I just completed a uBITX build using the JackAl modification and am having difficulty getting the touch screen to properly register touches. Running V096.7 from the JackAl groups.io site along with the R8875 file also published there compiled with Arduino 1.8.12 running on a windows 10 machine. Seems like the calibration files are not being stored for some reason. Earlier teensy s/w versions are alleged to work (I tried downgrading to 1.52 beta 5 without success). Any ideas on root cause appreciated....
