    BHy1_driver_and_MCU_solution API, bhy_driver_init error

    Hello, I am rying to use the BHy1_driver_and_MCU_solution. I have followed the porting instructions and after I call bhy_driver_init() I get my error message. I tried printing the error code and -18 printed out. The thing is I don't see a #define statement in bhy.h defining -18.

    s8 bhy_err =0;
    bhy_err = bhy_driver_init(bhy_firmware_image);
    if(bhy_err!= BHY_SUCCESS)
    {
    printk("Fail to init bhy %d \n",bhy_err);
    }
    else{
    printk("initialized,waiting for interupt...\n");
    }

    do{
    (void)gpio_pin_read(bhi_int_pin,21,&p);
    }while(p);
    do{
    (void)gpio_pin_read(bhi_int_pin,21,&p);
    }while(!p);

    printk("entering while loop \n");

    What is also weird, is that the interupt pin also fires and the statement "entering while loop prints in my terminal".

    I believe I have implemented the I2C functions correctly, returning 0 for succes and a negative value in case of failure.

    Does anyone have any insight?

    For the error code is -18.

    we have a "BHY_INIT_RETRY_COUNT" to define retry times when download failed. default is 3.

    so error code is -6 actually. It means the CRC error.

    which fw you used? and what board you use?

    Thanks for the reply.

    I am using the BHI160BP even though it says BHI160B on the shuttle board. I tryed to upload Bosch_PCB_7183_di03_BMI160-7183_di03.2.1.11696_170103.fw and Bosch_PCB_7183_di03_BHI160BP_PDR_6DOF_8G-7183_di03.2.1.11696_r5.1.bin . I used the fw2header tool to convert to a .h file.

    What exactly does CRC error mean? Does it mean the I2C communication is bad?

    Hi Varou,

    BHI160BP is not a publicly available part. This forum is only for the support of publicly available part numbers. Please contact your Bosch Sensortec Field Application Engineer directly for support.

    Ok I will.

    However, what exactly does CRC error mean? Does it mean the I2C communication is bad?
