Detailed Description

MicroBlaze libdebugger implementation.

Macro Definition Documentation

◆ EXC_FRAME_PRINT

#define EXC_FRAME_PRINT	(	_out,
		_prefix,
		_frame
	)

Print the exception frame.

Function Documentation

◆ rtems_debugger_target_cache_sync()

int rtems_debugger_target_cache_sync ( rtems_debugger_target_swbreak * swbreak )

Target instruction cache sync. This depends on the target but it normally means a data cache flush and an instruction cache invalidate.

◆ rtems_debugger_target_configure()

int rtems_debugger_target_configure ( rtems_debugger_target * target )

Configure the target. This is architecture specific.

◆ rtems_debugger_target_disable()

int rtems_debugger_target_disable ( void )

Disable the target.

◆ rtems_debugger_target_enable()

int rtems_debugger_target_enable ( void )

Enable the target.

◆ rtems_debugger_target_exception_print()

void rtems_debugger_target_exception_print ( CPU_Exception_frame * frame )

Print the target exception registers.

◆ rtems_debugger_target_exception_to_signal()

int rtems_debugger_target_exception_to_signal ( CPU_Exception_frame * frame )

Return the signal for the exception.

◆ rtems_debugger_target_frame_pc()

uintptr_t rtems_debugger_target_frame_pc ( CPU_Exception_frame * frame )

Return the frame's program counter (PC).

◆ rtems_debugger_target_hwbreak_control()

int rtems_debugger_target_hwbreak_control	(	rtems_debugger_target_watchpoint	type,
		bool	insert,
		uintptr_t	addr,
		DB_UINT	kind
	)

Hardware breakpoints.

◆ rtems_debugger_target_hwbreak_insert()

int rtems_debugger_target_hwbreak_insert ( void )

Insert hardware breakpoints into the hardware.

◆ rtems_debugger_target_hwbreak_remove()

int rtems_debugger_target_hwbreak_remove ( void )

Remove hardware breakpoints from the hardware.

◆ rtems_debugger_target_read_regs()

int rtems_debugger_target_read_regs ( rtems_debugger_thread * thread )

Read the regosters.

◆ rtems_debugger_target_reg_pc()

uintptr_t rtems_debugger_target_reg_pc ( rtems_debugger_thread * thread )

Return the thread's program counter (PC).

◆ rtems_debugger_target_reg_sp()

uintptr_t rtems_debugger_target_reg_sp ( rtems_debugger_thread * thread )

Return the thread's stack pointer (SP).

◆ rtems_debugger_target_tcb_sp()

uintptr_t rtems_debugger_target_tcb_sp ( rtems_debugger_thread * thread )

Return the thread's TCB stack pointer (SP).

◆ rtems_debugger_target_thread_stepping()

int rtems_debugger_target_thread_stepping ( rtems_debugger_thread * thread )

The thread is stepping. Setup the thread to step an instruction.

◆ rtems_debugger_target_write_regs()

int rtems_debugger_target_write_regs ( rtems_debugger_thread * thread )

Write the regosters.
