On dev boards, this is 142 typically entered by holding down a "force recovery" button and 143 resetting the CPU. However, not all boards have such a button (one 144 example is the Compulab Trimslice), so a method to enter RCM from 145 software is useful. 146 147 Even on boards other than Trimslice, controlling this over a UART 148 may be useful, e.g. to allow simple remote control without the need 149 for mechanical button actuators, or hooking up relays/... to the 150 button. 151 152endif 153
