I am trying to build an EFS (Flash System Image) from FreeScale iMX6.  Instructions from Documentation here:
http://www.qnx.com/developers/docs/660/index.jsp
To create a flash filesystem project:

  1.  From the main menu, select File > New > Project.
  2.  Expand QNX, then select QNX System Builder Project in the right. Click Next.
   3. Name your project and click Next.
   4. Specify whether you want to import an existing buildfile or create a generic file.
    5.Specify your target hardware (e.g., armle-v7).
   6. Click Finish. The IDE creates your new IFS project, which includes a generic .ifs image.
   7. In the editor, use the Add New Image icon in the System Builder editor's toolbar to create a new image element:
    8.To add an EFS image to the new IFS project, select either the option to import an EFS buildfile, or to create a 
generic EFS model.
    9.Now, that you have two images in the project, remove the empty IFS image that was created by default.
------------------------------------------------------------------------------------------------------------------------
-------------------
In step 6. The project doesn't create .ifs image, no images are created. If I clean/build, I get a .raw image
In Step 7. I don't see an new image icon or add new image feature in menu. I am in the QNX System Builder perspective. 
The image options under File menu, are new " add QNX build image", which if I select and click finish, I get Illegal 
Thread Access Error.
