- Subject: some questions about kernel debugging
Dear all:
I enable kernel hacking options about kernel debugging on my mips platform.
I can successfully connect to the target board.
My question is:
1. why I cannot p/x the value of variable?
I have enabled CONFIG_ARCH_WANT_FRAME_POINTERS and CONFIG_FRAME_POINTER
but I still get the message which tell me "value optimized out".
did I miss anything?
my kernel version is 2.6.30.9?
appreciate your help,
miloody
