Hi,
Can I use the redboot gdb stub safely with program that go back and forth
between user and supervisor mode?
The first thing is that I'm think i always get the supervisor mode registers
in gdb. Is there any support for accessing the banked registers in gdb and
stubs?
What iam actually doing is debugging uClinux kernel on top of redboot. I has
to modify the uClinux kernel so that it doesnt install all the hardware
exception vectors (only irq and swi) and so far that worked pretty well but
now i'm wondering if the problem im seeing is in relation with the fact that
linux switch from svc to user mode
Thanks
