BHI160B firmware upload not working

[tomlogevans]

Hello,
I am trying to use the BHI160B IMU device. I want to use its accelerometer and gyroscope features.

I am using the C driver code from https://github.com/boschsensortec/BHy1_driver_and_MCU_solution/. I have it connected to an STM32 microcontroller via I2C. I have managed to get the I2C comms working. I can successfully read the product ID as 131, and the revision ID as 3.

I want to use it in standalone mode, just to access the accelerometer and gyroscope. I don't have any external sensors connected on the sensor I2C interface.

I guess that the "BHI160\examples\accelerometer_remapping_example.c" is a good template to copy. I am confused about whether I need to upload a firmware file for the RAM patch. If so, I don't know which firmware to use. I have tried uploading "Bosch_PCB_7183_di01_BMI160-7183_di01.2.1.10836_170103.h", but this yields an error "BHY_RAMPATCH_NOT_MATCH". I have tried "Bosch_PCB_7183_di03_BMI160_BMM150-7183_di03.2.1.11696_170103.h", which yields an error "BHY_CRC_ERROR".

Hi tomlogevans,

Thanks for your inquiry.
I upload BHI160 example code on STM32F4 for your reference, please refer to the following code comments, including the correct firmware file.
#include "Bosch_PCB_7183_di03_BMI160-7183_di03.2.1.11696_170103.h"//For BHI160B IMU only
#include "Bosch_PCB_7183_di01_BMI160-7183_di01.2.1.10836_170103.h"//For BHI160 IMU only
