 Watchdog disable
 ----------------
 
-wdog-disable.bin is a location-independent watchdog disable function with a breakpoint instruction at the end. Useful for disabling the watchdog directly from OpenOCD.
+wdog-disable.bin is a location-independent watchdog disable function with a
+breakpoint instruction at the end. Useful for disabling the watchdog directly
+from OpenOCD.
 
 Usage:
 
     openocd -c 'reset halt' \
       -c 'load_image wdog-disable.bin 0x20000000 bin' \
       -c 'resume 0x20000000' # watchdog is disabled and core halted
+
+The file is saved generated in the repository to remove the need to have a
+compiler when flashing. It is only 34 bytes binary.
