I want to add a interface_mode command with only one parameter, default is
JTAG mode.
In configuration file, it will be as follow to use SWJ interface:
interface_mode swj
in jtag_register_commands in tcl.c, add:
register_command(cmd_ctx, NULL, "interface_mode",
handle_interface_mode_command,
COMMAND_ANY, "set debug interface mode [jtag|swj]");
And handle_interface_mode_command will be:
static int handle_interface_mode_command(struct command_context_s *cmd_ctx,
char *cmd, char **args, int argc)
{
if (argc != 1)
return ERROR_COMMAND_SYNTAX_ERROR;
int retval = ERROR_OK;
if (strcmp(*args, "jtag") == 0)
{
// jtag mode
set_jtag_intarface();
}
else if (strcmp(*args, "swj") == 0)
{
// swj mode
set_swj_intarface();
}
else
{
// mode not supported
LOG_ERROR("%s is not supported.", *args);
return ERROR_FAIL;
}
return ERROR_OK;
}
set_jtag_intarface and set_swj_interface will be implemented in core.c.
Is that OK?
