[Emc-users] BBB - hal input pin setup
I was reading the tutorial/explanation
(http://bb-lcnc.blogspot.com/2013/07/adding-homelimit-switches.html) for BBB
hal setup and i tried to test it myself. I wrote a simple hal file to test the
gpio input and output. I used the p8.7 as input and p8.11 and p8.13 as output:
loadrt hal_bb_gpioinput_pins=103 output_pins=111,113
net gpiopulse siggen.1.clock = bb_gpio.p8.out-11 bb_gpio.p8.out-13
#net intoout bb_gpio.p8.in-3 = bb_gpio.p8.out-13
This works fine, i can see the leds blinking. There are also no errors about
the pin 103 usage - strange.
But if i change the input_pin103 to 107, i get an error:
Waiting for component 'hal_bb_gpio' to become
ready..
ledtets.hal:11: /home/linuxcnc/linuxcnc/bin/rtapi_app exited without becoming
ready
ledtets.hal:11: insmod failed, returned -1
If try to use the 103 again and net intoout bb_gpio.p8.in-3 =
bb_gpio.p8.out-13
I get a different error: ledtets.hal:31: Pin 'bb_gpio.p8.in-3' does not exist
I have no idea what could be wrong. Can some please give me a hint for an
error. Any suggestion would be greatly appreciated.

I further think that I have made this go away by following Seb's advice from a while ago: cd debian ./configure -r cd .. dpkg-checkbuilddeps Then sudo apt-get install that list. (after editing it, as it contains a few comments like versions numbers and alternative packages, Hello Andy Thanks for the hint. I used the following command to pull in all the dependencies: sudo apt-get install libpth-dev dvipng tcl8.4-dev tk8.4-dev bwidget blt asciidoc source-highlight dblatex groff python-tk libglu1-mesa-dev mesa-common-dev libosmesa6-dev libgtk2.0-dev libgnomeprintui2.2-dev libgnomeprintui2.2-dev texlive-lang-cyrillic But make dos not like me :-( thomas@Intel64:~/Projects/linuxcnc/src$ make Makefile:87: Makefile.inc: No such file or directory Makefile:98: *** Makefile.inc must specify 'BUILD_THREAD_FLAVORS' and other variables. Stop. thomas@Intel64:~/Projects/linuxcnc/src$ Any help? this indicates Makefile.inc does not exist, which is created by a successful configure run. Since the first attempt failed configure didnt complete.

Re: [Emc-users] BBB - hal input pin setup
The bb_gpio.p8.in-** are always two digit numbers, so bb_gpio.p8.in-03
should work.
The without becoming ready is probably indicating that the gpio pin isn't
correctly configured elsewhere, like the dts file. Did you compile the dts
file after editing (that was one of the first things I had to learn about)?
sudo ./dtc.sh should do the trick. I think your dts file looks good for
using pin 7.
In the setup.sh file, I think 36 should be changed to 66 for using pin 7.

I was reading the tutorial/explanation (
http://bb-lcnc.blogspot.com/2013/07/adding-homelimit-switches.html) for
BBB hal setup and i tried to test it myself. I wrote a simple hal file to
test the gpio input and output. I used the p8.7 as input and p8.11 and
p8.13 as output:
loadrt hal_bb_gpioinput_pins=103 output_pins=111,113
net gpiopulse siggen.1.clock = bb_gpio.p8.out-11 bb_gpio.p8.out-13
#net intoout bb_gpio.p8.in-3 = bb_gpio.p8.out-13
This works fine, i can see the leds blinking. There are also no errors
about the pin 103 usage - strange.
But if i change the input_pin103 to 107, i get an error:
Waiting for component 'hal_bb_gpio' to become
ready..
ledtets.hal:11: /home/linuxcnc/linuxcnc/bin/rtapi_app exited without
becoming ready
ledtets.hal:11: insmod failed, returned -1
If try to use the 103 again and net intoout bb_gpio.p8.in-3 =
bb_gpio.p8.out-13
I get a different error: ledtets.hal:31: Pin 'bb_gpio.p8.in-3' does not
exist
I have no idea what could be wrong. Can some please give me a hint for an
error. Any suggestion would be greatly appreciated.
