Hello,
During our last tests using a Core3+DIO+DO+AIO modules, we noticed that they all boot fine,
work for some time, and suddenly we have a communication problem between the modules.

We noticed that the Power LED from all modules goes always ON. According to the documentation,
this means that there is something wrong with the PiBridge, but why after a reboot it works again
(sometimes for even hours until stops again)?

Could it be really a hardware problem or maybe a software problem, which is causing the PiBridge
communication to fail? We are using currently Python3 with RevPiModIO2.

Is there somewhere a details log about the PiBridge where we can check from where comes this failure?

Many thanks in advance,
Nathan

Not even a suggestion where I can check if there was
an error or something related to the PiBridge? Is there somewhere
on the system a log file regarding this communication between the modules?

Hi Projektraum,

could you please update your RevPi Core

Code: Select all

sudo apt update
sudo apt upgrade
sudo reboot

and update the firmware of you modules?

Update Modul Firmware

If these actions don't help, we need an SOS report to look for this issue.

Here is the instruction for the SOS-Report:

Code: Select all

sudo apt update
sudo apt install revpi-tools
revpi-sos

Instruction for the command:

Code: Select all

pi@RevPi40302:~ $ revpi-sos
The report will be generated under folder /tmp in a .tar.xz file, which
can be extracted with command: tar -Jxvf xxx.tar.xz in linux or 7zip in Windows.
And then some inspection can be done before it is sent to support@kunbus.com.
