STEVAL-STWINBX1 not receiving telemetry from EVLSPIN32G4-ACT

I am following https://www.st.com/resource/en/product_presentation/evlspin32g4-act-and-stwinbox-high-speed-datalogging-for-motor-control-and-sensors-quick-start-guide.pdf using hardware STEVAL-STWINBX1+EVLSPIN32G4-ACT 

 

https://github.com/STMicroelectronics/stdatalog-pysdk.git v1.5.0 stdatalog_MC_GUI.py is able to start/stop the motor operated in sensorless mode, correct GUI view and .dat file stored for all onboard sensors. But enabling slow/fast motor telemetries leads to error message: 

“HSDatalogApp.stdatalog_gui.HSD_GUI.HSD_Controller - ERROR - No data from fast_mc_telemetries Component.”

 

For suggestion “Restart the acquisition lowering component ODR to acquire data correctly.”, I tried to only enable one data item in slow telemetry, and had the same failure.

 

FW build env for both PMSM and STWIN.box:

  • MotorControl Workbench_6.3.0
  • STMCubeIDE 2.1.1
  • STMCubeMX 6.12
    • STM32 FW V1.5.2

When importing the STWIN.box FW project, among three projects(DATALOGMC, DATALOGMC_CubeAI, DATALOGMC_NanoEdgeAI) in STM32CubeFunctionPack_DATALOGMC_V2.2.1, I selected DATALOGMC.

 

Misc:

  • Flex cable STEVAL-FLTCB04 is connected, being able to start/stop the motor from stdatalog_MC_GUI.py confirms the electrical connection.
  • Motor Pilot can also control EVLSPIN32G4-ACT

 

I guess there might be a compile/run time switch to enable the telemetry from EVLSPIN32G4-ACT. I tried but wasn’t successful in finding such instruction. Many thanks in advance for your suggestions.
