will automatically configure these pins to be trace signal pins when the
configuration option Acquire Trace on GO (
TRCAQU) is set to ON. The AMCC 405
trace signals are enabled only when the AMCC 405 is actually executing code.
2.3.2 Signal requirements for the AMCC 440 Processor
Wind River Trace for the AMCC 440 requires that all of the trace signals from the
440 processor be properly connected to the trace interface 38-pin Mictor connector.
The trace signals required are TRCCLK, TS0, TS1, TS2, TS3, TS4, TS5, TS6, ES0, ES1,
ES2, ES3, ES4, BS0, BS1, BS2, and GND. The trace signals are high-speed signals, so
be extremely careful when connecting these signals from the AMCC 440 processor
to the trace interface Mictor connector. The AMCC 440 trace pins are dual-mode
multiplexed pins that can be configured as trace signals or as GPIO[18:31] signals.
Wind River ICE SX automatically configures these pins to be trace signal pins
when the configuration option Acquire Trace on GO (
TRCAQU) is set to ON. The
AMCC 440 trace signals are enabled only when the AMCC 440 is actually
executing code.
2.3.3 Signal Requirements for ColdFire Processors
Wind River Trace requires that all trace signals from the ColdFire processor be
properly connected to the trace interface 26-pin BDM connector.The trace signals
required are described in Table 2-1.
NOTE: These pins must not be re-configured as GPIO pins by the application code.
