I am toggling the input into a GPIO line on my BeagleBone from high to low
every 500 ms using an Atmel uC. I have registered a handler for this in my
Linux Kernel Module, but the handler is not being called for some reason.
My module code is -
#define GPIO 54
#define GPIO_INT_NAME gpio_int
Does the problem have something to do with dev id paramter in the interrupt
handler?

Hi Stephen,
I am too facing the same issue when connect to beaglebone using putty. I
tried the the solution you mentioned but it is not working for me. Either
the file is not getting deleted or there is some other issue. I am using

Thanks, that helps! The documentation says that a toplevel window has a

Hi,
I'm building a project with a beaglebone black for which I need an i2C
channel. Since I need address 0x56 I need to use i2c1(i2c-2) because
i2c2(i2c-1) blocks certain addresses for the capes. I've found this command
to activate it:

First I must say that I have no hands on with the Beagleboard C3, so i can

Yes, you can write a boot init script, or service to do this for you. You
did however forget to mention which distro you're using, and which init
daemon is running on that distro.
pstree should list the init daemon at the first node.

Does this mean you're using a beaglebone white ? The error message can be
related to a couple things. One of which could be due to using the wrong

As far as I know you have to be in the priviledged mode to change mux value
of pins (or you can use PRU to do this) which means
you have to write kernel module like this (
