1. Download Legato Distribution Source Package from sierra wireless website:

Yocto Source (Around 4 GB)
The file name is Legato-Dist-Source-mdm9x15-SWI9X15Y_07.13.05.00.tar.bz2

2. Extract the downloaded Distribution source package:

Run command: tar -xvjf Legato-Dist-Source-mdm9x15-SWI9X15Y_07.13.05.00.tar.bz2

3. Disable Legato configuration to build Yocto

Run command: cd yocto
Run command: export LEGATO_BUILD=0

4. Build Yocto images from source

Run command: make image_bin
If you get the error not found 'serf.h', then follow the steps below, otherwise skip to the next step.
    Go to directory: cd meta-swi/common/recipes-devtools/
    create directory: mkdir subversion
    Put attach file: subversion_1.8.9.bbappend, under directory subversion
    The full path would be: yocto/meta-swi/common/recipes-devtools/subversion/subversion_1.8.9.bbappend
    build Yocto images again: make image_bin

5. Set environment under yocto directory, this will get command bitbake run:

Run Command: . ./poky/oe-init-build-env

6. Build Linux kernel with Buffer Frame driver modules support

Go to directory: yocto/build_bin (cd …/build_bin)
Configure kernel with default:
    Run command: bitbake linux-yocto -c kernel_configme -f
Configure kernel to add BT driver module in Linux configuration
    Run command: bitbake linux-yocto -c menuconfig

Exit and save Frame Buffer Linux config
Rebuild kernel image: bitbake -f linux-yocto

7. Rebuild rootfs filesystem and images

bitbake -c cleansstate mdm9x15-image-minimal
bitbake mdm9x15-image-minimal

Check new build CWE images: yocto_wp85.cwe

Go to images directory: cd build_bin/tmp/deploy/images/swi-mdm9x15

Reflash new image with Frame Buffer driver module support to the target board

on Windows: FDT command: fdt yocto_wp85.cwe 
on Linux: by command: fwupdate download yocto_wp85.cwe
