My idea was to use the state_tables and JTAG_STATEMOVE command we
already have implemented in all drivers.
void jtag_add_statemove(tap_state_t end_state)
{
int retval;
if ((end_state != TAP_INVALID) && !tap_is_state_stable(end_state))
{
LOG_ERROR("BUG: TAP path doesn't finish in a stable state");
exit(-1);
}
jtag_prelude(end_state);
retval=interface_jtag_add_statemove(end_state);
if (retval!=ERROR_OK)
jtag_error=retval;
}
int MINIDRIVER(interface_jtag_add_statemove)(tap_state_t end_state)
{
jtag_command_t **last_cmd = jtag_get_last_command_p();
/* allocate memory for a new list member */
*last_cmd = cmd_queue_alloc(sizeof(jtag_command_t));
last_comand_pointer = &((*last_cmd)->next);
(*last_cmd)->next = NULL;
(*last_cmd)->type = JTAG_STATEMOVE;
(*last_cmd)->cmd.statemove =
cmd_queue_alloc(sizeof(statemove_command_t));
(*last_cmd)->cmd.statemove->end_state = end_state;
return ERROR_OK;
}
