Function Documentation

◆ assert_size()

assert_size	(	DebugContext	,
		24 *	8
	)

◆ 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.

Parameters

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

extern
