@Eric-Katzfey We got around it by forcing UART mode and connecting through an FTDI converter. Thanks anyway!

Hi,
Is there a supported method to access i2c devices from the DSP on the flight computer rather than the px4 side of things? I'm trying to initialize a ROS2 driver for the BMO055 9-axis IMU and having trouble communicating. Sensor is wired to spare i2c on J19, VOXL2. If it's accessible to PX4, it must be exposed somewhere in ubuntu, right?

nevermind, this is fixable with voxl-configure-mpa-to-ros2 and voxl-configure-pkg-manager. Leaving this up for anyone else having the same problem.

Hi,
I'm having issues installing ros2 and running voxl_mpa_to_ros2 on VOXL2. I'm running a fresh flash of SDK1.1.2 on VOXL2 and installing via

apt install voxl-ros2-foxy 
apt install voxl-mpa-to-ros2
apt install voxl-microdds-agent

sourcing ROS2 & running voxl-configure-microdds to enable the systemctl service. after reboot, command

ros2 run voxl_mpa_to_ros2 voxl_mpa_to_ros2_node

yields

/opt/ros/foxy/mpa_to_ros2/install/voxl_mpa_to_ros2/lib/voxl_mpa_to_ros2/voxl_mpa_to_ros2_node: error while loading shared libraries: libtinyxml2.so.6: cannot open shared object file: No such file or directory

checking ROS topics, as

ros2 topic

yields

Any suggestions for running voxl-mpa-to-ros2? is there a python dependency script that the installation needs above the apt install?
Thanks
