Zynq-7000 AP SoC, DDR - DCI does not work

描述

DDRIOB has issues with the DCI state machine and cannot dynamically determine the setting for proper impedance matching. This results in DDR2/DDR3 input termination and LPDDR2 output drive strength not matched to the DCI reference resistors.

解决方案

Impact: Minor.

Work-around: None.

Configurations Affected: Systems using the DDR memory controller (DDR2, DDR3 and LPDDR2)

Device Revision(s) Affected: Refer to the Zynq-7000 AP SoC - Design Advisory Master Answer Record (Xilinx Answer 47916).
