As I have understood, it is possible to write scripts in boot.scr. Can it be solved in this way:
- A standalone program/module is created and saved in the file system. This program access the WDT (watchdog) hardware and perhaps has some arguments for feeding the dog etc.
- The above program is accessed from boot.scr during boot-up, and starts/initiates the WDT.
- Once the fs is mounted and all other things are up and running, the program above can be used as WDT feeder by an application.
Is the above scenario realistic? Again, my idea is to not re-build any kernel och u-boot etc.
Has any ony done anything similar or have ideas on hotwo do this, please give me hints
