/2023.

...

Would it be possible to upgrade Python?

Since we unfortunately don't have a Bullseye release yet, I can show you the following ways:

  • Every major release of Debian comes with a certain Python version. If you need a different Python version, you can either try to compile the newer Python version (but there might be problems because other system components depend on /usr/bin/python3 and expect a certain version)

I would like to run my Revolution Pi 64 bit. Is there any experience?

Can I modify the kernel module

“piControl” in my Revolution Pi Module?

Can I install Java runtime and start my program on this device? Has it X server and access to GPIO from the box?

We have many customers who work with Java on the system. http://www.elbfisch.org/index-de.html

for example:
They've completely ported their system to our Revolution Pi.
How to install Elbfisch on a Revolution Pi you can find [url=https://github.com/mskgmbh/elbfisch/wiki/How-to-install-Elbfisch-on-a-RevPi-Core-3-(Revolution-Pi)%5Dhere%5B/url%5D.

I cannot update via “apt update” what can I do?

Check your network configuration. If you have configured a static ip IP address, you probably need to add the nameserver to /etc/resolv.conf.

piControl

Error: too many communication errors, RevPiStatus = 1) means: At least one I/O module is connected that has not been configured by PiCtory.

Recommendation:

  • Rebuild your pictory PiCtory configuration. From your SOS Report, I see 9 unknown moduletypemodule type, and I am wondering wonder about that , because it is supposed to be 11 Modules and I see 20 modules.

  • Are the PiBridge connectors connected stable?

  • Update your system

...

  • Check if you can do a firmware update of the I/O. Just connect one I/O Module at a time.

Can I convert Modbus TCP messages to MQTT messages

...

addressed to a MQTT Broker?

Yes, but you have to go the way and disable the Modbus services, i.e., in the WebStatus. Then you have to adapt the libModbusMaster yourself according to your needs. Have a look at https://libmodbus.org/

Can I debug the boot process of a RevolutionPi Revolution Pi module?

In general, there are different possibilities to output the messages on serial interfaces during boot:

Can I use the RaspberryPi Raspberry Pi Lite image on the RevolutionPiRevolution Pi?

Not by default, but you have the following options to make that possible:

Can I use the RevolutionPi Revolution Pi image on a RaspberryPi Raspberry Pi device?

No, because the image was adapted to the RevPi hardware.

I want to access

GPIOs of the CM. But the watchdog prevents the access. Can the watchdog be configured someway to prevent this issue and if so, how can this be done, please?

No, That watchdog feature is implemented in hardware. It cannot be disabled.

If you use virtual machines switching to USB 3.1, all flashes run cleanly.

tried to assign an IP address 169.254.60.100 via DHCP server, but it is not set on the RevPi. What can I do?

This does not work either. No IP address can be assigned from the range managed by the APIPA protocol.

Please use consider using another network which is outside the address range.

  • The most common causes seem to be

    • USB extension

    • Insufficient power supply to the USB port

I sometimes get the error message

“getSerNum() failed -

Please update your system and do an error handling because the error can sometimes occur because the chip goes to sleep. See discussion here:

I want to port the image, e.g., to Yocto and I have problems, what can I do?

You can look up how we did it for porting an image. So to build your own image, use the code and instructions on Git HUBGitHub:

I have configured modules in

...

PiCtory and after reading with piTest -d I don't see any other modules except the main RevPi module. What can I do?

You have to save the configuration and reset the driver. See the Link below:

What can I do?

The default username for log logging in over SSH is default: pi
The default username for log logging in over PiCtory is : admin

To this problem issue, we have a possible solution in our forum.

  1. Installing a new image

    1. Download Image from one of these links https://revolutionpi.com/tutorials/downloads/?noredirect=en_US#revpiimages

    2. Transfer data to a new image and possibly reinstall the respective software.

  2. Install the current system via "apt”“apt”

    1. changing the "stretch" to "buster" “stretch” to “buster” keywords in the following files:

I have successfully installed the latest Ubuntu 22.04 on the Rev Pi Core, now I would like to configure the Real-Time Clock.

Is there any experience in the Debian 10 area?

I installed Ubuntu 22.04 Server on a

Revolution Pi module, but I am having

troubles with the networking device, is there something that I can do?

The Ubuntu kernel lacks the devicetree DeviceTree overlay for the CM4s → so it can't work without customization. We have forwarded a message to the development team. Possibly the problem will resolve itself.
