Hi @Ankush 

Yes PL MIG interface supports 32bit interface.

ZCU104 provides SODIMM, you can configure as per your requirement.

Hi Pratap,
On ZCU104 Eval board, The DDR related HP bank pins are connected to SODIMM Socket.
This SODIMM Socket is to insert 64bit DDR chip.
So even if we configure and do assignment for 32bit DDR inside the FPGA, Is it possible to connect the 32bit DDR memory on ZCU104 Board SODIMM socket? If yes what will be the pin assignment for 32bit DDR? (In ZCU104 pin assignment for 64bit DDR is given ).
Regards
Ankush

Hi @Ankush 

Configure core to 32 bit width and try using first 32 pins of 64 bit xdc.
