Dear,
I'm trying to debug Xenomai kernel with GDB and Qemu.
QEMU in emulation or KVM mode?
I'm using Qemu in emulation mode.
So, I launch
Xenomai in Qemu and make it waiting for GDB. Then I start GDB and
connect them to Qemu, make breakpoint at the desired function to debug
and start Xenomai. If the function belongs to the linux kernel, the
execution stop at the breakpoint. But, if the function belongs to the
Xenomai nucleus, GDB recognize the breakpoint at the execution but don't
stop.
Is Xenomai built as module or part of the main kernel image? The latter
is simpler to handle as you don't have to deal with modules as symbol
sources, find out their addresses, and load them at the right location.
Xenomai is built as a part of the main kernel.
Is it possible to debug Xenomai with GDB and Qemu?
Definitely.
Is it the good way to debug?
Thank you for your attention and your help.
Sincerely,
