| |
Background: -----------
In the past, I have had to use the kernel serial debugger with the 2.2.14 kernel.
The steps I followed (if my notes are correct) were:
- in "make menuconfig", within "<Kernel Hacking>", select "<Kernel support for GDB>" - pass the additional options "gdb gdbttyS=1 gdbbaud=115200" to loadlin - wait for the message "Waiting for connection from remote gdb on ttyS1"
My question: ------------
Has any of this changed with the 2.4.x kernel? I'm currently playing with 2.4.19-pre9. Is there a "serial debugger" patch that has to be applied first, or is this support normally built-in?
The reason I ask is because I don't see the option "Kernel support for GDB", which leads me to think that maybe this functionality actually came from a patch that was applied on top of 2.2.14.
While I'm at it: is there a "better", or perhaps a "more popular" method of debugging the kernel?
Thanks,
Stephane Charette
