Troubleshooting firmware upgrade installations

The main types of error that might occur during installation of a firmware patch are:

Show/hideVersion problems

A patch targets a particular major.minor release version of the software. It might contain:

  • new components that are not in the targeted software

  • updates to components that are already in the targeted software.

If there is a problem installing a patch, a dialog box appears to inform you of the problem:

  • If the patch targets a version of the software that is not installed, the dialog box shown in the following figure appears:

    Figure 61. Error when installing a patch to uninstalled software

    Error when installing a patch to uninstalled software

    In this case the patch is not installed, and the software on the debug hardware unit remains unchanged. Make sure that you have the patch for the version of the firmware that you have installed.

  • If the patch does not contain any new or updated components (typically because a later patch has already been installed), the dialog box shown in the following figure appears:

    Figure 62. Message when installing a patch that has no new components

If you see one of these dialog boxes, click OK.

Show/hideErrors during file operation on the host

If an error occurs during file operation on the host, a dialog box appears to inform you of the problem:

  • If the error occurs before any data has been written to the compact flash, the dialog box shown in the following figure appears:

    Figure 63. Error before data has been written to compact flash

    Error before data has been written to compact flash

    Click OK and begin the installation again.

  • If some data has already been written to the compact flash when the error occurs, the debug hardware unit must reboot to clean up the failed installation and revert to the backed up state. The dialog box shown in the following figure appears:

    Figure 64. Error during writing to compact flash

    Error during writing to compact flash

    Click OK. The debug hardware unit reboots. You can then begin the installation again.
