AXI3 Lightweight Bridge

Hi All,

I have a question about the AXI3 Lightweight bridge coming from HPS toward FPGA portion...

How can I define a clock frequency for the AXI3 Lightweight bridge? I cannot find the appropriate field in the Qsys HPS section...

Thank you!

    The HPS2FPGA AXI Bridge has many periph_id registers. What are they used for? It's not so understood...

    You have to select the Bridge in the HPS configuration (I think first Tab in QSYS) and afterwards connect a clock within the Top-Level Qsys-Design to it.
