...

Micro SD Card socket is not directly wired to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO port expander, which is needed for voltage translation due to the different voltage levels of the Micro SD Card and MIO bank 501 of the Xilinx Zynq 7000 chip. The Micro SD Card has 3.3V 3 V signalling, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8V8 V. !!! (card detect signal...)

...

Power supply with minimum current capability of 3A 3 A for system startup is recommended.

...

Typical value: TE0703-05 + TE0715-01 module. SD micro card inserted. Ethernet connected, link up. System booted into Linux prompt and idling. Average power consumption was 5V5 V / 0.55A55 A.

Initial Delivery State

Board is shipped in following configuration:

• VCCIO voltage selection jumpers are all set to 1.8V8 V.
• S1 switch configured as reset button in CPLD.
• Two VG96 backplane connectors are not soldered to the board, but they are included in the package as separate components.
• S2 DIP switches are configured as follows:
