Tool Revision Adds Arm Cortex-M Trace and Debug Support

Lauterbach has announced a new revision of their debug and trace probes for Cortex-M based devices. As Cortex-M processors are becoming clocked at greater and greater frequencies, the trace port clocks must also increase to keep pace and prevent loss of valuable data. To provide developers with a more future-proof solution to this perpetual cycle of increasing frequency, the new High-Speed Whisker cables are designed to work with trace clock frequencies of up to 200 MHz across trace ports ranging from 1-bit to 4-bits wide, giving a total trace port bandwidth of up to 200 MB/s.
With increased trace clock speeds comes an increased risk of signal misalignment when parallel trace pins are sampled. The High-Speed Whisker cable includes the innovative auto-focus technology that not only detects the trace port clock frequency but can also adjust the optimum sampling points of each pin to negate any alignment issues in the timing of the data signals. The points where each signal contains valid data, or data eyes, for each pin can be displayed in the TRACE32 PowerView software.

Detailed information about jitters, rising and falling edges is also displayed and users are provided with the capability of manually adjusting the sampling point of each signal. Once configured, these sampling points may be saved and recalled for future use of the tools on this target. The High-Speed Whisker cable will start shipping in January 2019 for TRACE32 µTrace and CombiProbe. Customers who purchased these units during 2018 may request a free upgrade.

TRACE32 Extends embOS Awareness to the Renesas RH850

Lauterbach has announced that it has extended the kernel awareness for the embOS RTOS from SEGGER Microcontroller to the RH850 Family of microprocessors from Renesas Electronics. TRACE32, the class leading debug tools from Lauterbach, already supports embOS on ARM, PowerPC, RX, SH and NIOS-II families and this tried and tested technology has now been extended to include RH850.

The embOS awareness plugin for TRACE32 allows the developer to visualise RTOS resources and objects such as task lists, mailboxes, timers and semaphores. Developers are free to investigate interrupt routines, drivers and application code all from within the familiar environment of TRACE32. When the awareness is configured, extra features become available, for instance the setting of task aware breakpoints.

All MPUs of the RH850 Family provide dedicated counter registers which can be accessed non-intrusively by the TRACE32 debugger. These can be configured to display minimum, maximum and mean runtimes for a user marked block of code or the runtimes of various tasks in the embOS system. If the target provides off-chip trace capabilities, TRACE32 can record processor cycles and can be configured to collect data on task switches. Using this information, a detailed analysis of the program history, including task switches, can be viewed.

All features of the TRACE32 awareness for embOS do not require any additional target configuration or any hooks or patches within the RTOS itself. The philosophy of TRACE32 is for the application to behave exactly the same in the debug environment as on the final product; only this way can 100% certainty of testing be achieved.

Tracealyzer 3.1 Offers Support for Trace Streaming Over USB

Percepio AB recently released Tracealyzer 3.1, which is a trace tool that supports RTOS trace using just a standard USB cable. You can increase your development speed by using Tracealyzer for debugging, validation, profiling, documentation, and training. Percepio-Tracealyzer

The trace recorder library is now easier to configure for streaming over custom interfaces, and includes support for USB streaming on STM32. (It can be adapted for other microcontrollers.) USB offers excellent performance for RTOS tracing and over 600 KB/s has been measured on an STM32 using USB 2, several times more than required. Other stream ports include TCP/IP and SEGGER J-Link debug probes. Tracealyzer 3.1 can also receive trace streams via Windows COM ports (e.g., from USB CDC connections), UART connections, or any virtual COM port provided by other target interfaces.

Tracealyzer 3.1 can identify memory leaks in systems that use dynamic memory allocation. It can record memory allocation events (e.g. malloc, free) from multiple operating systems, and it can display such allocations that have not been released. Since the memory allocation events are linked to the task trace, you quickly find the context of the allocation and investigate the problem. The recorder library simplifies integration and now provides a common API for both streaming and snapshot recording.
