We would like to rebuild/reconfigure a custom kernel for the wp85 using instructions from this link:
[legato.io/legato-docs/latest/yoc … ctoImages3](http://legato.io/legato-docs/latest/yocto_legato.html#getstartedYoctoLinux_rebuildYoctoImages3)
There does not appear to be a stdbuild.sh file
If attempting to run the standard example from README.build:
./build.sh -p …/poky/ -o …/meta-openembedded/ -l …/meta-swi -m swi-mdm9x15 -q -t -4 j 4 -d
gets this error:

Summary: There was 1 WARNING message shown.

Is the swi-mdm9x15 argument correct for wp85 or is it possible the Legato-Dist-Source-mdm9x15-SWI9x15Y\_07.08.03.00.tar.bz2 (from the Legato Downloads link) is not the latest?
If attempting to simply run ‘make’ (via these instructions [legato.io/legato-docs/latest/yocto\_build.html](http://legato.io/legato-docs/latest/yocto_build.html)) from the yocto build generates the following errors:
Failed to fetch URL git://codeaurora.org/platform/hardware/ … LNX.LE.2.1
…
Fatal : unable to connect to [codeaurora.org](http://codeaurora.org):
Any help would be appreciated.

Is there anyone else that was successful to build the kernel for wp85 ?

Hi tlapsley,
Have you tried to run:
```auto
make image
```
Before building kernel? You need to run this command only once. After that you can:
```auto
cd poky
source ./oe-init-build-env
cd ../../build_bin
bitbake -c cleanall linux-yocto (to clean)
bitbake linux-yocto (to build it again)
bitbake -c compile linux-yocto -f (to force kernel compilation)
etc.
```
You can read more about bitbake commands at [url][Welcome to the Yocto Project Documentation — The Yocto Project ® 4.0.999 documentation](https://www.yoctoproject.org/documentation/bitbake-user-manual-0%5B/url%5D) .
Please, let me know if you have any other questions.
Best regards,
Dragan

I have the same problem, but `make image` didn’t help:

I have Legato Linux distribution Version 16.07.0 downloaded from [source.sierrawireless.com/resour … linuxdist/](http://source.sierrawireless.com/resources/legato/legatolinuxdist/) and I am trying to build on ubuntu 16.04.
Any help will be appreciated.

Where you able to get past this? I’m having the same issue.

I built it at home : ) I have very restricted connection at work, some TCP ports were blocked, the problem was in these restrictions.
