The fault handlers blink different LEDs depending on the kind of fault: HardFault -> All MemManage -> Left of display BusFault -> Right of display UsageFault -> Left and right of display Additionally, they dump information about the fault to the flash and Serial (if connected). The information dumped to the flash can later be retrieved via Serial by sending a 'd'.
