CMSIS 5.1.0

Known Issues

• CMSIS-RTOS2
  • RTX5 pre-compiled library build for Cortex-M7 uses wrong interrupt priorities. This leads to a dysfunctional RTOS schedeuling.
    Error: Occasional hard faults or system crashes.
    Workaround: Manually fix interrupt priorities after osKernelInitialize or select RTX5 source instead of library.
• CMSIS-DSP
  • __CLZ redefined for IAR compiler on Cortex-M0 in arm_math.h
    Error: function "__cmsis_iar_clz" has already been defined
    Workaround: Remove __CLZ implementation from arm_math.h lines 581-599
• CMSIS-Core(A)
  • Various intrinsic functions wrongly/incompletely implemented.
    Error: Compiler errors or undef faults
    Workaround: Use develop branch until maintenance release is available.
