Hi Jun! Thank you very much for your reply! I very much appreciate it! I think I am getting a little confused now... I read your "Linux MIPS porting howto" (very informative, thanks a lot :-) and consulted some other documents about this and there it says to have a kernel command line such as "... gdb gdbttys=1 gdbbaud=115200". Now, should I just try to add "kgdb=ttys1" to that or replace the previous command with it. Sorry if I am asking a stupid question but this process is not very well documented... somehow... Again, thanks a lot for your help!!
