Hello,
I don't use ADC on AM335x. I saw the following description.
Connect all TSC_ADC terminals (VDDA_ADC) to same ground as all VSS terminals.
Connect the respective VDDA1P8V_USB terminal to any 1.8-V power supply.

I don't understand the difference of terminal processing between VDDA_ADC and VDDA1P8V_USB. I guess connecting VDDA_ADC and 1.8-V power supply is better. Please give me advice.
Regards,
Kazu
