Hey All, I have a net4801running what I think is a highly modified OpenBSD 3.6. I'm trying to use the gpioctl and although it appears to work on the command line I can see no evidence of it working with my multi-meter.
I have done a lot of looking at this topic on the internet and I found various discussions on using gpioctl and some recommendations about configuring the pins prior to entering the secure level 1. My systems happens to have an /etc/rc.securelevel mine looks like this. # cat /etc/rc.securelevel # $FabBSD$ # $OpenBSD: rc.securelevel,v 1.16 2004/07/06 04:05:03 deraadt Exp $ # # site-specific startup actions, daemons, and other things which # can be done BEFORE your system goes into securemode. For actions # which should be done AFTER your system has gone into securemode # please see /etc/rc.local # This is the desired security level securelevel=1 echo -n 'starting pre-securelevel daemons:' # # Place local actions here. # /usr/sbin/gpioctl -c 01 out; /usr/sbin/gpioctl -c 03 out; echo '.' The boot process produces this output which makes me think it is working: starting pre-securelevel daemons:pin 1: caps: in out, flags: -> out pin 3: caps: in out, flags: -> out . setting kernel security level: kern.securelevel: 0 -> 1 Finally I think it is not working because I expect this command: # gpioctl -d /dev/gpio0 1 0 to make either pin 1 or pin4 of JP5 low or zero voltage. I also expect it to hold that value until I change it with another command. here is a transcript of me interrogating JP5 pins. # gpioctl -d /dev/gpio0 1 pin 1: state 1 # gpioctl -d /dev/gpio0 1 0 pin 1: state 0 -> 0 # gpioctl -d /dev/gpio0 1 pin 1: state 1 # gpioctl -d /dev/gpio0 3 pin 3: state 1 # gpioctl -d /dev/gpio0 3 0 pin 3: state 0 -> 0 # gpioctl -d /dev/gpio0 3 pin 3: state 1 Interactively I can manually create the ports which also doesn't work. Here is a transcript: # gpioctl -d /dev/gpio0 -c 01 out pin 1: caps: in out, flags: out -> out # gpioctl -d /dev/gpio0 1 pin 1: state 1 # gpioctl -d /dev/gpio0 1 0 pin 1: state 0 -> 0 # gpioctl -d /dev/gpio0 1 pin 1: state 1 Finally the verison of gpioctl doesn't support pp in fact it only seems to support in and out as flags. # gpioctl -d /dev/gpio0 -c 01 pp gpioctl: GPIOPINCTL: Operation not supported by device I know I'm not helping myself by using some strange BSD variant but I have heard it works. I would like any guidance on how to further investigate the issue. My next step will probably be to go to netbsd and see if I can get the custom software I need off the old machine. Any ideas welcome. Ben _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
