Hello,

I'm a noob on stm32 and keil, I'm not sure the problem is my operation in keil or my configuration about stm32 and x-cube-mems1. Please help with the details.

I successfully run the DataLogFusion example in Nucleo-F401RE and X-NUCLEO-IKS01A2. But when I try to use MotionFX lib in my custom board project, I get this issue.

In debug session, the program could not STEP OVER the function - MotionFX_initialize().

Using

1. Custom board using STM32F401CEUx

2. MotionFX V2.0.0, included MotionFX200_CM4F_Keil_ot.lib

3. Code generated by STM32 CubeMX 4.22, STM32Cube FW_F4 V1.16.0

Hello,

please enable clock for CRC unit in the microcontroller, it is needed for the algorithm initialization.

Yes, it works by adding __CRC_CLK_ENABLE();
