JTAG Chain
7.1.1 JTAG Devices
The JTAG chain of the SBC-S32V includes the S32V234 processor only. The
JTAG port is directly connected to the connector “JTAG”.
7.1.2 JTAG Connector
The JTAG connector provides all standard JTAG signals for an ARM interface on a
2x5 pin header. Pin 7 of this header usually connects the return clock RTCK and is
not used on the CRX-S32V. For boundary scan purposes, it can be used to control
the TRST# signal. As this feature is not standard due to the 10 pin ARM interface,
it can be disconnected by the header JRS. The header JRS is located directly be-
hind the reset push button.
