KK Multicopter Flash Tool Uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/librxtxSerial.jnilib:

kkmulticopter logoIf you just downloaded the KKMulticopter Flash Tool on Mac OsX, like me and once launched you get: Uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/librxtxSerial.jnilib: no suitable image found. Did find: /Library/Java/Extensions/librxtxSerial.jnilib: no matching architecture in universal wrapper

Your Solution is:

delete this file :
/Library/Java/Extension/RXTXcomm.jar

and all will go fine. Just keep that file, for future needs.

Hope this helped!

  1. I am unsure of how to remove or delete the file /Library/Java/Extension/RXTXcomm.jar
    I have typed this in the terminal but it was unable to find it. I am sorry but I am not very computer literate. Where do I find this file, and how do I delete it?
    You will have to give me pretty explicit directions step by step if you could.
    Sorry but I am just a dumb blond

    1. Hi, I’m sorry but in the meanwhile i switched to Debian on all my systems, for this reason I’m not able to check for the file location. I suggest you to use the utility “locate” which should be present in osx. so if you type in a terminal “locate RXTXcomm.jar” it will output all locations matching that name (or as part f the name). I hope this will point you to the right direction. Let me know.

      Giuseppe
