To All,
I and my collegue are learning to create new project is CCS. My collegeue created simple project to run from internal RAM CCS Version: 4.1.0.02000. He could build the project and debug it from internal ram. He provided me this project. I imported the entire his workspace and project to my PC. My CCS version is newer than his. His is CCS Version: 4.1.0.02000. Mine is CCS Version: 4.1.2.00027. When opening the workspace I got a following warning.
"The workspace 'C;\code\EnhancedAlarm' was created with a previous version of CCS. Workspace contains temporary data that changes from version to version. To load the project CCS needs to clean out thisdata. Click ok to load this work space....."
I click ok.. The workspace open. I build the project without any errro. Started debugging the project. The project did not got loaded in internal RAM.
See various information below.
Q.1 Can you tell me why I can not load the project into internal RAM and debug it? The memory display at 0x20000000 shows symbols but no code. All data is ???
Q.2 Do you know what settings I lost when imported the project to nwer version of CCS that prevents me from loading the project into internal RAM and debug?
Q.3 How can I attach file to this posting? Can I attache zip file, GEL file, cmd file, gel file etc to the posting? I tried to do that but, my explorer died. It will be very helpful if you can show a way to attach zip file or files etc. for posting a problem to the forum.
Many thanks for your assistance in this.
Please see below part of GEL file, CMD file and MAP file.

The GEL file indiocates that internal ram is enabled. See below.
