My Eval board CN-0376 does not work when power (3.3V) is fed through PMOD connector. The SDP board is taken away, the PWW_SEL jumper set to PMOD. The SDO stays low whatever I try. My SPI works OK because with a self fabricated ADC7124 board it works fine.

My Eval board CN-0376 does not work when power (3.3V) is fed through PMOD connector.

 

My set-up:

The SDP board is taken away, the PWW_SEL jumper set to PMOD. All connections to external controller are connected on the PMOD connector at the side of the ADC. The SDO stays low whatever I try.

 

My SPI works OK because with a self fabricated ADC7124 board it works fine.

The EVAL board works fine with the SDP board and the CN-0376 software.

 

What do I do wrong?
