On dev boards, this is 139 typically entered by holding down a "force recovery" button and 140 resetting the CPU. However, not all boards have such a button (one 141 example is the Compulab Trimslice), so a method to enter RCM from 142 software is useful. 143 144 Even on boards other than Trimslice, controlling this over a UART 145 may be useful, e.g. to allow simple remote control without the need 146 for mechanical button actuators, or hooking up relays/... to the 147 button. 148 149endif 150
