The Trenz Electronic TE0703 Carrier Board is a base-board for 4x5 SoM's, which exposes the MIO- and the PS/PL-pins of the SoM to accessible connectors and provides a whole range of on-board-components to test and evaluate Trenz Electronic 4x5 SoM's.
See page "4 x 5 cm carriers" to get information about the SoM's supported by the TE0703 Carrier Board.
Board is shipped in following configuration:
Switch | Position | Description |
---|---|---|
S2-1 | ON | Mode control MC1. |
S2-2 | ON | Mode control MC0. |
S2-3 | ON | JTAG enabled for B2B JB1 connector. |
S2-4 | OFF | Boot mode set to QSPI. |
Different delivery configurations are available upon request.
For detailed information about the B2B pin out, please refer to the Master Pin-out Table.
Micro SD card socket is connected to the B2B connector through a Texas Instruments TXS02612 SDIO Port Expander for voltage translation. The Micro SD card has 3.3V signal voltage level while Xilinx Zynq MIO bank uses 1.8V for VCCIO.
TE0703 has on-board dual high-speed USB-to-multipurpose UART/FIFO controller from FTDI. Channel A can only be used in simple UART mode, channel B can be used in UART, FIFO, JTAG (MPSSE) or high-speed serial modes. 256-byte serial EEPROM is available for storing custom configuration settings of the FT2232H chip. Contents of this EEPROM can be programmed with the FTDI provided software tools which can be downloaded from FTDI website.
On-board Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LEDs PHY_LED1 and PHY_LED2 are both routed to System Controller CPLD bank 1.
TE0703 board has two physical USB sockets:
JTAG access to the System Controller CPLD and Xilinx Zynq chip on the SoM is provided via mini-USB JTAG interface (FTDI FT2232H) and controlled by DIP switch S2-3. JTAG signals from System Controller CPLD to the JB2 connector are routed as follows:
JTAG Signal | B2B Connector Pin |
---|---|
TCK | JB2-100 |
TDO | JB2-98 |
TDI | JB2-96 |
TMS | JB2-94 |
There are four on-board LEDs:
LED | Color | Description |
---|---|---|
D1 | Red | FTDI UART receive activity. |
D2 | Green | FTDI UART transmit activity. |
D3 | Red | CPLD signal FL_0. |
D4 | Green | CPLD signal FL_1. |
LEDs D3 and D4 are also connected to the B2B connector JB2 pins FLED1 and FLED2 respectively and can be controlled by SoM FPGA firmware.
Switch | ON | OFF | Notes |
---|---|---|---|
S2-1 | User configurable, routed to CPLD | User configurable, routed to CPLD | |
S2-2 | User configurable, routed to CPLD | User configurable, routed to CPLD | |
S2-3 | JTAG enabled for B2B connector JB2 | JTAG enabled for CPLD | |
S2-4 | Boot from SD Card | Boot from QSPI flash on module |
Power supply with minimum current capability of 3A for system startup is recommended.
TE0703 needs one single power supply with nominal of 5V.
Power Input Pin | Max Current |
---|---|
VIN | 4A |
Typical power consumption for TE0703-05 + TE0715-01 module with SD micro card inserted, ethernet connected, link up, system booted into Linux prompt and idling is 5V / 0.55A.
It is not allowed to feed any voltage to any external I/O pin before there is no power indication on M3.3VOUT pins. Presence of 3.3V on B2B JB2 connector pins 9 and 11 indicates that module is properly powered up and ready.
If any of the VCCIOA, VCCIOB, VCCIOC or VCCIOD will be powered through external connectors J1 or J2, then corresponding VCCIO jumper should also be removed altogether, see next chapter.
Refer to the 4x5 Module Integration Guide for VCCIO voltages options.
