RFNoc split stream block missing

Dear all

Is there a reason why there is no SplitStream block available anymore in the latest uhd rfnoc driver (UHD_003.010.rfnoc-314-gf773e72b)? Although I find some traces of a SplitStream block in the FPGA source code as well as in some *.xml block definition files, the output of ./uhd_usrp_probe -init-only shows some other available rfnoc-blocks, but no sign of splitstream. Is there an easy way to re-enable this block?

Thanks

Marc

Hi Marc,

this means that the block wasn't instantiated in the stock FPGA image.
You can enable it by modifying the RFNoC verilog file[1] that lists all
the blocks that are going to be included in the FPGA image, and
resynthesize the image, and load it onto the X3x0.

Best regards,
Marcus

source tree on the rfnoc-devel branch
