We have found the iperf3 not work properly, and found the original iperf3_git.bb is version 3.1. Then, we found new 3.6 is on gitHub. Do you know how to upgrade yocto to use newer version of iperf3 ?

Thanks.

Hello Steven Yu,

The L4.9.88_2.0.0 BSP supports the iperf 3.2 version. The master of the Open Ebedded Yocto layer does have the 3.6 version:

https://layers.openembedded.org/layerindex/branch/master/layer/meta-oe/

However, you would need to add it manually and fix all dependencies required by it, which can be tricky. Alternatively, you could write a recipe that installs it from the source code.

 For more information about customizing Yocto please check the Yocto Project Reference Manual (link below)

https://www.yoctoproject.org/docs/2.4/ref-manual/ref-manual.html

I hope this helps!

Regards,

Hi gusarambula,

Follow the first link, I can see this recipe. 

https://layers.openembedded.org/layerindex/recipe/32243/

I have seen one recipe file and two patch files, do you know any good method to download it ?

Currently, I do it by select all on web browser, copy and paste to my local PC editor, but I feel this is strange method. If there are many files, it is easy to make wrong. 

Any method to update the sub-tree in my codebase ?

Regards,

Steven Yu
