Build errors with Simulink CAN Transmit block on Raspberry Pi with CAN_MESSAGE as input

Hello,

I have a problem with the CAN-Transmit block from the Raspberry Pi Simulink hardware support package. If I put a CAN Pack block in front of the Transmit block and set the input datatype to CAN_MSG for the Transmit block, I get the following error message during the build process:

The data type of input port 1 is 'CAN_MESSAGE'. MATLAB System block 'CAN Transmit' only supports built-in, binary point scaling [Slope=1.0, Bias=0.0], Simulink enumeration, and bus data types.

Tested with Simulink 2021b and 2022a.

Does anyone have the same problem or a solution for me?

Try enabling "Output as bus" in CAN Pack block and then rebuild the model

This worked for me, thanks!
