On dev boards, this is 136 typically entered by holding down a "force recovery" button and 137 resetting the CPU. However, not all boards have such a button (one 138 example is the Compulab Trimslice), so a method to enter RCM from 139 software is useful. 140 141 Even on boards other than Trimslice, controlling this over a UART 142 may be useful, e.g. to allow simple remote control without the need 143 for mechanical button actuators, or hooking up relays/... to the 144 button. 145 146endif 147
