getting java.lang.UnsatisfiedLinkError when running as modbusmaster

[torgeir123]

Hello,

I am experiencing problems running the following code:

      ModbusFactory factory = new ModbusFactory();
      
      SerialParameters params = new SerialParameters();
      
      params.setCommPortId("/dev/ttyM0");
      params.setBaudRate(9600);
      params.setDataBits(8);
      params.setParity(0);
      params.setStopBits(1);
      
      RtuMaster master = (RtuMaster) factory.createRtuMaster(params);
      
      
    try {
        master.setTimeout(1000);
        master.init();
        
          List<Integer> slaves = master.scanForSlaveNodes();
          System.out.println("slaves: "+slaves);
     
    } catch (ModbusInitException ex) {
        Logger.getLogger(modbus.class.getName()).log(Level.SEVERE, null, ex);
    }

when I run the above code, I get the following error:

java -cp lib/ -jar HaystackClient.jar
log4j:WARN No appenders could be found for logger (com.serotonin.io.serial.JsscSerialPortProxy).
log4j:WARN Please initialize the log4j system properly.

Two strange things:

1: The file in the error message actually exists
2: The processor is an ARMv7 Cortex-A8 which has hard float, so it doesn't make sense to load armsf lib.

Any ideas would be greatly appreciated :-)

you run on a linux system. please confirm the serial com name is "/dev/ttyM0"? right?
and this should be a jssc environment problem,pleause comfirm if you lose some jar lib
