REFIN is tied to GND,
REF is tied to 5.0Vref,
VDD_5V is 5.4 VDC
I used default settings, also 4 lane SDOs, all four SDO always output zero. (all 0 on scope)
I did configure the 0x20 register for 4 lane and 32bit access, all zero
I skip configure registers and use the default setting, still all zero.
