Hi,
I am looking at the headset stuff.
The detection is at gpio492 on gta04a5 if I
understand everything right.
I exported that and no reaction there on plugging
And then I am wondering:
root at gta04:/sys/class/gpio/gpio492# twl-i2c.sh GPIO r 0x13
0x00
# twl-i2c.sh GPIO r 0x14
0x00
No pullups/downs enabled?!
Hmm, floating inputs there?!
twl-i2c.sh GPIO w 0x13 0x20
does the trick. the exported gpio shows values. But are the pullup/down
values correct there?
Regards,
Andreas
