Yocto build for imx8mp-ddr4-evk

[BillStrahm]

trying to do the imx-image-full 

It is erroring out in the download of nnshark do_fetch.

I have seen a suggestion to add do_configure[network] = "1" to the .bb file - I have done this and not seen a change.

Is there a known good repository to start from, are there known patches to apply to get through this?

Should I simply go down the docker path instead?

[lidongxu]

hello，
I have the same problem as you. Have you solved it？
Thank you very much！

[BillStrahm]

So the repo was initialized with: 

repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-langdale -m imx-6.1.1-1.0.0.xml

followed by:

MACHINE=imx8mp-lpddr4-evk DISTRO=fslc-imx-xwayland source ./setup-environment -b build 

Lets start why nnshark doesn't fetch in this environment.  If a bitbake recipie has to change, that is the bug, but the change I tried to make did not work so it is irrelevant.

To add a package to your custom image you have to add the next line in the local.conf file located in the folder build/config/

CORE_IMAGE_EXTRA_INSTALL += "nnshark"

and then compile with the command "bitbake imx-image-full"

[BillStrahm]

nnshark is already in the imx-image-full image.

I have gotten around this by going into the bitbake recipie for nnshark 

sources/meta-imx/meta-ml/recipes-nnstreamer/nnshark

and changing:

NNSHARK_SRC ?= "gitsm://github.com/nxp-imx/nnshark.git;protocol=https"

to simply git://

Do you know why the gitsm fetch is failing?

Hi @BillStrahm!

Sorry for the late response!

Could you please send me the log generated to review, please?

I have compiled the full image and I can't get the fetch error and I don't modify anything.

[BillStrahm]

can I get your nnshark do_fetch log. I am interested to see where it is getting the tarball that is failing from

[Chavira]

Hi @BillStrahm !

I attached my log.

Talking with my internal team, some time ago we had the same problem and the root cause is a proxy failure due to the firewall.

I have a workaround for the nnshark failure

There are 2 issues:   

1) nnshark repo has a submodule which is tried to be fetched/clone using the git protocol

 2) This submodule is cloned during do_configure stage, however, the global env variable http_proxy is not visible at this level

   Workarounds:

    1) Include a patch that changes the submodule url to an https repository (gihub)

    2) Explicitly set the http_proxy enviroment variable within the do_configure function at recipe

[BillStrahm]

So - from the bottom section of the log a bunch of fetch mirror failures for

curl https://mirrors.kernel.org/yocto-sources/git2_github.com.nxp-imx.nnshark.git.tar.gz

does return a nginx 404 error.  Did this tarball get renamed/moved?

[BillStrahm]

just did a bitbake -c fetch nnshark

It takes almost 20 minutes to fail sadly

Hi @BillStrahm !

I open a new folder and again I don get the error on fetch (see the attached log).
If you have that fetch error please try to update your packages on your Linux host machine.

Please try to install all the packages required to compile on Yocto with the next command.

sudo apt-get update

sudo apt-get upgrade

sudo apt install gawk wget git git-core diffstat unzip texinfo gcc gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm python3-subunit mesa-common-dev zstd liblz4-tool rsync curl zstd lz4 gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

[BillStrahm]

Have to fix up your list git-core is a dupe (I think) of git

pylint3 becomes pylint

python has no installation candidate

what is left was all up to date (errors on the cross compiler installed by yocto build I assume)

Hi @BillStrahm !

Thank you for contacting NXP Support!

What version of the kernel are you using?

could you tell me what in what file are you doing the modification?
