Hi, I am trying to add IPSec to the WP7702 on the magOH Red. To achieve this I downloaded the tarbal and Added the following to local.conf `DISTRO_FEATURES_append = " ipsec"` And created a custom recipe file similar to mdm9x28-image-minimal with the addition of IMAGE\_INSTALL\_append = " strongswan " I then successfully built the image I downloaded the modem firmware and legato firmware from the [source site](https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release-components/) I created a custom spk using: `swicwe -o custom-firmware.spk -c SWI9X06Y_02.22.12.00_00_SIERRA_001.021_000.spk yocto_wp77xx.4k.cwe legato-18.09.2.cwe` Flashed it using: `swiflash -m WP77XX -i custom-firmware.spk` I got: `Firmware Download SUCCESS` However it seems that the image on the device does not contain the updated firmware, I was wondering if I am doing something wrong along the way. Thanks, S ---

> I then successfully built the image > Can you elaborate on what you did to build the image? Are you sure that the firmware you built/installed is not running? Have you considered the possibility that `strongswan` wasn’t included in your build? Maybe you can search the build directories to see if it looks like it was built. ---

> Can you elaborate on what you did to build the image? - I ran `make dev` - Added `DISTRO_FEATURES_append = " ipsec"` to local.conf - made a renamed copy of /meta-swi/meta-swi-mdm9x28/recipes-core/mdm9x28-image-minimal.bb - made a renamed copy of /meta-swi-extras/meta-swi-mdm9x28/recipes/images/mdm9x28-image-minimal.bbappend - Added `IMAGE_INSTALL_append = " \ strongswan \ "` to the bbapend file - Then ran `bitbake ` > Are you sure that the firmware you built/installed is not running? Have you considered the possibility that strongswan wasn’t included in your build? i’m not sure how to check it, the tarbal in `/tmp/deploy/images` named `mdm9x28--swi-mdm9x28-wp.tar.bz2` contains `ipsec` in `/usr/sbin/` however it is not in the module’s file system. I’m not sure how to check if it is contained in `yocto_wp77xx.4k.cwe` ---

I have not, I haven’t really worked on this much
