Therefore, a mechanism is needed to process the interruption. Now we build our program directly into the source code of programs U-BOOT. And we want to use interrupts. Could really do better to write our attachment (application) and use it as a "Standalone Applications? and already in the program to break as we need? .... please tell how to use the break to our processor (BlackFin 532)? ... how do we best get out of this situation?
