Be aware that Code Composer's debugger doesn't like it when the application starts from 0x1000. So you may need to switch to 0 while debugging ( Wiping out the bootloader ) before putting it back to 0x1000 for bootloading on to other splashbase boards.
User parameters are saved to the end of flash, the linker command file avoids this area.
