Detailed Description

for GDB_Stub Interrupt handler and its context

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.
