Hi,

You may see this pin placement error in the Quartus® II software if you have enabled the Passive Serial (PS)configuration scheme and assigned the DCLK pin as a regular I/O pin. You can only assign the DCLK pin as a regular I/O pin if you selected the Active Serial (AS) configuration scheme. When the Passive Serial configuration scheme is selected, the DCLK pin can only be used as a programming pin.

Resolution

Change to the Active Serial configuration scheme or remove the user signal location assignment to the DCLK pin.

please refer pin connection guideline.

regards,
Farabi

    Sorry, I failed to understand. How DCLK pin related to ADC pins? And where do I change this configuration to Active Serial?

    As I see in MAX10 Configuration Scheme may be only - Internal Configuration. It's an on board flash in the device.

      Well... I found the answer - If you use bank 1A for ADC, you cannot use the bank for GPIO.

      At least something stays rock solid - the support is traditionally lame on the forum.
