for controller, i have that (without sdcard):
ERROR - sd card initialization failed!
ERStarting Robo-Tank v5.11
Initializing sd card...
ERROR - sd card initialization failed!
ERROR - Can't find index.html file!
This should read 50: 50
Starting Controller -------------------
Controller seems to be frozen.
There is only one red brick on screen even if I restart
