OFFOFF11Access to TE0703 CPLD
OFFON10Access to CPLD of B2B Module
ONOFF01Access to TE0703 CPLD
ONON00Access to FPGA of B2B Module

Note: LED1,2,3,4 are on and PHY LEDs blink slow, if S2-2 is set to OFF.

Power

EN1 is set to one.

NOSEQ and PGOOD pulled up to VDD.

Reset

RESIN is driven by S1 (Push Button). Button is debounced.

Boot Mode

MODE Pin is sourced by MIO. MIO0 connected DIP S2-4 and B2B connector. MIO is pulled up with CPLD and can be set to GND via DIP.

S2-4MIO0Description
ON0def. SD-CARD Boot (for Zynq Modules), PHY LEDs glow orange
OFF1def. QSPI-Flash, PHY LEDs glow green

UART

Primary UART:

MIO14 is driven by BDBUS0 (FTDI RX).

BDBUS1 (FTDI TX) is driven by MIO14 MIO15 .

Secondary UART:

MIO13 is driven by X16.

X17 is driven by MIO12.

SD

SD selection is set to GND (SD Card slot).

MIO9 is SD_CD and CM1(S2-1). If S2-1 is ON, MIO9 is GND else status depends on SD_CD .

Note: PCB REV02,REV03,REV04 has no SD, set S2-1 to ON
