Dear Sir/Madam,


I am R&D a project based on S32K_BLDC_Sensorless platform and the software platform is "MTRDEVKSBNK144_S32DS".

I have a question now:

When my application starts running a motor, It always run in "stall" status. I found that the condition to enter stall status is : timer FTM2 overflow. It means if there is no any hall sensor signal changes within FTM2 timer, the app will enter stall status.

FTM2 timer period is fixed(longest period), my application want to more time to enter stall status. So how to make it?
