Are you able to map an HPS IP Peripheral Signals to the
FPGA fabric, such as a UART controller?
In the case of Arria10SX Dev Kit, routing the DB9 RS232 port (of the FPGA fabric) to the HPS uart controller. (in addition to the usb-to-uart port connected to the HPS; requiring a 2nd uart)
Seems I am able to choose if the signals are coming from FPGA or HPS dedicated/shared IOs in Platform designer --> HPS --> Pin Mux and Peripherals Tab.
But found a similar post which is implying this is not possible for A10SoC and requires an fpga-hps bridge with corresponding IPs in the FPGA fabric.
Some clarification would be appreciated.

Hello sir,
Let me check on this with our internal team.
I will come back to you soon,
Thanks

I think it is possible.
A10 devkit user guide mentions below.
However, HPS debug port connection depends on boot device. UART in NAND device connects to Shared I/O. UART in the other device connect to Dedicated I/O.
If you want to change this behavior, you need to change MAX V design. Please check schematics below.
Hope this might help.
Thanks
