Hi, In RFNOC image core files I saw that BSP connection? what's them and what's the difference between ordinary connections and BSP connections... thanks in advance *BSP connections:* # BSP Connections - { srcblk: radio0, srcport: ctrl_port, dstblk: _device_, dstport: ctrlport_radio0 } - { srcblk: radio1, srcport: ctrl_port, dstblk: _device_, dstport: ctrlport_radio1 } - { srcblk: replay0, srcport: axi_ram, dstblk: _device_, dstport: dram } - { srcblk: _device_, srcport: x300_radio0, dstblk: radio0, dstport: x300_radio } - { srcblk: _device_, srcport: x300_radio1, dstblk: radio1, dstport: x300_radio } - { srcblk: _device_, srcport: time_keeper, dstblk: radio0, dstport: time_keeper } - { srcblk: _device_, srcport: time_keeper, dstblk: radio1, dstport: time_keeper } *Other connections:* # ep0 to radio0(0) - RFA TX - { srcblk: ep0, srcport: out0, dstblk: duc0, dstport: in_0 } - { srcblk: duc0, srcport: out_0, dstblk: radio0, dstport: in_0 } # radio(0) to ep0 - RFA RX - { srcblk: radio0, srcport: out_0, dstblk: ddc0, dstport: in_0 } - { srcblk: ddc0, srcport: out_0, dstblk: ep0, dstport: in0 } # radio0(1) to ep1 - RFA RX - { srcblk: radio0, srcport: out_1, dstblk: ddc0, dstport: in_1 } - { srcblk: ddc0, srcport: out_1, dstblk: ep1, dstport: in0 } # ep2 to radio1(0) - RFA TX - { srcblk: ep2, srcport: out0, dstblk: duc1, dstport: in_0 } - { srcblk: duc1, srcport: out_0, dstblk: radio1, dstport: in_0 } # radio1(0) to ep2 - RFA RX - { srcblk: radio1, srcport: out_0, dstblk: ddc1, dstport: in_0 } - { srcblk: ddc1, srcport: out_0, dstblk: ep2, dstport: in0 } # radio0(1) to ep3 - RFA RX - { srcblk: radio1, srcport: out_1, dstblk: ddc1, dstport: in_1 } - { srcblk: ddc1, srcport: out_1, dstblk: ep3, dstport: in0 } # ep4 to replay0(0) - { srcblk: ep4, srcport: out0, dstblk: replay0, dstport: in_0 } # replay0(0) to ep4 - { srcblk: replay0, srcport: out_0, dstblk: ep4, dstport: in0 } # ep5 to replay0(1) - { srcblk: ep5, srcport: out0, dstblk: replay0, dstport: in_1 } # replay0(1) to ep5 - { srcblk: replay0, srcport: out_1, dstblk: ep5, dstport: in0 }

The BSP (board support package) connections are the product-specific ports, like the radio, timekeeper, DRAM, etc. You can identify them because they always go to or from the "_device_". Clocks also come from the _device_. You can see a list of ports on each product by looking at the BSP YAML files here: https://github.com/EttusResearch/uhddev/tree/master/host/include/uhd/rfnoc/core The other connections are between blocks, or between blocks and stream endpoints.
