BHI160 Reading FIFO hangs the i2c and makes the SCL Low forever

[Saicharan]

Hi, 

I am currently using Max78000 to interface with BHI160, I am using a 1.8 V supply to power the Sensor, and I am operating the system clock at 60MHz.
when I tried to use the read the FIFO, it gets into a hanging state( It makes my SCL to a Low state forever), I am currently using my i2c clock 400kHz. 

I have Disabled the I2C Clock stretching and tried but the result is the same, I am attaching pictures for reference.

The 1st picture is the captured hanging state in the Logic analyzer.

The 2nd picture is the code snippet where I am stuck.

I am using this link as a reference https://github.com/BoschSensortec/BHy1_driver_and_MCU_solution 

If needed more details, will be provided for solving the issue.

Thanks & Regards

Hi Saicharan,

You could refer attached example code on STM32 as it worked.

Thanks, BSTRobin

We managed to get it worked with some modifications done with I2C Driver.
