How can I disable the error "Failed to start Network Time Synchronization" when using Revolution Pi Core 100102?
...
b) Change the USB driver to dwc_otg. Instructions, which can be provided on request, can be found here: Run Buster Image on Revolution Pi Core (CM1)
I don’t enough space to upgrade my Revolution Pi Core 3. What can I do?
please have a look here: (40) Can't upgrade - Revolution Pi Forum
I have a network problem. When I try to connect directly to the Revolution Pi via Ethernet, I have problems with the connection. This can be avoided by connecting a switch in between, what can I do?
We can confirm that direct Ethernet connections without an intermediate switch do not work reliably with the recently released 5.10 kernel. The 4.19 kernel we’ve used before does not exhibit the issue. A fix is underway here. We’ll release a kernel update shortly.
How can I avoid the problem?
The Ethernet port on the front of the Revolution Pi Core uses Auto-MDIX for automatic detection, which does not always work reliably. Disable Auto-MDIX and configure the connection speed and duplex mode manually.
sudo ethtool -s eth0 duplex full speed 100
I use Modbus-RTU and after a restart of the Revolution Pi there is an error in the register. What can I do?
Unfortunately, this is a known problem that has been reported here:
https://revolutionpi.de/forum/viewtopic.php?f=14&t=3156
After the reboot the value 0x11 is in the register "Modbus_Master_Status".
Even if I write the value 1 into the register "Master_Status_Reset", the error remains.
If I reset the driver via PiCtory or use the command "piTest -x", the "Modbus_Master_Status" register shows the hex value 0x00.
I have problems with USB and I use a beta image what can I do?
The beta image is not supported. However, there is a workaround for this problem
The wrong USB driver is loaded (error in BEta image). This can be solved by prepending a line with [pi4] to the [cm4s] section (/boot/config.txt). Please try as follows:
| Code Block |
|---|
[cm4s]
dtoverlay=dwc2,dr_mode=host
#dtoverlay=vc4-kms-v3d
#max_framebuffers=2

I want to use the serial gateway and for that I need a software is that correct?
Yes that's right. The GATEWAY Module for serial network you may need the the KUNBUS-Scripter.

I would like to bring data from a PROFINET application to the cloud. According to my research, the S7 PUT/GET protocol can be used with Revolution Pi7, can you confirm this?
We have no stock in Revolution Pi7, here is a quick guide however Supported this is not active.https://revolution.kunbus.de/forum/viewtopic.php?t=854
However, yes exactly that was the goal of Revolution Pi7 namely to read and process data from the data stream of the Profinet network.
