|
|
+ Tegra's boot ROM supports a mode whereby code may be downloaded and
|
|
|
+ flash-programmed over a USB connection. On dev boards, this is
|
|
|
+ typically entered by holding down a "force recovery" button and
|
|
|
+ resetting the CPU. However, not all boards have such a button (one
|
|
|
+ example is the Compulab Trimslice), so a method to enter RCM from
|
|
|
+ software is useful.
|
|
|
+
|
|
|
+ Even on boards other than Trimslice, controlling this over a UART
|
|
|
+ may be useful, e.g. to allow simple remote control without the need
|
|
|
+ for mechanical button actuators, or hooking up relays/... to the
|
|
|
+ button.
