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 AX7010 FPGA development board.

Part 6.6: SD Card Slot

The AX7010 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:
