But communication is not being started in Some PC it will work as such in my PC it will work smoothly but in my colleague it will not work as such we found the Port is not being open successfully by that communication software and we monitor the action in background around the port is like below.

    Hello Smit,

    Did you base your application on an existing TivaWare example? Also did you try you application on a TI provided board, to eliminate hardware issue?

    Are the drivers installed correctly on the PC on which the problem is noticed? Also what software are you using on the PC to communicate with TM4C device?

    Thanks,
    Sai

    1) Yes it is in Existing TIVA ware Version.
    2) No but in some system it will work and others dont.(we have observed with Windows 7 32 bit it works fine but in Windows 7 64bit it will not work)
    3) Drivers are installed perfectly as it shows the TIVA Ware COM Port and its number too.
    4)we have used Modscan 32 and various other.

    If your application is based on a TivaWare example, then please test the TivaWare example on a TI board on both the PCs. This way we can eliminate the hardware issue and focus on the software. Right now I cannot provide much help based on the information provided.

    Can you provide the name of the driver that is installed? Also is the same version of the driver installed on both the PCs?

    Thanks,
