Re: Adding Balena-OS support for revpi-connect-4

I've created a PR for Balena which adds our udev rules to the integration: https://github.com/balena-os/balena-ras ... /pull/1148

Re: Adding Balena-OS support for revpi-connect-4

Hi Lukas, the device /dev/ttyRS485 is an alias created by our udev rules. As far as I know this is not present in Balena. But you can use the "real" tty device: pi@RevPi99986:~$ ls -l /dev/ttyRS485 lrwxrwxrwx 1 root root 7 2. Jul 12:54 /dev/ttyRS485 -> ttyAMA5 Thus the correct tty is /dev/...

Re: DMX-Protokoll an RS485

Hallo Markus,

Ich habe selbst schon erfolgreich dmx mit Python und einem RevPi Connect 4 implementiert. Der uart ist ganz normal als tty im Linux verfügbar.

Re: Several issues with Connect 4

Regarding the mac: Looks like everything works as intended. `ethtool -P` requests the permanent mac address which is set in the compute module. The mac address is overriden by a udev rules in order to match the assigned address for the individual device. In order to get the _used_ mac address for a ...

Re: Several issues with Connect 4

Regarding the MAC: Which address is printed on the cover? Does the mac address in revpi-device-info match the address? Other issues: Check wether the /var/log/ tmpfs feature is active (revpi-config status var-log.mount) and disable it if it is present (revpi-config disable var-log.mount). Sound like...

Re: RevPi Connect 4 - Modbus /dev/ttyRS485 nicht vorhanden

Sind auf jeden Fall schon mal einige eher ungewöhnliche Probleme in Kombination. Ich schlage daher den RMA vor.

Re: piControl: AIO addr 31: communication failed (req:20,ret:-5)

Hi, we did some investigation and nailed it down to probably an issue in the serial communication with lower (<=9600) baudrates. The same issue can be observed with kernel 5.10, but only less frequent. At the moment our developers are checking how this can be solved with our driver or an upstream pa...

Sieht unauffällig aus. Um einen Hardware Defekt auszuschließen versuche es bitte einmal mit dem aktuellsten 64-bit Image. Du findest es in unserem Downloadbereich. Falls dann der Fehler immer noch auftritt, schlage ich vor den RMA Prozess beim Verkäufer zu starten.
