Hi Lautaro, The clocks section lists the clock ports you want to have on a block. The rfnoc_chdr and rfnoc_ctrl clocks are required for all blocks. In the block's YAML, they must be provided in the list of clocks (see other blocks for example in https://github.com/EttusResearch/uhd/tree/master/host/include/uhd/rfnoc/blocks). In the device YAML (for example e310_rfnoc_image_core.yml), they are connected automatically to every block, so you don't need to specify them when connecting blocks unless you also want to use one of them for a different clock input. For example, you might want to drive the ce input of a block with rfnoc_chdr clock. The freq parameters aren't used currently, but it's intended to specify the frequency range of a clock.
I'm not familiar with the fosphor GRC code. As far as I know this hasn't been updated for E31x and UHD 4.
