Hello
please excuse my bad english
I have a problem to control the gpio pins on the carambola board
all connections working fine (serial,eth)
I can turn on & off the gpio pins with the console and
gpioctl but I tried to write a shell script and thats the problem
and google -> too many results to distinguish

#!/bin/sh

P1=1
P2=2

setup() {
# set GPIO1+2 as output
gpioctl dirout $P1
gpioctl dirout $P2
}


so it looks like this this is not the complete code but I have tried many changes
nothing work
so where I need to save the script ? ( I have saved a gpio.sh in /etc with win scp)
is it necessary to change chmod to 755 ?
what should I do to make the script available at startup/boot

I want to switch 2 relays on and off ...actually simple but not for a beginner...

First of all, you don't put generic scripts in /etc
Under /etc/init.d are boot up scripts that have a special header (google Linux init Scripts) and only have the purpose of running and stopping programms at a specific point in the boot process (google Linux runlevels).
If you put an executable under /bin, /usr/bin, /sbin or /usr/sbin it will be available as a console command.

Secondly, your Script doesn't do anything except define a method named "setup" ... nowhere in your script is it executed... (google Linux shell scripting tutorial)

And yes, if you want to execute a script directly it needs to be set as executable with chmod.

put your script in /etc/rc.local

rc.local is run after all the script found in /etc/rc.d (after S99sysctl)
