many thanks, I will try.
by the way I said about raspi 1

This phenomenon was stopped when I connected lan cable.
I don’t know the reason.
I looked the source code and I guess for raspi 1:
Plan9 BCM pin
GPIO0 17 11
GPIO1 18 12
GPIO2 27 13
GPIO3 22 15
GPIO4 23 16
GPIO5 24 18
GPIO6 25 18
GPIO7 4 7
GPIO8 28 24
GPIO9 29 21
GPIO10 30 ?
GPIO11 31 ?
SDA 2 3
SCL 3 5
CE1 7 26
CE0 8 24
MISO 9 21
MOSI 10 19
SCLK 11 23
TxD 14 8
RxD 15 10
and I tried some experiments.
(a) turn led light on/off that is connected to GPIO0 pin
term% echo function out GPIO0 >ctl
term% echo 1 > GPIO0
term% echo 0 > GPIO0
term%
the result is OK.
(b) read GPIO1 status
term% echo function in GPIO1 >ctl
I expected:
term% cat GPIO1 # low voltage
0
term%
however I have:
term% cat GPIO1 # low voltage
000000...
I expected:
term% cat GPIO1 # high voltage
1
term%
however I have:
term% cat GPIO1
111111...
is this a feature or bug?
