two builds came close.  I used an i9 with 32GB memory and had a handful of errors.  My last build was on a Xeon with 128GB memory and seems to have only one error:

---- ERROR: Task (/home/kuser/yocto/sources/meta-imx/meta-ml/recipes-libraries/onnxruntime/onnxruntime_1.10.0.bb:do_install) failed with exit code '1'

NOTE: Tasks Summary: Attempted 9597 tasks of which 0 didn't need to be rerun and 1 failed.

Summary: 1 task failed:

  /home/kuser/yocto/sources/meta-imx/meta-ml/recipes-libraries/onnxruntime/onnxruntime_1.10.0.bb:do_install

Summary: There were 4 WARNING messages shown.

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

I wonder if yocto recipes can build the same exact image, or do the recipes change over time without the version numbering change?  If the recipe is just a suggestion and not a law, then I could see it behaving differently for various builders.

pls refer to the yocto user guide which has detailed linux host machine request:

To get the Yocto Project expected behavior in a Linux Host Machine, the packages and utilities described below must be installed.
An important consideration is the hard disk space required in the host machine. For example, when building on a machine running Ubuntu, the minimum hard disk space required is about 50 GB. It is recommended that at least 120 GB is provided, which is enough to compile all backends together. For building machine learning components, at least 250 GB is recommended.
The recommended minimum Ubuntu version is 18.04 or later. The Chromium version 74 ir later requires Ubuntu 18.04. The latest release supports Chromium v91, which requires an increase to the ulimit (number of open files) to 4098.

I ran the honister build again from scratch.  The full error log.do_package.2555 is attached.  I don't mind installing a fresh copy of Ubuntu 20.04 if that will help begin the build with a known good state.  Is that a good next step?

cannot see . seems no head no Tail.

 

we want to see the screen , such as you type "bitbake xxx" then after that all the screen showed in order .

thank u

I created a Ubuntu 20.04 docker to guarantee the build system is clean.

The build did not complete.  I found this in the middle of the console-latest log:

ERROR: qtbase-6.2.2-r0 do_install_ptest_base: ExecutionError('/home/kuser/yocto/bld-imx8mqevk-xwayland/tmp/work/cortexa53-crypto-mx8m-poky-linux/qtbase/6.2.2-r0/temp/run.do_install_ptest_base.13696', 1, None, None)
NOTE: recipe xprop-1_1.2.5-r0: task do_install: Started

How to fix this?

That is the only "ERROR:" I find in the console-latest log.  Does that mean this is the last error?

I too am getting a build error during the qtbase do_install_ptest_base task, on Ubuntu 20.04 with a clean build environment using the latest imx manifest in the IMX Yocto Project User's Guide (-b imx-linux-honister -m imx-5.15.5-1.0.0.xml). 

If I force the build to continue using "bitbake imx-image-full --continute", it still fails at this step the first time. But then if I run that command again, the qtbase do_install_ptest_base task succeeds. I did get other build errors later in the process that I haven't debugged yet. But it seems like qtbase do_install_ptest_base might be missing a dependency in it's recipe.

Hi Gkelly1,

I am sorry to hear you are also having trouble with your yocto build.  I just noticed there is a new guide published today:

https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

 

I suspect the recipes change, or the repositories change or go missing, so this newly published guide must have just been tested.  Hopefully it will work!

 

It might be helpful to build the smallest image first.  I need gstreamer, so I am building the full version.  The smallest image won't be useful for me.

 

There are also options to build from a local cache of files instead of pulling them all down during build time.  I haven't figured it out yet, but that should insure that flaky repositories are not an issue.

My latest error has something to do with onyx.  Google searches show things I can try, but first I will try the newly released recipes.

 

Good luck, and please post your success or failures so others can build on that.

I tried the new repo manifest in the updated NXP document (-b imx-linux-kirkstone -m imx-5.15.32-2.0.0.xml) and still ran into the same issue - that qtbase_git.bb:do_install_ptest_base fails on the first build of imx-image-full if the build cache is clean. But it does complete on the 2nd build attempt if I had used "--continue" during the first attempt. And, strangely enough, if I start with "bitbake qtbase" (with an empty build cache), that also succeeds. So I suppose it's a suitable workaround to run "bitbake qtbase; bitbake imx-image-full" for now.

all that release are tested and published then , so aall are no issues for sure , i can build all no any faults .

 

so it is your config or nework own issues

 

[please showed us your full build logs thenwe may be can advices u in details pls 

 

 

thank you

What config do you think is the issue? 

 

What kind of network is required? I am using two different cable modem connections with no VPN, one with 50mbps, and the other with 350mbps.  These failures occur on both networks.

I am following the steps from: "i.MX Yocto Project User's Guide Rev. LF5.15.5_1.0.0 — 31 March 2022"

There are many "do_fetch: Fetcher failure" errors.  Attached is one of the results.

My hunch is that broken links are related to the age of the recipe, so the newer builds ought to work with a higher probability.  I believe imx-linux-kirkstone is supposed to be released this month, but it appears I am too early grab that yet.

I am digging into the Yocto documentation to figure out how to build from a local directory instead of downloading the repos each time.  Perhaps this will eliminate the Fetcher failure.

I hope there is a faster way to fix this.  Any advice will be greatly appreciated.

do fetch errors related to your network, you can delete the packages by cleasstate "bitbake -c cleasstate libgphoto2" then bitbake again
