What is the use of this INT_SOURCE and INT_MAP register in ADXL345.
This INT_SOURCE register have different Bits for different types of Interrupt.
These Interrupts are
1)  Data Ready
2)  Single Tap
3) Double Tap
4) Activity
5) Inactivity
6) Free Fall
7) watermark
8) overrun

These bits will set by the device based on the requirements. In Driver ISR routine we are reading this Register to
check which bit is set based on the interrupt bit we will forward the request to the corresponding routine to handle the functionality.

I have already verified this device in OMAP4460 and in OMAP4460 interrupts are generated properly and each functionality was working fine.
When i was trying to port this device in BBB i am not seeing any interrupt except watermark.

As  i told i connected ADXL345 externally to BBB pin header using Breadboard. There is no physical mapping of INT1 and INT2 pin with Interrupt controller.

Could you suggest any input on this

Thanks
Prakash

Fred:
It's odd that you have the code from chapter 2 working, but not the code
in chapter 6. How is the LED wired to P9_11?
Did you config-pin P9_11 for gpio and not pruout? Is P9_11 configgid ...more

Oh, sorry, my bad. It was related with the pin's configurations.
Can you tell me what's the difference between using the OCP interface or
usual PRU interface? Both allow to controlling the pins at ...more
