[beagleboard] Re: no data from /dev/input/event1

I tried a clean reboot. Now event writes events from /dev/input/event1 to stdout. Too many actually. In any case, my original issue seems resolved by a reboot. On Tuesday, March 28, 2017 at 11:53:34 AM UTC-4, John Franey wrote: > > Hi, > > I am experimenting with gpio_keys driver, to see if

[beagleboard] Detecting state of GPIO pins during boot up

Hi folks I hope that I am posting to the correct group apologies if this is the wrong place. We are creating a system based on the beagleboard black. We would like to implement a "Factory Reset". i.e. if I hold down a switch for a long period of time, say around 10 seconds, then we want to

[beagleboard] Custom device overlay or cape-universal - decisions...

Hi everyone, I'm building a custom piece of mechatronics as part of my day job. We have a custom interface cape laid out (it doesn't have an eeprom) and I've mapped out the 16 lines we need to go back to the BBB. I've written a custom device tree for these lines which compiles with dtc fine,

[beagleboard] no data from /dev/input/event1

Hi, I am experimenting with gpio_keys driver, to see if I can get it to work. I fail. Any suggestions? I can read the value of the gpio through /sys/class/gpio/cpio48/value, and the value in fact changes depending on the button pressed/released. The trouble: NOTHING comes up through
