Hi,

    Pin Configuration of ADXL345

    ----------------------------------------

    ADXL345                                    BBB P9 HEader

    -------------                                    ---------------------

    SCL ----------------------------------->  19 pin  (I2C2_SCL)

    SDA ----------------------------------->  20 pin    (I2C2_SDA)

    GND ----------------------------------->  01 pin   (DGND)

    VCC ----------------------------------->   03 pin  (VDD_3V3)

    SDO ----------------------------------->   02 pin  (DGND)

    CS    ----------------------------------->   04 pin (VDD_3V3)

    I followed the same pin configuration to interface ADXL345 in BeagleBone Black but with these pin configuration the device is not detected in u-boot.

    I was facing issue while running I2C commands under u-boot related to "padding configuration not enabled."

Could someone please help me out of these issues.

Thanks

Prakash
