Was wir gestern schon aufgedeckt haben: Mit dem FiPy funktioniert make list-boards, mit dem WiPy nicht.

Hi Clemens,

wir sollten hier noch etwas dran schleifen.

image

Alles richtig!

Sollten wir vereinfachen zu “make setup”.

Ja, das wäre natürlich auch toll, das verbessern zu können. @einsiedlerkrebs, @tonke und ich haben schon ein paar Ideen dazu. Manuell kann man darauf inzwischen durch gezielte Deaktivierung entsprechender Zeilen in den tools/*.rshell Dateien einwirken.

Schau ich mir an!

Allerdings:
Wenn der Ordner jedoch bereits existiert, kommt glaube ich eine ähnliche Fehlermeldung, die man aber getrost ignorieren kann. Fragen: a) Was passiert denn danach? b) Kannst Du mir die Ausgabe von git diff am Telefon vorlesen, damit wir uns der Sache nähern können? Danke!

bei port fehlt eine Portangabe, äquivalent zum Beispiel darüber (make recycle).
Wo auch immer die gesetzt wird, oder wie auch immer die bei Windows “gewonnen” wird…

Problem

Korrekt, in dem Fall ist die Meldung eindeutig:

rshell: error: argument -p/--port: expected one argument

Danke!

Ursache

MCU_SERIAL_PORT ist nicht gesetzt, siehe configure serial port for Hiveeyes MicroPython Datalogger. An einigen Stellen wird das bereits rechtzeitig abgefangen, aber scheinbar noch nicht überall, deshalb brauchen wir mehr Tester und mehr Programmierer.

Fazit

Vielen Dank für die Meldung und Analyse, beim nächsten Release versuche ich einige Stolperfallen für Anfänger zu verbessern, speziell in Richtung Setup commandline-based MicroPython development environment on Linux, macOS and Windows sowie Settings.py der Hiveeyes Micropython-Firmware. Sorry dawei, @clemens!

Für mich würde die Info hier z.B. nicht reichen. Setup installiert für mich als DAU irgendwas lokal. Abhängigkeiten können auch von irgendwelchen neu installierten Paketen kommen. Für mich könnte das genauso gut irgendwas mit der “developer sandbox” zu tun haben, dass dafür der FiPy angeschlossen sein muss und der Port definiert sein muss, erschließt sich mir hier nicht, steht auch nicht in der Doku!

Sorry, wenn ich hier nerve, aber wenn wir das nicht halbwegs nachvollziehbar hinbekommen wird da keiner Testen, wenn ich hier nicht mit im Team wäre hätte ich auch schon längst aufgegeben und gesagt, ok, Sch… MicroPython, nehme ich halt die Arduino IDE. Bitte nicht falsch verstehen, ich halte das aber fürs Projekt essentiell!

Problem

I’m getting a core dump on 1.18.2.r4 (v1.8.6). It happens only on cold start (machine.reset()) triggered by make recycle. After pulling the plug using warm start (CTRL+D), the Firmware boots and runs flawlessly (see success below).

But sometimes make repl is working:

… und was ist mit dem hier?

19

Alles was hier steht ist relevant für Verbesserungen auf dem Weg zum 0.3.0 Release. Der Stand vom master lief zuletzt auf den Gerätschaften @tonke mit ziemlich viel Hardware dran, während @clemens gerade auf einem nackten FiPy unterwegs war.

Die Robustheit zeigt sich bereits jetzt, dass die Firmware in diesem Fall nicht zwingend abstürzt. Das war ein wesentliches Ziel meinerseits. So können wir zukünftig auch Hardwarefehler über die Telemetrie fernmelden.

Es ist jedoch durchaus möglich, dass just dieser falsche Buszugriff im Kontext von “direkt nach dem Kaltstart” doch zum core dump führt – “Unhandled Exception” deutet irgendwie darauf hin. Schau ich mir an!

Bottom line

This works, sometimes even on LinuxOnWindows. However, it’s still flakey and has rough edges, especially on the documentation side.

# Find serial port
make list-serials

# Configure serial port
export MCU_SERIAL_PORT=/dev/ttyS16

# Pre-flight checks
make list-boards

# Bootstrap dependencies once.
# Usage: After updating the list of dependencies, e.g. through "git pull".
make setup

# Upload user-space firmware and trigger a cold start.
# Usage: Each time you modify code.
make recycle

Instead of the serial port, you might want to run this over the network by configuring the IP address like

export MCU_SERIAL_PORT=192.168.178.42

However, this obviously only works when the device has joined your local WiFi successfully.

nun, ich weiß ja garnicht , ob da tatsächlich ein BME280 dran ist (und wenn, ob auch an den definierten pins), insofern kann ich nicht einschätzen, ob das “nur” ein bus timeout war, weil an der gewünschen I²C-Adresse kein Gerät nach $zeit geantwortett hat, welches der Proz da erwartet hat.

Man könnte sowas zu Laufzeit quasi enumerieren, indem man á la i2cscan nicht alle, aber alle irgendwo definierten I²C-Adressen anfragt und, da die Fehler “vom System” abgefangen werden™, weitere Abfragen irgendwelcher I²C-Sensoren vom Ergebnis dieses ersten scans abhängig macht… aber muß man auch nicht, ist eher bei 1wire üblich. Zukunftsmusik.

Fragen

Datenübertragung belauschen

Wenn ich die REPL-Ausgabe richtig interpretiere werden nur die Daten des BME übertragen. Wo kann ich sehen, was tatsächlich übertragen wird?

Sensoren zuschalten

Warum werden die DS18B20- und Waage-Daten nicht übertragen? Angeschlossen sind 5 DS18B20 und eine Wägezelle.

Überflüssige Konfigurationsschnipsel entfernen

Muss ich die Sachen ab 'bme280_1': löschen oder können die da stehen bleiben?

Probleme

"make recycle" freezes

Weiter habe ich immer noch Probleme mit make recycle, manchmal funktionierts, manchmal bleibt es ganz am Anfang hängen. Wenn es durchläuft kommt manchmal die Ausgabe eines core dump …

Das war ein nackter FiPy, so werde ich es auch gleich bei mir nochmal nachstellen. Der aktuelle Stand im master plus settings ist einer, der aus einer voll ausgestatteten Hardwarekonfiguration von @tonke stammt.

Wir sind da dank @einsiedlerkrebs und gemeinsamen Anstrengungen des Backdoor Collectives durchaus schon in diese Richtung unterwegs. Wäre saucool, wenn wir diese Details wie Du sie ansprichst dann gemeinsam mit Dir festnageln könnten (i2cscan-sattelfest bin ich ja leider auch nicht so, mir ist aber klar, dass wir da konzeptionell viel ableiten könnten). Aber auch Vincent hat hier per GitHub - vkuhlen/bob-webserver-demo und GitHub - vkuhlen/bob-frontend-demo bereits funktionierende Softwarestücke, gerade für die Enumerierung bzw. Zuordnung der 1wire Sensoren.
