@kgn-mdlai Unfortunately, the April Tag code is quite outdated and hasn't been tested on any of our latest hardware. As it is now it is provided as reference code and if you are able to get things working correctly on your own we are happy to accept PRs to the repo. We do plan an update of this in a future revision of the SDK but there is no scheduled date that we can provide right now.

@tejasram The source code is here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tag-detector. Perhaps try changing #define MAX_TAG_LOCATIONS 64 in locations.h.

@cbay That driver is not part of the build nor has it ever been tested on VOXL 2. You would have to add it to the build (e.g. in https://github.com/modalai/px4-firmware/blob/voxl-dev/boards/modalai/voxl2-slpi/default.px4board)

@taiwohazeez This is what most people use: https://qgroundcontrol.com/

@ggangmi What was the flight mode on takeoff and what did it unexpectedly change to? There should be logs in /data/px4/log. They may be incomplete or maybe even corrupted if the drone lost power in the crash but there should be something there. The logging starts when the drone is armed.

@Nitin-Varma-Vegesna If you re-install or update your SDK to the latest it will properly set all of the parameters.

@brandon You'll need to load SDK v1.6.x to get it.

@sja123 No, unfortunately, we do not currently support boot from SD card.

@magnetocircuit Yes, this is supported. In the config file for px4 /etc/modalai/voxl-px4.conf set ESC=VOXL2_IO_PWM_ESC.

@colombe-ai I'm not sure how much we're going to be able to help to get this going but I'd start with that magnetometer. Put an oscilloscope in the lines and see if you see any activity.

@colombe-ai How did you end up with this drone? Do you know the history of it? Has it been involved in some crashes? There could be some connector / cable damage that is causing some of the peripherals to no longer work. It's going to need some low level troubleshooting.

@colombe-ai Can you please provide the SKU? (See: https://docs.modalai.com/sku/#inspect-sku). Was this drone flying before you updated? What version were you using before? If you go back to that version does everything work normally again?

@bendraper I just tried it and it is working now:

@bendraper The code is open source. It is located here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/tree/dev?ref_type=heads. We encourage users to clone the repo and familiarize themselves with the code base. Did you try setting offboard_mode to off? Did it stop the SET_POSITION_TARGET_LOCAL_NED messages from being sent out?

@bendraper I would recommend using dev instead of master. dev is latest, master is an occasional snapshot of dev. However, dev can sometimes be broken so that's always a risk.

@bendraper You cannot always match dev and master. Since you want to build master I would suggest using staging for you dependencies instead. Why don't you want the dev branch?

@bendraper If you don't provide any arguments then the command will not work and you won't get any dependencies installed.

@bendraper Which repo are you using for the dependencies? For example: voxl-cross(4.4):~(master)(1.9.20)$ ./install_build_deps.sh qrb5165 staging

@jonathankampia https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-pipe/-/blob/master/library/src/interfaces.c?ref_type=heads#L72

@bendraper Edit /etc/modalai/voxl-vision-hub.conf and set "offboard_mode": "off"
