I'm using Qemu in emulation mode.
What's your target arch? x84-64, x86-32, or some ARM or PPC etc.
The breakpoints match correctly the compiled code. Anyway, it must stop
at the breakpoint. No?
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
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.
OK. Check during runtime of the guest if the disassembly at the desired
breakpoint address matches the compiled code. Maybe there is some
Xenomai-core mailing list
