Hello,
i want to control the onboard buzzer of a nsa320 , maybe by echoing stuff into a file under /sys/class/whatever.
the purpose is to have an audible feedback in the event of a major malfunction(like overtemperature , fan failure, smartctl etc.)

By googling "nsa320 buzzer", i found in this post

http://lxr.free-electrons.com/source/arch/arm/boot/dts/kirkwood-nsa320.dts

on line 110 that there is a compatibility issue between driver and hardware.
Does this apply to the current latest kernel too?

if not, what do i have to echo to which file to switch on/off the beeper?

Dirk,

Try this to see if you can turn it on and off:

/bin/echo 44 > /sys/class/gpio/export
/bin/echo "out" > /sys/class/gpio/gpio44/direction
/bin/echo 1 > /sys/class/gpio/gpio44/value
/bin/echo 0 > /sys/class/gpio/gpio44/value

Hello.

Any update about this?

I do

/bin/echo 1 > /sys/class/gpio/gpio44/value
/bin/echo 0 > /sys/class/gpio/gpio44/value

and I can ear the buzzer connecting and disconnecting (a little click in the buzzer) but "beep" command doesn't works

Thanks
