Good. I recommend to not use Eclipse when we troubleshoot the bug. > But when I'm connecting avr-gdb to simulavr, Connect() function stops to > execute and ReadByte() begins to execute (5-10 times per second) Does ReadByte() return some meaningful bytes or always -1? The command "$M" from GDB (probably caused by "load" command) may take a while to receive when ReadByte() is executed only 10 per second. > Then, I can see the timeout error in avr-gdb. ... File log.txt in your last mail indicates that the TCP connection is open and GDB did complete the handshake. Timeout error in avr-gdb is unlikely. Are you sure that the problem did occur then? Maybe it was run with "set remotetimeout 10000". (I cannot reproduce the problem. Tried clean version, fresh from GIT repository. GDB and simulavr launched from separate command-line windows. Not from Eclipse.) -- Petr Hluzin _______________________________________________ Simulavr-devel mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/simulavr-devel
