def_bool DEBUG_OCD
help
Write kernel log output directly into the ocd or to a serial port.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. For normal operation
it is not recommended because it looks ugly and doesn't cooperate
with klogd/syslogd or the X server. You should normally N here,
unless you want to debug such a crash.
# These options are only for real kernel hackers who want to get their hands dirty.
config DEBUG_LL
bool "Kernel low-level debugging functions"
depends on DEBUG_KERNEL
help
Say Y here to include definitions of printascii, printch, printhex
in the kernel. This is helpful if you are debugging code that
executes before the console is initialized.
config DEBUG_OCD
bool "Kernel low-level debugging via On-Chip-Debugger"
depends on DEBUG_LL
default y
help
Say Y here if you want the debug print routines to direct their
output to the UniCore On-Chip-Debugger channel using CP #1.
