MicroTrace for Cortex™-M

A low-cost debugger for the Cortex-M family are available from Lauterbach. Due to the high market penetration of Cortex-M processors an all-in-one solution has been developed, that will provide the following features:

MicroTrace Characteristics

• Support for more than 1000 different Cortex-M processors
• USB 3 interface to the host computer
• Standard JTAG, Serial Wire Debug, and cJTAG
• 256 MByte trace memory
• 34-pin half-size connector for target hardware and adapters for a wide variety of other connectors
• Voltage range 0.3V to 3.3V, 5V tolerance

Debug Features

• C/C++ debugging
• Simple and complex breakpoints
• Read and write memory during program runs
• Flash programming
• OS-aware debugging
• Multicore debugging of two or more Cortex-M cores

Trace Features

• 4-bit ETMv3 in Continuous mode
• ITM over TPIU and Serial Wire Output
• Multicore tracing
• Streaming trace information to the host computer for long-term tracing, streaming rate up to 100 MByte/s
• Analysis of task and function runtimes
• Code coverage analysis
• Trace evaluation even during recording
• Energy measurement using TRACE32 Analog Probe

As with all Lauterbach products, μTrace is controlled by the TRACE32 PowerView GUI.

PCAN-Explorer 6 – CAN FD, Trace Playback and More

Communicate with CAN and CAN FD Busses

The professional Windows software PCAN-Explorer, a program for observation, control, and simulation of CAN busses, has been released as version 6. Besides CAN 2.0 A/B, the PCAN-Explorer 6 now also supports the CAN FD standard with up to 64 data bytes per CAN message. Another new feature is the playback of previously recorded CAN traces on a connected CAN bus.

The configuration of the symbolic representation of CAN messages has also been revised. Signals are used to define the representation of the arising payload and then are assigned to the different CAN messages. Previous symbol definitions are still applicable and can be converted to the new format if required.

In general, the use of flexible, configurable filters for incoming and outgoing CAN messages and also for recordings is possible. The automation of small tasks or complex processes is done using macros or VBScript. The functionality of the PCAN-Explorer 6 can be extended by add-ins. PEAK-System, for example, offers a plotter, an instruments panel, CANdb import, and J1939 support.

Upgrade Details

Customers of the PCAN-Explorer 5 receive an upgrade to version 6 for the price difference, depending on the date of purchase of the previous version. Contact us for more info.
