unittest failing #5

Closed jbodart closed 5 years ago

jbodart commented 5 years ago

When I try to run "make unittest", i get a "chmod: cannot access '/dev/ccat_*': no such file or directory. I am not sure of what it means. I get no complain at make/make install

pbruenn commented 5 years ago

The error indicates there are no device files created for ccat devices. On which hardware do you run this? What output do you get in dmesg , when you run make install?

jbodart commented 5 years ago

Nothing in dmesg during make install. hardware CX5140, running ubuntu server 18.04 with RT kernel 4.9.115.

It seems I have 3 ethernets port recognized (w or wo ccat).

Oh yes of course, the problem is "ec_bhf". See this answer: https://github.com/Beckhoff/CCAT/issues/3#issuecomment-266788708

aaahhhhh. I feel so bad. I did not look at the issues as I saw 0 open issues. Indeed that was the problem. That solves the problem with my ethercat master (KPA) as well

No problem, it took me a while to remember, too ;-)
