Description

The following error occurs when attempting to set the bitgen option "SPI_32bit_addr" for a Zynq device in ISE Design Suite 14.7:

ERROR:Bitgen:38 - Unknown command line option "spi_32bit_addr". Please consult the Command Line Tools User Guide for the appropriate command-line options

On page 245 of the Command Line Tools User Guide (UG628), it shows that the "SPI_32bit_addr" bitgen option is supported for 7 series and Zynq devices.

So why does this error occur?

Solution

The "SPI_32bit_addr" bitgen option is not supported for Zynq devices. The user guide (UG628) is incorrect and will be corrected in a future revision of the document.
