Functional Description

JTAG

JTAG signals routed directly through the CPLD to module in B2B connector. Access between CPLD and module can be multiplexed via JTAGEN (logical one for CPLD, logical zero for module).

TE0703 CPLD can be select with JTAGEN (DIP-S2-3).

Module FPGA/CPLD access can be switched with PROGMODE which is driven by CMD0 (DIP-S2-2).CMD0 is pulled up with CPLD.

S2-2S2-3PROGMODEJTAGENDescription
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 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

WEEE

Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).

Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
