I use version 4.1.21 with Am3352 self-designed board.
Use the ADC module as touchscreen mode, I found that the Sample Delay will affect event acquisition. How to calculate the Sample Delay? I have asked a similar question at here

Hello,

I cannot support software questions from Linux 4.1.21. I can support you if you are using a recent TI SDK. ("recent" means released within the last year). In particular, the AM335x ADC touchscreen driver has changed a lot over the last several years.

Regards,
Nick
