I have connected my 4 adc connector pins(sclk,din,dout,cs_n) to gpio pins. where do need to map these pins in .tcl file so that it takes proper input from the adc?

Hi @ngoya5​

Could you provide more info:

1) What is the device

2) Can you share your schematic of the connection

3) What you mean by map these pin in .tcl file. What are you trying to do? and what is your expected results?

4) Generally, what is your intention and end goal?

DE10_NANO_ADC.sof would already be able to read the ADC. There are already steps provided in the doc to read the ADC.

Check out their user manual:
