Can you describe a step-by-step procedure that someone else can
follow, that will show the problem occurring?

Yes, 2.5.3.
I duplicated the issue again today.

Also I noticed on the help/about page, there is not an entry for copywrite
for 2013 (and 2014), so you may want to update that with the next release.

My bad.  Thank you for the reference AND the gentle reminder that the

Making me provide references, eh?  Well, OK:

https://www.kernel.org/doc/Documentation/gpio/gpio-legacy.txt

...scroll down to "Paths in Sysfs" where you will find:

/sys/class/gpio/gpioN/

"direction" ... reads as either "in" or "out".  This value may
normally be written.  Writing as "out" defaults to
initializing the value as low.  To ensure glitch free
operation, values "low" and "high" may be written to
configure the GPIO as an output with that initial value.

Note that this attribute *will not exist* if the kernel
doesn't support changing the direction of a GPIO, or
it was exported by kernel code that didn't explicitly
allow userspace to reconfigure this GPIO's direction.

Charles, I didn't see any reference to 'high' being a valid 'direction' 
using the virtual GPIO pins, so I added these to the end of the setup.sh 
file.  If I get time later today or tomorrow, I'll update the script to 
process an optional 'level' parameter to the pin list rather than 
hardcoding it like this.

Re: [Emc-users] Beaglebone linuxcnc error loading after trying other GUI

[Charles Steinkuehler]

It looks like you're a member of the xenomai group.  The other piece of
the puzzle is telling the kernel which gid is used for xenomai, which
happens towards the end of etc/rc.local:

echo 999 > /sys/module/xeno_nucleus/parameters/xenomai_gid

See what's currently in the xenomai_gid file via:

cat /sys/module/xeno_nucleus/parameters/xenomai_gid

...if it's not 999, that's your problem.  If it is, something is very
confused.  Have you tried logging off and back on and/or rebooting?

One possible source of trouble is the device tree overlays.  There is
currently no way to unload a device tree overlay once loaded, and the
different configurations use different overlays.  If that's your issue,
you _will_ have to reboot (it's the only safe way to remove an overlay),
but typically the errors generated from overlay problems are not related
to xemonai.

Isn't that the error you see if the OS has loaded its own parport driver?  
lsmod might show that, in which case a "sudo modprobe -r parport" might be 
in order.

If you type "id" at the command line you will get a string of
information about your user.
You would want to see "xenomai" listed as one of the "groups"

[Emc-users] Beaglebone linuxcnc error loading after trying other GUI

[Josiah Morgan]

I posted this a little bit ago but decided to repost adding some helpful
info.
I had my beaglebone-linuxcnc system running smoothly until yesterday it
just completely decided to stop working.
I just realized the series of events that caused it to stop working.
I wanted to see what it would look like loading other GUI's instead of axis.
I may have even tried using the touchy gui.
could this have messed up settings inside of the linuxcnc build that is
keeping it from loading linuxcnc anymore even with the gui set back to axis?

this is what I get when I try to load linuxcnc now.  I have tried loading
all the different ini file configurations to see if anything works and
everything gives me the same error now.

You can fix this by editing the setup*.sh script in your configuration
directory.  At the end of the file is a list of GPIO pins (using the
Linux Kernel numbering scheme) and their desired mode (typically out).

The default initial value for output pins is low.  If you replace the
"out" in setup*.sh with "high" for the appropriate pins, the GPIO pin
will be initialized to a high value which it will keep until LinuxCNC
fully starts up and begins to twiddle the pins.  If you need to figure
out the proper kernel GPIO values to change, you may find the following
spreadsheet useful:

testing the code to make sure it works as expected.

OK, here's the quick and dirty version of the PRU code that just inverts
the step signal.  I've verified it moves motors on my 3D printer and the
default step state is high (the step pulse is a falling edge, followed
very briefly by a return to the default high state).

Just drop it in the linuxcnc/xenomai directory and adjust your ini/hal
file to load the new file (pru_generic_fall.bin).  The debugging files
are included just in case you feel _really_ adventurous!  :)

cc'd directly to the two interested parties in case the list strips the
attachment.  If it does, and someone else is interested in a copy of
this as well, just e-mail me directly.

WARNING:  This is for short-term use ONLY!  I expect to have updated
code that will support setting the step polarity via HAL within a week
or two, along with many other changes that will require significant
modification to any existing configurations (but will make pin numbering
a whole lot more consistent and understandable!).

Charles, sorry it took so long to get back to you on this, apparently 
others found 'better' uses of my time ;-)


The driver works as advertised!  I've attached two scope traces, one 
taken with the original driver (Y_Step_Pos.png) and the second 
(Y_Step_Neg.png) taken with the new driver.  The only oddity, which 
doesn't affect the motion but does affect power consumption, is that the 
signals are not initialized to high (AKA inactive state) on program 
startup.  The signals do go high and remain there after the first step, 
however.  The motors are energized at high level when the signal is left 
low.


Thank you for building this!  I'll use this until your new, improved, 
version is available.

I'm no expert in the Xenomai flavor of LinuxCNC, but I think the key
part of that error message is "cannot determine if this user is a member
of group xenomai".  Did you add yourself to the xenomai group, log out,
and log back in?

Wow, that is a dangerous bug!

By "latest stable version", do you mean 2.5.3?  Or v2.5.3-91-g5751b1d or

I ran into this yesterday as well.
I edited the ngc file to remove 4 spot drill operations at the start of the
program, saved it, reloaded it (saw that the operations were gone in the
gui), ran the program, and it started with the spot drill points I removed
from the file.  stopped the program, re-started it, and it ran as expected.
I didn't think much of it at the time.

What I mean is that if any of the GPIO pins you are using have sserial as a 
secondary function, it must be specifically disabled in the sserial config 
string or the GPIO bit will toggle during device probe

Yes, I am using DB25 port for sserial to two 8i20's and encoders and IDC 
port for IO.

What configuration and which pins are you using? (I do know sserial must be 
specifically disabled in the config line to prevent I/O twiddling at startup)

I think that this line is what you are looking for. As Kirk mentioned, it
just did not find PPMC board on particular LPT port.

Re: [Emc-users] The d525 performance tweak

[Marius Alksnys]

Yes, Gigabyte GA-E350N is a good option.
http://uk.gigabyte.com/search/search.aspx?kw=GA-E350N#pr-1

Their performance is better than Intel d525, latency is good. I am using 
number of them on different setups. I tweak their RAM frequency to 1333 
MHz with 1333 RAM.

It is possible to achieve low latency by changing settings in BIOS or 
even better - by disabling unnecessary functions like audio, usb, lan, 
ports.

GA-E350N and GA-E350N WIN8 are the same. Don't know about USB3 version..

BTW, I was writing about this MB as an option and then your reply came 
out :)

Re: [Emc-users] Hostmot2, MESA 5i25: pins toggle on startup

[Marius Alksnys]

I am sure it is so - they are active low. These boards are simple 
opto-isolators with 817. Their "+" inputs are connected to +5V and "-" 
to MESA IO pins.
There are LED indicators on each of those channels. And they blink at 
LinuxCNC startup for part of a second.
I didn't try is_opendrain option yet..

Re: [Emc-users] The d525 performance tweak

[Dave Cole]

Good information..

Intel has stopped making most motherboards now, which is apparently 
ahead of schedule from what they originally announced and the D525MW 
which last came out in a D525MWE edition (Extended) seems to no longer 
be available except what is left in stock.

Is the Gigabyte 350 MITX board a good substitute?
NewEgg has it for $69 : 
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128597

Also, apparently there is a Chinese company making a D525MW clone now or 
is the board USED as it states..  the add is a little confusing.

Actually, I think the this error message:

insmod: error inserting
'/usr/realtime-2.6.32-122-rtai/modules/emc2/hal_ppmc.ko': -1 Operation not
permitted

indicates that the Pico-Systems PPMC card was not found, so the module 
wasn't loaded. The card may not have power or is damaged. If you have 
verified that you have power to the board, Pico-Systems has a 
diagnostics utility that may help from there.

Found another source of the XML, in cmorley's sticky thread:
http://www.linuxcnc.org/index.php/english/forum/39-pncconf/21670-5i25-firmware-xml-files-for-pncconf#32198
With this zip file it actually worked.

no, master is required - that is the remapping work which has been lingering in

Re: [Emc-users] The d525 performance tweak

[Sven Wesley]

RTAI works better on some boards with the boot option isolcpus=x set in
Grub, where x is the number of processor cores minus the first one. In the
case of the d525, which has two cores, it should be isolcpus=1. On a four
core CPU this will be isolcpus=1,2,3 (specially with hyper threading
active, which doesn't make sense on an isolated two core CPU).
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RealTime
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?The_Isolcpus_Boot_Parameter_And_GRUB2

I did it this way:
$ sudo gedit /etc/default/grub
Add the isolcpus option in the end of the line GRUB_CMDLINE_LINUX_DEFAULT
Save and exit
$ sudo update-grub
This is one of the rare cases of a needed reboot, so reboot.

You can run the command
$ cat /proc/cmdline
afterwards to make sure that it took effect. it should be included in the
output.
