    BNO055 firmware preloaded?

    BNO055 firmware preloaded?

    Hi,

    Does the BNO055 come with preloaded firmware that is internally stored and automatically loaded by the bootloader?  I just want to make sure that I will not need to load any firmware to the device before I can use it.

    Also, there is a section in the datasheet that talks about possible firmware updates. If there is a firmware update and I want to update my device, what pins do I need to be able to control? I will be using in I2C mode so SDA, SCL, nboot_load_pin? Do I need bl_ind (pin 10) or any others?

    Thank you.

    The BNO055 has Firmware which is already loaded into the chip so you can directly use it without downloading the firmware again.

    To update the firmware of BNO055, you need to connect nBOOT_LOAD_PIN (pin 4), reset pin (pin 11) and protocal pin which you already conencted.
