hal-core

Hi Grotius,

Have you been able to use the loadusr command within your hal version?
I have tried a few different ways and it seems to not be passing the information to run the program and give this error
halcmd: <stdin>:1: execv(): No such file or directory

I believe in the execv() it should display the name/path of what I am trying to run. I have tried placing the program in the bin directory and also using the full path when passing the name, but nothing seems to work

 

Hi Dave,

I did not use that, but there are a few hits if you paste this in the browser:
github.com/grotius-cnc/hal-core/search?q=loadusr
I did a short overview. I think it will not work.

What do you want to load? a Program? And when should it be loaded?
In the hal-core component folder, skynet example. First it load's a rt-halmodule (golden ring). This halmodule then loads a qt app
in (userland).
 

Hi Grotius,

I am trying to load the xhc-whb04b-6 components to use for my wireless pendant, I will take a look at that search

Hi Dave,

Ok. If you pass me the link of the "xhc-whb04b-6" source code, i will try it for you.

Maybe do the Very Verbose output:
./halcmd -V loadusr ..

If you look at the lcec_conf file. This is also a loadusr file. I used a unix command to load this file :
# Unix command to load the ethercat .xml config
/opt/hal-core/rtlib/./lcec_conf /opt/hal-core/rtlib/ethercat-conf.xml &

Hi Grotius,

Here is the source to that module
github.com/LinuxCNC/linuxcnc/tree/master...r_comps/xhc-whb04b-6

I am also unable to use the mesa ethernet module, I can load the hostmot2 without issue, but I can't use the hm2_eth due to looks like some kind of permissions issue?
 

Did you edit and perform the runtest file of the hm2_eth file?
~/opt/hal-core/src/hal/components/hm2_eth/./runtest

I can not test it myself, i have no mesa. image missing /media/kunena/emoticons/sad.png

The "could not fetch" warning is a warning outside of hal-core. I think pcw know's what's going on here.
the /usr/sbin/iptables is a root dir.
See hm2_eth.c line 464
