Hello all,

I'm trying to build i.MX6 fsl-image-qt5 image and Yocto always fail during the fetch step.

Git repository seems to be unreachable.

The yocto output :

Is there any other git repository available?

Hello Kwiatkowski Frederic,

I’ve seen some people having problems with the git repositories lately buy always intermittently. Have you tried baking again?

I tested the 4.1.15 BSP and it seems it’s working fine right now. Please test it again. You may want to force fetch the source code first and then bake the image later to make sure the source code is downloaded before the building process.

$ bitbake <image_or_recipe> -c fetchall

I hope this helps!
Regards,

  Hi Gusarambula,
  
  I am also facing the same error. But I was just wondering if this could be coz of Proxy also. Kindly let me know if working behind proxy gateway also does affect fetching this link. If yes, what do I have to do to make it work. Kindly help!!

      Hello Gaurav Kumar,
      
      Working under a proxy does affect git and Yocto (as bitbake needs to fetch source code on real time).
      There is some documentation regarding this as part of the Yocto Project, perhaps it may be of help:
      Working Behind a Network Proxy - Yocto Project

        gusarambula Thank You for your quick response Gusarambula. But I am sorry to say that these all settings I have already done and still facing the same issue. Along with these settings, I made ~/.curlrc as well for proxy settings. Is there anything else I am required to do to make my bitbake fetch kernel and u-boot? Should I try changing their SRC_URI somewhere?? Kindly help!!

        I'm sorry to hear you're having problems with your proxy. Changing SRC_URI wouldn't help as chances are you are not being able to fetch from any servers. You would need to make sure that the protocols can reach the servers and it would vary from proxy to proxy. If you can contact your network administrator I would recommend you requested help with this.

        Thanks Gusarambula, I did it the something else, and for everyone facing the same problem, I am narrating:
        I read somewhere that when bitbake fetches these files, it places them into the "downloads" directory. So with my understanding, I directly cloned both linux-imx and u-boot using
        $ git clone <cloning-link>
        and did put it into the "downloads" directory. Once I did it, linux-imx as well as u-boot, both got compiled and errors vanished. gusarambula Kindly correct me if this was not the correct step I should have taken.

  Hello Frederic,
  
  Would you please share with me the commands you're using? I'd like to try to reproduce this error as the 4.1.15 BSP seems to be working correctly.
  
  I'm testing with:
  $ cd fsl-release-bsp
  $ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga
  $ repo sync

    Hi,
    
    the repo sync step worked when i've tried it but not the "bitbake fetchall fsl-image-qt5".
    
    I've tried several time "git clone git://git.freescale.com/imx/linux-imx.git" without any succes.
    The connection ends before the data transfer is finished.
    
    The solution i've found was to copy the linux-imx download i've done several weeks ago on my new computer even if i would have prefered to use a clean fetch from the Internet

        Finally I was able to clone it. Not sure if it was a problem with my local connection, or with the server.

        Hello Surendra Dhobale,
        
        What BSP are you using? Would you share the commands you’re using and on what documentation did you find them? I don’t recognize the inux-imx-4.1.15-ro tag.

Hi,
There are several causes for the index-pack error, from memory resources to network problems.
I found that specifically for the following error in a Ubuntu 16.04 system:
error: inflate: data stream error (invalid distance too far back)
fatal: pack has bad object at offset 28071701: inflate returned -3
fatal: index-pack failed
The error was caused when upgrading from 16.04.0 to 16.04.x. As part of that upgrade the Linux kernel is held back and is not updated (kept at 4.4 base). From then onwards, git clones of any Linux kernel repository which contains big packed objects failed with that error.
Forcing the kernel to update to the new hardware enablement kernel (4.10 based) fixed it for me:
sudo apt install –install-recommends linux-generic-hwe-16.04
