Hi, AGL
Hello Ouyang,
I am new member in AGL. Recently I try to use signal-composer connect to low-can, then I use the etc/control-basic-conf.json, copy control-basic-conf.json to control-signal-composer.json, then do command
“systemctl start afm-service-signal-composer--7.0--main@0.service<mailto:afm-service-signal-composer--7.0--main@0.service>”, but failed, there have some error that I don’t know how to fix it.
Welcome to AGL.
((side note, the "mailto:"; inserted in your message are probably
artifacts of your mail agent (or mine???), so I ignore it))
The log shows that a segmentation fault occurs during the initialisation
of the binding signal-composer. The fault is catched by the binder that
consequently stops its execution.
The reason why the signal-composer crashes is not known. An open JIRA
ticket matching your problem exists:
https://jira.automotivelinux.org/browse/SPEC-2312
Can you add your report there?
Best regards
José Bollo
