679 - Lattice ispVM: Why do I get the warning "Cannot write to selected Working directory. Select another one." when I start the ispVM System software tool?

Description:

When you install your Lattice ispLEVER or Lattice Diamond software for the first time, the included ispVM software uses default paths for Device Database Location, Start Directory, Working Directory, and Log File Name.

The root directory for these paths may not match the actual root directory of your ispLEVER or Lattice Diamond software installation.

For example, the default ispVM prefix may point to  C:\ispTOOLS\ispvmsystem, whereas your actual ispLEVER ispVM installation may physically reside in  C:\ispTOOLS8_1\ispvmsystem.

Solution: 

To address this issue, you will need to modify the paths so they point to your actual installation of ispVM. To do so, follow the steps below:

  1. Start ispVM
  2. If the Files Locations window is not already showing, select Options-> File Locations
  3. Modify the root directory  for Device Database Location, Start Directory, Working Directory, and Log File Name to point to your actual ispVM root directory
  4. If you press the  Apply button, the path modification will only be valid for the current session of ispVM. To make sure that the modification is also valid for the next time you run ispVM,  press instead the Save button
