Version Found: v1.6
Version Resolved and other Known Issues for v1.6 core: See (Xilinx Answer 52797)
The Virtex-7 and Kintex-7 FPGA GT wrappers generated with 6.25Gbaud x2 and 6.25Gbaud x4 core configurations might cause the link to train down. This issue is seen only in the wrappers for production devices and not on IES and GES wrappers.
Note: v1.6 is the first version of the core that comes with Virtex-7/Kintex-7 FPGA production device wrappers.
This is a known issue to be fixed in a future release of the core.
To avoid this issue, generate the wrapper from the GT Wizard and replace the GT specific wrappers generated with the LogiCORE IP Serial RapidIO Gen2 v1.6 core with the ones generated from the GT Wizard.
NOTE: "Version Found" refers to the version where the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
