RPi zero uses a different CPU architecture which apparently is not supported by jssc. jssc is based on native binaries that must be precompiled with the correct architecture.

 

[Blueforcer]

Do you have an older jSerial Lib? Because it worked in the past before i updating the lib.

 

[Erel]

The old jssc.jar is available here: https://github.com/scream3r/java-simple-serial-connector/releases

What about the slf4j jar?
Get also this error

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/D:/OneDrive%20-%20dinotec%20GmbH/B4J/Libraries/moqueutte.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/OneDrive%20-%20dinotec%20GmbH/B4J/Libraries/slf4j-jdk14-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

Maxbe you can give me the complete last jSerial for B4j lib?

 

[Erel]

The difference is just in the xml file. Remove the dependency of "slf4j-jdk14-1.7.25".

Make sure to refresh the library afterwards.
