      Hi,

      I'm interested in activating the CAN bus to retrieve range sensor data from the J8 connector using the UAVCAN protocol. However, enabling the feature results in an error. Could you please provide guidance on how to enable the UAVCAN feature for the J8 CAN bus? Thank you.

      #default.px4board
      CONFIG_DRIVERS_UAVCAN=y
      CONFIG_BOARD_UAVCAN_INTERFACES=1
      #nuttx-config/nsh/defconfig
      CONFIG_CAN=y

      boards/modalai/fc-v2/src/can.c:52:10: fatal error: stm32_can.h: No such file or directory
