Chapter 7 Upgrading to FDT 3.1
Installing FDT 3.1 should not adversely affect your other FDT version installations. The USB driver will be
upgraded by installing FDT 3.1, but this is the only shared component. Each version of FDT installs its own set
of kernels and keeps its own settings. Installing FDT 3.1 will also update the support email addresses for some
previous versions of FDT.
If you are an existing user of FDT, and your existing project needs to be migrated to FDT 3.1, the
recommendations are as follows:
If the project specifically requires the kernels distributed with an earlier version of FDT (or a customised kernel
based upon an older version), it is possible to choose the “Other” option to select the “User Defined” kernel. It
is recommended however, that wherever possible, the latest kernels be used. Using kernels from previous
versions of FDT may lead to a decrease in functionality (e.g. FDT 3.1 kernels include the information that FDT
requires to calculate the asynchronous serial error rates; use of older kernels will result in this feature being
disabled).
For projects using FDT versions prior to FDT 3.0, a new workspace and project should be created using the
wizard. This will ensure that the new settings are generated as required by FDT and is a very quick process
using the Project Wizard. The workspace files used by FDT versions prior to version 3.0 are not compatible
with FDT 3.1 due to the enhancements included in FDT 3.0 and 3.1.
FDT 3.0 Workspaces can be opened with FDT 3.1 but should not be opened with FDT 3.0 again after they
have been upgraded. Any errors related to “SyntaxHighlightingFile.dbs” can be ignored in this case. Toolbar
positions and states may also be affected by opening FDT 3.0 workspaces.
