Function Documentation

◆ arm7_9_add_breakpoint()

int arm7_9_add_breakpoint	(	struct target *	target,
		struct breakpoint *	breakpoint
	)

Add a breakpoint to an ARM7/9 target.

This makes sure that there are no dangling breakpoints and that the desired breakpoint can be added.

Parameters

target	Pointer to the target ARM7/9 device to add a breakpoint to
breakpoint	Pointer to the breakpoint to be added

Returns: An error status if there is a problem adding the breakpoint or the result of setting the breakpoint

◆ arm7_9_add_watchpoint()

int arm7_9_add_watchpoint	(	struct target *	target,
		struct watchpoint *	watchpoint
	)

Add a watchpoint to an ARM7/9 target.

If there are no watchpoint units available, an error response is returned.

Parameters

target	Pointer to the ARM7/9 target to add a watchpoint to
watchpoint	Pointer to the watchpoint to be added

Returns: Error status while trying to add the watchpoint

◆ arm7_9_assert_reset()

int arm7_9_assert_reset ( struct target * target )

Asserts the reset (SRST) on an ARM7/9 target.

Some -S targets (ARM966E-S in the STR912 isn't affected, ARM926EJ-S in the LPC3180 and AT91SAM9260 is affected) completely stop the JTAG clock while the core is held in reset (SRST). It isn't possible to program the halt condition once reset is asserted, hence a hook that allows the target to set up its reset-halt condition is setup prior to asserting reset.

Parameters

target Pointer to an ARM7/9 target to assert reset on

Returns: ERROR_FAIL if the JTAG device does not have SRST, otherwise ERROR_OK

◆ arm7_9_deassert_reset()

int arm7_9_deassert_reset ( struct target * target )

Deassert the reset (SRST) signal on an ARM7/9 target.

If SRST pulls TRST and the target is being reset into a halt, a warning will be triggered because it is not possible to reset into a halted mode in this case. The target is halted using the target's functions.

Parameters

target Pointer to the target to have the reset deasserted

Returns: ERROR_OK or an error from polling or halting the target

◆ arm7_9_poll()

int arm7_9_poll ( struct target * target )

Polls an ARM7/9 target for its current status.

If DBGACK is set, the target is manipulated to the right halted state based on its current state. This is what happens:

State	Action
TARGET_RUNNING \| TARGET_RESET	Enters debug mode. If TARGET_RESET, pc may be checked
TARGET_UNKNOWN	Warning is logged
TARGET_DEBUG_RUNNING	Enters debug mode
TARGET_HALTED	Nothing

If the target does not end up in the halted state, a warning is produced. If DBGACK is cleared, then the target is expected to either be running or running in debug.

Parameters

target Pointer to the ARM7/9 target to poll

Returns: ERROR_OK or an error status if a command fails

◆ arm7_9_soft_reset_halt()

int arm7_9_soft_reset_halt ( struct target * target )

Issue a software reset and halt to an ARM7/9 target.

The target is halted and then there is a wait until the processor shows the halt. This wait can timeout and results in an error being returned. The software reset involves clearing the halt, updating the debug control register, changing to ARM mode, reset of the program counter, and reset of all of the registers.

Parameters

target Pointer to the ARM7/9 target to be reset and halted by software

Returns: Error status if any of the commands fail, otherwise ERROR_OK
