Re: Non-monotonic clock when rebooting with no internet access
Hi Johannes, Thank you very much for your reply. There is a lot of good information. touching /var/lib/systemd/clock at some regular interval works well and the system does not "go back in time" more than whatever interval is chosen. You mention that the file should not be written to const...

Re: Non-monotonic clock when rebooting with no internet access
The RTC on the Pi does not seem to be used in this case. Rebooting the system results in the RevPi's time being set back in time upon reboot, possibly by several weeks or months. I'm rebooting with "shutdown -r" so the RevPi is being continuously powered while it is restarted.

Non-monotonic clock when rebooting with no internet access
We are using a RevPi on a product and we do not always have access to the internet. We are finding that when the RevPi is restarted it sets the clock to the last time it had access to the internet. This results in time “going backwards” An example will help: 2/1/2021 - RevPi is on and has internet c...

Re: DO module: Detecting open load
That page had some good information on it. After configuring OutputOpenLoadDetection how do I check to see if there is an open load on an output? In digging a little bit I did come across this page: https://revolution.kunbus.com/tutorials/what-is-pictory/revpi-dio-pictory-configuration/ which includ...

DO module: Detecting open load
The page describing the I/O modules mentions:
Thanks,
Andy
How do I read or get notified of the alarm when there is an open load condition?Each output can additionally be configured to detect open load conditions when in high side switch mode and send an alarm to RevPi Core.
Thanks,
Andy

Re: Detecting presence of watchdog jumper
GPIO42/WD_IN is the watchdog chip's input, which I'm toggling periodically.
I am looking for a way to determine if the watchdog jumper is present on the X4 connector. From the schematic I believe this line, after conditioning, is labeled "WD_EN (from Pin3 X4 connector)."
Thanks,
Andy

Detecting presence of watchdog jumper
Is there a programmatic way to query the RevPi to determine if the watchdog jumper is present?

Part Number for X4 connector on RevPi connect
Hi,
We would like to buy replacement connectors for the RevPi. Do you know where we can buy these connectors?
Thank you,
Andy
