      Hello,

      I'm building out voxl-mpa-tools from source. I'm interested in voxl-inspect-gps. The app that is installed on the device's stock build runs/outputs as expected, but the one that I am building from source (without any modifications) gets hung with the following output: waiting for Autopilot /run/mpa/mavlink_gps_raw_int/. There are no errors/warning from CMake, and I am following the READMEs verbatim.

      I assumed after cloning voxl-mpa-tools and voxl-docker that I would be able to just run the build and deploy the working app(s). Any hints as to why this might not be working as anticipated?

      • Device version of voxl-suite: 0.9.5
      • I've tried the latest dev branch of voxl-mpa-tools (v1.0.1) and v0.9.5.
      • I've tried using voxl-cross V2.5 and V2.4 to build.
      • Host = Ubuntu 18.04.6 LTS
      • Device = Qualcomm Flight RB5

      I haven't troubleshot much farther than pipe_client_open (247, voxl-inspect-gps.c).
      Just wanted to sanity check here first before going down a rabbit hole.

      Thanks!

        @Jeremy-McCabe SDK 0.9.5 uses a much older version of voxl-mpa-tools, v0.7.6.

        Packages are often very dependent on the versions of other packages or system image, therefore you can't really just build off of dev without all over the other packages being from dev as well.

        So, if you were just looking to do small tweaks based off of the voxl-mpa-tools that is part of SDK 0.9.5, you'd likely have to start with the v0.7.6 tag: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/tree/v0.7.6?ref_type=tags

          Awesome! Thanks Tom, that worked. Just for my awareness, how did you know which SDK maps to which specific tag (SDK 0.9.5 -> v0.7.6 tag)?

            @Jeremy-McCabe There are a couple of ways to determine that, one way is to check the sdk-0.9 tag on the repo and see what the corresponding version is in the package's control file: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/sdk-0.9/pkg/control/control

            The other is to look directly at our package repo server: http://voxl-packages.modalai.com/

            and check the list of packages that are in that sdk (if there are multiple of the same, it'll use the newest): http://voxl-packages.modalai.com/dists/qrb5165/sdk-0.9/binary-arm64/
