Hi Robert,
I did mapping the INT1 pin one of the GPIO pin of the BBB now it is working
fine.ISR is called and i am able to collect the
X,Y,Z axis data from device.

Hello Marek,
to be honest, I really don't remember if it was succesfull.
For sure I can tell you that we didn't got any bricked boards... so at
least the board with 1G ram was working anyway (maybe using only 512M as
the original configuration).
It's also possilbe that the BBBs auto recognized
Hi,
do you remember by any chance which RAM chips was used? Thanks.
BR,

You'd have to read the data sheet of the sensor to know if it can work that
way. Most of the time the interrupt pins need to actually be connected to
the processor somehow to work. I'd suggest that you connect them to gpios,
configure the BB gpio pins as interrupts, and check the data sheet to see
Hi Jim,
My driver is implemented based on the Interrupt not poll based so i
configured one of the GPIO pin for interrupt.
Could you please tell me what is the use of these two interrupt pin INT1
and INT2 given for the device.
As per my understanding i can use these device in poll based without
I have made progress on this and have a .dtbo that I can load manually and
set all of my gpio in the desired state I am looking for.
My issue now is getting this overlay to load on boot. Here is my uEnv.txt:
uname_r=4.4.113-ti-r149
enable_uboot_overlays=1

I'd check out the data sheet. Page 20 covers an overview of the interrupt
configuration. I guess you can use either one, depending on how you set the
registers.
You can poll that sensor all day long. But if you want to use the
interrupts, you have to connect the pins, at least one of them, and
