Hallo Kristian,

mit dem Befehl sudo hwclock kannst du die Uhrzeit direkt vom Uhrenbaustein (RealTimeClock, RTC) abfragen. Wenn dieser Befehl Fehler oder falsche Werte anzeigt ist davon auszugehen, dass die RTC nicht richtig funktioniert. Wenn der Gold-Cap defekt ist, sollte die Uhrzeit nur bei ...

Hi user123,

there is no straight forward way to install an update with an usb drive.

As our systems are based on RaspiOS/Debian it should be possible to create an usb driver with a package repo to update the device. This is not straight forward and we have no documentation on the process. If you ...

PiControl doesn't use C++ and we don't provide a C++ library.

PiCOntrol provides a device file:
/dev/piControl

To work with piControl you need to open the device file and interact with the process image. We have an example program to show how this is done:

Hi Peter,

it should be possible to use the RS485 as console. But be aware, that the RS485 on the Connect(+/S) is connected via USB. This has some impact on some minor use-cases. So you only get output from the console after the USB subsystem is initialized. This is later in the kernel startup. But ...

The RevPi Connect 4 has no watchdog jumper anymore. The watchdog jumper was needed on older Connect models.

Best regards,

Hi underhood,

if you don't use any extension modules (DIO, AIO, ...) and you don't use any revpi specific tooling (revpimodio2, Node-RED-RevPi-Nodes, ...) you can disable the piControl kernel module:

In /etc/modules should be an entry for piControl. You can remove or comment this entry out. But ...

Hi Chris,

thanks for the feedback. It would be great if we could get as much information about your setup as possible. If you don't want to share this in public you can send this to support@kunbus.com. Please put a link to this forum post, then we know it is related to this conversation.

A different idea, we released the 6.1 kernel for RevPi a short while ago. We needed to change how the communication between RevPi and IO modules is implemented. We didn't get any bug reports about it, but you might test the 5.10 kernel.

sudo apt install raspberrypi-kernel=1:9.20230926+1-5.10.152-1 ...

Hi,

this looks pretty strange. Could you temporarily flash an up to date image?


create an image from your device
flash a current image
test if this also happens with this image
reflash your old image


This way we could check if this might be an H/W issue (unlikely, but possible) or if this ...
