Hello guys,

```
     legato stoped in my mangoH Red board flashing new yocto image.

     I've downloaded "Legato-Dist-Source-mdm9x06-SWI9X06Y_02.13.02.00.tar.bz2" and builded yocto for wp77XX without any configurations.
   Legato is not starting by default,. Hence i started running legato manually and encountered below errors.

  _ **root@swi-mdm9x28:~# legato start** _

```

_ **Starting Legato…** _  
_ **./system/bin/startSystem: error while loading shared libraries: libssl.so.1.0.2: cannot open shared object file: No such file or directory** _

```
  Is there any thing, that i've to configure in default yocto for legato..?

```

Thanks & Regards,

Did you build/install Legato separately from yocto?

It looks like you’re not using the latest yocto release for your module. That can be found here: [https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release-components/](https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release-components/) and is SWI9X06Y\_02.18.05.00.

Hi dfrey,

```
  Thanks for you support.
  I din't build legato separately. It should be part of yacto right..?
  I've used "SWI9X06Y_02.13.02.00" Release 7.

```

Is there a reason why you don’t want to use release 9.1 which I linked to in my previous post?

Hi @mallikarjunareddy,

The legato team has recently started publishing a lot of their repositories through a public gerrit instance. This gerrit instance is available at [https://gerrit.legato.io](https://gerrit.legato.io). You need to have an AirVantage account to login.

Once you’re logged in, you need to go into the settings and upload an ssh key. You also need to choose a username in the settings.

Now you should be able to do:  
`git clone ssh://gerrit.legato.io:29418/meta-swi.git meta-swi`

The other relevant repository is `msm-3.18` which is the linux kernel repository for the wp76/77. Please see my recent commits to both of those repositories that relate to bluetooth. Specifically commit `ad1c0353657b945c0f6a1e5617b7011f1f8b628e` to the kernel resolves the error in your yocto log.
