Well, there's a message in the u-boot bin at least:
Code:
Got dual finger touched!!
waittouch
ntxup waittouch [interval (ms)] [timeout (ms)] - polling touch each interval and wait until touch pressed .
Can't get it to work myself, though. Maybe I'm doing something wrong after all.
Or it's a timing problem. If u-boot does the tap detection, it has to do it before it loads the kernel. But the device boots fast; I'd be surprised if it even waited 1 second for a tap.
