In Vivado Design Suite 2013.2, there are known limitations of Preset Export/Import from XPS to IPI Zynq flow:
In IPI, the settings for UART is for separate MIO's; UART0 and UART1.
The default value of the BAUD rate for these settings is 115200 in IPI. When a user migrates from XPS flow with UART settings set to 9600, they would show as 115200 in IPI.
The UART0/UART1 settings need to be set to 9600 as needed by the user in the PS7 GUI of IPI.
In Vivado Design Suite 2013.3, the PS7 system in IPI will handle all preset files of XPS regardless of its version.
