    Hi Umesha,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). 

    Moved this thread to Code Composer Forum for faster response.

    1. Please provide the CCS version?

    2. Have you installed the CCS with root permission? If not re-install CCS with root permission(to install emulator packages).

    Thanks.

    Thanks Rajasekaran,

    I have been using CCS5.2 and i have installed with root permission. After installing CCS, it asked me to install all drivers, i.e install_driver.sh in ti/... path. I did that but it didn't install it successfully. Any patch is required as I changed os to 12.04.4 version?

    Hi Umesha,

    I am not aware of it. The CCS experts will help you shortly. 

    Thank you for your patience.

    Hi,

    I would first check the Linux install instructions, as there are significant differences between Linux 12.04 and 10.04.

    http://processors.wiki.ti.com/index.php/Linux_Host_Support

    http://processors.wiki.ti.com/index.php/Checking_Linux_Dependencies_for_CCS

    If you installed CCS after updating your OS, then I think most of the potential issues with missing libraries (as shown in the above pages) would have been covered. If not, I would potentially reinstall CCS and see if by any chance a library is missing and is causing the connection issues.

    Actually, I would install a newer release of CCSv5 (5.5) or even CCSv6, as support for Linux improved a lot since CCSv5.2 was released. You can even install it in a different directory and use a different workspace to compare the two.

    The error message you are getting is indicative of the failure in initializing drivers/recognizing the emulator by the system. A common error is the <install_drivers.sh> is not properly run at the end of the install, but it seems you already executed that utility.

    To further debug this, try to run the xds100serial utility as mentioned in this thread. This will verify if the system is recognizing the emulator.

    If the utility can't recognize the emulator, try to change the USB port as this usually makes Linux to re-enumerate the devices (and the device driver properly initializes).

    If the utility can recognize it, try to run the Test Connection button from the Target Configuration Editor. This usually brings some additional insights to what may be happening.

    I everything above is ok, I would try to connect manually to the target and see at what step the operation fails. Step 4 of the link below shows how to do this and several additional tips to troubleshoot this issue.

    Hope this helps,
