Debug System
3.17.1
OCDS1
The OCDS1 signals are connected to the IDC16 plug (X401). They work with the port supply of Microcontroller (+5V
default or +3,3V). For pinout of the connector see
. You can connect any debugger to this connector.
The signals /BRKIN and /BRKOUT are not connected per default. If you need this signals in the connector then
assemble R424 and R425 or R426 with a 0R resistor.
If you connect a debug hardware make sure that the miniWiggler JDS (see
) is not
activ (ACTIV LED is off) and on the DAP connector (X402) is no hardware connected or the hardware is tristated.
If the ACTIV LED is on, then stop the active DAS Server ’UDAS’ and/or remove the USB connection to the PC.
If R214 up to R216 not assembled then the connector is not usable.
3.17.2
DAP
The board comes with a DAP connector (X402). For pinout of this connector see
. You can connect a
DAP hardware here. If you use this connector make sure that the miniWiggler JDS is not activ (ACTIV LED is off)
and a connected OCDS1 hardware is disconnected or tristated.
3.17.3
DAP_SCR
Additional DAP connector (X406) is connected to DAP_SCR. This DAP can be used as private DAP connection to
the standby controller. For pinout of this connector see
. You can connect a DAP hardware here. This
DAP use P33.6 and P33.7 which are connected to LED on the board. Maybe it is necessary to remove R393 and
R394 if the speed of the connection is not fast enough.
3.17.4
High speed with DAP
For use the DAP connection with 160 MHz you need to remove 3 resistors to have a very short connection between
device and connector. On the TC3X4L Triboard this 3 resistors are R214, R215 and R216 for DAP (red marked in
). This resistors needs to be removed.
Important: When the resistors are removed then only the DAP connector on the board can be used. The on board
wiggler and the OCDS1 connector couldn’t be use (are disconnected) in this case, also the DAP/JTAG part of the
ETK connector couldn’t be used.
All resistors are red marked in the following figure:
