Hello! I am trying to run an example on the Olimex-stm32-e407 by following the micro-ROS application tutorial for RTOS and getting some errors while building.
i am doing on ubuntu 18
setup is Dashing Diademata and crystal also
when creating the framework with the following command
ros2 run micro_ros_setup create_firmware_ws.sh nuttx
the following error appears

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
micro_ros_agent: Cannot locate rosdep definition for [microxrcedds_agent]

i have installed the following package
ros-crystal-micro-xrce-dds-agent
ros-crystal-microxrcedds-agent-cmake-module
ros-crystal-microxrcedds-agent

and installed Micro-XRCE-DDS-Agent using https://micro-xrce-dds.docs.eprosima.com/en/latest/installation.html
but still i am getting the same error

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
micro_ros_agent: Cannot locate rosdep definition for [microxrcedds_agent]

is there any package i am missing? or any other steps to follow?
Thank you very much.
