    @Chase-Riley The standard px4 Debian package will set up the data correctly such that the actuators tab will be visible. For SDK 1.0 the packages are all available at http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.0/binary-arm64/. To grab the px4 package use wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.0/binary-arm64/voxl-px4_1.14.0-2.0.34_arm64.deb

    @Eric-Katzfey Unfortunately once I switch back to the standard Debian package the Spektrum error is back. I had it working every power up with the Debian Package from Ben.

      @Eric-Katzfey the test deb file was just voxl-dev branch with the one line change to accept (0x02|0x01) protocol bytes with the error output shortened below 80 characters + debug print bools and macros in DSM parsing forced on. I can fly that one line change on a Sentinel to look for any unexpected consequences. It'd be great to coordinate on how to get such a change merged into the dev branch and a non-debug deb to Chase.

        @ben-grocholsky That would be great! Just submit a PR and I can merge it in and then cut a new release.

                @Chase-Riley I made version 1.14.0-2.0.54 with the Spektrum RC changes in it. You can get it with wget http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.54-202310161035_arm64.deb. Can you try it out and see if it fixes your issue?

                  @Eric-Katzfey Spektrum now works with that deb file, however I am not able to get the actuators tab in QGC just like @ben-grocholsky's deb file.

                    @Chase-Riley Okay, glad that Spektrum is now working. Can you create a new post for the actuator tab issue. That is something completely different than the Spektrum RC issue. Thanks!

                      @Eric-Katzfey I can make a new post if that is what you want me to do, however the issue that no actuator tab showing up has to do with the Debian Package Files that you and Ben have provided.

                      Ben's: https://drive.google.com/file/d/1XJBdAKxR0C0tYPDgfOB1uUGCJ6Pv_3kV/view?usp=sharing

                      Eric's: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.54-202310161035_arm64.deb

                      If I flash the standard Debian Package File (http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.0/binary-arm64/voxl-px4_1.14.0-2.0.34_arm64.deb) the actuators tab appears as normal. The only time the actuators tab does not appear for me is when I am running a custom Debian Package supplied by you or Ben. Both the your's and Ben's Debian Package files solve the Spektrum issue but they both break the ESC functionality. Please reference the post below where you told me that the standard Debian Package file sets up the data correctly for the actuators tab.

                      @Eric-Katzfey said in Voxl2 Spektrum Receiver error:

                        @Chase-Riley Ah, sorry, didn't realize the correlation there. The one I prepared is an updated one from the SDK version that worked so it should be setting everything up correctly. But apparently something is wrong. We'll test and see if we can figure it out.

                            @Chase-Riley I started from scratch and flashed SDK 1.0.0 and could see the actuators tab on QGC 4.2.4. I then upgraded voxl-px4 to voxl-px4_1.14.0-2.0.54-202310161035_arm64.deb. I still see the actuators tab. Since Ben's Debian was based on an older px4 that didn't yet properly support the actuators tab it's possible that something got corrupted in that change.

                                @Eric-Katzfey Would you suggest flashing my Voxl to SDK .0.9.5 and then back to 1.0.0 and start from there?

                                  @Chase-Riley No, but I would recommend deleting /data/px4/param/parameters before doing the SDK 1.0.0 flash.

                                    @Eric-Katzfey So delete that file and then flash SDK 1.0.0. Once SDK 1.0.0 flash is complete then upgrade to voxl-px4_1.14.0-2.0.54-202310161035_arm64.deb?

                                        @Eric-Katzfey I was able to delete the parameters file, flash SDK 1.0.0, and then upgrade to voxl-px4_1.14.0-2.0.54-202310161035_arm64.deb. I still am having the same issue. Spektrum works well however no actuators tab for the ESC. I did a quick test by downgrading back to voxl-px4_1.14.0-2.0.34_arm64.deb and the actuators tab appeared right away, however no Spektrum.

                                        To sum it up I am still having the same problem.
