Silicon Labs provides virtual COM port (VCP) drivers for host PCs. These
drivers allow the CP2102GM USB-UART bridge device to be displayed as a
COM port in communications application software, such as TeraTerm or
HyperTerminal. The VCP device driver must be installed before the PC host
establishes communication with the AX7020 FPGA development board.

Part 6.6: SD Card Slot

The AX7020 FPGA Development Board contains a Micro SD card
interface to provide user access to the SD card memory, the BOOT program for
the ZYNQ chip, the Linux operating system kernel, the file system and other
user data files.
The SDIO signal is connected to the IO signal of the PS BANK501 of
ZYNQ. Since the VCCMIO of the BANK is set to 1.8V, but the data level of the
SD card is 3.3V, connected through the TXS02612 level shifter. The schematic
of the Zynq7000 PS and SD card connector is shown in Figure 6-10:
