Tracealyzer with IAR

I work on a project which uses Renesas MCU. The IAR is 9.10. I followed FreeRTOS — Trace Recorder 4.8.0 documentation to setup Tracealyzer with IAR.
Here are what I did:

  • Copy the TraceRecorder files to my project folder
  • Added the files and folders to my project
  • Added the path in the project options
  • In trcConfig.h:
    o add #include “bsp_api.h” and comment out #error “Trace Recorder: Please include your processor’s header file here and remove this line.”
    o updated #define TRC_CFG_HARDWARE_PORT TRC_HARDWARE_PORT_ARM_Cortex_M
  • In trcKernelPortConfig.h: #define TRC_CFG_FREERTOS_VERSION TRC_FREERTOS_VERSION_10_4_3
  • In FreeRTOSConfig.h: #define configUSE_TRACE_FACILITY (1)
  • In the initialization of my project before any task started, call: xTraceInitialize(); xTraceEnable(TRC_START);
  • The project build fine. I loaded the firmware on my device.

I try to capture the snapshot from Tracealyzer. But I got “Unable to fetch snapshot”. Could you please point out where I did wrong?
Thanks!

Assuming you are using RingBuffer streamport of Tracelyzer, you are probably not able to fetch the snapshot from the device. Try to follow these instructions from Percepio to save the snapshot. I’d also recommend to reach out to Percepio.
