We would like to rebuild/reconfigure a custom kernel for the wp85 using instructions from this link:

[http://legato.io/legato-docs/latest/yocto\_legato.html#getstartedYoctoLinux\_rebuildYoctoImages](http://legato.io/legato-docs/latest/yocto_legato.html#getstartedYoctoLinux_rebuildYoctoImages)  
There does not appear to be a [stdbuild.sh](http://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:

Loaded 782 entries from dependency cache.

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

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 [http://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/libhardware;branch=LNX.LE.2.1  
…  
Fatal : unable to connect to [codeaurora.org](http://codeaurora.org):

Any help would be appreciated.

Hi,  
Would be better to ask this particular question on the legato forum:

cheers,
