Hi,


You need to use the RS232 IP in platform design and connect this IP using hps2fpgaslaves with hps ip. assign the base address and pin assignments for RS232 ip(RX & TX pins).


Later, in linux add this rs232 entry in your device tree.


For this I suggest you to refer the Cyclone V GHRD/GSRD on rocketboard. This will help you how the design got created and the software requirement.

I’m using SOC, DE-10 nano.
Can't I just receive data via GPIO wired connection?
