I am trying to debug a kernel over a remote serial console. I get Ignoring packet error .. kgdb page suggests that it might be due to the speed mismatch. i tried stty ispeed 9600 ospeed 9600 < /dev/ttyS0 on the development machine and have passed serial=0,9600n8 option and gdbbaud=9600 via lilo to the debug kernel.
when i run %stty speed on the development machine it still reports 38400. so i changed the gdbbaud and serial= values to 38400 on the test machine. even this doesn't work. any ideas?also on the development machine when i invoke %gdb bzImage gdb reports that bzImage is not an Executable file format and it is unable to recognize the format. what is the problem? -sridhar ps: i have tried redirecting the kernel messages( without patching it with kgdb) over the serial line and read it with minicom . that works fine.
