Dear all,
Let me inform about latest MC software product update:
- New application note AN5321 Safety Class B with PMSM Sensorless Drive is fully available on NXP web pages including application software AN5321SW.
- NXP Embedded Software Libraries 4.3 (CM0+, CM4, CM7) – RTCESL-CM-4.3
AN5321SW V1.0.0
------------------------------------------------------------------------------------------------------------------------------------------
- List of the implemented IEC/UL 60730 tests:
- CPU registers—tested for the “stuck at” condition.
- Program counter—tested for the “stuck at” condition.
- Flash memory—tested for the single bit error and multiple bits error.
- RAM—tested for the “stuck at” condition and direct coupling faults.
- Clock source—tested for the “wrong frequency” condition.
- Watchdog—tested for wrong frequency and proper functionality.
- Application stack—the same test as for the RAM and the overflow and underflow conditions.
- Interrupt handling and execution—the interrupts are tested for too frequent or too infrequent executions. The program flow test is also integrated within this component.
- Sensorless field-oriented control of PMSM
- Supported MCUs: KV31
- Supported HW platform: TWR-KV31F120 + TWR-MC-LV3PH + Linix motor
The application is based on PMSM SDK2.0 reference project.
Supported IAR

-
- Bug fixes and optimizations:
- The AMCLIB_TrackObsrv_F16 used incorrect calculation.
- Functions GFLIB_CtrlPIpAW_F16 and GFLIB_CtrlPIDpAW_F16 did not stop the integration process when the input flag was set.
- Functions GFLIB_CtrlPIpAW_F16 and GFLIB_CtrlPIDpAW_F16 had an integration part limitation issue.
- The GFLIB_Integrator_F16 was optimized.
- The function GFLIB_VectorLimit1_F16 had saturation issue
- The inoperative limitation in the GFLIB_Integrator_FLT function.
- The wrong initialization in the GDFLIB_FilterMAInit_F16 function.
- The functions GMCLIB_ElimDcBusRipFOC_F16, GMCLIB_ElimDcBusRipHw_F16sas had limitation issues.
- The functions PCLIB_Ctrl2P2Z_F16, PCLIB_Ctrl3P3Z_F16, PCLIB_CtrlPID_F16, PCLIB_CtrlPI_F16, PCLIB_CtrlPIandLP_F16 did not use the MAC operations.
