Hello
I am trying to set 4 ADCs (AD9083) to work with a single JESD quad and topology.
each AD9083 has 32 converters (16 channels of i,q) and use a single JESD lane.
The system works fine with a single lane but when scaling to 4 lanes it fails to realize it should work in multi-chip mode and I get this warning:

The parameter sets for FPGA:
It is possible that the tpl core is limited in number of converters it can handle, but the but width is was I am expecting to get.
Will appreciate any advice
Thanks
