Re: RevPi failed to get modem status
Hi RMeissnerCC, from the kern.log and lsusb output you've provided, it can be seen that a 4-port usb hub has been used to connect all the usb-serial adapter. And it seems that all the failures(which are indicated by error No.-110 as timeout error) are happened on that usb hub. My sugesstion is, mayb...

Re: Monitor Auflösung RevPi Core 3
Hallo Matthias, Ein weiterer Punkt. Die Konfiguration der Auflösung in raspi-config ist nur lokal gültig, d.h. wenn Sie sie mit einem Monitor oder ohne Monitor konfigurieren, gilt sie wahrscheinlich nicht für andere Monitortypen. Wenn Sie die spezifische Auflösung auf einem Monitor mit einem Gerät v...

Re: Confirmation: RpiCore 3 image resize on 3+
/usr/sbin/revpi-factory-reset: line 49: /usr/bin/dtoverlay: No such file or directory I assume by "new behaviour" you refer to the above-quoted error message? That message means that the devicetree overlay for the RevPi Core could not be loaded. The most likely explanation is that the /bo...

Re: Time and date wrong on RevPi: RTC backup not working?
you are welcome Ray,
maybe you can also post the kern.log here, then I can check whether other suspicious points are there.

Simon

Re: RTC:The time is incorrect after each restart
Hi Huanghuapan, this happens while linux is trying to read the time on the rtc device. It might be caused by the damage of the devicetree, or fault of hardware. Could you please post the output of following commands for the further debugging: cat /proc/devices cat /proc/driver/rtc ls -l /dev/rtc* su...

Re: Time and date wrong on RevPi: RTC backup not working?
Hi Raydodo, It's fine, never mind. And it's a good news that you get some progress. I think the setting is always correct depending on your scenario. In your setting, it is assumed that you are located in GMT, +0000, you want to synchronize the time of your device with NTP server, which may be confi...

Re: dwc_otg interrupt rate
Yes, from https://github.com/RevolutionPi you can get the stable version for Connect+, which is revpi-4.9. The factory image is also built from source code of this repository. If I were to build a Kernel using the Kernel Bakery on GitHub and re-flash the Connect+ , would it have the fixes or do thos...

Re: Unexpected change of system time
Hi Alf, before "All of a sudden", what have you done with the device ? Has it ever been powered off more one day ? It seems this normally happens when linux can not read a correct date/time from RTC hardware which can be powered by a super capacitor only about one day. One Revpi Connect is...
