Accessing FPGA FABRIC PINS from the HPS side

hii i bought the standard DE-10 SOC DEV BOARD , and i want to use the uart on the HPS side to communicate to a PC and once i get a char for example ‘1’ by the HPS uart i will turn on a gpio which its on the FPGA fabric side , is there a tutorial or example that can help me in this subject :slight_smile:
