In my custom board I have a four wire resistive TS connected to the imx LRADC as in the EVK...

when I ran ts_calibrate it takes like 15 minuites to change the test points

does the ts caliberation has something to do with the panel selected, b/c it's fast when I'm using the default panel driver (LMS430),...all the problem show up after I edited the driver to my specific panel (320x240 3.5"....

Regards
