Page 5: Trace Overview
Chapter 1 Trace Overview 1 Trace Overview The MB86R01 has an integrated ETM9CS Single Macrocell for real-time tracing. With the ETM you can capture instructions and data executed by ARM926EJ-S core without influencing the execution. The trace data helps to find bugs more easily and allows stepping (both forwards and backwards) in the code. -

However, the GreenHills Super Trace Probe (STP) has a special connector. Therefore an adapter is needed to connect both devices. The adapter board can be ordered from Fujitsu. Furthermore, the schematic and layout are available on request. Figure 1 Adapter Board an-mb86r01-trace-rev0-01.doc... -

>TraceOptions from the top menu. Then select Target Specific Options to open the Trace options menu. A detailled parameter description can be found in the GHS Debugging book in chapter 19 “Collecting and Using Trace data”. Here is a small summary: an-mb86r01-trace-rev0-01.doc - 9 -© Fujitsu Microelectronics Europe GmbHError! Reference source not found. - Page 10 FIFO is close to overflowing. This method is only available with ETMv3.x targets. Suppressing data trace is less effective at preventing the FIFO from overflowing than stalling the CPU, but has no impact. an-mb86r01-trace-rev0-01.doc - 10 - © Fujitsu Microelectronics Europe GmbH...

Due to this, the trace output is corrupted and it is not possible to reproduce the complete program flow. However if the error is isolated and filters are used, it is possible to trace all data of interest. an-mb86r01-trace-rev0-01.doc - 12 - © Fujitsu Microelectronics Europe GmbH... -
