Connections and Interfaces or B2B Pin's which are accessible by User
  -->

B2B Connector

The TEB0729 Carrier Board's Board-to-Board Connectors (B2B) have the same pin-assignment as the mounted Zynq SoM due to its hermaphroditic structure. By this connectors, the MIO- and PL-IO-bank's pins and further interfaces of the Zynq SoM can be accessed. A large quantity of these I/O's are also usable as  LVDS-pairs. The connectors provide also VCCIO voltages to operate the I/O's properly.

...

Table 2: General overview of PL I/O signals and SoM's interfaces connected to the B2B connectors.

VG96 Connector

The TEB0729 Carrier Board has soldering pads provides as place-holders to mount VG96 connectors J8 and J9 to get access the PL-IO-bank's pins and further interfaces of the Zynq SoM. With mounted VG96 connectors, SoM's IO's are available to the user, a large quantity of these I/O's are also usable as  LVDS-pairs.

...

Table 3: General overview of PL I/O signals, SoM's interfaces and control signals  connected to the VG96 connectors.

HW-modification Concerning Reset-Signals

¹⁾ The pins with the schematic net names 'NRST_IN' (JB2-89) and 'NRST_OUT' (JB2-91) are swapped as part of a HW-modification to rework the Reset-signals of the Carrier-Board in conjunction with the TE0729 SoM.

Refer to the SC CPLD documentation, section "Watchdog" to get further detailed information about the Reset-functionality of the Carrier Board and SoM before and after the HW-modification and the required SC CPLD firmware revision of the TE0729 SoM for each version of the SoM.

JTAG Interface

JTAG access to the mounted SoM is provided through B2B connector JB2 and is also routed to the XMOD header JB3. With the TE0790 XMOD USB2.0 to JTAG adapter, the Zynq chip on the mounted SoM can be programed via USB2.0 interface.

...

Table 4: JTAG interface signals.

UART Interface

UART interface is available on B2B connector JB2. With the TE0790 XMOD USB2.0 adapter, the UART signals can be converted to USB2.0 interface signals:

...

Table 5: UART interface signals.

I²C Interface

Two I²C interfaces are provided on B2B connector JB2. I²C0 interface is connected to the Configuration EEPROMs U1 and U2 and is dedicated to these on-board peripherals. Interface I²C1 is routed to the VG96 connector J9 and is available to the user for general purposes:

...

Table 6: I²C interface signals.

SD IO Interface

The SD IO interface of the SoM's Zynq chip (MIO-bank) is routed to the on-board MicroSD Card socket J1. By this interface, the Zynq chip can be booted from an inserted MicroSD Card:

...

Table 7: SD IO interface signals.

USB2.0 Interface

The TEB0729 Carrier Board is equipped with a Micro USB2.0 B (receptacle) socket J11 with board-revision TEB0729-02B, USB2.0 Type A socket is fitted on board-revision TEB0729-02A.

...

Table 8: USB2.0 interface signals and connections.

Gigabit Ethernet Interface

The TEB0729 Carrier Board is fitted with one RJ-45 Gigabit Ethernet Magnetic jack J3. The MegJack has two integrated LEDs (both green), its signals are routed as MDI (Media Dependent Interface) to the B2B connector JB2, where they can be accessed by the GbE PHY transceiver of the mounted SoM:

...

Table 10: GbE SGMII signals and connections.

10/100-BaseT Ethernet Interface

The TEB0729 Carrier Board is also fitted with two additional RJ-45 MegJacks providing 10/100-BaseT Ethernet interfaces. This interfaces are routed to the B2B connector JB2

...

Table 11: 10/100-BaseT Ethernet interfaces signals and connections.

XMOD FTDI JTAG-Adapter Header

The JTAG interface of the mounted SoM can be accessed via header JB3, which has a 'XMOD FTDI JTAG Adapter'-compatible pin-assignment. So in use with the XMOD-FT2232H adapter-board TE0790 the mounted SoM can be programmed via USB interface. The TE0790 board provides also an UART interface to the Zynq SoM which can be accessed by the USB2.0 interface of the adapter-board while the signals between these serial interfaces will be converted. The adapter-board offers also two GPIO's, one with an indication LED (pin JB3-9 (E)) and another one with a low-active push button (pin JB3-11 (G)).

Configuration EEPROM

The TEB0729 Carrier Board is equipped with two Configuration EEPROMs U1 and U2 from Microchip.

...

The Configuration EEPROMs are connected to the I²C0 interface of the Zynq's MIO-bank via B2B connector JB2.

4-bit DIP-switch

Table below describes DIP-switch S2 settings for configuration of the mounted SoM:

...

TE0729 Bootmodes

If TE0729 is mounted, following bootmodes can be configured by setting the DIP-switches S2-2 and S2-3:

...

The selected bootmode via DIP-switch S2 depends also on the current configured SC CPLD firmware on the mounted SoM and may vary.

VCCIO Setting Jumper

The Carrier Board VCCIO for the PL IO-banks of the mounted SoM are selectable by the jumpers J6 and J7.

...

Table 16: VCCIO jumper settings.

RTC Buffer Voltage Supply Header

The buffer voltage of the SoM's RTC can be supplied through the header J2. Refer to the SoM's TRM for recommended voltage range and absolute maximum ratings.

Push Button

The Carrier Board's push button S1 is connected to the 'NRST_IN' signal, the function of the button is to trigger a reset of the mounted SoM by driving the reset-signal 'NRST_IN' to ground.

On-board LEDs

Power Consumption

The maximum power consumption of the Carrier Board depends mainly on the mounted SoM's FPGA design running on the Zynq chip.
