As the TMC4361A-EVAL board uses the SPI interface to communicate with the Landungsbrücke interface board, you cannot combine it with a second motion controller in an evaluation kit setup. This is because the SPI interface only allows for communication with one motion controller board in the setup. For quick testing and setup, it is recommended to combine the TMC4361A with one of the driver evaluation boards like the TMC23x, TMC24x, TMC26x, or TMC21x0 evaluation boards.
