Perhaps there is coupling between the LCD lines and the ADC lines?
On Beaglebone Black with BB-View 4.3" Cape from Farnell, the LCD lines and TSCADC lines are placed close to one another, hence the analog signals are affected by digital LCD signals, leading to above issue. This was reported when I submitted the patches in question. Please see http://thread.gmane.org/gmane.linux.kernel.iio/14710/focus=121321 http://thread.gmane.org/gmane.linux.kernel.iio/14710/focus=15242 I did document this in my cover letter. Please see http://thread.gmane.org/gmane.linux.kernel.iio/15583 I think its the same issue that you are facing. Regards Vignesh
