The program that I'm testing this from is written in qt, the main GUI loop is still running, even though the touch screen has locked up, so the calls to the IIO lib are still being made, although I don't know if I'm getting back the same data as the last time it worked, or I'm not getting back any data at all. > > I tested it with the sampling set to twice a second, and the touch screen locked up more quickly than when set to only sample once a second. > Odd. Try increasing the charge-delay and see if you can find a value where it stops happening. Something tells me that it won't fix the issue. Where is the source tree for this kernel? Which dtb are you using? > Regards, > Greg >
