Function Documentation

gdb_interrupt_handler()

void gdb_interrupt_handler

(

DebugContext *

context

)

High-Level interrupt handler for GDB_Stub.

Allow the generic GDB interrupt handler to access the protected methods of this class.

Similar to the default interrupt_handler. Called by the entry function written in assembly (see debug/gbd/handler.asm) – these routines are installed in the constructor.

After preparing the data this function calls GDB_Stub::handle, which handles the communication with the host via the serial interface.

Optional:

Since this function should now also be triggered by the serial interrupt, the end of interrupt must be signaled.

Parameters

context

contains a pointer to the stack, which can be used to access the debug interrupt context.

Variable Documentation

instance

GDB_Stub* instance = 0

static

GDB instance.
