Unable to initialize MotionFX/MotionAC/MotionGC/MotionMC.

Hi,

I'm trying to use MotionFX for one of my projects but I can't initialize it.

I'm able to get the version of the library but once I initialize it, the board freezes.

MotionGC_Initialize(

10.0f

);

Here's a screenshot from the debugging process:

I'm not sure why r2 is not equal to r3, I've not been able find more details. Not sure how to solve it.

PS. I'm running this on the nrf52832 which I thought would work because it's the same Cortex M4F.

It is allowed to use these algorithms only with ST devices which means the combination of at least: a) one ST microcontroller and b) one device chosen by

You between a ST radio frequency connectivity device and a ST MEMS sensor integrated circuit. The algorithms available in X-CUBE-MEMS1 package will run only on STM32. Please check

!

If you want to run it on other microcontroller please contact sales office, they will evaluate your request.

Thank you very much for the clarification. I'm waiting for the STM32F303K8 to arrive and I will test it there too.

I am using the LSM9DS1 sensor which is produced by ST, I thought it's enough to be able to test the library.

The point b is a bit unclear, it looks like it's unfinished.
