TriBoard Information

miniWiggler JDS
The miniWiggler JDS is a low cost debug tool which allows you access to the JTAG of the device. Make sure that
you have the latest DAS release. Debugging is possible via the DAS Server ‘UDAS‘. Please contact your prefered
debug vendor for support of DAS.
If you have connected the board to the PC and there runs the DAS server, then a working connection is visible via
the green ACTIV LED.
The status RUN LED is switched on/off through the DAS Server, depending on the used debugger (client).
IMPORTANT: Make sure that there is no or a tristated connection on X401 (OCDS1) and X402 (DAP) if the
ACTIV LED is on.
Per default the miniWiggler is connected to the DAP. If resistors R214, R215 and R216 assembled (default) then
the standard DAP is connected to miniWiggler. If all this resistors are not assembled then the miniWiggler can’t
be used. In this case only the DAP connectors X402 and X406 can be used. See
.

FlexRay™ (E-RAY)
The board has 2 IDC10 plugs for FlexRay™ Communication (channel A and B) with up to 10 Mbit/s. For the pinout
of the plugs see
. You can use a IDC female connector with crimpconnector, flat cable and SUB-D 9 plug
with crimpconnector to have a 1:1 adapter to SUB-D 9.
The transceiver are connected to the TriCore device via zero ohm resistors (R320 up to R324 and R340 up to R344)
which must be removed to use the ports outside.
ERAY-A can be connected to P02.0, P02.1 and P02.4. Transceiver for channel A can be enabled/disabled via P10.1.
The error state of transceiver channel A can be read out via P10.2.
ERAY-B is connected to P02.2, P02.3 and P02.5. Transceiver for channel B can be enabled/disabled via P20.10. The
error state of transceiver channel A can be read out via P20.9.
For more information look in the user manual for TC3X4 LQFP.
3.8
Serial Eeprom
The I
2
C via P15.4 and P15.5 of the TC3X4 is connected to a serial EEPROM with a size of 2KBit (2 x 128 x 8). The slave
address of this EEPROM is 0x50. The upper half of the array (80h-FFh) is permanently write-protected. Write
operations to this address range are inhibited. Read operations are not affected. This upper half contains a pre-
programmed EUI-48™ node address which can be used as MAC ID for Ethernet. The other 128 bytes are writable
by customer.
To disconnect (disable) the EEPROM remove resistor R348 and R349.
3.9
MultiCAN
On the board are two CAN transceiver connected to the CAN0 and CAN1 of TC3X4 LQFP. The transceivers are
connected to two IDC10 plug. For the pinout of IDC10 plug see
. You can use a IDC female connector with
crimpconnector, flat cable and SUB-D 9 plug with crimpconnector to have a 1:1 adapter to SUB-D 9.
The transceiver are connected to the TriCore device via zero ohm resistors (R301 up to R304 and R311 up to R314)
which must be removed to use the ports outside.
CAN0 can be used via P20.7 and P20.8 (CAN0 node 0, default) or P14.0 and P14.1 (CAN0 node 1). CAN1 can be used
via P13.0 and P13.1 (CAN1 node 0, default) or P00.0 and P00.1 (CAN1 node 0).
