[En-Nut-Discussion] branches/devnut_m3n: Makedefs.cm3-gccdbg should define debugging symbols

[Uwe Bonnes]

Hello,

is this the right place to send patches for the devnut_m3n branch?

Makedefs.cm3-gccdbg should define debugging symbols. That way, I can step
into the library, like:
 bt
#0  NutDeviceLookup (name=0x200002b0 "usart2") at
../.././nut/os/devreg.c:100
#1  0x08000e30 in NutRegisterDevice (dev=0x200002ac, base=0, irq=0 '\000')
    at ../.././nut/os/devreg.c:140
#2  0x08000026 in main () at candemo.c:94

./nut/Makedefs.arm-gccdbg uses -gdwarf-2. Is this also used for cortex-3?

Bye
