◆ allow_transports()

int allow_transports	(	struct command_context *	ctx,
		const char const	vector
	)

Called by debug adapter drivers, or affiliated Tcl config scripts, to declare the set of transports supported by an adapter.

When there is only one member of that set, it is automatically selected.

Definition at line 86 of file transport.c.

References allowed_transports, ERROR_FAIL, ERROR_OK, LOG_ERROR, LOG_INFO, session, and transport_select().

Referenced by COMMAND_HANDLER().

◆ COMMAND_HELPER()

COMMAND_HELPER	(	transport_list_parse	,
		char ***	vector
	)

Makes and stores a copy of a set of transports passed as parameters to a command.

Parameters

vector where the resulting copy is stored, as an argv-style NULL-terminated vector.

◆ get_current_transport()

struct transport* get_current_transport ( void )

Returns the transport currently being used by this debug or programming session.

Returns: handle to the read-only transport entity.

◆ transport_register()

int transport_register ( struct transport * new_transport )

Registers a transport.

There are general purpose transports (such as JTAG), as well as relatively proprietary ones which are specific to a given chip (or chip family).

Code implementing a transport needs to register it before it can be selected and then activated. This is a dynamic process, so that chips (and families) can define transports as needed (without needing error-prone static tables).

Parameters

new_transport the transport being registered. On a successful return, this memory is owned by the transport framework.

Returns: ERROR_OK on success, else a fault code.

◆ transport_register_commands()

int transport_register_commands ( struct command_context * ctx )

Definition at line 353 of file transport.c.

References NULL, register_commands(), and transport_group.
