Hello ,
What do you mean by debug mode? Do you want to use the debug option in gcc to build the kernel (or) want to to debug the kernel using a debugger?

I need to buld the kernel with debug option and after that debug it with a debugger. But as first I do need to build it properly.
TIA
If you have a kernel w/ kgdb support, than this would be one with a 'unoffical' patch applied. Is this certain? If not, trying to get along with 'printk' and/or CONFIG_DEBUG_LL is probably easier.
Okay, but HOW do I enable building the kernel with debug option ? something like -O0 ? Where ? In makefiles or in menuconfig options ? TIA
I've found the answer in .config
CONFIG_DEBUG_INFO=y
bye
Hello ,
-O0 is for optimization. Use -g for generating debug information.
