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

...

selected with JTAGEN (DIP-S2-3).

...

Module FPGA/CPLD access can be switched

...

with PROGMODE which is driven by

...

CM0 (DIP-S2-2).

...

CM0 is pulled up with CPLD.

If used SoM on the carrier board is TE0715, CPLD of TE0703  must be programmed a different jed file to arrange CPLD JTAG pins correctly. This module is an exception.  For this purpose it is defined a generic parameter in VHDL code to switch JTAG pins differently as other SoM modules. There are two jed files. CPLD of TE0715 module with default jed file for CPLD of carrier board TE0703 can not be programmed. But optional jed file exists for this purpose. In both cases default or optional jed file the following table is valid:

S2-2S2-3PROGMODE (S2-2)JTAGEN (S2-3)Description
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. NOSEQ pin is either high impedance or is used as JTAG pin to program CPLD of TE0715 module. PGOOD pin can be set or reset by user. If CM0 or CM1 set to high (S2-2 or S2-1 OFF) , PGOOD will be set to high otherwise PGOOD is set to low.

Reset

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

Boot Mode

MODE

...

pin is sourced by

...

MIO0. MIO0 connected DIP S2-4 and B2B connector. MIO is pulled up with CPLD and can be set to GND via DIP. PGOOD pin will be used as second select pin for boot mode selection. In this case the following table can be considered:

ON00JTAG boot mode
OFFON10SD Card boot mode, PHY LEDs glow orange

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 switched to SD_CD and its status depends on SD_CD .

Appx. A: Change History and Legal Notices

Revision Changes

...

  • REV02 to REV03

    • Oscillator frequency is changed from 12.09 MHz to 24.18 MHZ.

    •  Access to CPLD of TE0715 with a generic parameter added. (For optional jed file to access CPLD of TE0715 module)

    • PGOOD used as second boot mode selector pin and connected to dip switch S2-1. PGOOD and MODE are boot mode selector pins.

    • S2-1 dip switch (CM1) functionality is changed.In HW PCB REV0 to REV04 is used for SD card detection but in HW PCB REV05 and REV06 is used to set or reset PGOOD.
    • MIO14 is connected to FTDI_RXD directly without depending on PGOOD.
    • CM1 (Dip switch S2-2) has no effect on MIO9 anymore. That means MIO9 is connected to SD_CD only and not to SD_CD and CM1.
  • REV02 to older REV01

    ...

      • Enable CPLD access to module CPLD over DIP
      • Add MIO0, SD_SEL, SD_CD, NOSEQ, PGOOD, 2LEDs, PHY LEDs
      • Debounce button
      • More status LED functionality
