Zynq UltraScale+ MPSOC ZCU102 Evaluation Kit - Can I use Bank 66 and Bank 67 on a ZCU102 board for MIPI_DPHY_DCI I/O ?

Description

To use an HP I/O bank with the MIPI_DPHY_DCI I/O standard, the VRP of the I/O bank needs to be connected to ground via a 240 ohm resistor.

On the ZCU102 board, the VRP pin of Bank 66 and Bank 67 is NC. Is it possible to implement MIPI_DPHY_DCI I/O standard in Bank 66, Bank 67 of the ZCU102 board?

Solution

On the ZCU102 board, the VRP pin in Bank 66 & Bank 67 is not connected (NC). To use MIPI_DPHY_DCI on these banks, DCI Cascade must be used.

This requires the following command:

set_property DCI_CASCADE {slave_banks} [get_iobanks master_bank]

For example on the ZCU102 board, Bank 65 has a 240 ohm resistor connected to the VRP pin.

In this case, Bank 65 can be used as a DCI cascade master bank for Bank 66 and Bank 67.

set_property DCI_CASCADE {66 67} [get_iobanks 65]
