Per the 'ARM MPS2 and MPS2+ FPGA Prototyping Boards Technical Reference Manual' (100112_0200_07_en): 2.1 Overview of the MPS2 and MPS2+ hardware The MPS2 and MPS2+ FPGA Prototyping Boards contain the following components and interfaces: * User switches and user LEDs: - Two green LEDs and two push buttons that connect to the FPGA. - Eight green LEDs and one 8-way dip switch that connect to the MCC. Add the 2 LEDs connected to the FPGA. This remplaces the 'mps2_fpgaio_leds' trace events by the generic 'led_set_intensity' event.
