5.3 UART to USB
The board has one UART interface connected for communication with the HPS. This interface doesn’t support HW flow control signals. The physical interface is implemented by UART-USB onboard bridge from a FT232R chip to the host with an USB Mini-B connector. More information about the chip is available on the manufacturer’s website, or in the directory \Datasheets\UART TO USB of DE10-Advanced system CD. Figure 5-2 shows the connections between the HPS, FT232R chip, and the USB Mini-B connector. Table 5-4 lists the pin assignment of UART interface connected to the HPS.
