Flash Protection
8.2 About flashsecurity.txt
The FPMP file, flashsecurity.txt, is added to each new project and appears in the Workspace
Explorer.
Figure 8-1. flashsecurity.txt in Source Tree
PSoC Designer also adds the FPMP file to a cloned project. This is especially useful when cloning
projects created with earlier versions of PSoC Designer because earlier versions did not carry this
feature. Note that if you do clone a project created in an earlier version of PSoC Designer, you are
prompted to update your project, (see “Updating Existing Projects” on page 19).
NOTE: If, for some reason, flashsecurity.txt is missing or was deleted from the project, the default
behavior is to apply Mode Bit 11 Full Protection to the entire program memory.
This information contains instructions on modifying flashsecurity.txt and appears at the beginning of
this file in PSoC Designer.
