can someone please tell me whether i am following the right procedure or
not.if the procedure is correct then ca someone please tell me why
interrupt is not generating.
if the procedure is not correct then can someone please help me on this to
how to generate interrupt in ADXL345 device.

For me device pin mapping is done using breddboard to P-9 header of the
Beaglebone Black.
I am able to detect the device but while rotating the device i am not
getting the X,Y,Z co-ordinate.
Even register update also not happening.
I am trying to read the DATA_READY bit of INT_SOURCE register inside the
ISR routine to collect the data of X,Y,Z axis but ISR routine is not
calling.
For ISR should run is it required to map INT1 or INT2 pin of ADXL345 from
breadboard to any of the pin of the P-9 header so that CPU will get
notified and call the device ISR for run.
Can someone please help me on this.
