Re: [ts-7000] Re: RXTX receive problem

[Jeremy Freeman <>]

We had similar problems trying to compile rxtx on our 7800. What I ended up doing was switching to using EABI root filesystem and installing the precompiled rxtx from the Debian repository. Debian keeps the EABI (armel) binaries far more up to date than the arm binaries. It works perfectly and have been running it in production for 5 months now.

Word of caution, do not use high serial IO and SD card writes at the same time as myself and others on here experienced frequent lockups.

Hi Carlos,

 

I cannot help you about the information you are asking me because in fact I couldn´t load correctly my aplications which use rxtx library. When I try to start my java aplication I receive allways the same error:  It says that it is unable to find librxtxSerial. so library, but when I indicate it with -Djava.library. path option or with LD_LIBRARY_PATH enviroment variable I don´t success, (of course locating my librxtxSerial. so in all the directories where System can try to find it.... I have check all the posibilities) .  Because of this I am trying to compile by my own librxtxSerial. so library to be sure that tha one I have is the correct.. in fact in my PC runs perfectly)

 

Do you know how to help me??? 

 

PD: Maybe is an Operating System problem??? I am usind the last one Debian version for the TS7800 board.

 

 

thanks

Hi,

The program detect serial ports?
