Antw:eBus Schaltung Rpi in Betrieb nehmen!
« Antwort #45 am: 21 März 2018, 21:55:31 »
Ich habe die von jkyprian vorgeschlagenen Änderungen in den Source vom ttyebus übernommen. Somit sollte es nach einem Buffer Overflow nicht mehr zu einem Deadlock kommen.

Der ttyebus läuft jetzt bei mir seit 3 Tagen ohne Probleme. Allerdings erhalte ich immer noch Buffer Overruns:

Das ist jetzt eigentlich nicht weiter schlimm. Ich wüsste nur trotzdem ganz gerne woran das liegt. Im ebusd.log finden sich komischerweise keine Fehlermeldungen zu den Zeiten wo der Buffer overrun auftritt (was mich wiederum etwas wundert!? Es werden ja immerhin Daten verworfen). Gelegentlich kommt es zu einem bus error oder zu einem broadcast receive Fehler wie z.B.:

Das entspricht 23/4944=0.47% Errors pro Stunde. Ich vermute mal das ist durchaus normal?

Gibt es vielleicht Operationen (z.B. auf der SD-Karte aufräumen) die irgendwie die Linux Kernel und andere Prozesse blockieren?

Der ttyebus läuft jetzt bei mir seit 3 Tagen ohne Probleme. Allerdings erhalte ich immer noch Buffer Overruns:

Mit RX_BUFF_SIZE = 256 gibt es auch bei mir keine Buffer Overruns mehr.

Zitat
Mit RX_BUFF_SIZE = 256 gibt es auch bei mir keine Buffer Overruns mehr.
Da es sich bei Linux einmal primär um kein Echtzeit Betriebssystem handelt, kann ich mir schon vorstellen, dass ein anderer Prozess wegen seiner höheren Priorität
den ebusd eine Zeit lang blockiert und deswegen der Buffer nicht ausgelesen werden kann.
Hast du noch etwas anderes auf dem Raspi laufen? Bzw. hast du einmal versucht, den Raspi neu aufzusetzen und nur den ebusd zu installieren? Das könnte diesen Verdacht erhärten.
Ich werde den Buffer im ttyebus halt noch einmal vergrößern, das tut ja nicht weh, aber die Frage ist natürlich: wo ist Schluß ? Da der ttyebus direkt im Interrupt läuft entgeht ihm nichts, also kann es letztlich
immer zu einem Overrun kommen wenn die Daten nicht zeitgerecht abgeholt werden...

Auf meinem Raspi laufen noch einige andere Dienste (influxdb, chronograph, mosquitto, openhab2). Das ebusd ausgebremst wird kann also durchaus sein. Aber das müsste sich doch mit geeigneten Einstellungen vielleicht in den Griff bekommen lassen. Ich habe jetzt mal "Nice=-10" für ebusd gesetzt und die Buffergröße wieder auf 64.

Bei den verschiedenen Optionen wie nice, io priority, rtprio, etc blicke ich noch nicht so richtig durch. Hinweise und Tipp sind also sehr willkommen ;)

Overrun tritt bei nice=-50 und Buffergröße 64 leider immer noch auf. Das gleiche bei
CPUSchedulingPolicy=rr
CPUSchedulingPriority=50
IOSchedulingClass=realtime
IOSchedulingPriority=0
und einer Buffergröße von 64.

CPUSchedulingPolicy=rr und Buffergröße 128 läuft jetzt seit 10 Stunden ohne Overrun. Ich werde das mal das Wochenende über beobachten.

hi, I followed all the instructions of galileo on my raspberry 2 with wheezy raspbian.
now I see the /dev/ttyebus device, but if I trying to use with ebusd I obtain no traffic:

root@rasprino:~# ebusd -f -d /dev/ttyebus --lograwdata=bytes

instead if I use /dev/ttyAMA0 (which does not disappear, even if is not in use) I see ack packets:

Hello modenet!

I think you have a Problem with the configuration files!
There are 2 installation methods:

Method 1: (you can read in  John's github)
git clone https://github.com/john30/ebusd-configuration.git
if [ -d /etc/ebusd ]; then sudo mv /etc/ebusd /etc/ebusd.old; fi
sudo ln -s $PWD/ebusd-configuration/ebusd-2.1.x/de /etc/ebusd


Method 2:
You can also install from here, but these files are a bit older.

Hallo

nachdem ich endlich dazu gekommen bin den Rpi Bausatz zu löten, möchte ich das Projekt weiter mit meinen minderen Linuxkenntnissen voran treiben.

Ich habe soweit alles "installiert". Starte ich den ebusd Service steht im ebusd.log leider nur
[bus error] unable to open /dev/ttyUSB0: ERR: element not found

in der etc/default/ebusd steht
EBUSD_OPTS="-d /dev/ttyebus -p 8888 -l /var/log/ebusd.log --scanconfig --httpport=8080 --mqttport=1883 --mqttjson --mqtthost=10.0.0.5 --mqtttopic=ebusd/%name --httppath=/var/ebusd/hmtl"
steht nur
EBUSD_OPTS="--scanconfig"erhalte ich den selben Fehler im log.

Kann mir hier jemand helfen?
Bin zwar technisch, sowie am PC sehr fit. Jedoch fehlt mir einiges ein Linuxerfahrung.

gruß,
Markus


edit:
EBUSD_OPTS="--device=/dev/ttyebus -p 8888 -l /var/log/ebusd.log --scanconfig --httpport=8080"
hiermit kommt zumindest kein Fehler mehr.

dafür viele

Ein Fortschritt ;-)

ich mache morgen weiter

das passt eigentlich nicht zusammen... Da muss ein anderer Fehler in der /etc/default/ebusd gewesen sein.

Verstehe das auch nicht. Habe nur die Zeile kopiert.

Momentan funktioniert es. Allerdings fehlen IMHO noch einige Funktionen bzw. Werte.
Außerdem sagt mir die Versionsanzeige "3.0pre.bbc4d04" obwohl sicher die 3.1 heruntergeladen wurde.

gibt es noch eine einfachere Möglichkeit die Sensoren den richtigen Werten in der Steuerung (Vaillant Auromatic620) zuzuweisen?
