What's wrong with the gpio-buzzer?
I've got a ubuntu-based board with two buzzers. Among them, one is connected to gpio506 and the other gpio510.
According to notes left by previous developers, the commands to init the two gpio ports are as follows:
echo 506 /sys/class/gpio/export
echo out>/sys/class/gpio/gpio506/direction
echo 510 /sys/class/gpio/export
echo out>/sys/class/gpio/gpio510/direction
And the commands to turn them on/off are as follows:
echo 1 > /sys/class/gpio/gpio506/value ==> set buzzer on
echo 0 > /sys/class/gpio/gpio506/value ==> set buzzer off
echo 1 > /sys/class/gpio/gpio510/value ==> set buzzer on
echo 0 > /sys/class/gpio/gpio510/value ==> set buzzer off
H/W engineer checked them and found good. But the trouble is that only commands to turn buzzer 510 on/off works, 506 not working.
What's wrong with it? How can I check the fault inside the platform?
