You mean a target defined in an openocd config file? I'm not sure it's needed to be able to connect. But you most definitely need one to be able to do anything, what else are you going to debug? > i have openup linux terninal and typed gdb As a separate reminder, you'll likely want to use a GDB configured for the target system you intend to debug, and not your host GDB. > then > target remote localhost:3333 > command was executed timeout error occured. > > but i can execute following command; > telnet localhost 4444 > > what will be the reason ? There's not nearly enough information in here to be able to figure that out. For starters, what is your target? How do you invoke openocd and what are the contents of any custom config files you're using? A full -d3 debug log may be necessary. You can also check that: 1. You've not changed the gdb_port from the default in your openocd config files. 2. You don't have any stale openocd processes running. 3. You don't have any other process listening to port 3333 (netstat -nlp may help) /Andreas ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
