We are trying to upgrade software via the SCI interface using the TI Serial Flash Programmer PC software. When we tried to download software after we got the SCI mode working, we got to the point that the Programmer software succeeded to load the kernel (from what we understand, 'kernel A' as described in the flash programming notes) to the RAM and then seemed to load the application.
1. The program was apparently not actually loaded; when we loaded another version, the Programmer stopped at the beginning of loading the application. When we loaded the same version that was already burned on the board, the programming finished the process. What was missing to allow the flash to actually be programmed?
2. We then started over by totally erasing the board and then trying to see if programming worked. Now the kernel does not even load; SCM locked?
I saw something about this in one of your answers but since I am only a 'user' of this board and not a developer, I need help sifting through the material to find out what we need to do to burn the software on an erased board and on an already-burned board. Does something on the board have to be configured before the download can work?
3. Should we be using different software than the Serial Flash Programmer?
4. Please confirm that once this process works, the flash should be re-programmed and the board will come up with the upgraded software on the next normal (non-SCI) reset.
Thank-you -
