On dev boards, this is 137 typically entered by holding down a "force recovery" button and 138 resetting the CPU. However, not all boards have such a button (one 139 example is the Compulab Trimslice), so a method to enter RCM from 140 software is useful. 141 142 Even on boards other than Trimslice, controlling this over a UART 143 may be useful, e.g. to allow simple remote control without the need 144 for mechanical button actuators, or hooking up relays/... to the 145 button. 146 147endif 148
