How to let FPGA get access to HPS pins

I've got an Arrow SOCkit and it has a USB-UART connected to the HPS' pins, but I'd like to access the UART from the FPGA logic. Is this possible? If so how is it done? Thank you!

Hi,

I'm having similar problem. I cannot get to output anything on the pins I loan to FPGA from HPS. I'm just trying to have four GPIO pins and make the LEDs of the HPS on SoCKit board blink. According to the schematic, GPIO 53:56 are connected to the LEDs. When I compile, Quartus is assigning the right pins to these LEDs. But I don't see the LEDs blink.

In the peripherals mux table, there is 'mux_select_1', mux_select_2' and 'mux_select_3'. What is this? What does it do?
