[Soekris] net4801 JP5 User I/O with gpioctl

[Ben Greenfield]

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

  Linux depends on an ACPI BIOS to provide configuration for the HPET. The

 Great news on the patch.
 
 
 What is the reason for not having ACPI ?
 

There is no use for it on the net6501. The BIOS implementation is a lot of work.

[Soekris] net5501 - CF and HDD

[Greg Armer]

Hey folks,

I'm having some trouble and couldn't find much info on the net regarding it, so 
I was wondering if any of you may have any ideas.

I have the net5501 with an 8GB Sandisk CF card and a WD1200BEVS 120GB SATA HDD 
running OpenBSD 4.8. The issue I'm having is that I cannot get both the CF card 
and the HDD working at the same time. The CF card is the primary boot device 
and will be read only, while the HDD will store log files and other data that 
is written to frequently.

comBIOS detects both devices without any trouble...

however OpenBSD does not detect both devices during the remainder of the boot:
