It's telling you that the error is in line 54 of the file drv_audio_pdm.c - so have you looked at that line for an obvious divide-by-zero ?

Hi.

I asked if you did the prerequisitions listed on GitHub before you installed?

Did you do the following:
    
1) Install Git v2.xx.xx, Available from https://git-scm.com/. Use default configurations.

2) Install GNU ARM embedded toolchain v4.9-2015q3. Available from launchpad.net/.../4.9-2015-q3-update. Use default configurations.
    
3) Install Make must and put in the system path. For example gnuwin32.sourceforge.net/.../make.htm.
 
4) Create a user at https://www.invensense.com/. Under "Downloads" download "Embedded MotionDriver 6.12". Unzip the downloaded motion_driver_6.12 folder and navigate to motion_driver_6.12/mpl libraries/arm/Keil. Unzip the folder libmpllib_Keil_M4FP.zip. Copy the extracted library libmpllib.lib into <your Thingy folder>/libs/libmpllib_Keil_M4FP/. Finally, unzip /motion_driver_6.12/mpl libraries/arm/gcc4.9.3/liblibmplmpu_m4_hardfp.zip and copy the extracted library liblibmplmpu.a into the folder <your Thingy folder>/libs/liblibmplmpu_m4_hardfp/.


You should run setup_sdk.bat after you did point 1, 2, 3, and 4.

If it's still not working, can you please upload a zip file of your project?
