The board has one UART interface connected for communication with the HPS on the TsoM
module. 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 TSOM-BB system CD.
Figure 4-3 shows the
connections between the HPS, 260-pinFT232R chip, and the USB Mini-B connector.
Table 4-4 lists the pin assignment of UART interface connected to the HPS of TsoM module.
