Issue with SysTick 1ms Timing Mechanism in S32K3 Chip with RTD 6.0.0

[chenwilsoft]

I am using RTD 6.0.0 and have set the System Timer Clock Frequency in BaseNXP. However, the parameter SystemCounterFreq passed in the OsIf_Timer_System_Internal_Init function is not being used. When the OS is not used, SYSTICK_MAX is assigned to the RVR register. As a result, SysTick cannot implement a 1ms timing mechanism.

Hi@chenwilsoft

I read the implementation of this function, and it is indeed the same as what you said. If "USING_OS_FREERTOS" is not defined, then its default value will be set to the maximum value and the user-defined value will be ignored.
