From ae28b96ab9824474a8f5a808480fee3fe7db1f3a Mon Sep 17 00:00:00 2001 From: zwelch Date: Fri, 12 Jun 2009 01:40:03 +0000 Subject: Simplify and improve parport_handle_parport_port_command: - Show the port number to the user when asking for it or setting it. - Print an error if the parport_port has already been set. - Use parse_u16 helper to ensure the parport_port string parses correctly. git-svn-id: svn://svn.berlios.de/openocd/trunk@2209 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/jtag/parport.c | 21 ++++++++++++++++----- 1 file changed, 16 insertions(+), 5 deletions(-) (limited to 'src/jtag') diff --git a/src/jtag/parport.c b/src/jtag/parport.c index 4ee2202d..129caf0b 100644 --- a/src/jtag/parport.c +++ b/src/jtag/parport.c @@ -429,12 +429,23 @@ static int parport_quit(void) static int parport_handle_parport_port_command(struct command_context_s *cmd_ctx, char *cmd, char **args, int argc) { - if (argc == 0) - return ERROR_OK; + if (argc == 1) + { + /* only if the port wasn't overwritten by cmdline */ + if (parport_port == 0) + { + int retval = parse_u16(args[0], &parport_port); + if (ERROR_OK != retval) + return retval; + } + else + { + LOG_ERROR("The parport port was already configured!"); + return ERROR_FAIL; + } + } - /* only if the port wasn't overwritten by cmdline */ - if (parport_port == 0) - parport_port = strtoul(args[0], NULL, 0); + command_print(cmd_ctx, "parport port = %u", parport_port); return ERROR_OK; } -- cgit v1.2.3
