That's strange. Which IP did you use in your (successfull) test with CodeSys?

Hi Guest11740 Good catch! You're right, The destination IP in my iptables example must be the IP of the PLC. Could you please test if the port is shown as open by using a port scanner like nmap? # install nmap package sudo apt install -y nmap # scan port on localhost nmap -p11470 127.0.0.1 nmap -p11...

Hi Guest, unfortunately it is not possible to use a remote host with AWS SSM port forwarding. But as you already figured out, you can create a local port forwarding from your PLC to your RevPi and point AWS SSM to your local port. For a quick test you could use the following echo 1 | sudo tee /proc/...

Hi Aurelog,

thanks for also letting us know in our communiy forums. Resolving this issue is important for us aswell. We are in close contact with the developers at our partner Erminas and working on a fix for this issue.

Hi Daniel,

is the piSerial error permanent or does it only occur irregularly? The error is raised when the chip is in sleep mode but usually it should work in the subsequent call as described in the thread you already found.

Hallo Tuscan,

bitte mal mit einem anderen USB Kabel probieren (manche sind nicht vollständig belegt und daher nur zum Ladne geeignet). Hast du ansonsten die Möglichkeit das Flashen einmal mit einem Linux Rechner zu probieren?

Gruß Nicolai

Hi Gianni,

thanks for all the informations. I'll try to reproduce the error with my test setup, but can't promise anything yet. As I understand you last post the solution with piTest works for you - at least for now.

Hallo Tuscan,

so wie es aussieht findet rpiboot kein Device. Kannst du bitte einmal andere USB Ports testen und ggf. andere, nicht zwingend notwendige USB Geräte trennen? Welche Version von rpiboot hast du im Einsatz?

Gruß Nicolai

Hi Roger

You can ask revpimodio2 related questions in the subforum of our makers corner: https://revolutionpi.de/forum/viewforum.php?f=41. Sven (the author of the library) frequently reads there and tries to answer the questions.

Hallo Tuscan,

ich würde sicherheitshalber zusätzlich die Lizenz wie beschrieben exportieren.
