Hi,
I upgraded to Buster today.. but the keyboard and mouse is not responding very well.
As a result I can't log in via the console.

Good news.. after I upgraded the firmware to the june2020 version, I can now run the opcua server with encryption enabled.

However, when I tried to connect using a ua client (eg. uaExpert), the server crashed.

I realize that the version you used is june2020, whereas mine is mar2020.
How can I upgrade mine to june2020 to attempt another test ?

Step 2: should be
openssl (https://cloudwafer.com/blog/installing- ... -04-18-04/)
sudo apt install build-essential checkinstall zlib1g-dev -y
sudo wget https://www.openssl.org/source/openssl-1.1.1h.tar.gz
sudo tar -xf openssl-1.1.1h.tar.gz
sudo make; sudo make test; sudo make install

This is what i got:

pi@RevPi39718:~ $ uname -a

Hi Kirk,
I did some digging and dump out the log entries during runtime. Comparing between a regular RPI and RevPi, this is the difference:

On RevPi Core 3+

Thanks Dirk.
Today I started the installation of the following packages into RevPi Core3+ acting as the opcua server.

1. Open62541
2. Xml2
3. OpenSSL

I then compile my c code and when I run the server code on revPi, there is no problem.
However when I use UAExpert to connect, the server crashed ...

Currently I use 2 DIY raspberry pi to setup a Linux environment running gnu c libraries.
1. 1 opcua server
2. 1 opcua client

Communication is via tcpip port 20004.

I intend to upgrade my equipment to kunbus and port my executables from raspberry pi to kunbus

Question:
1. Can the base kunbus OS ...

correction::
since the intent is to use azure IoTEdge, should the product used be RevPi connect+ ?
